Home Compost: What Not to Add

Ever wonder why your balcony compost sometimes smells or attracts critters? Let’s clear up the common kitchen leftovers that belong in the bin and those that don’t.

What’s Safe to Compost

Orange peels and onion skins are fine, but meat, dairy, oily foods and pet poop can bring rats, maggots and germs that a small bucket never gets hot enough to kill.

What Not to Compost

A farm heap reaches 55 to 65 degrees, killing germs, but a 20-litre balcony bucket stays near room temperature. So the rule is simple: if it attracts rats, rots, or carries unwanted germs, keep it out. That means meat, fish, bones, dairy, and oily leftovers are a no-go. Cooked rice, roti or daal can be okay in tiny amounts buried deep, but larger piles will get mouldy and smelly.

Why These Are Bad

These are rich foods, and every neighborhood creature knows that. A chicken bone can lure a rat up two floors of pipe. Dahi and paneer turn sour and slimy long before they decompose. Oil is sneaky: a spoonful of leftover curry coats nearby peels, blocks air and creates a greasy lump that lingers for months. The fix is to avoid making those leftovers in the first place.

Pet Waste & Human Waste

Dog and cat droppings can carry roundworm eggs, and cats may spread toxoplasma, which is a concern especially during pregnancy. Those parasites survive happily in a cool home bin and can end up in the pot where you grow herbs. Used cat litter falls into the same category, no matter what the pack says. Human waste, including diapers, belongs in a dedicated composting toilet, not a balcony bucket.

Sneaky No-List Items

Many tea bags hide a fine plastic mesh or a sealed plastic strip, so tear them open and compost only the leaves. Fruit stickers are plastic and will linger in your finished compost for years. Glossy or coloured paper, magazines, shiny gift wrap, printed cartons and paper cups, often claim to be compostable but are really meant for industrial hot piles, not a balcony bucket.

Citrus & Onion Myths

The worry that citrus and onion peels ruin compost comes from worm bins, where large amounts can upset the worms. In a regular kitchen bin, normal kitchen amounts break down just fine, just chop them and mix them in. Orange peel even has other uses before it reaches the bin, like zest or cleaning. Eggshells can be rinsed, dried and crushed before adding. Citrus should be cut into small pieces and kept to about a quarter of the batch. Onion and garlic skins are dry and papery, so they count as browns. Used tea leaves can be rinsed and added too.

When in Doubt

If you’re not sure, it’s safer to leave the item out, a slower bin beats a rat-infested one. Pregnant people should wear gloves and wash hands with soap after handling compost. Keep toddlers and pets away from the bin, and never use pet droppings for food-growing pots. If a child eats compost, rinse the mouth and call a doctor if they vomit, have a fever, or seem unwell.
