CAPTION: “Pig waste used to be a big problem in the community, as the smell was very polluting”, Hue points out. With the extra income generated through pig rearing, she was able to install a biogas unit in her garden last year. Partially subsidised by We Effect, this turns pig waste into energy. LOCATION: Coong Village, Huy Tuong, Son La Province, Vietnam. INDIVIDUAL(S) PHOTOGRAPHED: Lo Thi Hue.
