Cleaning Up the Tofu Industry: Indonesia

Overview

Tofu is a staple of Indonesian cuisine. Over 80,000 companies nationwide make it. Most are family-run. Wastewater from the process is a major environmental problem. It's dumped into rivers, polluting them with organic matter. The Indonesian government has created a system that uses bacteria to dissolve the pollutants and produce methane, which is sold to local households. We look at a pilot project that has huge community support.
