Composting turns kitchen scraps into something useful instead of sending them to landfill. It works in gardens, on balconies, and in small kitchens with the right setup — and the usual complaints, smell or slowness, have clear fixes.
The case for keeping scraps
Food waste in landfill breaks down without oxygen and produces methane, a potent greenhouse gas. Composted at home, the same scraps break down aerobically and become a soil improver instead. You also cut the weight and smell of your general waste, which matters if your council collects fortnightly.
Even a small amount of composting reduces what leaves your home. You do not need a big garden to make it worthwhile — a single countertop crock feeding one outdoor bin keeps a surprising share of your kitchen waste out of the general collection.
Compost is a balance of green material — nitrogen-rich and wet — and brown material, which is carbon-rich and dry. Get the ratio roughly right and the bin does the rest of the work.
The rough guide is more browns than greens by volume. If your bin smells, you need more browns. If it is dry and doing nothing, you need more greens or a splash of water.
Nitrogen-rich, wet
Vegetable peelings, fruit scraps, coffee grounds and filters, loose tea leaves, fresh grass clippings, and soft plant trimmings from the garden.
Carbon-rich, dry
Cardboard torn into palm-sized pieces, plain paper, dry autumn leaves, straw, and sawdust from untreated wood only — skip MDF, plywood and anything painted.
Setting it up
A dalek-style bin is enough for most households. Many councils sell subsidised compost bins, so it is worth checking your local authority before buying one at full price.
Work through these in order and the bin will be running within a couple of weeks. The steps are the same whether you have a whole garden or a paved yard.
Choose a spot on soil or paving, ideally in partial shade. Direct sun dries a bin out faster than you can keep up with in summer.
Start with a layer of browns at the bottom — a few handfuls of torn cardboard or dry leaves. This keeps the base draining instead of turning into sludge.
Add scraps in small batches and cover each one with a handful of browns. Burying food in the middle also keeps fruit flies down.
Turn the contents with a fork every few weeks to add air. Compost should feel like a wrung-out sponge — not soaking, not bone dry.
Keep a lidded container on the kitchen counter and empty it every few days rather than letting it build up and start to sour.
Most confusion around home composting comes down to one question: is this kitchen item safe for an open bin? These two lists are the working answer.
Yes, add it
Leave it out
If you want to compost cooked food, use a sealed bokashi system or a dedicated hot composter instead of an open heap.
Two systems work well indoors, and both fit under a sink or on a balcony. Pick based on whether you want to compost cooked leftovers or only raw vegetable scraps.
Sealed fermentation
A sealed bin plus a bran inoculant ferments food scraps, including cooked food and small amounts of meat. What you get out is not finished compost but a pre-compost that can be buried or added to an outdoor bin.
Liquid drains off during fermentation and can be diluted as plant feed, roughly one part liquid to a hundred parts water.
Worm-powered
Vermicomposting uses worms to process vegetable scraps into castings, a rich dark material you can mix into potting compost. Kept properly, it is low odour and quiet.
It is less suited to cooked food, oily scraps or citrus in bulk. Keep the bedding damp like a wrung-out sponge and feed in small amounts so the worms can keep pace.
Smells and flies
Smell usually means too much green material or too much moisture. Add browns, turn the bin, and check the base is draining.
Fruit flies
If fruit flies are a problem, bury food scraps in the middle of the pile rather than leaving them sitting on top. A lid that actually sits flat helps more than any trap.
A countertop crock with a carbon filter keeps the kitchen side quiet between empties.
Rodents
For rodents, avoid adding cooked food or meat to an open bin and keep the lid secure. A bin with a base plate or mesh underneath deters digging, and it also keeps the base cleaner.
Cold months
Cold weather slows the process but does not stop it. Keep adding material, add extra browns to absorb moisture, and do not expect much visible progress between December and February — the bin catches up in spring.
If you have space, keep a second bin going so you can leave one to finish while filling the other. Wrapping a bin with old carpet or a sheet of cardboard helps in hard frosts, but it is not essential and plenty of bins sit through winter uncovered.
Autumn
Keep layering. Fallen leaves are free browns — bag what you do not use for the winter months.
Winter
Expect little visible change and keep the bin draining. Do not flood it.
Spring
Turn the bin once and the pile finishes quickly as temperatures rise.
Closing the loop
Finished compost is dark, crumbly and smells earthy. It should not have recognisable food scraps in it. When a batch is ready, you have three straightforward uses for it.
Dig a few centimetres into beds and borders before planting, or spread it on the surface and let the worms take it down.
A layer around established plants holds moisture in summer and slowly feeds the soil underneath. Keep it clear of stems so they do not rot.
Sieve out any lumps and mix roughly one part compost to three parts potting compost for pots, window boxes and indoor plants.
A thin layer on lawns in spring works well too. It is gentle enough for most plants and adds the organic matter that helps soil hold water through a dry spell. If you are building a low waste home guide for your own household, once this loop is working you can move on to plastic free alternatives and other sustainable home essentials one change at a time.
Common questions
Three answers that resolve most of the hesitation around starting a bin. If your question is not here, ask us directly and we will point you at the right guide.
Only if the bag is plastic-free. Many standard teabags contain a small amount of plastic, so check the box, switch to loose leaf, or tear the bag and empty the leaves out before adding them.
Add more brown material like cardboard or dry leaves, and turn the contents to add air. Check the bin is draining — a bin sitting in water will always smell, no matter how many browns you add on top.
Not if you avoid cooked food, meat and dairy, and keep the lid secure. A base plate or mesh underneath helps, and it also keeps the base of the bin cleaner and draining better.
Keep the loop going
Composting works best as part of a wider zero waste living routine at home. Read the kitchen swaps guide for the plastic free alternatives that pair with a bin, or send us a question and we will answer it directly.
