How long will they take to decompose in the compost pile?

Compostable bags take approximately 90-180 days to decompose depending on the composting environment. Industrial composting is typically quicker than home composting for two main reasons:

1) temperatures reached inside a home composting bin is usually only a few centigrade degrees higher than the outside temperature, and this is true for short time periods (in industrial composting, the temperatures reach 50°C – with peaks of 60-70°C – for a number of months).
2) home composting bins are managed by everyday people and the composting conditions might not always be ideal (in contrast, industrial composting plants are managed by qualified personnel and kept under ideal working conditions).
