    Composting 101: Turn Kitchen Scraps into Garden Gold

    Roughly a third of everything the average household throws away is organic matter that could have become free, rich fertiliser. Composting is the rare eco habit that rewards you directly: less bin smell, fewer collection bags, and dark crumbly compost your plants will love.

    The only recipe you need: greens plus browns

    Compost is made by billions of microbes, and like any workforce they need a balanced diet. Greens are fresh, nitrogen-rich materials; browns are dry, carbon-rich ones. Aim for roughly two to three parts browns to one part greens by volume.

    • Greens: vegetable peelings, fruit scraps, coffee grounds, fresh grass clippings, old cut flowers.
    • Browns: dry leaves, torn cardboard, egg boxes, shredded paper, small twigs, straw.
    • Keep out: cooked food, meat, dairy, and oily leftovers in an open garden bin — they attract pests. (Sealed hot composters and bokashi systems can handle them.)

    A month-by-month rhythm

    Add material as it arises, covering each caddy of scraps with a layer of browns. Once a fortnight, turn the pile with a fork to let air in; oxygen is what keeps the process sweet-smelling. If the pile looks soggy, add cardboard. If it looks dusty and inactive, add greens and a splash of water. In warm months you can have usable compost in three to four months; a neglected pile still gets there in about a year.

    No garden? You still have options

    A sealed bokashi bucket ferments all food waste, including cooked leftovers, under the sink. A wormery fits on a balcony and produces both compost and a potent liquid feed. Many councils also collect food waste for industrial composting, which is a fine fallback.

    Finished compost is the perfect head start for a wildlife-friendly plot — see our guide to native plant gardening to put it to work. And to shrink the packaging side of your bin as well, browse our ten plastic-free kitchen swaps.

    10 Simple Swaps for a Plastic-Free Kitchen

    The kitchen is where most households generate the bulk of their single-use plastic: cling film, produce bags, bottled cleaners, and packaging from the weekly shop. The good news is that you do not need to overhaul your life in a weekend. Swapping one item at a time, as things run out, is cheaper, less stressful, and far more likely to stick.

    Start with the swaps that pay for themselves

    • Beeswax wraps instead of cling film. They mould around bowls and cut fruit with the warmth of your hands, wash clean in cool water, and last about a year before they can be composted.
    • Glass jars instead of plastic tubs. Rescue pasta-sauce jars for dry goods, leftovers, and freezer storage. They are free, airtight, and you can see what is inside.
    • Loose-leaf tea or plastic-free tea bags. Many mainstream tea bags are sealed with polypropylene. A small infuser removes the problem entirely.
    • Bar dish soap instead of bottled washing-up liquid. A solid block lasts months and works with a wooden brush just as well as liquid.
    • Cloth produce bags. Keep a few in your shopping tote so thin film bags never come home with you in the first place.

    Five more swaps once the basics feel easy

    • Compostable sponges and loofahs in place of plastic scourers that shed microplastics into the drain.
    • Refill-store staples. Rice, oats, lentils, and washing powder are the easiest products to buy by weight into your own containers.
    • A metal safety razor of a milk-frother-style spare part culture: choose kitchen tools with replaceable parts instead of throwaway gadgets.
    • Concentrated cleaner tablets that dissolve in a reusable spray bottle, replacing a new plastic bottle with a thumb-sized tablet.
    • Freezing in jars or steel tins instead of freezer bags. Leave headroom for expansion and label with a wax pencil.

    Make it stick

    Perfection is not the goal; direction is. Audit your bin for one week, note the three plastic items that appear most often, and target those first. Most families find that five swaps eliminate more than half their kitchen plastic.

    Once your kitchen habits are humming, the natural next step is dealing with food scraps. Our guide to composting kitchen scraps into garden gold shows you how to close the loop, and if you want to green your utilities too, see how home solar panels work.
