As ethanol production continues to ramp up, the volume of remnant by-product of dried distillers grain solids (DDGS) is becoming a bigger issue. Current uses include animal feed; however, only certain domestic animals can digest it as a meaningful feed.

Researchers at Purdue University have developed a process for using DDGS as a natural carrier for chemicals. Because it is known that grain will absorb moisture, researchers developed a process for reducing the DDGS to a uniform, microsized particle, coated with water-based chemicals. These tiny particles can spread uniformly across an intended area and have the potential for time-release delivery.

Advantages:
-Useful application for DDGS, which is abundant, but has limited
applications
-Potential use for time-release delivery

Potential Application:
-Agriculture
