In the controlled conditions of an industrial composting plant – high temperature and humidity, defined oxygen levels – microorganisms such as fungi and bacteria break the plastic down into water, carbon dioxide and biomass. In other words, they transform the bag and the bio-waste into valuable compost.

Composting is a controlled, aerobic (oxygen-required) process that converts organic materials into a nutrient-rich, biologically-stable soil amendment or mulch through natural decomposition. The end product is compost. Microorganisms feed on the materials added to the compost pile during the composting process.
