Lessons From Tokyo, New York, 3-Pronged Plan In Focus As Capital Races To Clear Legacy Waste, Pg3

Key Highlights:

• The Municipal Corporation Delhi (MCD) discussed waste management strategies with World Bank experts to address Delhi's legacy waste.
• The meeting focused on adopting global best practices from Tokyo, New York, and Barcelona models.
• A 3-pronged approach for Delhi was proposed, centering on decentralised processing and transport, a sustainable waste treatment mix, and institutional strengthening.
• The objective is to enhance MCD's operational efficiency, establish financial sustainability, and reduce atmospheric emissions.
• Deadlines for clearing the Okhla and Bhalswa landfills are set for December this year, with the Ghazipur landfill targeted for December next year.

Detailed Insights:

• Tokyo's model features an extensive waste processing system with Waste-to-Energy units for scientific processing of municipal waste.
• New York City's model employs an externalized waste management system, utilizing private agencies for waste transportation and processing, including movement to facilities outside the city.
• Barcelona's Zero Waste Plan 2021-2027 emphasizes decentralized waste management facilities to alleviate pressure on transportation systems.
• The proposed 3-pronged approach for Delhi aims to integrate these global insights into local requirements and conditions.
• Legacy biomining is a crucial part of the current plan to develop a sustainable waste treatment mix and clear existing landfills.
• Progress towards clearing the landfills has been impacted by heavy rainfall, affecting the processing of daily waste.
• The Solid Waste Management Rules, 2026, encourage ward-level processing where recyclables and organics are handled at the source to prevent open dumping or burning.
• Central Pollution Control Board (CPCB) guidelines mandate that municipal solid waste undergoes manual and mechanical segregation at Material Recovery Facilities (MRF) before being sent to landfills.
• A previous recommendation to implement utility tariffs for solid waste management, to be levied with property tax, was put on hold due to public opposition.

Key Concepts Involved:

• Legacy Waste: Decades-old, untreated municipal solid waste accumulated in landfills, posing significant environmental and health hazards.
• Waste-to-Energy (WtE): A process that generates energy, such as electricity or heat, from the incineration of waste, particularly non-recyclable, high-calorific municipal solid waste.
• Biomining: The scientific process of excavating, treating, and segregating aged municipal solid waste from landfills to recover valuable resources and reclaim land.
• Material Recovery Facility (MRF): A specialized plant designed to receive, separate, and prepare recyclable materials for sale to manufacturers as raw materials.
