Biogas Technology is a waste management tool and energy generation technology that uses locally available materials and an environment-friendly alternative. Biogas Production and Utilization is an on-going project of DOST-CALABARZON since 1994. As of December 2015, 408 Biogas plants have been adopted in livestock and poultry farms in various regions.
