Every time you throw vegetable peels, fruit scraps, and tea leaves in the dustbin, two things happen simultaneously: you pay for garden fertiliser you don't need to pay for, and you add to India's mounting landfill crisis.

India generates 62 million tonnes of solid waste annually. Approximately 60% of that is organic waste — kitchen and food scraps that could be composted. Instead, this waste goes to landfills where it decomposes anaerobically (without oxygen), producing methane — a greenhouse gas 80 times more potent than CO₂ over a 20-year period.

Home composting solves both problems at once: it diverts waste from landfills and gives you rich, free fertiliser for your plants, terrace garden, or balcony pots. And in Indian conditions — warm temperatures, good sun, access to dry leaves — composting is easier and faster than in colder countries.

No Smell
A well-managed compost bin does not smell — the "smell" comes from improper management (wrong ratio of dry to wet material, or anaerobic conditions). All methods in this guide are odour-free when done correctly.
Composting science; aerobic vs anaerobic decomposition

The Two-Material Rule — Everything You Need to Know

Composting is simply the process of aerobic (with oxygen) decomposition of organic material by bacteria and fungi. All you need to understand to compost successfully:

Greens (Wet/Nitrogen-rich):


  • Vegetable and fruit peels

  • Cooked vegetables (without oil or salt, if possible)

  • Tea leaves, coffee grounds

  • Fresh garden leaves

  • Leftover dal, rice, roti (small amounts)

Browns (Dry/Carbon-rich):


  • Dry leaves (fallen from trees)

  • Shredded newspaper or cardboard (not glossy)

  • Dry coconut coir (coconut shell fibre)

  • Sawdust (from untreated wood)

  • Dry straw

The golden ratio: 1 part Greens to 2-3 parts Browns (by volume)

Most composting problems — smell, flies, slow decomposition — come from too many greens and too few browns. Keep a small bag of dry leaves next to your compost bin. Every time you add kitchen waste (greens), add two handfuls of dry leaves (browns).

Method 1: Pot Composting — For Apartments and Small Spaces

This method requires no garden — it works on a balcony, terrace, or even inside a kitchen.

What You Need

  • Two medium earthen pots (matka) or plastic containers (25-30 litre each) with drainage holes at the bottom
  • A piece of mesh/net to cover the top (prevents fruit flies; mesh net used for windows works)
  • Dry leaves or coir (easily available at plant nurseries)
  • A small bamboo stick or skewer to aerate

Cost: ₹300-600 for the pots; dry leaves are free.

Setup (10 Minutes)

  1. Make 5-8 drainage holes in the bottom of each pot (a nail and hammer work)
  2. Place a layer of soil (3-4 cm) at the bottom of one pot
  3. Your compost bin is ready to use

Daily Use (2 Minutes per Day)

  1. Collect kitchen waste in a small covered container during the day
  2. Once a day, add the kitchen waste to the pot (Greens)
  3. Immediately cover with 2-3 handfuls of dry leaves or coir (Browns)
  4. Once a week, stir the contents with the bamboo stick from top to bottom (this adds oxygen, the key driver of decomposition)
  5. The compost should feel moist, not wet. If it's too wet: add more dry leaves. If too dry: add a little water.

When Is It Ready?

After 3-4 weeks, when the pot is half-full, stop adding fresh material to Pot 1 and start filling Pot 2 using the same method. Leave Pot 1 to finish decomposing for 2-4 more weeks.

Finished compost looks like dark, crumbly soil. It smells earthy (like forest floor) — not unpleasant. When you can't recognise any original material and it feels like soft soil, it's ready.

Using Your Compost

  • Add 1-2 handfuls to each plant pot in your balcony garden as a top dressing
  • Mix 20-30% into potting mix for new plants
  • For terrace gardens: replace expensive fertiliser bags with your free compost
  • Give to neighbours, schools, or community gardens if you produce more than you need

Method 2: Pit Composting — For Houses With Land

If you have a garden or even a small yard, pit composting is the simplest and least effortful method.

Setup (30 Minutes, One Time)

Dig two pits, each approximately:


  • 1 metre wide × 1 metre long × 1 metre deep (adjust based on available space)

  • Place them near a tree or garden bed where the compost will be used

Daily Use

  1. Add kitchen waste to Pit 1 daily
  2. Cover each addition with a layer of dry leaves and a thin layer of soil
  3. The soil layer prevents flies and controls odour

The Two-Pit Cycle

After 3-4 months, Pit 1 is full. Stop adding material to it; start filling Pit 2. By the time Pit 2 is full (another 3-4 months), Pit 1 has fully composted.

Remove the finished compost from Pit 1 and use it in your garden. Then restart the cycle — Pit 1 becomes the new active pit.

No stirring required in pit composting — the depth and soil coverage handle the process naturally, though stirring once a month speeds things up.

Extra: Using Earthworms (Vermicomposting)

Adding red earthworms (available at agricultural stores or online for ₹200-500 per kg) to your pit or pot dramatically accelerates decomposition and produces vermicompost — richer in nutrients than regular compost.

Vermicompost is highly valued by farmers and gardeners and can be sold locally for ₹15-30 per kg if you produce more than you need.

Method 3: Bokashi Composting — For Cooked Food, Even Meat

Bokashi is a Japanese composting method that handles food types that don't work well in regular compost bins — cooked food, oily food, meat, fish, and dairy — in a completely odour-free way, even indoors.

What It Is

Bokashi uses beneficial bacteria (lactobacillus — the same bacteria in curd/yoghurt) pre-inoculated on wheat bran. These bacteria ferment (not decompose) the food waste in an airtight container, producing a pre-compost material that is buried in soil to complete decomposition.

What You Need

  • An airtight plastic container with a tap at the bottom (5-10 litres) — available online or at home composting stores for ₹500-1,500
  • Bokashi bran (wheat bran inoculated with beneficial bacteria) — available at organic stores and online for ₹200-500 per kg

You can make your own Bokashi bran: Mix 1kg wheat bran + 100ml cow dung (from a healthy cow) + 100ml curd + 1 tablespoon jaggery dissolved in 1 litre water. Mix, seal in a bag, ferment for 2-3 weeks in shade. Dry and use as bran.

Daily Use

  1. Add kitchen waste (any kind — cooked food, meat, fish — all accepted)
  2. Sprinkle a thin layer of Bokashi bran on top (1-2 tablespoons per cup of food waste)
  3. Press down firmly to remove air pockets
  4. Close the lid tightly

The container must remain airtight. Every 2-3 days, open the tap at the bottom and drain the "Bokashi liquid" — dilute 1:100 with water and use as liquid fertiliser for your plants.

After the Container is Full (2-3 Weeks)

Bury the Bokashi material in your garden soil or a large pot at 15-20cm depth. Cover with soil. In 2-3 weeks, it completely decomposes into rich soil amendment.

The buried material has a sour smell initially (from fermentation) — this dissipates within a week of burial.

Common Problems and Solutions

| Problem | Likely Cause | Solution |
|---|---|---|
| Smell like rotten eggs / ammonia | Too many greens (nitrogen); too little oxygen | Add more dry leaves; stir to aerate |
| Smell sweet/fruity (fruit flies) | Too many fruit scraps uncovered | Cover all greens immediately with browns; cover top with mesh |
| Compost too wet / slimy | Too much moisture; too little brown | Add large amount of dry leaves; stir |
| Nothing is decomposing | Too dry; too many browns | Add a little water; balance with more greens |
| Ants in the compost | Normal and actually helpful | Only a problem if biting; reduce moisture slightly |

Municipal Composting Support

Several Indian cities now support home composting initiatives:


  • Bengaluru: BBMP provides free composting bins to residents under the IKM waste management programme

  • Pune: PMC has composting incentive programmes with free materials

  • Mumbai: Several wards have composting collection drives and community compost yards

Check your municipality's website or call the local ward office to ask about home composting support programmes.

Action Steps — Start This Week

  1. Save dry leaves: Before you do anything else, start collecting dry leaves from under trees near your home. Keep a bag near the kitchen. This is the most important preparation step.
  1. Set up a kitchen collection container: A small covered pot or steel container with a lid beside the kitchen sink — all peels, scraps, and tea leaves go in here during the day.
  1. Start with pot composting if you have any outdoor space — buy two earthen pots (₹150-200 each), drill drainage holes, add a soil base, begin the next day.
  1. For cooked food waste: order Bokashi bran online and an airtight Bokashi bucket — this is the solution specifically for oily and cooked waste that most people generate daily.
