This is how waste from tofu is converted into biofuel. #Tofu #BioFuel #Sustainability

tofu is a staple across Indonesia almost every step of making tofu generates Wastewater when that flows into nearby streams the acidic runoff can kill off fish and crops but now some Villages are converting stinky Wastewater into home cooking fuel pipes carry waste water directly from the cluster of tofu factories to a nearby biogas plant the six tall black tanks turn waste into biogas the Wastewater gets pumped into the first reactor from the holding pond then technicians introduce anaerobic bacteria which don't require oxygen to break down organic material as the microbes munch on soy proteins the series of six digesters produces methane a gas that can be used as fuel the whole fermentation process takes about 20 days but technicians feed new biomass into the reactors every day
