What is the usual thing you do after your dinner? You scrape the leftovers in the bin, tie it up, and throw it out. Right? It is not only what you do but what millions of households do. But think of it this way, if one house of waste amounts this much, what will be the story of millions of houses? Have you ever put your mind behind where all this waste goes?
According to the Central Pollution Control Board, India generates over 62 million tonnes of municipal solid waste in one year. Did you know that nearly 50% of this is organic waste? But get this: Only 20% of total waste is actually processed, while the rest find its way straight into landfills, rivers, and streets.
This has been polluting our cities to the core. What if there was a way to reduce this waste right at the source, within our homes? That answer is composting, a simple, natural process that can provide valuable fertilizer from food scraps while drastically reducing the waste in their households.
Understanding home composting: what is it and how does it work? In essence, composting, simply put, is nature's way of recycling. Normally, organic waste like fruit peels, vegetable scraps, and garden waste gets decomposed into nutrient-rich compost that can be used to enrich the soil.
Composting types include:
Aerobic composting: This composting method, using oxygen, speeds up decomposition. Requires regular turning of the pile.
Anaerobic composting: Decomposes waste without oxygen. Anaerobic decomposition is slower and can result in unpleasant odors.
Vermicomposting: earthworms are used for breaking down organic waste, which turns into a high-quality compost within a short duration.
But why should you bother? Let’s explore its impact.
How Composting is the Solution
Every time we throw food scraps in the trash, they don’t just disappear—they pile up in landfills, where they decompose without oxygen, releasing methane, a greenhouse gas 25 times more potent than CO₂.
By composting:
Less waste goes to landfills, reducing harmful emissions.
Household waste volume decreases by 30-50%, making trash collection more efficient.
Food waste is put to good use instead of being a problem.
Case Study: Pune’s Decentralized Food Waste ManagementPune has pioneered a decentralized composting model where housing societies are encouraged to compost their own waste. This initiative has reduced the city’s organic waste by nearly 50% (SWaCH Pune, 2022).
Environmental Benefits of Composting
Still not convinced? Let’s look at the bigger picture.
1. Reducing carbon FootprintTransportation and landfill waste disposal contribute to air pollution. Composting cuts down the need for garbage trucks and landfill expansion.
2. Prevents Soil DegradationChemical fertilizers deplete soil nutrients over time. Compost enriches the soil naturally, improving fertility and water retention.
3. Helps in Climate Change MitigationBy reducing methane emissions, composting plays a role in combating global warming. In fact, compost-enriched soil stores more carbon, acting as a natural climate solution (FAO, 2022).
Economic & Practical Benefits for Households
Think composting is just good for the environment? It’s great for your wallet, too!
Saves money on fertilizers—your plants thrive on homemade compost.
Reduces waste collection costs—fewer trash pickups, lower municipal expenses.
Turns waste into a resource, making cities cleaner and more efficient.
Success Story: Bengaluru’s Composting DriveBengaluru generates 4,000 tonnes of waste per day, with nearly 60% being organic. The city’s composting and waste segregation initiatives have reduced landfill waste and improved urban cleanliness (BBMP, 2023).
Common Challenges & How to Overcome Them
Many people hesitate to compost due to concerns about smell, pests, or space. But these are easy to manage:
❌ Bad Odor?
Add more dry leaves and turn the pile for aeration.❌ Too Many Flies?
Avoid adding dairy, meat, or oily food.❌ No Space?
Use a small compost bin or try community composting.
Get Started with Home Composting
Ready to give it a try? Here’s a quick step-by-step guide:
Choose a composting method (aerobic, anaerobic, or vermicomposting).. Get a compost bin (can be DIY or store-bought).Layer your waste:
Green waste (wet waste): Vegetable peels, fruit scraps, coffee grounds.
Brown waste (dry waste): Paper, dry leaves, coconut husk.Turn the pile every few days to speed up decomposition.After 30-60 days, your compost is ready to use in plants or gardens!
Community and Large-Scale Composting Initiatives
For those living in apartments or cities with limited space, community composting is an excellent alternative. Several cities in India have set up public composting units where residents can contribute their organic waste.
Example: Indore’s Waste-to-Compost InitiativeIndore, ranked India’s cleanest city, has implemented large-scale composting that converts 550 tonnes of waste daily into compost, which is then used in parks and sold to farmers (MoHUA, 2023).
The Ending Note
Who has to face the increasing negative impacts of organic waste? It is we who generate it. But if we prevent it from the earliest, we can preserve a better world for our future generation.
Think of this way: If every household composted, India could reduce organic waste in landfills by half. That’s a massive difference!
So, why wait? Start today. Set up a compost bin, involve your family, and take charge of your waste. After all, a cleaner planet starts right at home.
The Future of Composting
With increasing government support, composting is becoming a mainstream food waste management practice. Policies like the Swachh Bharat Mission and local composting incentives encourage citizens to compost at home.
Innovations in composting technology—like automated compost bins and bio-digesters—are making the process even easier for urban homes.
