Integrated Biogas-microalgae from Waste Waters as the Potential Biorefinery Sources in Indonesia

Abstract

Microalgae can produce not only bioenergy (e.g. bioethanol, biodiesel, biogas, and hydrogen) but also other value products (e.g. paraffin, olefin, glycerol, protein, anti-oxidant, pigment, plastic, etc.). To reduce the production cost, we could utilize the waste water streams as the growth medium. Microalgae cultivation can also be integrated with biogas system from agricultural waste waters (e.g. tapioca waste, palm oil mill effluent, and other agricultural wastes).
