Water problem addressed: Too dirty

Summary: The surplus of pig manure has become an environmental challenge in Catalonia and in numerous other parts of the world. Traditionally, pig manure is applied into agricultural fields as a natural fertilizer. However, the large amounts generated at some locations exceed the ability of surrounding areas to accept its high nutrient (mainly nitrogen and phosphorous) contributions. That imbalance frequently raises the need of transporting considerable amounts of such diluted waste to further distant fields, increasing the cost of waste management. Moreover, current waste treatments are expensive. Soil application of excess amounts of pig manure can result in groundwater pollution, which is a pressing environmental problem in farming areas. At the same time, there is a need for promoting renewable energy sources, and microalgae are known for its great potential for contributing to bioremediation and energy generation.
