Biofuel from Tofu Waste

A tofu waste recycling facility opened a year ago here outside of Yogyakarta. Waste water from 400 kilograms of soybean used for tofu production is collected in tanks every day and undergoes fermentation.

The bio-gas generated in a treatment facility then flows into pipes connected to two tofu factories and 20 households.

"For the daily needs of the community, it is more economical to use bio-gas. At the same time the waste problem is solved."

The natural fermenting process also frees the waste water from polluting substances that used to leak into the river.
