120 Things You Can Compost from Home

Composting is the perfect solution to household waste. Rather than everything going in the trash and ending up in a landfill somewhere, it is naturally broken down into powerful fertilizer that can then be used to help your plants, vegetables and flowers thrive.

120 Things You Can Compost from Home 1

We have broken our list down into sections covering different parts of your home. There are so many things that can be composted, but there are also a few things that you shouldn’t compost – so to help you out, we’ve also added a few notes note about which things to avoid.

Here’s our list:


Things Can Compost from Kitchen

The kitchen is where most of the contents of your compost pile will come from – almost everything organic can go in and will break down easily. For larger items, if you want to speed up the composting process, you should make sure you chop the items up before adding them.

Compost heaps need two types of material, “green” and “brown”. Green material is “wet” plant-based material like vegetable scraps while brown material is “dry” stuff like paper, cardboard and so on.

The key to successful composting is to have a good balance of both. Most of the stuff that comes from your kitchen will be green material – however, if your pile seems too moist or begins to smell bad, try adding more brown material from elsewhere in your house.

Here’s what can go onto your pile from the kitchen:

  1. Fruit – most fruit is fine but go easy on citrus, see below for more details
  2. Vegetables – vegetable leftovers will make up a large part of your pile
  3. Fruit and vegetable peels
  4. Inedible leaves and stalks from fruit or vegetables – ideal material for composting
  5. Potato peels – another classic ingredient to add to your compost pile
  6. Onions and garlic – but used in moderation and don’t put into worm composters at all
  7. Citrus peel – in moderation but not in worm composters
  8. Tea leaves
  9. Coffee grounds
  10. Teabags and coffee bags (only if 100% natural – no synthetics)
  11. Coffee filters (if 100% natural)
  12. Eggs shells, crushed (these are alkaline and help counteract anything acidic you add)
  13. Fish bones – crushed, but be sure there is no flesh left on or it will smell bad
  14. Seaweed, kelp and nori
  15. Cooked pasta – make sure you bury it deep in the pile or it will attract scavengers
  16. Cooked rice – bury it in the pile, the same as pasta (uncooked rice may attract rats)
  17. Tofu
  18. Tempeh
  19. Flour
  20. Nuts and nut shells (not walnuts or their shells – they are toxic to other plants)
  21. Avocado pits (chopped to speed up the process)
  22. Olive pits
  23. Juice from canned products
  24. Shellfish shells (including crab, shrimp, lobster etc. – but bury them to avoid odors)
  25. Old seeds (pumpkin, sunflower etc. – chopped to prevent them sprouting)
  26. Stale grains
  27. Stale cereal
  28. Old oatmeal
  29. Stale energy bars, cereal bars etc.
  30. Stale bread (buried to avoid attracting scavengers)
  31. Burnt toast (again, buried)
  32. Stale pita (buried)
  33. Stale tortillas (buried)
  34. Stale tortilla chips, stale potato chips
  35. Old or moldy pasta sauce or similar
  36. Stale crackers
  37. Stale cookies
  38. Stale pretzels
  39. Stale candy (chopped or crushed to speed up the process)
  40. Popcorn – popped, unpopped or burnt, all are ok
  41. Corn cobs (will take some time to compost, so chop them up to accelerate the process)
  42. Crumbs (from tables, the bottom of food packets or any that fall on the floor)
  43. Old cheese (not too much – buried to so you don’t attract scavengers)
  44. Yogurt (not too much – buried)
  45. Soy milk, rice milk, almond milk, coconut milk
  46. Old jam or preserves
  47. Stale beer
  48. Stale wine
  49. Old herbs and spices
  50. Pizza crusts
  51. Napkins
  52. Paper towels
  53. Paper towel rolls (chopped up to speed up decomposition)
  54. Paper table cloths (torn up to speed things up)
  55. Paper plates (but not ones with waxy or plastic covering)
  56. Paper bags (torn up)
  57. Cupcake or muffin cups (not if waxed)
  58. Cardboard egg cartons (chopped up)
  59. Pizza boxes, chopped up (not if waxed)
  60. Other cardboard boxes (but not if waxed or printed with colored ink)
  61. Toothpicks
  62. Chopsticks
  63. Wood or bamboo skewers
  64. Wine corks (chopped)

Things to avoid include…

Meat, fish, and dairy

From the kitchen, there are also a few things you should avoid. The main ones are meat and fish, both cooked and raw.

While these will technically break down into compost, they will smell bad as well as providing a breeding ground for harmful bacteria.

The strong odors also attract pests and scavengers, anything from rats to coyotes and bears, depending on where you live. For these reasons, they are best avoided.

Most paper and cardboard items are fine, but avoid anything with glossy or waxy coatings as this won’t break down and will contaminate your compost pile.

Also, citrus peel, onions, and garlic should only be composted in moderation. If you add too much, your compost pile will become too acidic and the beneficial microorganisms and worms that do the composting won’t be able to survive – although small amounts are fine.

However, if you have a worm composter, avoid adding citrus, onion, and garlic altogether.

One other item to avoid is cooking oil. This will alter the chemical balance of the compost pile, making it an unsuitable habitat for the creatures and microorganisms that you need for the composting process to work.


Things Can Compost from bathroom

There are quite a few items from the bathroom that can be added to a compost pile – the general rule is, anything organic can go in while anything inorganic (think plastic sticks on cotton buds) shouldn’t be added.

These are some common bathroom items that can be composted:

  1. Toilet roll tubes
  2. Facial Tissues
  3. Hair from hairbrushes
  4. Facial hair trimmings from electric shavers
  5. Old loofahs Sponge – 100% natural only, cut up
  6. Cotton balls – 100% cotton only

Things to avoid include…

Hygiene and sanitary products

Avoid any contaminated personal hygiene items such as used tampons or babies’ diapers. Although some people might say you can compost these items, they are soiled with human fluids and are not suitable for composting.


Things Can Compost from home office

As we already mentioned, every healthy compost pile needs a good balance of “green” and “brown” items. Brown items are things like cardboard or paper, and your home office is a great source for these kinds of things.

If your compost pile has too much green material from the kitchen, you can look to your office for a source of brown waste to balance out the green. Paper and carboard are important components to add – remember, they are also natural products that come from trees.

Just be careful about adding any kinds of paper or card with glossy coatings or anything that has been printed with colored ink.

Here are some things that can be added:

  1. Used paper (not printed, especially with colored ink)
  2. Envelopes (remove any plastic windows)
  3. Bills
  4. Pencil Shavings
  5. Business cards (but only plain card ones, not if they have a coating)
  6. Post-it notes
  7. Kids’ homework (when no longer needed!)
  8. ATM receipts
  9. The “holes” from a hole puncher

Things to avoid include…

newspaper and cardboard

Don’t compost envelopes with plastic windows – remove the plastic first. Glossy business cards will not break down properly, while colored inks may poison the worms and microorganisms that do all the composting work.

Laundry room

Things Can Compost laundry room

The laundry room can be a source of compostable items – the main thing to look out for is anything synthetic. While clothes made from 100% natural materials can be composted, anything synthetic shouldn’t be used.

  1. Old cotton clothing (100% natural only), cut into small pieces
  2. Old wool clothing (again, 100% natural only, cut up)
  3. Old jeans, cut up
  4. Old cotton towels and bedsheets (100% cotton only), cut up
  5. Dryer lint (from 100% natural clothing only, no synthetics)

Things to avoid include…

Avoid adding any clothes or other fabrics that are not 100% natural. Synthetic materials will not break down and will contaminate your compost pile.

Remember, an alternative to composting old clothes is giving them away to charity, and this might be a better solution than attempting to turn them into fertilizer for your garden.

Around the house

Things Can Compost around the house

There are lots of other miscellaneous items from around the house that are all suitable for composting – and many of them are things you might not immediately think of. As always, avoid anything non-organic, but any of the following is perfectly fine:

  1. Dead houseplants (but not if they were diseased when they died)
  2. Old soil from houseplants (not from diseased plants)
  3. Dead flowers
  4. Natural potpourri
  5. Newspapers – chop up for faster composting
  6. Papier mâché
  7. Contents of dustpan (minus anything non-organic)
  8. Ash from wood fires (but not coal fires)
  9. Sawdust – but only if you are certain it comes from 100% untreated wood
  10. Junk mail (remove plastic windows from envelopes, don’t use if glossy or colored)
  11. Dust bunnies
  12. Aquarium plants
  13. Old fish food
  14. Birdcage droppings
  15. Pet hair
  16. Bedding from non-meat-eating animals such as hamsters and rabbits, including soiled
  17. Cigar stubs
  18. Cigarette waste – but remove the filters first
  19. Christmas trees
  20. Old ticket stubs (like cinema tickets etc.)

Things to avoid include…

You should avoid anything non-organic. This includes items like soda cans or anything glass. These will not break down, and in the case of glass, may smash and end up spread over your garden, becoming a dangerous hazard for you, your kids or any pets.

Another one to avoid is any coal fire ashes. Unlike wood fire ashes, coal ash is high in sulfur and will make your compost pile toxic for worms and microorganisms.


Things Can Compost from yard

Along with your kitchen, your yard is the place that will probably provide the largest volume of material for your compost heap. Since most things are natural, there is very little that can’t go on your pile – in fact, it’s probably best just to remember the things you shouldn’t compost.

All of the following are excellent items for composting:

  1. Grass clippings
  2. Ash from wood fires
  3. Dead plants (not if diseased)
  4. Dead leaves
  5. Animal droppings – but not from meat-eating animals like cats or dogs
  6. Fallen bird nests
  7. Snail shells
  8. Feathers
  9. Acorns
  10. Pond muck
  11. Algae
  12. Straw
  13. Small twigs
  14. Larger branches – but must be cut up small first or they will take too long
  15. Bamboo
  16. Horse hair

Things to avoid include…

Dog poop

There are one or two things that should be avoided. For a start, cat or dog poop shouldn’t be composted. Since these animals are carnivores, their droppings may contain harmful bacteria as well as parasites, and you don’t want to spread these on your garden

This is especially important if you are using your compost to fertilize your vegetable garden or any other edible plants.

If you find any dead animals in your garden (or even family pets!), don’t be tempted to compost these either. They can spread disease and may also attract scavengers. Much better to bury or burn them.

Avoid trying to compost weeds since they may continue to grow or contaminate you pile with seeds. Another one to avoid is any diseased plants – if you try to compost these, you may end up spreading the disease around the rest of your garden.

Don’t add any types of synthetic fertilizers, pesticides or herbicides. These will upset the chemical balance in your compost pile and may kill all the microorganisms and worms that are essential to the composting process.

So much you can do to help your garden and the environment

Most people know that composting is a great way to help protect the environment while at the same time providing a steady source of free and potent fertilizer for the garden. However, what many people might not realize is just how much household waste can be composted.

Composting isn’t limited to just fruit and vegetable scraps from the kitchen, and as long as you remember the few items that shouldn’t be composted, you will be able to help your garden thrive all while doing your bit to help save the planet.
