CM Lays Foundation for Waste Processing and Biogas Plants
CONTEXT
- New waste processing facilities, along with a 300btonne perbday biogas plant, are being established in Delhi to process biodegradable waste and reduce dependence on landfill disposal.
- The initiative aims to tackle the city’s growing waste burden while promoting scientific and sustainable waste management.
KEY HIGHLIGHTS
- Waste processing facilities are planned at Okhla, Singhola and Ghazipur with different units designed to handle significant quantities of municipal waste each day.
- The proposed biogas facility at Ghazipur will process biodegradable waste and convert organic matter into useful biogas instead of sending it directly to landfills.
- The initiative seeks to reduce pressure on major landfill sites such as Okhla, Bhalswa and Ghazipur, while also making land occupied by accumulated waste available for other uses.
- Scientific waste management goes beyond waste collection. It requires source segregation, recycling, composting, biomethanation, material recovery and scientific treatment of residual waste.
- Converting organic waste into biogas can support the circular economy by recovering energy and nutrients while reducing methane emissions from uncontrolled decomposition of organic waste.
KEY CONCEPTS
- Biomethanation: A biological process in which microorganisms break down organic matter in the absence of oxygen, producing biogas and nutrient rich digestate.
- Biogas: A renewable gaseous fuel generated through the anaerobic decomposition of organic matter, consisting mainly of methane and carbon dioxide.
- Waste to Energy: The recovery of usable energy from municipal waste through processes such as anaerobic digestion, incineration and refuse derived fuel systems.
- Circular Economy: An economic approach that seeks to minimise waste by keeping materials and resources in productive use through reuse, recycling, recovery and regeneration.
WAY FORWARD
- Delhi should adopt an integrated “segregate, process, recover and reuse” approach.
- This should be supported by decentralised waste processing facilities, stronger municipal capacity and effective enforcement of source segregation.
