تحسين الوضع الاقتصادي للمجتمعات عن طريق تعزيز مشاريع إعادة التدوير

 

 تعتبر البلديات و المجالس المحلية المسئول المباشر عن إدارة ملف النفايات الصلبة في المدن حول العالم للحفاظ على المدن نظيفة. ففي الوقت التي تحتل فيه التكنولوجيا المتوفرة (جمع النفايات، النقل، إعادة التدوير، التخزين، المعالجة)، تزداد النداءات الدولية لإعادة النظر إلى مجال إدارة النفايات الصلبة كأداة لحل العديد من المشاكل الاقتصادية، الإجتماعية، و البيئية. و من هذه الأصوات الرئيس الأمريكي السابق "بيل كلينتون" عندما صرح في المؤتمر السنوي لمبادرة كلينتون العالمية عام 2010

" إذا أردتم محاربة التغير المناخي، تحسين الصحة العامة، إيجاد فرص عمل للفقراء و خلق مناخ مناسب للروّاد، فإن أفضل الطرق للوصول لهذا الشيئ هو إغلاق مكبات النفايات"

 

فيجب على السلطات أن تنظر إلى ملف إدارة النفايات الصلبة بمنظور أشمل بحيث يشمل تحسن عام في صحة الناس و البيئة، استخدام أمثل للمصادر (موارد الطاقة) و تحسين الوضع الإقتصادي. لهذا أصبحت إدارة النفايات الصلبة تحد صعب للجهات المختصة، رجال الأعمال، و المواطنين، فإدارة النفايات الصلبة تحتاج إلى "خلطة سحرية" تنمزج فيها السياسة الإدارية، المسئولية الإجتماعية، القطاع التجاري، و المواطنين. 

 

فنجاح تطبيق نظام فعّال لإدارة النفايات الصلبة يعتمد بشكل كبير على عوامل محلية و إقليمية متعددة في المجالات الاقتصادية، الاجتماعية، و السياسية في المجتمع المحلي. فباللإضافة إلى نظام إدارة يشمل جميع الحلول المتوفرة، ففهم جيد للآلية التي تؤثر فيها العوامل السياسية، الاجتماعية، و الاقتصادية مهمة لتطوير استراتيجية فعّالة لإدارة النفايات الصلبة. فعلى الجهات المسئولة النظر إلى هذا الملف كفرصة للنهوض بالوضع الاقتصادي للمجتمع من خلال خلق آلاف فرص العمل و إنشاء مجال جديد للاستثمار.

 

فمن أجل التأثير على الطبقة العامة من الناس تجاه إعادة تدوير المخلفات، يجب عليهم أن يشعروا بصورة مباشرة بالفائدة التي تعود عليهم، لذلك كمرحلى أولى يجب تغيير الصورة السيئة في مخيلاتهم عن هذا المجال عن طريق حملات التوعية و المبادرات و الدراسات التفصيلية لكي يشعروا بحجم الفرصة و فوائدها.

 

الفيديو التالي لمشروع إنشاء وحدة إعادة فرز للنفايات الصلبة في مدينة رفح (فلسطين). تم تنفيذ المشروع عن طريق جمعية أصدقاء البيئة  و بتمويل من الوكالة اليابانية للتنمية، فعلي الرغم من الجدل القائم في هذا المجال حول فاعلية المشروع، فقد خلقت العديد من فرص العمل للنساء و ساعدت على تقليل كميات النفايات المرسلة لمكب صوفا. إنها خطوة جيدة في الاتجاه الصحيح و لكن كان الأولى، قبل إنشاء وحدة الفرز، دراسة الحلول و الخيارات للنفايات المفرزة في نهاية خط الانتاج حيث أن هناك الآلاف الأطنان من النفايات المكدسة بسبب عدم وجود أي طريقة لإعادة تدويرها بعد عملية الفرز.

Community Engagement in Recycling Initiatives in Qatar

The current state of environmental custodianship in Qatar leaves much to be desired from the national government and other institutions that publicly endorse initiatives with much fan-fare but do not commit to sustained action. My previous piece titled “Environmental Initiatives in Middle East – Challenges and Remedies” illuminated some of these gaps, but did not provide a detailed description of what underpins this trend and possible solutions might look like. Thus, this article seeks to delve deeper into how state institutions and civil society in Qatar may be able to work cooperatively in staving off further environmental degradation, especially with regards to waste management and recycling.

I believe that real success will be achieved through popular buy-in and a paradigm shift towards recognizing the interconnectedness of humans with their surroundings, which can be encouraged through education. Perhaps more importantly, there needs to be a public acknowledgement that all individuals residing in Qatar have a vested interest in pushing for greater environmental protection enforcement and accountability. In a region that is already faced with a lack of potable water and arable land, allowing the existing course to be maintained is not only risky, it is flat-out dangerous to the nation’s survival.

An Uphill Battle, But a Necessary One

Individuals that either live in or visited a Gulf Cooperation Council (GCC) nation, especially a hydrocarbon-rich rentier state like Qatar, are probably quite familiar with the inadequacies of current recycling initiatives. As someone who has visited the country on three different occasions I can tell you that I have searched high and low for something resembling a recycling bin, can, or other receptacle but to no avail, save for a few located in Education City. One might imagine this to be exceptionally jarring coming from the hyper-attentive, green-obsessed Washington, DC where trash and recycling cans typically are placed together on streets and in buildings.

Further adding to my chagrin is the apparent disconnect between high level, widely publicized recycling improvements and the realities (and consequences) manifesting among general society. For example, last year there was much excitement surrounding the announcement of upcoming environmental reforms in July 2014, but it appears nothing further came to fruition.

The article touches upon some of the apparent hindrances for recycling programs and other environmental initiatives: bureaucracy; paperwork; budgetary constraints. I would add to this list based upon personal experiences: general apathy towards recycling; inaccessibility of bins; perception of additional costs to conducting business.

Fair enough – I acknowledge that some of these issues are out of citizens’ and expats’ hands, but that is no excuse for giving up. The predicted 6.8% GDP growth spurred by the upcoming 2022 FIFA World Cup and hydrocarbon exports will surely put further pressure on an already fragile ecosystem and lead to an uptick in waste production. This is not meant to stoke unnecessary fear, but the equation here is straightforward; more people present in Qatar, more trash will be created from residential and commercial zones. As noted by fellow EcoMENA contributor, Surya Suresh, the nation presently possesses one solid waste facility at Mesaieed and three landfills devoted to particular items, which now seem to be overwhelmed by growing waste inputs.

Possible Solutions: Personal and Community Action

Given this lag in state responses to the existing recycling crisis and future issues stemming from it, readers may be asking what they can do to help. At the personal level, I would encourage Qatari residents, as well as others in neighboring nations, to begin with educating themselves about the current state of recycling initiatives and conducting an inventory of their daily waste generation. EcoMENA website offers a variety of informative pieces and external resources useful to individuals seeking more information.

My latter point about doing a personal inventory is about consciousness-raising about how we each contribute to a wider problem and identifying means of reducing our impact on the environment. Examples from my own life that I believe are applicable in Qatar include counting the number of plastic bags I used to transport groceries and replacing them with a backpack and reusable bags. I also frequently re-appropriate glass jars for storing items, such as rice, spices, and coffee – make sure to wash them well before reuse! It has taken me several years to get to past the social stigmas surrounding reusing containers and to cultivate the future planning to bring my reusable bags with me, but knowing my actions, aggregated with those of my friends and family, positively affect the environment is quite rewarding and reinforces good behavior. Give it a shot and see what happens.

Furthermore, it may be beneficial for the community at large to begin discussing the topic of recycling and what they would like to see, rather than solely wait on state agencies to address issues. Doing so could initially be formulated on a level that many Qatari residents are probably most familiar with: their place of employment, apartment, or neighborhood. After all, if individuals, specifically employers, are expected to bear the increased costs associated with improved recycling then an understanding of what people want is necessary in hopefully resolving issues effectively and with greater community enthusiasm.

Because of the nature of nation-states’ institutions typically being reactive entities and incapable of being aware of every societal problem, it is up to community-level groups to voice their concerns and be committed to change. Organizations such as the Qatar Green Building Council and the Qatar Green Leaders, offer a variety of informative pieces and training services that may help in establishing dialogues between groups and the government. Perhaps this is too idealistic right now, but Qatari residents have organized popular support for other initiatives, notably in the initial pilot recycling program in 2012. Now let us make that a sustained commitment to recycling!

مقدمة في عملية التسميد

إن عملية التسميد هي  عبارة عن تفاعل معقد بين النفايات والكائنات الحية الدقيقة المتواجدة داخلها . الكائنات الدقيقة التي تنفذ هذه العملية تنقسم إلى ثلاث مجموعات: البكتيريا والفطريات، والفطريات الشعاعية . الفطريات الشعاعية هي شكل من أشكال البكتيريا مثل الفطريات التي تفتت المواد العضوية .المرحلة الأولى من النشاط البيولوجي هو استهلاك السكريات المتوفرة بسهولة عن طريق البكتيريا، مما يسبب ارتفاعا سريعا في درجات الحرارة . تليها  المرحلة الثانية التي تسبب فيها  البكتيريا والفطريات الشعاعية  انهيار السليلوز . المرحلة الأخيرة هي المرحلة  المعنية بإنهيار اليغنينس "lignins" الصلبة من قبل الفطريات .

الحلول الوسط لهذه العملية تتخلص  بالتسميد بكلفة منخفضة دون التهوية الإجبارية ، أما تكنولوجياً استعمال أنظمة أكثر تقدماً باستخدام الهواء و الحرارة كتغذية إجبارية . النباتات الأساسية في عملية التسميد  قادرة على  التعامل مع أكثر من 100.000 طن سنوياً  من النفايات القابلة للتحلل ، ولكن عادة ما تكون سعة النبات  حوالي 10.000 إلى 30.000 طن سنويا.

يجب فصل النفايات القابلة للتحلل قبل عملية  التسميد: نفايات الطعام النقية فقط  ، نفايات الحديقة، ورقائق الخشب، وبعض الورق حسب مدى مناسبته لإنتاج نوعية جيدة من السماد . ويمكن تصنيف منهجية التسميد هذه إلى ثلاث أقسام  رئيسية  : السماد اللاهوائي ، الكمر الهوائي، و التمسيد بواسطة الكائنات الحية الدقيقة " مثل الديدان " . في التسميد اللاهوائي، تتحلل المواد العضوية في غياب الهواء .  و من الممكن جمع المواد العضوية في حفر و تغطيتها  بطبقة سميكة من التربة وتركها من ستة إلى ثمانية أشهر .  السماد الذي تشكل ليس بالضرورة أن يكون قد تحول بشكل تام ربما سيحتوي على بعض  تكتلات  " aggregates "  .

الكمر الهوائي هي العملية التي يتم من خلالها  تحويل النفايات العضوية بوجود الهواء  إلى سماد أو مغذي للسماد  ، ويمكن أن تكون من أنواع مختلفة. الأكثر شيوعا هي طريقة التكويم، حيث تقسم المادة العضوية إلى ثلاثة أنواع مختلفة، ثم توضع في حفرة كومة فوق الأخرى و تغطى بطبقة رقيقة من التربة الجافة أو الأوراق . تحتاج هذه الكومة إلى أن تخلط كل أسبوع ، وتحتاج حوالي ثلاثة أسابيع ليأخذ التحوّل منحاً جدياً . هذه العملية تقريبا نفس طريقة الحفرة، ولكنها تحتاج حفراً مخصصة . ينبغي القيام بالخلط كل 15 يوماً ، وليس هناك وقت ثابت لتأكيد جاهزية السماد .

يستخدم بيركلي الطريقة التقنية و كثيفة المجهود كما أن لديه متطلبات دقيقة للمواد التي يتم تحويلها إلى سماد . المواد القابلة للتحلل بسهولة، مثل العشب، والمواد نباتية، وما إلى ذلك، يتم خلطها  مع فضلات الحيوان بنسبة 1:2  . و يجهز السماد عادة في غضون 15 يوماً .

يتضمن التسميد بواسطة الكائنات الحية الدقيقة استخدام ديدان الأرض كمفاعلات و محفزات حيوية لعملية التسميد . ويتم ذلك في حفر مصممة خصيصا حيث يحتاج دودة الأرض الى التكاثر و تكوين مجتمعات حيوية  أيضا. التسميد بواسطة الكائنات الحية الدقيقة  هو خيار قائم على الدقة ويتطلب الإشراف على العمل من قبل خبير . كما أنه خيار عالي التكلفة .

على كل حال , خلافاً للخيارين أعلاه هي عملية عديمة الرائحة مما يجعلها الخيار الأفضل للمناطق السكنية .  كما أن  نسبة  تحويلها للمواد إلى سماد عالية للغاية ، لذلك جودة المنتج النهائي عالية جدا مع  وجود مغذيات دقيقة  والمغذيات صغيرة ايضا .  يحتوي المنتج النهائي أيضا على ميزة أنه يمكن أن يجفف ويخزن بأمان لفترة أطول من الزمن.

يحتاج تسميد النباتات إلى بعض أو كل الوحدات التقنية التالية: الفتاحات الحقيبة، فواصل مغناطيسية و / أو الباليستية، غرابيل (منخل)، القطاعات، معدات المزج و الخلط ، ومعدات التحويل وشبكات الري، وأنظمة التهوية وأنظمة الصرف الصحي، المرشحات الحيوية ، وأجهزة الغسيل، وأنظمة التحكم، وأنظمة التوجيه.

تحدث عملية التسميد عندما تتراكم النفايات القابلة للتحلل جنبا إلى جنب على شكل  هيكل يسمح لانتشار الأوكسجين مع محتوى المادة الجافة مسببا بيئة مناسبة لنمو الميكروبات.  درجة الحرارة تزداد بزيادة الكتلة الحيوية وذلك بسبب النشاط الميكروبي وخصائص عزل المواد المكدسة . غالبا ما تصل درجة الحرارة من 65 درجة مئوية إلى 75 درجة مئوية في غضون بضعة أيام ثم تنخفض ​​ببطء. هذا الارتفاع في درجة الحرارة يعجل القضاء على مسببات الأمراض وبذور الحشائش.

SAFE-Q: Be a Part of Food Waste Research Project in Qatar

SafeQ-Project-QatarDistribution of food is quite different and more challenging than other consumer products since the distribution operation must ensure the food product maintains its quality and safety while it is transported downstream on the food chain until it reaches the consumer. For example, temperature control is a critical aspect of food distribution as failure to maintain it at the prescribed level will result in deterioration of the quality or even risk the safety of the food product.

On the other hand, owing to the globalised distribution networks and the advances in food processing and packaging technologies as well as the improvements in storage and distribution infrastructure, the geographical locations where food is grown, processed, and consumed are becoming increasingly decoupled. As a result, global food supply chains are becoming longer and more complex than non-food supply chains because of the need to assure the quality and the safety of the products throughout their journey from farm to fork. The inefficiencies in food supply chain operations and changing consumer demands around food products have resulted in an increased global concern across academia, industry, and the public about the rise of food waste.

What is Safe-Q Project?

SAFE-Q or Safeguarding Food and Environment in Qatar is a research project funded by the QNRF, aiming to develop perspectives on food waste as well as its impact on food security in Qatar. The objectives of the SAFE-Q project are:

  • to systematically study and develop a typology of the causes of food waste occurring the distribution of food in Qatar
  • to examine the changing trends in consumption of food in relation to their implications on waste occurring in Qatar’s food supply chains
  • to synthesize and develop a holistic understanding of the food waste generated in the supply and the demand perspectives
  • to develop policy recommendations to reduce and eliminate where possible the waste occurring during the distribution and the consumption of food in Qatar

SAFE-Q is run by an international team of researchers from Georgetown University School of Foreign Service in Qatar, Cranfield University (UK), Brunel University (UK), University of Bradford (UK), and Western Sydney University (Australia) collaborating on factors driving food waste and how they can be mitigating to reduce and eliminate where possible the food waste. The SAFE-Q project is running from January 2015 to January 2018 and over the course of the project the researchers have collaborated with many organisations in Qatar, including but not limited to EcoMENA, Hamad bin Khalifa University, United Nations Environment Programme.

Why should you care?

Qatar is located in a region that has a limited capacity to be self-sustaining in food as much of the country consists of low, barren plains that are covered with sand and subject to intense heat over dry and humid seasons. Although recent efforts to grow food locally have proven successful, they are yet to reach substantial yields: the self-sufficiency percentage is still in single figures. Importing 90% of the food consumed in the country, Qatar also faces a significant food waste problem originating from many factors: weather conditions, poor demand planning, lack of logistics infrastructure, consumption habits, and so on. Whilst the agricultural capacity in the country is being increased to improve food security, there is something else we can do: identify the factors relevant to food waste and quantify them.

The SAFE-Q research team conducted 64 interviews with food chain actors such as farmers, importers, distributors, retailers, hotels, and catering businesses as well as consumers and employees of governmental and non-governmental organisations over the past two years and identified 61 factors related to food waste. All these factors and their definitions can be found on https://blogs.commons.georgetown.edu/safeq/factors-relevant-to-food-waste/

What do we expect to achieve?

SAFE-Q contributes to the implementation of the “Qatar National Vision 2030”, focusing on the long-term sustainability of the food supply chains. We expect to better understand the organisational and social influences that can promote food security in Qatar as it is on its path to set an example for the rest of the countries in the region in their efforts to become more sustainable and improve their food security.

food-waste-project-qatar

There are many factors driving food waste and we understand them individually, but we do not know the interactions between them and the system-wide effects. With your help, we will quantify the relationships between factors affecting food waste and develop policy recommendations around them in a systematic way to reduce the food waste. Your participation in our survey will allow us to establish the strength of these relationships and inform policy makers as they prioritise their policies to address the food waste problem as an integral part of the efforts to improve food security.

The Paper Bag Boy of Abu Dhabi

Abdul Muqeet, also known as the Paper Bag Boy, has risen from being just another ordinary student to an extra-ordinary environmentalist. At just ten years old, Abdul Muqeet has demonstrated his commitment to saving the environment in United Arab Emirates and elsewhere. 

Inspired by the 2010 campaign “UAE Free of Plastic Bags”, Abdul Muqeet, a student of Standard V at Abu Dhabi Indian School, applied his own initiative and imagination to create 100% recycled carry bags using discarded newspapers. He then set out to distribute these bags in Abu Dhabi, replacing plastic bags that take hundreds of years to degrade biologically. The bags were lovingly named ‘Mukku bags' and Abdul Muqeet became famous as the Paper Bag Boy.

Abdul Muqeet’s environmental initiative has catalyzed a much larger community campaign. During the first year, Abdul Muqeet created and donated more than 4,000 paper bags in Abu Dhabi. In addition, he has led workshops at schools, private companies and government entities, demonstrating how to create paper bags using old newspapers. His school along with a number of companies in Abu Dhabi adopted his idea by exchanging their plastic bags for paper bags.

Abdul Muqeet was one of the youngest recipients of Abu Dhabi Awards 2011, for his remarkable contribution to conserve environment. The awards were presented by General Sheikh Mohammad Bin Zayed Al Nahyan, Crown Prince of Abu Dhabi and Deputy Commander of the UAE Armed Forces. In 2011, Abdul Muqeet was selected to attend the United Nation’s Tunza conference in Indonesia where he demonstrated his commitment for a cleaner environment through his paper bag initiative. He is actively involved in spreading environmental awareness worldwide, especially UAE, India, USA and Indonesia.

 

Abdul Muqeet continues to make headlines for his concerted efforts towards a plastic-free environment, and has been widely covered by leading newspapers in UAE and other countries. He tirelessly campaigned for the Rio+20 summit, urging world leaders to commit to the Green Economy. “Plant more trees; use less water; reuse and recycle; always remember that everything in this world can be recycled but not time,” offers Abdul.

He has been remarkably supported by his parents and siblings throughout his truly inspiring environmental sojourn. Abdul Muqeet’s monumental achievements at such a tender age make him a torch-bearer of the global environmental movement, and should also inspire the young generation to protect the environment by implementing the concept of ‘Zero Waste’.

Waste-to-Energy in Jordan: Potential and Challenges

landfill-jordanEffective sustainable solid waste management is of great importance both for people’s health and for environmental protection. In Jordan, insufficient financial resources, growing population, rapid urbanization, inadequate management and lacking of technical skills represent a serious environmental challenge confronting local government. At the same time, energy remains Jordan’s top challenge for development. The energy needs to be produced in a sustainable way, preferably from renewable sources which have a minimum environmental impact. To face the future problems in waste management, as well as securing the demand of renewable energy, it is necessary to reuse the wasted resources in energy production.

Jordan has definitely acknowledged that making affordable energy solutions available is critical to support industries, investment, and attain sustainable growth. One option is to use solid waste to generate electricity in centralized plants. Waste-to-energy has been recognized as an effective approach to improve recycling rates, reduce the dependence on fossil fuels, reduce the amount of materials sent to landfills and to avoid pollution.

Waste-to-Energy Potential

According to recent statistics, Jordan population stands at around 9.5 million. The estimated municipal waste generated according to the last five years average production is around 3,086,075 ton/year. This huge amount of waste generated is not only a burden, but a potential resource for use in energy production. Considering the country average waste composition 40% is organic waste e.g. avoidable and unavoidable food waste (1,200,000 ton), 10 % are recyclable e.g. paper, plastic, glass, ferrous metals and aluminum (300,000 ton) and 50% are suitable for incineration e.g. garden and park waste, wood and textiles (1,500,000 ton) with high calorific value and energy potential (8.1 MJ/Kg) that is capable to produce electricity 340 kWh/ton waste. The high organic waste is suitable for methane gas capture technologies which is estimated at 170 m3/ton waste.

Technology Options

Nowadays, there are many technologies available which makes it possible to utilize these energy potentials. The major alternatives conventional technologies for large scale waste management are incineration, landfilling and anaerobic digestion. These technologies are affordable, economical visible and associated with minimum environmental impact. The production of electricity is combined with greenhouse gas (GHG) emissions, according to the current energy situation (90% of the country energy produced from fossil fuel), the country emission factor is around 819 CO2-eq/kWh. However, the use of waste to energy solutions is considered to be a clean and definitely the amount of GHG emitted is a lot less than the gases generated by ordinary practices (open dumping and unsanitary landfills).

Construction of an incineration plant for electricity production is often a profitable system even though the installation cost is high since production of electricity often leads to a large economic gain. Landfill gas utilization avoids the release of untreated landfill gases into the atmosphere, and produces electricity to sell commercially in an environmental friendly manner. However, landfilling is associated with methane production. Methane is a potent GHG, contributing 21 times more to global warming than carbon dioxide.

Anaerobic digestion technology is another option. Anaerobic digestion not only decrease GHGs emission but also it is the best technology for treatment of high organic waste through converting the biodegradable fraction of the waste into high-quality renewable calorific gas. Currently, with the growing use of anaerobic technology for treating waste and wastewater, it is expected to become more economically competitive because of its enormous advantages e.g. reduction of pathogens, deactivation of weed seeds and production of sanitized compost.

alghabawi-landfill-jordan

Sorting at the place of generation and recycling e.g. paper, plastic, glass and metals needed to be practiced at the country level or at least where these technologies implemented. Incinerated waste containing plastics (not sorted) releases carbon dioxide, toxic substances and heavy metals to the atmosphere and contributes thereby to climate change and to global warming.

Challenges to Overcome

Waste-to-energy technologies offer enormous potentials as a renewable energy sources and to mitigate climate change in Joran. However, these technologies pose many challenges to the country and discussion makers. Currently, the waste sector is administrated by the government. Poor regulation and insufficient financial resources are limiting the available options toward adapting these new technologies. Private investments and collaboration with the private sector is the key solution in this regard.

Recycling of PET Plastic Wastes

Like all other modern urban centers, the Middle East also faces challenges in environmental protection due to tremendous tonnage of waste produced in different forms. The gross urban waste generation from Middle East countries exceeds 150 million tons per annum, out of which 10-15 percent is contributed by plastic wastes. The burgeoning population, growing consumption, and an increasing trend towards a “disposable” culture, is causing nightmares to municipal authorities across the region and beyond.

Plastic consumption has grown at a tremendous rate over the past two decades as plastics now play an important role in all aspects of modern lifestyle. Plastics are used in the manufacture of numerous products such as protective packaging, lightweight and safety components in cars, mobile phones, insulation materials in buildings, domestic appliances, furniture items, medical devices etc. Because plastic does not decompose biologically, the amount of plastic waste in our surroundings is steadily increasing. More than 90% of the articles found on the sea beaches contain plastic. Plastic waste is often the most objectionable kind of litter and will be visible for months in landfill sites without degrading.

Recycling Process

After PET plastic containers are collected they must be sorted and prepared for sale. The amount and type of sorting and processing required will depend upon purchaser specifications and the extent to which consumers separate recyclable materials of different types and remove contaminants.

Collected PET plastic containers are delivered to a materials recovery facility to begin the recycling process. Sorting and grinding alone are not sufficient preparation of PET bottles and containers for re-manufacturing. There are many items that are physically attached to the PET bottle or containers that require further processing for their removal. These items include the plastic cups on the bottom of many carbonated beverage bottles (known as base cups), labels and caps.

Dirty regrind is processed into a form that can be used by converters. At a reclaiming facility, the dirty flake passes through a series of sorting and cleaning stages to separate PET from other materials that may be contained on the bottle or from contaminants that might be present. First, regrind material is passed through an air classifier which removes materials lighter than the PET such as plastic or paper labels and fines.

The flakes are then washed with a special detergent in a scrubber. This step removes food residue that might remain on the inside surface of PET bottles and containers, glue that is used to adhere labels to the PET containers, and any dirt that might be present. Next, the flakes pass through a “float/sink” classifier. During this process, PET flakes, which are heavier than water, sink in the classifier, while base cups made from high-density polyethylene plastic (HDPE) and caps and rings made from polypropylene plastic (PP), both of which are lighter than water, float to the top.

After drying, the PET flakes pass through an electrostatic separator, which produces a magnetic field to separate PET flakes from any aluminum that might be present as a result of bottle caps and tennis ball can lids and rings. Once all of these processing steps have been completed, the PET plastic is now in a form known as “clean flake.” In some cases reclaimers will further process clean flake in a “repelletizing” stage, which turns the flake into “pellet.” Clean PET flake or pellet is then processed by reclaimers or converters which transform the flake or pellet into a commodity-grade raw material form such as fiber, sheet, or engineered or compounded pellet, which is finally sold to end-users to manufacture new products.

Significance of E-Waste Management

Electronic waste (or e-waste) is the fastest growing waste stream, and its disposal is a major environmental concern in all parts of the world. More than 50 million tons of e-waste is generated every year with major fraction finding its way to landfills and dumpsites. E-waste comprises as much as 8% of the municipal solid waste stream in rich nations, such as those in GCC. Globally only 15 – 20 percent of e-waste is recycled while the rest is dumped into developing countries. However, in the Middle East, merely 5 percent of e-waste is sent to recycling facilities (which are located in Asia, Africa and South America) while the rest ends up in landfills.

What is E-Waste

The term ‘e-waste’ stands for any electrical or electronic appliance that has reached its end-of-life, such as refrigerators, washing machines, microwaves, cell phones, TVs and computers. Such waste is made up of ferrous and non-ferrous metals, plastics, glass, wood, circuit boards, ceramics, rubber etc. The major constituent of e-waste is iron and steel (about 50%) followed by plastics (21%), and non-ferrous metals (13%) like copper, aluminum and precious metals like silver, gold, platinum, palladium etc. E-waste also contains toxic elements like lead, mercury, arsenic, cadmium, selenium and chromium.

E-waste is different from municipal and industrial wastes and requires special handling procedures due to the presence of both valuable and expensive materials. Recycling of e-waste can help in the recovery of reusable components and base materials, especially copper and precious metals. However, due to lack of recycling facilities, high labour costs, and tough environmental regulations, rich countries either landfill or export e-waste to poor countries which is illegal under the Basel Convention.

Health Hazards

Recycling techniques for e-waste include burning and dissolution in strong acids with few measures to protect human health and the environment. E-waste workers often suffer from bad health effects through skin contact and inhalation. Workers, consumers and communities are exposed to the chemicals contained in electronics throughout their life cycle, from manufacture through use and disposal. The incineration, land-filling, and illegal dumping of electronic wastes all contribute toxic chemicals to the environment.

Electronics recycling workers have been shown to have higher levels of flame retardants in their blood, potentially from exposure to contaminated indoor air. Similar exposures are likely for communities where recycling plants are located, especially if these plants are not adequately regulated. Much of the electronics industry in the Middle East, Europe and North America has outsourced manufacturing and disposal to developing countries of Southeast Asia, China and India. Uncontrolled management of e-wastes is having a highly negative effect on local communities and environment in these countries.

E-Waste Recycling and Metal Industry

Electrical and electronic equipment are made up a wide range of materials including metals, plastics and ceramics. For example, a mobile phone may contain more than 40 elements including base metals like copper and tin, special metals such as cobalt, indium and antimony, and precious metals like silver, gold and palladium. Infact, metals represents almost one-fourth of the weight of a phone, the remainder being plastic and ceramic material. Taking into account the fact that worldwide mobile device sale totaled 1.8 billion in 2010, this will translate into significant metal demand each year.

If we consider the high growth rate of electronic devices, including cell phones, TVs, monitors, MP3 players, digital cameras and electronic toys, it becomes obvious that these equipment are responsible for high demand and high prices for a wide range of metals. These metal resources are available again at final end-of-life of the device which could be used for manufacture of new products if effective recycling methods are implemented.

Mining plays a vital role in the supply of metals for electrical and electronic industry. The environmental impact of metal production is significant, especially for precious and special metals. For example, to produce 1 ton of gold or palladium, 10,000 tons of carbon dioxide is generated. If recycling processes are used to recover metals from e-waste, only a fraction of CO2 emissions will occur, apart from numerous other benefits.

Waste Management Implications of 3D Printing

The rapid deployment of 3D printing is one of the most exciting developments since the appearance of the smart phone. This is technology with some serious potential to change how and where goods are manufactured, transforming supply chains. The New Scientist has gone so far as to herald 3D printing, also known as additive manufacturing, as ushering in a second industrial revolution. But is anyone thinking about how what this new development means for the waste sector?

Whilst the technology is already being put to some dubious uses, the ability to manufacture pretty much anything wherever and whenever it’s needed is certainly appealing. Interest isn’t confined to those frustrated inventors whose imaginations have been constrained by the tools they can fit in the garden shed; there’s likely to be take-up from businesses, householders – and even space agencies, apparently.

Insights into 3D Printing

By building up layer upon layer of material, a 3D printer can produce objects to any pattern, up to the maximum size it can handle. However, the applications to which these objects can be put to may be limited by the physical properties of the materials that will inputted in to 3D printers – the equivalent of the ink in the printers we’re all familiar with. Clearly, you can’t print a toaster if your 3D printer only uses plastic – but an oven knob, or even a wind-powered robot with dozens of moving parts, is no problem.

A quick scan of 3dprinter.net helpfully outlines the different methods 3D printers are able to deploy, which I’ve summarised here. Each appears to require its own TLA (Three Letter Acronym). Perhaps in the future terms such as Stereolithography (SLA), Fused Deposition Modelling (FDM), Selective Laser Sintering (SLS) and PolyJet photopolymer will become as ubiquitous as DVD and VHS have been in the past. Each of these techniques is compatible with a selection of materials, primarily plastics – but some are able to use metals, ceramics or even play-dough.

Environmental Implications

Moving significant amounts of manufacturing away from factories (predominately in Asia) to our own door steps will no doubt have profound impacts on the balance of goods and services across the globe. The economic and social implications of the technology have the potential to be significant– as do the environmental implications.

There is potential for greenhouse gas emissions savings from reduced shipping – not just cutting the number of products that make the long journey across the seas from China, but also reducing road freight. Fewer trucks on the motorways could be one of the unexpected effects 3D printing. But what are the waste management issues associated with mass deployment such technologies. And if we are future gazing, is their deployment consistent with the ‘zero waste economy’ envisaged by governments across the Middle East?

For those who haven’t yet thought too hard about what the technology is; think of it like the ‘replicator’ devices as featured in Star Trek. The replicator was a machine capable of creating objects by voice command, from what appeared to be thin air. 3D printing is only a shade less magical.

Waste Management Perspectives

3D printing is something of a double-edged sword when it comes to waste. It creates new recycling problems, but has considerable potential to help prevent waste. It could even be an outlet for recycled plastics. The opportunity for DIY repairs, especially to everyday items that we might otherwise decide were uneconomic to fix, appears enormous.

But with the higher profile that waste management has these days, I feel that we ought to be making 3D printing the first technology to be designed with recycling in mind. The waste management industry is a service industry; and typically it has had to adapt retrospectively to technology changes that it has not been able to influence. After more than a decade, we’re still catching up with the introduction of plastic milk bottles in lieu of glass. But this reactive approach clearly isn’t the best way to achieve a zero waste economy.

3D printing offers numerous challenges and opportunities to the waste management industry. As we, as a society, become more aware of material security, I’d suggest that the best approach would be for the waste management industry to engage positively with the designers and manufacturers of the 3D printing devices, trying to identify opportunities to ensure that the circular economy doesn’t become an afterthought.

The most appealing possibility would be if the machines could recycle waste polymers themselves, and re-use them as feedstock. Could we see a scenario where the machines become the recycling facility, thus greatly reducing the need for even the print medium to be transported? Bringing the nascent 3D printing industry together with experts in waste management could help to make this new technology contribute to rather than challenge our ambitions for a zero waste economy.

أسلوب حياة أخضر

green-lifestyle-arabicتبني "أسلوب حياة أخضر" هو محاولة لترشيد استغلال الفرد أو المجتمع للموارد الطبيعية عن طريق تغيير أساليب النقل واستهلاك الطاقة، واستخدام المياه وغيرها. ويعنى أسلوب الحياة الأخضر بتلبية الاحتياجات البيئية والاجتماعية، والاقتصادية الحالية دون المساس بقدرة الأجيال المقبلة على تلبية احتياجاتها. ويعد انخفاض حجم البصمة البيئية أو الكربونية هو النتيجة الطبيعية لأسلوب المعيشة المستدامة.

ويعتبر تلوث المياه، وتلوث التربة، وتلوث الهواء، والتخلص من النفايات والمحافظة على الموارد الطبيعية، وحماية الحياة البرية من التحديات البيئية الرئيسية التي تواجه البشرية. ولكلٍ منا دور يمكن أن يلعبه لتحقيق الاستدامة، وذلك من خلال تبني أسلوب حياة خضراء. وفيما يلي بعض النصائح التي يمكن أن تساعد في خلق بيئة صحية لك ولعائلتك، وللأرض كذلك:

  1. اتبع/ي التسلسل الهرمي للتعامل مع النفايات: يمكن تحقيق ذلك من خلال التدرج ابتداءً من تقليل الاستهلاك، ثم إعادة الاستخدام ثم إعادة تدوير ما تبقى.
  2. جرب/ي تغيير استخدام الاشياء: وذلك بتحويل النفايات إلى مواد أو منتجات ذات جودة أو قيمة أعلى من السلعة الأصلية، على سبيل المثال تحويل كيس من البلاستيك إلى بطانة داخلية لحاويات القمامة أو تحويل عبوة بلاستيكية إلى حاضنة بذور.
  3. حول/ي المواد العضوية إلى سماد: حيث يمكن انتاج السماد بتخمير المواد العضوية لإضافة المواد المغذية لتربة حديقة المنزل وتقليل نفاياتك المنزلية في نفس الوقت.
  4. أعد/أعيدي استخدام المياه: على الرغم من أهمية المياه كمورد لا يمكن الاستغناء عنه إلا أن محدوديتها تقضي بضرورة تدويرها و إعادة استخدامها؛ كاستخدام المياه الرمادية -بعد معالجتها -في نظام التدفق في المراحيض، وفي ري الحدائق. كما يوفر تجميع مياه الأمطار مصدرا اخر من المياه ذات النوعية الجيدة.
  5. بادر/ي بترشيد استخدام الطاقة: تعتبر الطاقة هي القوة الدافعة للتنمية، ويمكن القيام ببعض الممارسات للتقليل من هدرها كإطفاء أجهزة الكمبيوتر ليلاً، واستبدال المصابيح بتلك الموفرة للطاقة وتجنب وضع الأجهزة في وضع الاستعداد في حال عدم الحاجة لها.
  6. أعد/أعيدي التفكير في حاجتك للمياه المعبأة في عبوات بلاستيكية: لابد أن نتنبه إلى أن عبوات المياه البلاستيكية تستغرق آلاف السنين لتتحلل.لذا من الأجدر الاستغناء عنها بعبوة قابلة لإعادة الاستخدام.
  7. حاول/ي إعادة تدوير الهواتف المحمولة القديمة: يتم الاستغناء عن مئات الملايين من الهواتف المحمولة في كل عام مما يتسبب بإدخال العديد من المواد السامة إلى الأنظمة البيئية، في حال التخلص منها في مكبات النفايات المنزلية. هناك العديد من المشاريع التي تقوم بإعادة تدوير الهواتف ,أغلبها لتمويل مبادرات نبيلة.
  8. أعد/أعيدي تدوير الألومنيوم والزجاج: يمكن انتاج عشرين علبة ألمنيوم معاد تدويرها بنفس كمية الطاقة اللازمة لتصنيع علبة واحدة جديدة. وبالمثل، فإن كل طن من الزجاج المعاد تدويره يوفر ما يعادل تسعة غالونات من زيت الوقود اللازم لصنع الزجاج من المواد الخام.
  9. تجنب/ي استخدام الأكياس البلاستيكية: يتم استهلاك حوالي تريليون كيس في جميع أنحاء العالم كل عام مما يتسبب بأضرار عديدة في الأنظمة البيئية. ويمكن الاستعاضة بأكياس القماش القابلة للتحلل والتي يمكن إعادة استخدامها.
  10. نمي الأفكار: المعيشة المستدامة ليست مهمة صعبة المنال. يمكن لأشياء بسيطة، مثل زرع شجرة، أن تحدث فرقا ملموسا.

Recycling Attitudes in Saudi Arabia: A Survey

recycling-bin-jeddahThe waste management and recycling industry in Saudi Arabia is underestimated source of income. The continued increase in population and industrial development in the Kingdom has increased individual waste generation manifolds in the past few decades. The shortage of recycling industries in Saudi Arabia cost around SR 40 billion. The focus of Saudi recycling industry is plastic, papers and metals. If recycling industry targeted only plastic and paper and metals they can meet the need of the Saudi market efficiently. According to Arab League, recycling industry can save over 500 million SR just from iron, paper and plastic waste. The distribution of recycling companies is manly in big cities which make sense for the huge expected amount of waste products. There are several recycling companies operating in the big cities such as Riyadh, Jeddah and Dammam.

The new orientation of Saudi Arabia as a country is toward the global investment as per Vision 2030 released by Chairman of the Council of Economic and Development Affairs Mohammad bin Salman bin Abdulaziz Al-Saud.  The envisioned industrial growth of Saudi Arabia emphasizes the need to adopt modern recycling practices and encourage recycling attitude in public. 

Recycling Attitude in Saudi Arabia

The government did its part by encouraging recycling industry and while I was searching I noticed that there are many recycling companies in the Kingdom.  The question is not why the recycling attitude is not active or obvious, rather than how to make it a daily habit? At the beginning, I did a personal interview with few people in their 50-60 years old about recycling and why they should do it? The answers were disappointing because of lack of knowledge and awareness. Then I thought to switch to the young generation who are more educated and knowledgeable.  

I did a short survey to get a sense of young generation recycling attitude in Saudi Arabia. The survey was addressed to the University students in the age group of 18-24 years. I asked about several issues and whether if they agree with the recycling act or not? And if there are recycling services nearby where they live? The survey showed that majority of people acknowledged the importance of recycling act and would like to contribute.  

charts-ecomena_page_1

The survey showed that 74% of the sample think that recycling is very important but 45% of them recycle their house waste sometimes, while 44% don’t recycle at all. The challenge for 50% of the people on survey sample was the lack of recycling containers near where they live. However, around 15% of the sample think that sorting material is difficult while 12% think that recycling is not important.

Key Takeaways

It seems that majority of the young generation in Saudi Arabia accept the fact that recycling is a healthy choice and important to the environment but lack the facilities or containers other than embedding the attitude of recycling in their daily behavior. The need to embed the healthy recycling behavior is very important especially in this era of economic challenge. To enhance the recycling act, we should start from school to implant recycling importance in education. Although decision makers are predominantly from the older generation but discussing the present and future issues should be always directed to the young generation since they represent majority of the population in Saudi Arabia. As per latest data, the population of Saudi Arabia is 32,384,951, with median age of 28 years old and 15 person per km2 population density. The urban population represents 78% of Saudis with 1.5 percent growth rate.

The global issues associated with unbalanced environment should be more clear to the public. The global warming, the plastic virtual life, how many years until all these products degraded and do not affect the microflora and other creatures. The importance of diversity in creatures and soil, air, water microorganisms. Why we should care when we through stuff without sorting? Why recycling is a sign of high manners? All these questions and more should be answered and included in education.  

The other major step is to establish environmental center under the government supervision to provide containers and production lines. The step of environmental care center establishment should be accompanied with recycling industry business broadcasted on all sort of media. Social media such as Snapchat, Twitter, Facebook and Instagram became the broadcasting tool for the young generation. Using the media nowadays is necessity as a part of transparency. Applying transparency is an essential key to gain people trust and attention to their contribution toward any case. Making recycling attitude as an obvious contribution of people encourages them to continue the healthy act.  

Waste Management Perspectives for Egypt

Egypt occupies 7th position in the list of countries with the most mismanaged plastic waste, according to a recent report published in Science magazine. The report was based on data collected in 2010 and one must wonder whether the results of the report would have been different if the zabbaleen had been allowed to continue their work unhindered.

A History of the Zabbaleen

The zabbaleen, or garbage collectors, are the descendants of farmers from Upper Egypt who moved to Cairo in the 1940s. Together with another migrant group, they have made a living in Cairo collecting, sorting, salvaging, and recycling the waste of the city's nearly 20 million residents. With the help of NGOs, the zabbaleen recycled up to 80% of the waste they collected, more than three times the amount of waste recycled by garbage collectors in major cities in developed nations. The zabbaleen collected the garbage free of charge; they were part of Cairo's informal public sector. Their work was not supported by the government. Their income came from selling the recyclable material and from the pigs they raised on the organic waste. Many residents also gave monetary tips to the garbage collectors. This meager income barely supported the zabbaleen, who live together in different settlements around the city, all of them extremely poor.

Believing the zabbaleen's system to be backwards and unhygienic, in 2003, the government sold contracts to three multinational companies (and one local company) to collect Cairo's waste, pushing the zabbaleen out of the system. These companies were required to recycle only 20% of the waste collected, the other 80% making its way to landfills. It did not take long for residents to complain about this new service. They now had to pay for their garbage collection and that did not include door-to-door pick-up. There were not enough bins in the streets to hold all the waste and streets quickly filled with the overflowing garbage. The new companies simply could not keep up with the waste being produced. Not only did this have a devastating effect on the waste management situation in Cairo, it destroyed the zabbaleen's way of life as they lost access to the garbage that was the foundation of their economic activities. At one point, the private companies realized they needed the zabbaleen and tried to subcontract them, but the zabbaleen were highly underpaid and the system failed. Some residents, though, continued to hire the zabbaleen on their own.

Adding to both the city's garbage woes and the plight of the zabbaleen, in 2009, in response to the H1Ni influenza outbreak, the government ordered the culling of all the zabbaleen's pigs. These pigs were an essential part of the zabbaleen's recycling program. The pigs consumed all of the organic waste that was sorted from the garbage. When they lost their pig herds, the zabbaleen stopped collecting organic waste and the effect was felt almost immediately. Again, residents complained about the trash piling up on the streets. The trash piles became home to rats and disease. And once again, the zabbaleen suffered as they were no longer able to earn enough money to support themselves and had lost an important food source.

Change is in the Air

Since the 2011 revolution, many changes have taken place in Egypt, spurred on by environmentally-minded individuals, small businesses, and new government ministers. One of the more hopeful changes involves the collection of garbage. The government has finally implemented a proposal for officially employing the zabbaleen, replacing the international companies with smaller zabbaleen-run companies. Once registered, the local companies are given uniforms, government vehicles and business training from an NGO. The system had a test-run and debuted in a few areas late last year. If successful, there are plans to expand over the next two years. This is good news for Cairo's waste management and even better news for the zabbaleen.

Other private-sector initiatives are tackling recycling as well.  Recyclobekia is a new company that offers electronic waste recycling services. The company collects, sorts, and dismantles e-waste – old laptops, computers, cameras, phones, and more – and in return companies and individuals are given credit for an online shop or even cash if they recycle more than 500 kg of waste. GreenTec is an exciting recycling initiative that offers Automated Recycling Machines. With these machines, individuals can deposit their plastic water bottles and receive credit for their mobile phones. Another new venture coming out of Cairo is Refuse, a company that upcycles plastic bags and creates backpacks, tote bags, laptop covers, and other accessories with this waste. They also offer workshops to teach others how to upcycle.  Gamayit El-Misbah El-Mudii, started in 2005, provides free collection and recycling of paper, plastic, glass, and other items. They collect from individuals, schools, and businesses. Resala, a charity organization, also offers recycling services. As these initiatives and companies continue to grow, so will the awareness and action of individuals in terms of waste management and recycling.

Individual Action

While our local and national authorities attempt to improve the collection and recyling of our waste at the city level, it is important to remember that we as individuals can do a lot as well. The first and simplest action we can take it to sort our trash into organic and non-organic waste. Our garbage collectors, whoever they may be, will appreciate this effort and it will keep any paper or board waste clean so that it can be recycled. Once you've sorted your trash, make sure it's getting recycled. If the zabbaleen do not collect in your area, contact one of the organizations listed above. The most important action we can take is to reduce the amount of waste we are creating in the first place. Less waste produced means less waste needing to be managed. We can start by refusing to use or purchase disposable plastic. Bring your own reusable bags to the supermarket so that you don't need the plastic ones. Invest in a water filter and a reusable bottle so you can drink your tap water and skip the plastic water bottles. Avoid buying food packaged with polystyrene; it's not recyclable. Read this guide to a plastic-free life and search other websites for tips and ideas on reducing plastic waste. You'll find that most of the suggestions will be better for your health and the health of our environment, and at the same time, save you money. If we all do our part by taking these steps, perhaps Egypt won't make the top ten list of worst plastic offenders again.
