Turning waste into power cleans up village lifestyle

Pig, poultry farmers play a central role in Sichuan's battle to cut water pollution

Liu Huaiyu raises more than 200 pigs in her farmyard, which houses one of the largest piggeries in her village, and the prodigious amount of manure they generate every day never bothers her. It is a source of extra income for her family.

"The village government has subsidized us to expand our methane gas generating pit, and bought our extra biogas fluid. So nothing is wasted any more," said 43-year-old Liu.
