Properly dispose of compostable waste like food and organic materials to reduce landfill greenhouse gases. If you have a garden, set up a compost heap or bin. Without a garden, use a small indoor composter with worms, organic matter, or electrical components. Choose ‘home compostable’ over ‘biodegradable’ items, such as compostable sponges. Ask a neighbour or local allotment to take your food waste for composting.
