Principal Scientific Adviser Reviews New Waste‑Management Framework for Indian Cities

New Delhi – On Thursday, Professor Ajay Kumar Sood, the Principal Scientific Adviser to the Government of India, chaired a high‑level review of a freshly completed research project titled “Development of LCA Framework for Solid Waste Management (SWM) Technologies in India”. The meeting, held under the aegis of the PSA’s office, brought together scientists from IISc Bengaluru, IIT Madras and IIT (BHU) Varanasi.

The core of the project is a contextual Life Cycle Assessment (LCA) framework coupled with a web‑based greenhouse‑gas (GHG) calculator. In plain terms, the tool lets Urban Local Bodies (ULBs) plug in data about their waste‑handling practices – be it composting, anaerobic digestion, waste‑to‑energy incineration or landfilling – and instantly see the carbon footprint of each option.

Dr Parvinder Maini, the Scientific Secretary, underscored how the initiative dovetails with the Swachh Bharat Mission‑Urban. He stressed that without institutional mechanisms to spread such technology, the benefits would remain confined to a handful of cities.

The research team walked the audience through a series of case studies from Bengaluru, Mysuru, Tumakuru, Chennai, Delhi and Varanasi. These examples illustrated how the LCA model captures emissions from collection logistics, processing stages and even avoided emissions when waste is recycled or turned into biogas.

A short demo video showcased the GHG calculator’s interface. Users can toggle between scenarios, compare the net emissions of, say, a conventional landfill versus an anaerobic‑digestion plant, and view detailed breakdowns of methane, CO₂, NOₓ and black‑carbon outputs.

Beyond the numbers, the project put forward strategic recommendations – ranging from improving segregation at source to incentivising low‑carbon technologies – and drafted a national roadmap for a climate‑resilient, low‑emission waste‑management future.

According to the team, the app is built to be user‑friendly for municipal engineers. It automatically aggregates emissions from standard processes, highlights avoided emissions when alternatives are chosen, and visualises the “best‑practice” pathway that delivers the smallest carbon imprint.

While the calculator is still being piloted, officials said it could soon become a mandatory planning aid for ULBs across the country, helping them meet both Swachh Bharat targets and India’s broader climate commitments.
