Sustainable Development-Zero Emissions

In Fiji the waste from a brewery was causing environmental problems. A boys home project set out to utilize the waste as much as possible. The plant material in the waste was fed first to mushrooms that broke down the lignin. The cellulose could then be digested by pigs. The waste from the pigs generates methane. The digested sludge then grows algae in a pond and fish feed on this. The waste water is clean enough to release to the environment.
