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 […]

New Delhi’s Tryst with Rubbish
Have you seen the several storeys high landfill in Delhi at its border with Uttar Pradesh – Gazipur, a prime land! It’s a mountain of garbage now. How does the garbage reach the landfill and what will happen when this place is all filled up? Does our food waste also contribute to our garbage mountains? May be we all […]
Exploring Gasification of Municipal Solid Wastes
Gasification of municipal solid wastes involve the reaction of carbonaceous feedstock with an oxygen-containing reagent, usually oxygen, air, steam or carbon dioxide, generally at temperatures in excess of 800°C. It involves the partial oxidation of a substance which implies that oxygen is added but the amounts are not sufficient to allow the fuel to be completely […]
Waste as a Source of Energy
Wastes can be transformed into clean and efficient energy and fuel by a variety of technologies, ranging from conventional combustion process to state-of-the art plasma gasification technology. Besides recovery of substantial energy, these technologies can lead to a substantial reduction in the overall waste quantities requiring final disposal, which can be better managed for safe […]
Role of Reverse Logistics in Waste Management
Reverse logistics is a process whereby businesses can implement a sustainable waste management and become more eco-friendly through recycling, reusing, and reducing the amount of materials used. A more holistic view of reverse logistics includes reduction of materials in the forward system in such a way that fewer materials flow back, reuse of materials is […]
