Transcript:

The government of Indonesia is spearheading a new environmental project. It is looking to convert wastewater produced during the production of tofu into biogas. This is a huge improvement compared to the mere disposal of waste into rivers.
The project will use an ingenious method to treat wastewater, pumping it full of methane. The reaction with methane produces biogas that can be used to power homes and waste that can be used as fertilizer or be safely dumped into waterways.
Should the project be successful, projections estimate that it could bring down Indonesia’s pollution levels by as much as 26% by the year 2020. Moreover, it can produce close to 25,000 liters of biogas every day, far more than what the test village needs, using only 91 liters per day.
Compare to LPG, LNG, coal, and oil, biogas is a cheap energy source with fewer harmful effects. Moreover, the waste-to-fuel conversion helps to bring down the cost of living in the long run.
