Anaerobic digestion (AD) is the biological degradation of organic material in the absence of air. An anaerobic digester is a man-made system that harnesses this natural process to treat waste, produce biogas that can be converted to heat and electricity and anaerobic digestate, a soil improving material. Anaerobic Digestion (AD) is the preferred stabilisation process for the treatment of wastewater sludges and organic wastes. The process provides volume and mass reduction and delivers valuable renewable energy with biogas production.

Rennet is an enzyme that naturally occurs in cow stomachs. It is used in cheese making. Commercially prepared rennet from microbiological origins have made it possible to make cheese without harvesting rennet from live animals.
