Recovering phosphorus from corn ethanol production can help reduce groundwater pollution

(University of Illinois College of Agricultural, Consumer and Environmental Sciences) Dried distiller's grains with solubles (DDGS), a co-product from corn ethanol processing, is commonly used as feed for cattle, swine and poultry. However, DDGS contains more phosphorus than the animals need. The excess ends up in manure and drains into the watershed, promoting algae production and contributing to dead zones in the Gulf of Mexico. A new study from University of Illinois provides a simple method to recover phosphorus from DDGS in dry grind processing.
