Waste Management Capacity Expansion Key To Curb Plastic Pollution

India needs to increase its waste management capacity and ensure universal access to disposal to tackle rising plastic pollution, according to the founder of The Ocean Cleanup, a Netherlands-based non-profit that develops technologies to remove plastic waste from the oceans. The organisation has announced an initiative to deploy barriers on the Trombay and Malad waterways in Mumbai to stop plastic from reaching the Arabian Sea and the Indian Ocean. The deployment is scheduled before the arrival of the monsoon season and aims to intercept debris close to source points.

The barriers are expected to collect at least 62 tonnes (t) per year once fully operational. The devices will be modular and placed like LEGO pieces, while some sites will use excavators and others will use conveyor belts to remove accumulated waste. The structures have been designed to withstand heavy monsoon rains and to give cities time to improve long term disposal systems.

A 2024 study published in Nature found that India is the world’s biggest contributor to plastic pollution, accounting for nearly 20 per cent of global plastic waste. The country generates nine point three million (mn) tonnes (t) of plastic waste annually, of which three point five mn t are mismanaged and leak into the environment each year. Limited access to collection systems and rapid population growth have been cited as drivers that prevent waste management systems from keeping pace with consumption.

Marine plastic pollution threatens food safety, human health and coastal economies and can damage mangroves and coral reefs. Collected waste will be sorted by material and recyclability to minimise residues that cannot be repurposed, and kilogram (kg) is used on first reference. Mumbai was chosen because surveys indicate it releases about five mn kg of plastic into the Arabian Sea and Indian Ocean annually, affecting 220 km of coastline, 152 sq km of mangroves, 107 protected species and nearly one point nine mn livelihoods. The organisation plans to expand the approach to other coastal cities and expressed optimism that improved collection and prosperity will reduce visible pollution.

Implementation Status of Jal Jeevan Mission

Since August 2019 the Government has implemented Jal Jeevan Mission to provide assured potable water through household tap connections in rural India. At the start of the mission only 32.3 million (mn) rural households, representing 16.7 per cent, were reported to have tap water connections. States and union territories have reported that 125.8 mn additional rural households have since been provided with tap connections. As a result, of about 193.6 mn rural households roughly 158.2 mn, or 81.71 per cent, are reported to have tap water supply at home.\n\nThe State, district and village level st..

Jal Jeevan Mission Reaches Eighty One Per Cent Rural Coverage

The Government reported substantial progress under the Jal Jeevan Mission, launched in August 2019 to provide tap water to every rural household. At launch only 32.3 million (mn) rural households had tap connections and states and Union territories reported provision of 125.8 mn additional households by March 2026. Consequently, out of about 193.6 mn rural households around 158.2 mn, or 81.71 per cent, are reported to have tap water at home. The Finance Minister announced extension of the mission until 2028 in the 2025-26 budget speech. The Swachh Bharat Mission Grameen, launched in October 20..

Empowering Local Governance for Sustainable Rural Water Supply

The Ministry of Jal Shakti has aligned the Jal Jeevan Mission (JJM) with the 73rd Amendment to strengthen village level planning and community ownership of water supply. Gram Panchayats, village water and sanitation committees and Pani Samitis are to plan, implement, manage and maintain piped water systems, with gram sabha processes formalising handover and oversight. Implementation support agencies including non government organisations, community based organisations and self help groups have been empanelled to train local committees and promote women participation. Under JJM, the department ..
