Waste Management

Visitors to Mumbai are often surprised by the city's lax attitude towards household waste segregation. Despite being aware of the importance of segregating garbage at its source, many residents fail to practise it because of various reasons. Meanwhile, Mumbai's dumping grounds are overflowing, and the situation worsens every year. Proposed solutions like waste remediation and waste-to-energy plants come with their challenges.creative Achieving real, on-ground change depends significantly on behavioural shifts. Moreover, experts have repeatedly pointed out that source segregation and decentralised processing are crucial to addressing waste issues. Can targeted interventions help? One major issue of legacy waste in the…

Waste collectors and processors report a massive surge in packaging waste, especially plastic packaging, from e-commerce transactions since 2017. In our last article on the topic, a waste worker from Bengaluru put this at 10-15% of all the dry waste they receive. Under Extended Producer Responsibility (EPR) regulations, brand owners are supposed to be responsible for the life cycle of all the plastic they introduce into the market. Let us say an e-commerce company delivers a packet of potato chips to a consumer, after wrapping it in a compostable plastic bag. Then the chips brand would be responsible for its…

Anjana S, a Bengaluru-based software engineer, estimates that e-commerce companies deliver at her doorstep at least 15 times a month. “I place orders with companies like Flipkart 2-5 times a month. And grocery orders with quick delivery companies, like Zepto, 3-4 times a week,” she says. Which leaves her with considerable packaging material, often plastic, that she has to dispose of. Like many Bengalureans, Anjana works out of home and rarely frequents retail shops these days. The discounts offered by e-commerce companies are more attractive as well. “Some platforms also waive the delivery fee if I buy a monthly pass,”…

In October 2021 Prime Minister Narendra Modi had declared a plan to make Indian cities garbage-free under Swachh Bharat Mission-Urban 2.0,  with the Government of India allocating Rs. 3,400 crore to Maharashtra for the implementation of the  Swachh Bharat Mission. According to the Environment Status Report (ESR) for 2022-23, released by the Brihanmumbai Municipal Corporation, Mumbai generated 6330 metric tonnes (MT) of waste per day in 2022. With the two dumping sites in Mumbai — Deonar and Kanjurmarg — overflowing, a radical change in our approach to solid waste management is urgently needed. As Maharashtra gets ready to go to…

“Namma ooru, semma joru…” – the catchy song playing from garbage collection vehicles every morning is a familiar sound for most Chennai residents. The Greater Chennai Corporation (GCC) anthem is a reminder to take out the garbage, as the conservancy workers do their rounds in battery-operated vehicles (BOVs) collecting waste door-to-door.  Some residents diligently segregate the waste into dry, organic and reject categories before handing it over to conservancy workers. Others just get rid of the mixed waste without a thought about where it will go and what would be its environmental impact. And the cycle repeats every morning. Ever…

Leftover rotis or rice, a half-eaten sandwich or the crust of the pizza, a forgotten piece of cake or stale cheese, from wilted spinach to expired milk or pickles, excess sambhar delivered with the breakfast ordered, extra food left over after a party,  an ugly looking tomato or a blemished vegetable or fruit, an extremely salty chutney or simply, a recipe gone wrong — all such perished food or leftovers often find their way to the bin, creating a huge amount of food waste from households.   But what’s the big deal in that, one may wonder.  Why food waste matters…

Bengaluru generates about 6,000 tonnes of solid waste everyday. As the city has grown, so have the challenges of solid waste management (SWM). As per this report from The New Indian Express, the city has seven landfills and six waste-processing units, which have not been upgraded for close to a decade now. With no BBMP elections since 2020 and general attitude of the people that their garbage ought to be someone else's problem, SWM has hit a black spot. Administrative flip flops In 2023, the BBMP floated 89 tenders for the collection and transportation (C&T) of municipal solid waste from…

As the dump trucks drive in and deposit tonnes of refuse at the dumping ground in Kodangaiyur, a group of people wait patiently to sift through the garbage. As far as the eyes can see, there are mountains of unsegregated waste and the stench is unbearable. This group of informal workers are the waste pickers of Chennai, an important cog in the wheel of waste management in the city. Chennai produces about 6,300 tonnes of waste daily, overwhelming the city’s two main dumping sites, Kodangaiyur and Perungudi, with unsegregated trash. Although some community-led initiatives raise awareness about the importance of…

Much of the waste we produce need not go straight to the landfill. With proper management, plastic crisp packets are recycled and repurposed, while banana peels and eggshells become soil. Hygiene waste items, such as used menstrual products, however, are destined for the dump or incinerator. This represents a significant environmental challenge. That's where concerted community efforts can make a big difference. A group in Kannamangala transformed their waste management practices through the support of Stone Soup, an organisation based in Bengaluru. Founded by Malini Parmar, Stone Soup is dedicated to sustainable waste management and menstrual hygiene initiatives, and it…

Trash is mostly an afterthought when it gets taken away seamlessly. Like most residents, I follow the weekly trash routine without much thought. This system contrasts with my recent experiences in Chennai, where household waste segregation is more community-oriented, while civic authorities are largely responsible for collection and disposal of the waste in the city.  Compared to Chennai, Seattle has a smaller population, about 762,500. Chennai's population according to latest GCC data is about 7.1 million. In both Seattle and Chennai, the city government contracts with private companies to collect waste, and charges households a collection fee. In Seattle, unlike…
