Subject: Science & Technology - Energy and Environment
Sub-topic: Waste-to-Energy Technologies (Incineration, Gasification, Pyrolysis, Anaerobic Digestion/Biomethanation, RDF), Municipal Solid Waste Management Rules 2016, Swachh Bharat Mission, SATAT Scheme, Environmental Concerns, Circular Economy
Mains GS Paper-III: Environment and Technology - waste management, renewable energy, waste-to-energy challenges and opportunities; Prelims focus: technologies, SWM rules, policy schemes.
Waste-to-Energy (WtE) sits at the intersection of urbanisation, energy security, and environmental protection. UPSC Prelims tests specific technologies (incineration vs gasification vs pyrolysis vs biomethanation), the municipal solid waste management framework (SWM Rules 2016), and Swachh Bharat Mission targets. Mains questions focus on India's poor waste segregation record, the economic viability of WtE plants, the environmental debate around incineration (dioxin emissions vs methane avoidance), and the role of WtE in the circular economy. The examiner's favourite framing is: "Is waste-to-energy a solution or a problem for India's waste management crisis?"
Waste-to-Energy (WtE) refers to the process of generating energy (electricity, heat, or fuel) from non-recyclable waste materials. It is a key component of the waste management hierarchy - coming after reduce, reuse, and recycle but before landfill disposal. WtE can reduce...
