A large variety of things can be composted. Basically, if a thing can be decomposed (with a few practical exceptions) within a reasonable period of time, then they can be composted.
A Few Guidelines To Help The Process
- smaller is better: this is true of most things relating to compost. So, chop, shred, and/or tear items into small pieces to expedite debt decomposition and the mixing of the compost heap materials.
- mixing is good: too much density of any one material will slow the decomposition process, causing stratification, and make the mixing of the compost heap more difficult.
- know what is done enough: Some consideration should be given to how you intend to use the compost and what is considered done enough for use. Some slowly decomposing items may only need to be aged and/or partially decomposed to be useful in the garden. For example, wood shavings can add value to the humus of the soil or as a pathway materials after only a little aging, if everything else in the compost has completely decomposed.
- have multiple heaps: having at least two compost heaps and/or bins (even if small) is strongly recommended. So, you may have a heap for current use, while your old heap is finishing.
Compostable Household Items
Here are a few household items which can be composted:
- office paper (shredded)
- old newspapers (non-glossy)
- Wood ash (cooled and out)
- cardboard (non-glossy or coated)
- paper towels (including center cardboard tube)
- paper bags (shredded)
- egg cartons (made of uncoated paper or cardboard)
- Eggshells (crushed)
- kitchen fruit and vegetable scraps
- teabags and coffee grounds (including paper filters)
- old houseplants and potting soil (if not diseased)
Compostable Yard And Barn Items
Many yard and barn wastes can be composted. A few, which come to mind are:
- grass cutting (not treated with herbicide)
- autumn leaves (best if mixed with other materials, especially, animal manures)
- old straw and hay (broken up into small sections)
- livestock manure (chicken, rabbit, cow, horse)
- sawdust and wood shavings (smaller pieces are better)
- tree and brush waste (chopped small)
- old lumber (free of nails and paint; chopped small)
Items to Exclude From The Compost Heap
Certain items need to be excluded from the compost heap to ensure proper compost culture, avoid unwanted orders, avoid attracting unwanted pests and/or to keep the compost from being detrimental to the soil culture.
- plastic, metal, and/or glass items
- waste chemicals and paints
- Cat litter
- dog waste
- disposable diapers and wipes
- glossy magazines
- glossy newspapers
- glossy or plastic-coated cardboard boxes
- cooking and other oils and greases
- cook foods containing meat and/or heavy oils
