S2 Ep8. A cow’s amazing stomach could hold the key to stopping wastewater pollution. Engineers have designed a new sewage treatment plant based on a cow’s unique digestive process. Wastewater is progressively cleaned by microorganisms until it’s safe enough to be released into the environment. This new plant does not need electricity to operate, so it’s environmentally-friendly.
