Composting turns kitchen scraps and garden waste into a rich soil improver. It also keeps organic waste out of landfill.

Many people give up because their compost becomes smelly or slimy. Both problems are easy to fix.

Greens and browns

Greens are nitrogen-rich, wet materials such as fruit and vegetable scraps, coffee grounds, and grass clippings. Browns are carbon-rich, dry materials such as cardboard, paper, dry leaves, and straw. Aim for roughly equal volumes, or a little more brown than green.

What not to compost at home

Meat, fish, and dairy, which can attract pests
Cooked food with oil or sauces
Pet waste from cats and dogs
Diseased plants and persistent weeds with seeds

Fixing common problems

Smelly, wet compost has too many greens; add shredded cardboard or dry leaves and turn it. Dry compost that is not breaking down needs more greens and some water. A pile that never heats up may be too small or need turning to add air.

No garden?

Small-space options include worm bins and bokashi bins, which ferment food waste indoors. Many cities also offer kerbside food-waste collection or community compost schemes.

Using the finished compost

Compost is ready when it is dark, crumbly, and smells earthy, usually after six months to a year. Spread it on beds as a mulch or mix it into potting soil.

This is general sustainability information. Recycling, composting, and disposal rules vary by municipality — check local guidance. Cost and energy savings are estimates and depend on your home and usage.
