Waste Management

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…

“One life-form turns into another. Recycling is like that,”  says Ramnikbhai Satra, a scrap dealer, as he compares inanimate objects taking on another form to the cycle of death and rebirth. Even as he speaks to me, he keeps an eye on one of his workers weighing newspapers and flattened cartons, answers a customer who wants to know the price of some plastic objects kept in a tray next to which there is a box of glass jars of all shapes and sizes. “Individuals sell this stuff to me. Then it is picked up for recycling by different people— a…

You go to a pathologist to run some tests. Your blood is drawn out with a syringe, pressed down with a piece of cotton, and a tape is stuck on it. The needle, the syringe, and the cotton are biomedical waste and need special handling for its disposal. In the second part of our series on solid waste management in Mumbai, we look at specialised waste—waste generated in restaurants, e-waste and biomedical waste. Previously, in the first part we looked at how household waste is disposed and explored various agencies of the Brihanmumbai Municipal Corporation (BMC) that handle waste. Waste…

I take a delivery of vegetables, remove the vegetables from the plastic bag, and the plastic wrapping. The bag and the wrapping go into the bin, followed a while later with the peels and discarded bits of vegetables. The bin seems forever ready to take in whatever I throw into it: medicine wrappers, sanitary waste, paper, old batteries and so on.  While researching for this series of articles I realised both the quantum and variety of things that we, a household of four, end up throwing in the bin every day, and quite thoughtlessly so. The results: one full bin…

Are you aware of the nuances of the waste cycle of everyday items you discard, like a tissue or a soft drink bottle? Would you want to know more about this complex network of collection, sorting, and the final disposal at a recycling centre or landfill? Have you wanted to address the broken system of are our urban waste management processes? Would you like to innovate for better waste management?  Join our online workshop to gain an in-depth understanding of the journey of waste and innovate solutions to tackle the complexities of waste management. Goal of the learning session: To…

The Greater Chennai Corporation (GCC) implemented the Solid Waste Management Rules in 2016. The following year, it passed directions for bulk waste generators (including apartment complexes and gated communities) in Chennai to process their waste inside their premises. "Seven years down the line, very few bulk waste generators in Chennai are following the norms," points out P Natarajan, Founder of Namma Ooru Foundation in our earlier article. KGEYES Homes in Chennai's Besant Nagar is a 25-year-old residential complex with 36 dwelling units. Similar to many other apartment complexes in the neighbourhood, residents here did not adhere to the waste management…

Chennai generates as much as 6,300 metric tonnes of garbage every day. Of this, 60% of the waste is biodegradable — which means that if we segregate the waste properly at source this 60% could be prevented from going to the landfills and eventually turning into legacy waste. Like any other metro city, Chennai also faces many challenges in the management of solid waste. The first part of this series delved into the challenges that Chennai faces in segregating waste at source. In the second part, Dr J Radhakrishnan, Greater Chennai Corporation Commissioner, talks to Citizen Matters about various issues…

Vasanthi Kannan resides in a Kodambakkam apartment complex with eight units. She has spent nearly three decades as a civic activist, tirelessly advocating for household waste segregation. Despite her efforts, she remains the sole resident in her building, who segregates waste, before handing it over to the sanitation workers. In Pulianthope, a locality with 2,000 households, adherence was the issue. "The government distributed two bins to every household in 2020 and asked the residents to segregate the waste before handing it to sanitation workers. Initially, there was some compliance, but without strict enforcement, the initiative failed," says Selavaraj M, Founder…
