How South Asia’s cities can tackle the threat of plastic pollution

“Once a pleasant rainy day, nowadays becomes a nightmare as I can’t manage any transport to go to [the] office. … I have to choose either work from home or wade through knee- or waist-deep, filthy water-filled, dangerous roads with potholes and open manholes. … I often choose the first option.” — A female commuter in Dhaka. These words capture the lived reality of millions across South Asia’s rapidly growing cities. The problem is not the heavy rain in itself; it is issues with environmental management common across the region: Mismanaged waste, unprecedented plastic production and disposal, weak policies, fragile urban infrastructure, and lack of cross-border collaboration. Solid waste, especially plastic, clogs drainage systems. Even larger canals and storm drains cannot function when choked with trash. A few hours of monsoon downpour can bring entire cities to a standstill. Many neighborhoods in Dhaka, Chattogram, Kathmandu, Kolkata, and Karachi have been paralyzed by severe waterlogging. Heavy downpours have caused flash floods in Bangladesh, Nepal, India, Indonesia, and flood alerts in northeastern districts of Bangladesh. The plastic-waterlogging nexus in South Asia Bangladesh generates over 3,000 tons of plastic waste daily, 646 tons from Dhaka alone, yet has fewer than 300 recycling plants — mostly informal. Of the 87,000 tons of single-use plastic consumed annually in Dhaka, only about 37% is recycled, with the remaining 63% contributing to blocked drains, river pollution, and open dumps. The Bangladesh Waste Management Rules 2021 introduced Extended Producer Responsibility, or EPR, to hold producers accountable for the collection, reuse, recycling, and safe disposal of packaging, e-waste, batteries, and tires. However, the framework is still evolving, with comprehensive guidelines under development, limiting effective implementation. By comparison: • India generates around 26,000 tons of plastic waste per day, with over 2,000 registered recycling plants. The implementation of the country’s Plastic Waste Management Rules — 2016, amended 2022 — and EPR remains uneven, with enforcement varying by state and an informal sector dominating collection and sorting. • Nepal generates 637 tons of plastic waste daily. Every day, Kathmandu alone produces 58 tons of plastic waste. Only three small recyclers in Kathmandu Valley process 15–20% of this waste, leaving the rest to leak into rivers, landfills, or open spaces. • Pakistan produces around 8,219 tons of plastic waste every day, yet only about 4% is recycled — the rest, if piled up daily, would form a tower twice as high as mount K2, 8,611 meters tall. Additionally, nearly 86% of plastic waste is mismanaged, contributing to environmental degradation and placing Pakistan among the top 10 plastic-polluting countries globally. Provincial laws and enforcement vary considerably. These figures reveal a shared regional challenge: Despite progressive policies, the gap between plastic generation and effective recycling remains vast. To address this, donors and regional bodies such as the South Asia Co-operative Environment Programme, the World Bank, and UNDP are supporting harmonized diagnostics and pilot projects because river-borne plastics require upstream–downstream cooperation. Strengthening national reforms through regional collaboration, harmonized monitoring, joint river cleanups, and aligned EPR systems will be essential to sustainably stop plastic from entering drains and rivers. Learning from regional and global examples South Asia can draw lessons from countries that have turned policy into practice: • Kenya enforced one of the world’s strictest bans on single-use plastic bags in 2017, drastically reducing clogged drains. • Rwanda, dubbed Africa’s cleanest nation, combines bans with strong enforcement and community awareness campaigns. • India piloted household-level waste segregation in cities such as Indore, now recognized as the cleanest city in the country. • South Korea has a highly regulated recycling system where 98% of food waste is recycled to compost, animal feed, and even energy, and plastic recycling is efficient. These examples show that with political will, public awareness, and consistent enforcement, transformation is possible 6 strategic priorities for the region Bangladesh and its neighbors face fragmented governance. Responsibilities are scattered across ministries and agencies, weakening enforcement and coordination. Ministries or government bodies responsible for urban planning, waste management, and foreign affairs must work collaboratively to align policies, financing, and cross-sectoral action. Here are six priorities to tackle: 1. Reduce plastic at the source: Expand refill and reuse systems for everyday goods such as shampoo, cooking oil, and detergents. 2. Promote biodegradable alternatives: Leverage local industries, such as jute in Bangladesh, hemp in Nepal, or maize in India, to scale eco-friendly packaging. 3. Modernize recycling and upcycling: Invest in infrastructure and integrate informal waste workers into dignified circular economy roles. 4. Strengthen the 3Rs strategy: The Reduce, Reuse, Recycle motto must be widely shared, while ensuring household-level segregation, municipal support, and public education. 5. Install drainage nets: Simple, low-cost nets at drainage mouths, like in Kwinana, Australia, catch bottles, bags, and plastic before they reach rivers and oceans, preventing tons of pollution and protecting marine life. 6. Drive behavioral change: Normalize reuse, address stigma around refilling, and embed plastic literacy in schools. Transboundary cooperation Regional coordination is equally vital. Rivers carry plastics from upstream countries such as India, Nepal, and China, affecting downstream nations like Bangladesh. Strengthening cooperation through the South Asian Association for Regional Cooperation, the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation, and regional plastic pollution treaties is crucial. Such agreements can standardize data collection, regulate waste trade, and establish joint river-cleaning initiatives. Toward inclusive and circular solutions Global frameworks such as the UNEA Global Plastic Treaty offer a platform to advocate for upstream accountability while advancing domestic circular economy strategies. Plastic pollution is not just an environmental issue; it is a social justice issue. Waste workers, who form the backbone of recycling, remain excluded from formal systems, often working without protection or fair pay. A truly circular economy must place its livelihoods and dignity at its center. The monsoon waterlogging crisis reminds us that without systemic change in how we produce, use, and manage plastic, South Asian cities will continue to drown, not in rainfall, but in their own waste. By learning from one another, strengthening governance, and advancing circular economy solutions, the region can transform plastic from a menace into an opportunity, allowing the monsoon, long celebrated in folklore, literature, music, and agricultural traditions, to bring relief and inspiration rather than despair.
