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 […]

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

waste management 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 […]

Role of Waste-to-Energy in Waste Management

waste-dump

The rapid increase in population coupled with changing lifestyle and consumption patterns is leading to an exponential increase in global waste generation. Ironically, most of the wastes are dumped in open fields, along highways or burnt wantonly. Waste-to-energy is increasingly getting acceptance as an integral component of solid waste management hierarchy. What is Waste-to-Energy Waste-to-Energy […]

Bioenergy Sector in South Africa

South Africa is endowed with abundant renewable energy 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) […]

Pathways for Waste-to-Energy Conversion

WTE systems

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 […]

Trash Talk from 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 […]

Biogas from Industrial Wastes

Organic 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 […]

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 […]

What You Need to Know About Waste-to-Energy Processes?

WTE systems

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 […]

6 Top Benefits of Refuse Derived Fuels

RDF-Pellets

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 […]

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 […]
