VietNamNet Bridge – Shrimp waste – heads and shells – are being used to produce animal feed and biological derivatives, resulting in high profits and a reduction of air pollution at processing plants.

Six years ago in Ca Mau province, the ‘metropolis’ of the aquaculture and seafood processing industry, shrimp shells discharged from processing were in piles as high as a mountain.
Every day, Minh Phu Seafood JSC threw away 50-100 tons of shrimp heads and shells. The mountain of shrimp waste produced a bad odor after being exposed to the sun and rain.
