Waste Management

It would be an understatement to say that humans are dependent on their electronic gadgets or devices. In this day and age of work from home and e-learning, where the pandemic has ensured that individuals and families spend most of their time within the four walls of their homes, it is safe to say that we’re all hooked on to some or the other electronic appliance, one way or the other. However, the question remains as to what happens to these electronic or electrical devices once their shelf lives are over? That is, when they have been reduced to 'e-waste'?…

A few years ago, if you were to drive off the airport road towards Bettahalasur, 30 km away from Bengaluru, you would find mounds of garbage littered around. The village did not have a functioning system of waste management. Littering was common practice and waste management was practically unknown. Garbage from approximately 2500 households, totalling about 53 tonnes per month, was dumped or burnt in the panchayat, causing air, water and soil pollution.

Translated by Sandhya Raju கீழ்பாக்கத்தில் தனது குடும்பத்துடன் வசிக்கும்78 வயது டி சுரேஷ், 2012-ம் ஆண்டு முதல் இது வரை ஆண்டுக்கு 2 எல்பிஜி சிலிண்டர் மட்டுமே வாங்கியிருக்கிறார். தினமும் அவர் குடும்பம் வெளியே சாப்பிடுவதில்லை, எலெக்ட்ரிக் அல்லது இண்டக்ஷன் அடுப்பையும் உபயோகிப்பதில்லை. "இதில் ஒன்றும் பெரிய சூட்சமம் இல்லை," என கூறும் சுரேஷ், கடந்த 9 ஆண்டுகளாக சமையலறை கழிவுகளிலிருந்து அவர்களுக்கான சமையல் எரிவாயுவை தயாரிக்கிறார். இது எந்தவொரு ஆய்வகத்தில் தயாரிக்கப்படுவதில்லை, தன் சொந்த வீட்டிலேயே அவர் நிறுவியுள்ள உயிர்வாயு அமைப்பு மூலம் பெறுகிறார். சமையல் எரிவாயுவை உருவாக்குவதைத் தவிர, உயிர்வாயு வெளியிடும் மிச்சம் தாவரங்களுக்கு கரிம உரமாக பயன்படுத்தலாம். பல வருடங்களாக மேற்கூரை சோலார் பேனல் வைத்திருக்கும் இவரிடம் பலர் இது குறித்து ஆலோசனை கேட்டுச் செல்கின்றனர். "சுமார் 10 வருடங்கள் முன், என்னுடைய சோலர் நிறுவலை கஆண வந்த ஒருவர், தான் உயிர்வாயு வணிகம் செய்வதாக…

Bengaluru’s water supply is met either by pipelines that draw water from the Cauvery river several kilometers away, or by pipelines that are sunk several feet underground. It wasn’t always like this. In the past, Bengaluru’s water needs were quenched by the many lakes built across the city. Lake water was used for drinking, agriculture, washing cattle and other purposes. But in recent years, the city’s lakes have become infamous for catching fire, frothing, and becoming dump sites. Many lakes are heavily polluted as the city’s sewage, industrial contaminants and untreated wastewater enter them via stormwater drains, rendering them unusable.…

Disposing of pet poop/pet waste is one of the most sensitive issues in a neighbourhood or apartment community, and there has been an increasing pressure on pet parents to be responsible by picking up after their pet. While one of the easiest solutions to dispose of pet waste is by bagging it, imagine the amount of plastic (fossil-fuel-based or plant-based) tied with dog poop that will be sent to landfills or incinerators.  An internet search around disposing pet waste throws up multiple options:  Bag it and disposeScoop and flush itScoop and trash near plantsScoop and bury, which basically promotes composting Let's…

78-year-old D Suresh lives with his wife, son and daughter-in-law in Kilpauk, and he says he has bought only two LPG cylinders per year since 2012. His family does not eat outside every day, nor do they use electric or induction stoves for cooking their daily meals. "It is not rocket science," says the septuagenarian when he says that he has been generating his own cooking gas from kitchen waste for over nine years. When the waste decomposes in the absence of oxygen, Suresh gets biogas that he uses for cooking. This process does not happen in a scientific laboratory…

As one takes a left turn from the East Coast Road or the ECR, as it’s popularly known in Chennai, into the Kuppam road in Kottivakkam, which leads to the Kottivakkam beach, a sense of calm sets in. A complete contrast from the bustling main road, which is just a few metres away. This sense of calm can also be seen in the residents of the Kottivakkam kuppam (Tamil for hamlet), most of whom you will find unwinding on a weekday evening. The women folk, after having finished their day’s work of selling fish are huddled in one corner of…

“In order to do something beautiful for the future, you need to go back to the roots,” said a beaming Supriya Sahu, IAS and Additional Chief Secretary of Environment, Climate Change and Forests, Government of Tamil Nadu, as she spoke of the Meendum Manjapai Vizhipunarvu Iyakkam (Back To Yellow Cloth Bags) campaign of the state government.

"My youngest son was born here (near the landfill) and while I was pregnant, I had to rely on the water from the handpump”, says Anita*, a waste picker living in Shraddhanand Colony adjoining the Bhalswa Landfill in Northwest Delhi.  If you’ve traveled by road to Chandigarh, you would have seen this is the mountain of trash. “He's had kidney problems ever since he was born,” adds Anita. “Within 5.5 years, we have had to get him operated six times! Because of the medical expenses, we have to go without ration for a few days. Stomach, skin, and eye problems…

Imagine you’re about to go to bed after a long and tiring day’s work. And at that very moment, you hear the dreaded sound of those heavy drilling machines from a house next to yours, as part of some work that looks likely to continue late into the night. Or imagine having to deal with the constant menace of dust pollution in your homes and locality because of some building activity in the neighbourhood. Perhaps not so difficult to imagine, given that it is a common issue that residents of India’s metro cities, including Chennai, have been facing for years:…
