Tofu waste turns to gas: Video Report
Aug 28 - Tofu factory waste is being turned into energy in Indonesia.
Indonesians in a central Java village are turning tofu factory waste into energy, reducing both air and water pollution and offering an alternative to fossil fuels. Soy-rich wastewater is left to ferment, and the biogas produced is used by two tofu factories and 20 households in the area.
