Waste-to-energy is a form of energy recovery where by energy is generated in the form of electricity and heat via waste treatment.

Anaerobic digestion is a series of biological processes in which organic material are put under conditions where oxygen is absent and left to break down by microorganisms. Using anaerobic digester to process waste can reduce the load on landfill as organic food waste can be diverted from the landfill to generate compost and biogas.

Food waste collected can be sorted and segregated from impurities. It is then shredded and broken down to form bioliquid. After proper mixing of the bioliquid, it is then prepared to be fed into the anaerobic digester. Biogas is produced in the digester and is harvested to generate electricity and heat. The leftover digestate can be used as fertilizer.
