Thermal Technologies for MSW-to-Energy Conversion

By | | , ,
Leave a comment

Thermal (or thermochemical) MSW-to-energy conversion systems consist of primary technologies which convert the municipal waste into heat or gaseous and liquid products, together with secondary conversion technologies which transform these products into more useful forms of energy, such as heat and electricity. A wide array of thermal waste-to-energy technologies are available to convert the energy stored in solid wastes into more useful forms of energy. These technologies can be classified according to the principal energy carrier produced in the conversion process. Energy carriers are in the form of heat, gas, liquid and/or solid products, depending on the extent to which … Continue reading →

Red Sea “Super Corals” – A Ray of Hope for Global Reef Survival

By | | ,
1 Comment

Coral reefs often known as the rainforests of the seas are a critical part of our ecosystem due to its role in providing coastal stability, species habitat, and nutrient cycling. Corals are known to share a symbiotics relationship with algae which provide them with nutrient byproducts from photosynthesis and in return the algae have can live in the host coral giving it its colour. These natural barriers protecting us against storms and floods are in threat from global warming as even a slight increase in the local average maximum temperature can activate coral stress response which can lead to increased … Continue reading →

Algae vs. Oil Spills and Climate Change: An Opportunity for Middle Eastern Seas

By | | , ,
1 Comment

Oil spills, marine pollution, and climate change have become global challenges, particularly acute in oil-producing regions. The Persian Gulf and coastal waters of Saudi Arabia, Kuwait, Qatar, and the UAE are areas with heavy concentrations of petroleum infrastructure, where any incident could trigger an environmental disaster. Nature itself may hold the solution: marine algae can cleanse water of petroleum products and absorb carbon dioxide on a massive scale. This has been demonstrated by scientists in various parts of the world’s oceans. Seas under threat The Persian Gulf serves as the heart of the global oil economy. Dozens of oil platforms, … Continue reading →

Climate change has been established as an actual, factual event that is changing everyone’s lives, and not for the better. Polar caps are melting, the temperature of the entire Earth is rising, and our oceans are filling with garbage. People across the world are responding in different ways, including reusing products and recycling others, but what about colleges and universities? What can they do to help the environment? There are several ways that colleges can make a positive impact on the environment, but one of the best ways is to move towards online education. Here’s why: It Reduces Electricity Use … Continue reading →

Saudi Arabia has one of the world’s highest per capita fuel consumption in the transportation sector. This is primarily due to lack of efficient public transportation and current fuel subsidy policy. The country is witnessing an escalating demand on its domestic energy needs and it is imperative on policymakers to devise policies for conservation of energy resources and reduction of GHGs emissions in the transportation sector. Adapting fuel efficiency standards will help Saudi Arabia country to bridge the gap with the developed countries. The enforcement mechanism for the establishment of Saudi fuel economy standards will lead to achievement of strategic … Continue reading →

أصبح التغير المناخي حقيقة واقعة في تونس التي تعاني الأمرين  لمجابهة مشاكل  التصحر وندرة المياه وتدهور الموارد الطبيعية. وبالرغم من إسهامها المحدود في انبعاثات غازات الدفيئة على مستوى العالم، إلا أن أخطار التغير المناخي الواقعة عليها قد تكون عالية التأثير و هو ما يسيل الكثير من الحبر حول مدى نجاعة السياسات المناخية بتونس. وضعت تونس، وهي رابع دولة عربية قدّمت مساهماتها المعتزمة المحددة وطنيا في مجال خفض الإنبعاثات من الغازات الدفيئة ، تغيّر المناخ في مرتبة متقدّمة على جدول أعمالها السياسي والاقتصادي باعتبارها  البلد الأول في المنطقة الذي ضمّن دستوره الوطني الجديد إقرارا بتغيّر المناخ تفرض من خلاله الدولة  الحق … Continue reading →

Securing Every Drop: The Role of Butterfly Valves in MENA Water Systems

By | | ,
Leave a comment

Water scarcity is one of the most pressing challenges facing the Middle East and North Africa (MENA). Rapid population growth, urban expansion, and climate change are putting unprecedented pressure on an already fragile water infrastructure. According to the World Resources Institute, 12 of the world’s 17 most water-stressed countries are located in the MENA region. Against this backdrop, many countries have had to rely on energy-intensive seawater desalination. Yet every drop of desalinated water comes with significant economic and environmental costs. This makes conserving and using existing water resources more efficiently just as strategically important as developing new sources. In … Continue reading →

Gas Vs Electric Mowers: Are You Ready to Go Green?

There are many factors to take into account when deciding whether to purchase an electric-powered lawn mower or a gas-powered lawn mower. Today there are more options than ever due to advances in technology in both gas motors and batteries. As you weigh your options you should consider the size of your lawn and how you wish to mow it. Gas-powered mowers Gas-powered motors have traditional gas engines that use gas tanks and oil reservoirs. When operating they produce carbon monoxide, also known as combustion exhaust, which is detrimental to the environment. Also, you have to make sure you have … Continue reading →

The Concept of Generalised Extended Producer Responsibility

By | | , ,
3 Comments

The notion of Extended Producer Responsibility (EPR) has been part of the waste policy for a long time, particularly within the OECD countries. According to the OECD, EPR “aims to make producers responsible for the environmental impacts of their products throughout the product chain, from design to the post-consumer phase” [1]. EPR alleviates the burden of Public Administrations for managing end-of-life products, while -if properly designed- incentivising waste prevention and recycling. Current Limitations of EPR After years of implementation it can be argued that Extended Producer Responsibility has not in fact been so extended. Several limitations are common: a) producer … Continue reading →

Solid waste management is considered to be one of the most severe environmental and civic problems in the Gaza Strip. Solid waste in the Gaza strip consists mainly of household waste, building debris, agricultural waste, industrial waste (mainly from worksites), medical wastes, and wastes from car workshops. Solid waste in the Gaza Strip is dumped in the same landfill without separation except for medical waste, which is dumped separately in the main Gaza landfill site. The solid waste generation rate varies between 0.35 to 1.0 kg/capita/day. Scale of the Problem Trash generation in the Gaza Strip varies between 830 to 894 tons/day … Continue reading →
