In Yucatan, there are estimated to be more than 490 000 pigs, which generate about 29 000 cubic metres of waste water and 166 tonnes of organic waste per day. Yucatan’s water table has been absorbing much of these wastes as a direct consequence of the Peninsula’s inadequate treatment systems and a lack of knowledge concerning the linkages between production and environment degradation. Technologies to reduce the environmental impacts There are many technological options which can contribute to the mitigation of pollution from pig production.

Disposal of pig manure is usually driven by lowering disposal costs rather than optimising the nutrient needs of crops and pasture, leading to detrimental environmental costs. Because pig manure is a low density nutrient fertiliser source, and costly to transport over long distances compared to inorganic fertilisers, areas with high intensity pig production usually have a surplus of nutrient manure. This has led to an increase in residual pig manure in the environment in these areas, where they can degrade water and air quality and impose human health and environmental pollution costs on society.
