Our products are designed to be composted using a process which does not occur in landfills. Microorganisms, carbon, water, oxygen, and nitrogen are all necessary elements of the composting process. If sent to an open landfill or dump where oxygen is available, compostables will degrade at a rate similar to other biodegradable materials in the same setting.
If compostable products are placed in the more common air-tight landfill and deprived of oxygen and microorganisms, they will not be able to biodegrade. This is true of all biodegradable materials in landfills, including paper, yard waste, and food waste.
Despite this fact, there are significant "upstream" benefits of compostable packaging including being made from renewable, less toxic materials by conscientious companies. For more information, check out our blog post about this topic.
