The term "compostable" refers to a product or material that can biodegrade under specific, human-driven circumstances, according to Compostable package manufacturers.
Unlike a completely natural biodegradation process, composting requires human intervention.
Compostable package manufacturers say that if the material is compostable, it means that under composting conditions i.e. temperature, humidity, oxygen and the presence of microorganisms, it will decompose into carbon dioxide, water and nutrient-rich compost within a specific time. The composting process usually takes a few months or 1-3 years. According to Compostable package manufacturers, there are two main types of compost:

1. Home Compost
Compostable package manufacturers say that household composting involves collecting food scraps in a bin or heap, mixing it with yard waste and breaking it down into more basic organic matter on a regular basis. Household composting containers have smaller capacities and are often exposed to ambient temperatures. In this case, the compostable material will decompose within 180 days.
2. Commercial or Industrial Composting
Compostable package manufacturers say that commercial or industrial composting involves screening and sorting organic and inorganic materials, breaking them down with chippers and grinders, and creating optimal humidity, temperature and oxygen conditions. The same compostable material will break down in about 90 days under these conditions, about half as long as household compost.
