What is Waste-to-Energy

Energy is the driving force for development in all countries of the world. The increasing clamor for energy and satisfying it with a combination of conventional and renewable resources is a big challenge. Accompanying energy problems in different parts of the world, another problem that is assuming critical proportions is that of urban waste accumulation. The quantity of waste produced all over the world amounted to more than 12 billion tons in 2006, which increased to 13 billion tons in 2011. The rapid increase in population coupled with changing lifestyle and consumption patterns is expected to result in an exponential … Continue reading

Fuel Pellets from Solid Wastes

MSW is a poor-quality fuel and its pre-processing is necessary to prepare fuel pellets to improve its consistency, storage and handling characteristics, combustion behaviour and calorific value. Technological improvements are taking place in the realms of advanced source separation, resource recovery and production/utilisation of recovered fuel in both existing and new plants for this purpose. There has been an increase in global interest in the preparation of Refuse Derived Fuel (or RDF) containing a blend of pre-processed MSW with coal suitable for combustion in pulverised coal and fluidised bed boilers. Pelletization of Urban Wastes Pelletization of municipal solid waste involves the … Continue reading

Waste-to-Energy Outlook for the 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 waste generation which is more than 2kg per day in some countries. The urban waste generation from the region has now crossed 150 million tons per year which has forced policy-makers and urban planners to look for sustainable waste management solutions, including recycling and waste-to-energy. Let … Continue reading

Insights into WTE Industry

Waste-to-Energy is the use of modern combustion and biochemical technologies to recover energy, usually in the form of electricity and steam, from urban wastes. These new technologies can reduce the volume of the original waste by 90%, depending upon composition and use of outputs. The main categories of waste-to-energy technologies are physical technologies, which process waste to make it more useful as fuel; thermal technologies, which can yield heat, fuel oil, or syngas from both organic and inorganic wastes; and biological technologies, in which bacterial fermentation is used to digest organic wastes to yield fuel. Global Scenario Around 130 million … Continue reading
