This Little Piggie Went Wee Wee Wee

摘要

Pork is the most highly consumed animal meat globally, with the pig population currently numbering around 900 million worldwide. Australia has roughly one pig for every ten citizens, so pig production here requires significant effort to keep environmental impacts in check while remaining economically viable. Wastewater management is one of the important challenges. Piggeries are quite good at isolating their wastewater to prevent the contamination of nearby streams and groundwater, and this seems to be a proven part of the environmental strategy. The wastewater holding ponds utilised by piggeries also provide a treatment that involves anaerobic digestion of the waste to reduce the nutrient load and make the wastewater more manageable.
