2.How long will your bags degrade ?
Decompose within 6 months in a controlled compost environment.
According to test standard EN13432 or ASTM D6400, products that are compostable-certified are those that compost within 180days only in industrial composting facilities ( at temperatures between 55 to 60°C). So usually when we refer to degrade time or compost time means under industrial composting condition, the bags will decompost within 6 months.
A number of factors affecting degradation rate, mainly microorganisems, light, water, oxygen, temperature. The chemical reactions proceed more quickly at higher temperatures. Over the course, microorganisms digest the object bit by bit and produce carbon dioxide, water -- as an indicator of degradation.
