What Not to Compost, According To Vermiculturists

Everyone should do their own composting. It’s so easy to learn to compost, all you need is a composting bin or even just a composting toilet to get started.

Composting helps you cut down on household waste, which is good for the planet, and feeds the crops you grow for free!

However, that doesn’t mean that you can just throw everything in your home into the composting bin – you also need to know what not to compost and why.

10 Things That You Should Never Compost And Why

  1. Meat (including fish and bones): Composting these things will make your compost stink and it might kill the worms that make the compost too and it might also attract vermin to your home.
  2. Dairy (this includes eggs): If you think meat smells bad in compost, try some dairy, instead, it’s absolutely foul and it will attract pests. 
  3. Cooking oil (including any animal fats, butter, grease, etc. too): Oil won’t mix with the water in your compost and it will interrupt the composting process itself and while it won’t stink to high heaven, it will attract vermin. 
  4. Anything fat based: This is pretty much for the same reason as for cooking oil, fats just don’t mix with the water in your compost.
  5. Citrus fruit peels: They take absolutely forever to break down in a composting bin and worse, they’re quite acidic and they can kill off any worms you have and disrupt the overall composting process.
  6. Onions or garlic: While these things may be very good for our health, they’re toxic to worms and are capable of killing bacteria in the soil, breaking down your compost too. The good news is that you can plant them in the soil, instead, and they’ll grow new, fresh bulbs.
  7. Coffee pods and tea bags: Both of these things are made of plastic and won’t compost properly and may permanently contaminate compost that they are added to. 
  8. Biodegradable packaging: Unless it’s been certified fit for compositing, it probably isn’t and it needs to be sent to a recycling facility to be properly composted.
  9. Coated cardboard packaging: Anything with wax or plastic coatings isn’t suitable for composting – watch out for milk cartons, cookie packets, etc. 
  10. Baked products and grains which have been cooked: These items, and in particular cooked rice, can encourage toxic bacteria to breed in your compost and that can kill your crop when you apply the compost. Avoid.
