The core composting do’s and don’ts are simple: add fruit and vegetable scraps, dry leaves and cardboard, but keep meat, dairy, oily food and pet waste out. Aim for roughly two to three parts dry “browns” for every one part wet “greens”, and keep the pile as damp as a wrung-out sponge. If you follow those three rules, most piles turn into dark, earthy compost in two to three months.
Key Takeaways
- Add: vegetable peels, fruit scraps, tea leaves, coffee grounds, crushed eggshells, dry leaves, shredded paper and cardboard.
- Avoid: meat, fish, bones, dairy, oily cooked food, pet droppings, diseased plants and glossy or coated paper.
- Ratio: two to three parts browns to one part greens, by volume.
- Moisture: damp like a wrung-out sponge, never dripping.
- Air: turn the pile every one to two weeks, so microbes get oxygen.
Why Composting Do’s and Don’ts Matter in India
Because wet kitchen waste makes up roughly half of what Indian households throw away, composting has a big impact. When it rots in a landfill, it produces methane, a potent greenhouse gas. Composting at home keeps that waste out of the bin, so it also cuts collection costs for your city.
The rules are tightening, too. India’s Solid Waste Management Rules, 2026, reportedly took effect on 1 April 2026 and require four-stream segregation at source. Therefore, wet waste must be kept separate from dry, sanitary and special-care waste. Bulk generators, such as housing societies, must also process wet waste on site or buy compliance certificates. Check the official notification from the Ministry of Environment, Forest and Climate Change for the exact wording that applies to you.
Good compost starts with the right ingredients, so the lists below matter more than any gadget.
What to Add: The Composting Do’s
First, compost microbes need two things: nitrogen and carbon. Greens supply nitrogen, while browns supply carbon. Fortunately, both groups are easy to find at home.
Greens: Wet, Nitrogen-Rich Materials
- Vegetable peels and trimmings
- Fruit scraps and rinds (in moderation for citrus)
- Used tea leaves and coffee grounds
- Fresh grass clippings and garden trimmings
- Crushed eggshells
- Stale roti, plain rice and bread in small amounts
Browns: Dry, Carbon-Rich Materials
- Dry leaves and twigs
- Shredded newspaper and plain cardboard
- Cocopeat and coconut husk
- Sawdust from untreated wood
- Straw and dry grass
Because browns keep air moving through the pile, they prevent clogging. Meanwhile, greens heat it up and feed the microbes. A pile with only greens turns slimy and smelly, whereas a pile with only browns barely decomposes.
| Material type | Examples | Role in the pile | Typical share (by volume) |
|---|---|---|---|
| Greens | Peels, scraps, tea leaves, fresh grass | Supply nitrogen and moisture | 1 part |
| Browns | Dry leaves, cardboard, cocopeat | Supply carbon and air space | 2–3 parts |
| Water | Sprinkled while layering | Keeps microbes active | Damp, not dripping |
What to Avoid: The Composting Don’ts
The second half of the composting do’s and don’ts is about what to keep out. Some items cause smell, pests or contamination. Consequently, experienced composters keep them out of a home pile.
| Avoid | Why it causes trouble | Better option |
|---|---|---|
| Meat, fish and bones | Rot slowly, smell strongly, attract rats and flies | Dispose through municipal wet waste collection |
| Dairy and cheese | Produces odour and draws pests | Same as above |
| Oily or heavily spiced cooked food | Coats other material and blocks air | Skip it, or use a certified community composter |
| Pet droppings | May carry pathogens that survive home piles | Municipal collection |
| Diseased plants | Pathogens can spread to your garden | Dry them in the sun, then bin them |
| Weeds with seeds | Seeds can survive and sprout later | Hot compost only, or bin them |
| Glossy paper and coated cardboard | Coatings and inks contaminate compost | Recycle with dry waste |
| Treated wood and coal ash | Chemicals and metals harm soil | Avoid completely |
However, be careful with “biodegradable” claims on bags and cutlery, because many are not home compostable. Our guide on whether compostable bags are actually compostable explains what labels to check.
Composting Do’s and Don’ts for Indian Kitchens
Quick checklist: composting do’s and don’ts
Indian cooking creates a few special cases, so here is how to handle the common ones.
- Onion and garlic peels: Add small amounts. Large quantities can slow worms and make the pile acidic.
- Citrus peels: Chop them finely and mix them with browns. Too much lemon or orange peel slows decomposition.
- Tea and coffee waste: Add freely. They are excellent greens.
- Cooked dal and rice: Add only tiny amounts, and bury them under browns. Otherwise, they attract flies and rodents.
- Neem and tulsi leaves: Add them in moderation. They decompose well when chopped.
- Coconut shells: Break them into small pieces first, or skip them because they take a long time to break down.
How to Build a Healthy Pile in Five Steps
- Choose a spot. Pick a shaded corner with good drainage. Direct sun dries the pile, while heavy rain soaks it.
- Lay a base. Spread a 3-inch layer of twigs or dry leaves, which lets air enter from below.
- Layer greens and browns. Add kitchen scraps, then cover them with dry material every time.
- Check moisture. Squeeze a handful. A few drops of water should appear, but no stream.
- Turn it. Mix the pile every one to two weeks with a fork or stick.
A well-balanced pile can reach 55–65°C in the centre. As a result, most pathogens and weed seeds die. The U.S. Environmental Protection Agency’s home composting guide describes the same principles of balance, moisture and aeration.
Common Composting Mistakes and Fixes
Most failures come from imbalance, but each problem has a quick fix.
| Problem | Likely cause | Quick fix |
|---|---|---|
| Bad smell | Too many greens or too little air | Add dry browns and turn the pile |
| Flies or maggots | Food scraps left on the surface | Bury scraps under browns, close the lid |
| Pile stays cold | Too dry, too small or too few greens | Add water and fresh greens, enlarge the pile |
| Ants | Pile is too dry | Sprinkle water and mix |
| Soggy and slimy | Too wet or compacted | Mix in shredded paper or cocopeat |
Also, if the pile refuses to warm up, read our troubleshooting guide on a compost pile that is not heating up. Not sure whether you need a bin or a machine? Compare both in compost machine vs compost bin.
How Long Does Composting Take?
A hot, well-managed pile finishes in about two to three months, whereas a passive pile that you rarely turn can take six months to a year. Finished compost looks dark and crumbly, smells like forest soil and shows no recognisable food scraps.
Warm weather speeds things up. As a result, many Indian households finish a batch faster in summer than in winter. Chopping material small and turning often also shorten the wait.
How to Use Finished Compost
For pots, mix one part compost with three parts potting soil. Then spread a one-inch layer around garden plants and water it in. Additionally, you can sieve the compost and return large pieces to the next batch.
Following the composting do’s and don’ts pays off here: compost improves soil structure and holds water longer. It also feeds plants slowly, so it reduces the need for chemical fertiliser.
Putting Composting Do’s and Don’ts Into Practice
Start small and keep a simple routine. First, collect kitchen scraps in a covered bin, and then add dry browns every time. Finally, check moisture weekly, because the composting do’s and don’ts come down to balance, air and the right ingredients.

Frequently Asked Questions
What should you never put in a compost bin?
Avoid meat, fish, bones, dairy, oily cooked food, pet droppings, diseased plants, glossy paper and treated wood, because these items smell, attract pests or add contaminants.
What is the correct ratio of greens to browns?
Use about one part greens to two or three parts browns by volume. This mix gives microbes enough nitrogen and carbon, and it keeps the pile airy and odour-free.
Can I compost cooked food at home?
Plain cooked vegetables, rice and bread are fine in small amounts if you bury them under browns. However, oily, spicy or meat-based food attracts pests and slows decomposition, so most beginners should skip it.
How often should I turn my compost?
Turn the pile every one to two weeks. Turning adds oxygen, so it speeds up decomposition and prevents bad smells.
Why does my compost smell bad?
A bad smell usually means too many wet greens or too little air. Add dry leaves, cardboard or cocopeat, then mix the pile well.
Are onion and citrus peels safe to compost?
Yes, but only in small amounts. Chop them finely and mix them with browns, because large quantities slow decomposition and can make the pile too acidic.
Do compost bins attract rats?
Bins attract rats mainly when they contain meat, dairy or exposed food scraps. Therefore, keep the lid closed, bury fresh scraps under browns and use a bin with a fine mesh base.
