WTE Prospects in Middle East

The high rate of population growth, urbanization and economic expansion in the Middle East is not only accelerating consumption rates but also increasing the generation rate of all sorts of waste. High-income Middle Eastern countries like Saudi Arabia, UAE, Qatar, Bahrain and Kuwait are counted as world’s largest waste producers in terms of per capita […]

Thermal Technologies for Biomass Conversion

A wide range of thermal technologies exists to convert the energy stored in biomass to more useful forms of energy. These technologies can be classified according to the principal energy carrier produced in the conversion process. Carriers are in the form of heat, gas, liquid and/or solid products, depending on the extent to which oxygen […]

Quick Summary of Waste-to-Energy Processes

A wide variety of waste-to-energy processes are available for realizing the potential of waste as an energy source, ranging from very simple systems for disposing of dry waste to more complex technologies capable of dealing with large amounts of municipal and industrial waste. These methods can be broadly divided into thermal and biological processes. Some […]

Biogas from Industrial Wastes

Biogas (or anaerobic digestion) technology is an attractive way to manage organic wastes in a sustainable manner. Organic waste includes a wide range of organic materials obtained from domestic, industrial and commercial operations. Most of the organic waste generated in developing countries is dumped into the landfills where it is not only responsible for large-scale greenhouse gas […]

Significance of Solid Waste Management

Some countries have achieved considerable success in solid waste management. But the rest of the world is grappling to deal with its wastes. In these places, improper management of solid waste continues to impact public health of entire communities and cities; pollute local water, air and land resources; contribute to climate change and ocean plastic […]

Gasification of Tannery Wastes

Wastes generated by the leather processing industries pose a major challenge to the environment. According to conservative estimates, about 600,000 tons per year of solid waste are generated worldwide by leather industry and approximately 40–50% of the hides are lost to shavings and trimmings. Everyday a huge quantity of solid waste, including trimmings of finished […]

Waste Crisis in Lebanon

Solid waste management in Lebanon has been hogging limelight globally in recent years. Unfortunately, Lebanon is struggling to solve the waste crisis with no permanent solution in sight.  The organic content in Lebanese MSW is around 50-55% which makes it a well-suited for composting and anaerobic digestion. Recyclables content is also good, though recycling is […]

Waste to Energy in Jordan

Waste-to-energy is getting increasing attention in Jordan because of the cheap and abundant availability of a wide range of biomass feedstock, including municipal solid waste, sewage, industrial waste etc. Municipal solid wastes represent the best feedstock for waste to energy plants  in Jordan. In terms of quantity per capita and constituents, the waste generated in […]

Role of Waste-to-Energy in SWM

According to recent estimates, the rapid increase in population coupled with changing lifestyle and consumption patterns is expected to result in an exponential increase in global waste generation of up to 18 billion tonnes by year 2020. Ironically, most of the wastes are disposed of in open fields, along highways or burnt wantonly. Waste generation […]

Biomass Energy Prospects in Southeast Asia

Southeast Asia, with its abundant biomass resources, holds a strategic position in the global biomass energy atlas. There is immense potential of biopower in Southeast Asian countries due to plentiful supply of diverse forms of wastes such as agricultural residues, woody biomass, animal wastes, municipal solid waste, etc. The rapid economic growth and industrialization in […]

Pathways for Waste-to-Energy Conversion

The conversion of waste-to-energy can proceed along three main pathways – thermochemical, biochemical and physicochemical. Thermochemical conversion, characterized by higher temperature and conversion rates, is best suited for lower moisture feedstock and is generally less selective for products. On the other hand, biochemical technologies are more suitable for wet wastes which are rich in organic […]

Renewable Energy in Jordan – Potential and Progress

Jordan is heavily dependent on oil imports from neighbouring countries to meet its energy requirements. The huge cost associated with energy imports creates a financial burden on the national economy. Electricity demand is growing rapidly, and the Jordanian government has been seeking ways to attract foreign investment to fund additional capacity. In 2008, the demand […]

Quick Glance at MSW-to-Energy Systems

Reduction in the volume and mass of solid waste is a crucial issue especially in the light of limited availability of final disposal sites in many parts of the world. Waste-to-Energy (WTE) or Energy-from-Waste (EfW) is the use of modern combustion and biochemical technologies to recover energy, usually in the form of electricity and steam, from urban […]

Enumerating Advantages of RDF

Solid waste is a growing problem in all countries, and a critical problem in almost all the cities of the developing world. Developed countries have in recent years reduced the environmental impact of solid waste through sanitary landfills and high-temperature incineration, as well as conserving natural resources and energy through increased recycling, but the volume […]

Bioenergy in South Africa

South Africa is endowed with abundant renewable resources in the form of biomass, solar and wind energy. The Government’s White Paper on Renewable Energy Policy, released in 2003, supports the development of alternative energy systems with an ambitious target of generating 10,000 GWh green electricity by 2013. The introduction of Renewable Energy Feed-in-Tariff (REFIT) has […]

Waste-to-Energy Industry Trends

The quantity of waste produced all over the world amounted to more than 1.3 billion tonnes in 2012, with estimates of up to 2.2 billion tonnes by 2025. The rapid increase in population coupled with changing lifestyle and consumption patterns is expected to result in an exponential increase in solid waste generation. Ironically, most of […]

Garbage Woes in India

An American produce 2.1 kg of garbage per day against 0.6 kg for an Indian, according to a 2009 study by the National Sanitary and access to water-governmental organization, the CPHEEO (Central Public Health and Environmental Engineering Organization ). Yet the country with a total of 1.2 billion people takes the cake in terms of volume of […]

Waste to Energy Industry – Trends and Forecasts

Incineration, with energy recovery, is the most common waste-to-energy method employed worldwide. Over the last five years, waste incineration in Europe has generated between an average of 4% to 8% of their countries’ electricity and between an average of 10% to 15% of the continent’s domestic heat. Around 130 million tonnes of municipal solid waste […]
