46 Things You Didn't Know Were Compostable


Composting is one of the easiest ways to live a more sustainable lifestyle. It may come as a surprise, but a considerable amount of the waste that people discard each day can be composted. In America, approximately 30% of the typical household waste stream is compostable.


We've put together this list of 46 not-so-obvious compostable items.


Note: Some of these items (labeled with *) are not recommended for back yard compost piles, and should only be composted in an industrial scale setting due to the heat and monitoring practices used in professional methods. You can read more about the difference between backyard and professional composting here.
