Composting waste from your kitchen is a great way to make nutritious organic soil for your garden plants while preventing useful material from taking up landfill space. If you keep a small composting bin in your kitchen, it will save you taking your waste out to the compost heap several times a day. Contrary to popular belief, an indoor bin doesn't smell bad when it's emptied regularly. Commercial compost bins are available, but you can build your own quite cheaply.
Get a large plastic bucket with a lid that snaps on. The bucket can be between 2 and 5 gallons, though it shouldn't be much bigger or it will take too long to fill. You can buy a paint bucket from a hardware store, or ask a restaurant for an empty food bucket.
Drill 12 to 15 holes in the lid of the bucket. The holes should be at least ¼ inch in diameter, with a ½ inch of space between them.
Glue the green scouring pads to the inside of the lid so that they cover all the holes. This type of pad is thin enough that it will allow air into the bucket while keeping flies out. There needs to be air in the kitchen waste or it will start to smell very quickly as anaerobic bacteria start to build up.
Place the bucket under the sink or in some other accessible place, and fill it with kitchen waste like vegetable and fruit scraps, used teabags and coffee filters, bread and cereal wastes and eggshells. Avoid putting meat products, dairy products or oily foods into the compost bin because these will attract vermin when placed in the compost heap outdoors.
Put other kitchen trash like egg containers, paper towels,and cardboard tubes into the kitchen compost bin. This will help aerate the compost and adds carbon into the mix.
Keep the bucket closed and sealed when you're not using it. If the lid is off, the compost will attract flies and curious house pets.
Empty the bin as soon as it becomes full, or about every 5 days. Rinse out the bin before bringing it back into the kitchen. Lining the bin with newspaper makes it easier to keep clean, and newspaper can be added to the compost.
