Most ecologically aware persons have learned about the benefits of compost and are having fun turning some of the organic residue of their household into nutrient for their plants. However, there are some limitations to what you can compost and many are, with good reason, careful about what they add to their compost pile. However, you might be avoiding some of the things that would work very well as compost, so here are a few of the things you had no idea you could compost.

If you have pets, you might do your compost bin a favor and feed it some of the waste your pets leave behind, such as fur, claw clippings and pet food. Be careful about composting your pets’ fecal matter though, as it’s not advisable to compost feline feces because of their high content in toxins and germs, and dog feces require special measures when composting.

Leather goods can also make for good compost bin material. If you have old leather clothing, shoes, wallets or bags that you are sure can’t be used anymore, you can try composting them. Because of the processing, it’s likely that leather will take some time to break down fully, but it really won’t take as long as you might think looking at it.

Unbelievable as it may sound, the dust in your vacuum bin can make for a great compost ingredient. If you think about it, the composition of dust mostly particles of dead skin, lint, and various other small pieces of organic materials, aside from a few non organic ones, for good measure. You can either get paper bags for your vacuum cleaner, which you can compost as well, or buy a vacuum cleaner which uses a bin instead of bags and just empty the bin into the compost pile.

Speaking of paper bags, paper can make for a great compost ingredient. You can use all sorts of paper in your composter, except, of course, paper that has been laminated or the kind of gift wrapping that usually comes with a thin plastic layer on top. Aside from that, you can go crazy and compost anything from cardboard boxes to old newspapers and other kinds of paper that end up building up around the house.

You can also compost cotton balls, strange as it may seem. Cotton is organic, and as such, cotton balls should have no problem breaking down in your compost pile. Just make sure to check the packaging on the cotton balls you buy, because if they are made from synthetic fibers, composting them would be useless.

As you can see, there are plenty of things you can compost that you might not have thought were up to the task. All that’s left now is for you to have fun composting.
