EARTH has installed six bio-digesters on campus to reduce greenhouse gas emissions.  These bio-digesters collect human and animal waste and convert it into methane gas used for cooking and generating electricity.

Liquid petroleum gas consumption in EARTH’s cafeteria has decreased by 25 percent since 2009 when EARTH installed a bio-digester that collects wastewater from the University’s cafeteria, student dorms, laboratories and administration buildings, producing biogas to fuel three burners in the Institution’s cafeteria.
