What is the difference between a homemade composting and the industrial composting?
The difference comes from the temperature and the composting time. Industrial composting requires a temperature of 75-80C, a humidity rate of 65-70% and an oxygen rate of 18-20%. In these conditions, composting takes around 12 weeks. In garden compost, temperature never exceeds 40C and humidity will depend on the time of the year, the season, and the latitude. Composting will be far longer, it can take up to several months.
