Not all organic wastes will break down completely or safely in a backyard composting system. Home composters (especially beginner composters) should avoid certain items that may be more difficult to manage. Backyard compost piles are typically not hot enough to reach the temperatures that reduce pests and pathogens. Industrial scale compost operations can more easily achieve thermophilic composting in the range of 131-165 degrees F, which can destroy weeds, seeds, etc. and break down residuals like meat, bones, dairy products, etc. as well as more easily manage compostable paper products.
