إعادة تدوير النفايات اإلكترونية في دول مجلس التعاون الخليجي

تزايد كمية النفايات الإلكترونية يثير مزيدا من الاهتمام على جدول الأعمال العالمي .في عام 2017، يتوقع أن يصل إنتاج النفايات الإلكترونية إلى 48 مليون طن في جميع أنحاء العالم. أكبر المساهمين في هذا الحجم هي دول متقدمة للغاية، مع المراكز الثلاثة الأولى من هذا الترتيب غير المشرف من نصيب النرويج وسويسرا وأيسلندا. ففي النرويج، ينتج كل ساكن 28.3 كيلوغراما من النفايات الإلكترونية كل عام. أما دول مجلس التعاون الخليجي في هذا الترتيب فهي ليست بعيدة عن الدول العشر الأولى، حيث تنتج كل من الكويت والإمارات العربية المتحدة 17.2 كيلوغرام من النفايات الإلكترونية للفرد سنويا. وتنتج المملكة العربية السعودية ،بتعدادها السكاني … Continue reading

Circular Economy in GCC: Potential, Prospects and Challenges

The concept of a circular economy has been gaining a lot of momentum on the agenda of many countries in recent years. In its core, it describes an economic model which opposes the current so-called linear economy, where output is produced, used and disposed at the end of its lifespan. In contrast, circular economy advocates suggest a model in which raw materials used during the life cycle of a good are completely reintegrated into the production process. Circular economy, therefore, means more than just to recycle your old appliances, but includes considerations about how to redefine products and services in … Continue reading

Recycling of Glass

Glass and bottles are a large component of waste due to their weight and density consisting of bottles, broken glassware, light bulbs and other items. The glass bottle use is not much declining due to rising consumers, high consumption and introduction of a variety of soft drinks and juices. Glass recycling is at a minimum in the Middle East due to lack of segregation, awareness and economical reasons. Management of glass bottles is a major challenge as it takes millions of years to degrade glass naturally. Glass bottles and jars are 100% recyclable and can be recycled endlessly without any … Continue reading

Waste Management Awareness in Oman: A Pilot Study

The four Rs (reduce, reuse, repurpose, and recycle) of waste management have not yet entered the everyday discourse of Oman, but does this mean that they are not part of everyday life in Oman? We think the people of Oman can help us to answer this question. To get a first-hand understanding of the degree of waste management awareness in Oman, a pilot study was designed, a questionnaire was prepared, and in a series of interviews with individual Omanis we recorded their responses. Insights into the Survey The questionnaire covered household consumption habits, food waste and other household waste, and awareness of … Continue reading

Recycling of E-Waste in GCC: Challenges and Opportunities

The growing amount of e-waste is gaining more and more attention on the global agenda. In 2017, e-waste production is expected to reach up to 48 million metric tons worldwide. The biggest contributors to this volume are highly developed nations, with the top three places of this inglorious ranking going to Norway, Switzerland and Iceland. In Norway, each inhabitant produces a massive 28.3 kg of e-waste every year. Not far behind the top ten of this ranking lie GCC member states, with both Kuwait and UAE producing each 17.2 kg e-waste per capita per year. Saudi Arabia with its many … Continue reading

Recycling Prospects in Saudi Arabia

The concept of waste recycling has been getting increasing attention in Saudi Arabia in recent years. The country produces around 15 million tons of municipal solid waste each year with an average daily rate of 1.4 kg per person. This rate is projected to double (30 million tons per year) by 2033 with current annual population growth rate of 3.4%. The major ingredients of Saudi Arabian municipal solid waste are food waste (40-51%), paper (12-28%), cardboard (7%), plastics (5-17%), glass (3-5%), wood (2-8%), textile (2-6%), metals (2-8%) etc. depending on the urban activities and population density of studied region.

A Holistic Approach to Tackling Food Waste Problem in Qatar

In a country that imports 90% of its food, discarded food accounts for about half of Qatar’s municipal garbage. These statistics point to the loss of millions of riyals each year, in the form of food wastage. The food in landfills rots to release greenhouse gases like methane which are responsible for the rise in temperatures which contributes to global warming. According to Project Drawdown, the global leader in quantifying climate change strategies, reducing food waste is the single greatest solution to reverse climate change, which could draw 87 gigatons of CO2 out of the atmosphere, way ahead of a global plant-based … Continue reading

Trends in Recycling of EPS Foam

Expanded polystyrene (EPS) foam, commonly known as styrofoam, the ubiquitous lightweight material used in packaging of electronic devices, food items and electric appliances, is popularly used because of its water and heat resistant properties. These properties likewise make it a preferred material for disposable food containers such as bowls, plates and coffee cups. Due to its popularity, the global demand for EPS foam and its production is steadily increasing.  According to GBI Research, the global demand for both polystyrene and EPS increased to 14.9 million tons in 2010 from 13 million tons in 2000.1 This is expected to further swell … Continue reading

Analysis of a Composting Facility

The composting process is a complex interaction between the waste and the microorganisms within the waste. The microorganisms that carry out this process fall into three groups: bacteria, fungi, and actinomycetes. Actinomycetes are a form of fungi-like bacteria that break down organic matter. The first stage of the biological activity is the consumption of easily available sugars by bacteria, which causes a fast rise in temperature. The second stage involves bacteria and actinomycetes that cause cellulose breakdown. The last stage is concerned with the breakdown of the tougher lignins by fungi. The composting process occurs when biodegradable waste is piled together … Continue reading

Making a Switch to Circular Economy

All forms of wealth and security, including climate stability, biodiversity, resource availability, soil fertility, air and water purity and health, are depleted by the systemic error of running a linear economy. Linear economics consumes the basis for future growth so what is now growing fastest is unproductive activity, inactivity and instabilities. The credit crunch marks the withdrawal of faith in growth-as-usual and any reliable revival of growth and prosperity requires a switch of vision. Circular Economics The future for growth is circular economics where more economic activity would mean a faster pace of change away from waste-making and towards looking … Continue reading
