Corn Leftovers Find New Life in Biomaterials

By Scout Nelson

A new partnership in South Dakota shows how agriculture and science can work together to create new opportunities. South Dakota Mines and Dakota BioWorx launch a bioprocessing effort that turns corn stover into advanced biomaterials. Corn stover includes leftover stalks and leaves after corn harvest and is often unused.

The project connects research from South Dakota Mines with Dakota BioWorx’s bioprocessing facility in Brookings. Researchers use special heat-loving microbes and engineered processes to convert corn waste into bio-based materials. These materials may support future medical uses, including soft tissue support and drug delivery systems.

This effort creates one of the first thermophilic biomaterial biorefineries in the nation. It places South Dakota as a growing center for sustainable biomanufacturing. The project shows how local farm products can support high-value industries beyond food and feed.

Production begins at the pilot level using fermentation systems. Small-scale runs help researchers test and improve the process. The team plans to increase production size over time. This approach helps move ideas from the university lab into real manufacturing settings faster.

The partnership also supports education and workforce growth. Students gain hands-on experience in fermentation, bioprocess engineering, and biomaterial testing. These skills prepare students for jobs in the expanding biotechnology sector.

Local farmers and rural communities also benefit. The project uses corn residues grown in the region and keeps processing and development inside the state. This adds value to crops while supporting local jobs and business growth.

The materials produced are refined into nanogels. Nanogels are soft materials that can be adjusted for different uses. Future research focuses on testing these materials in medical settings to confirm safety and performance.

This collaboration builds on South Dakota Mines’ strength in biomaterials and composite research. It offers a clear example of how states can lead manufacturing growth by using their own resources, research, and skilled workforce. The project highlights a practical path for agriculture to support innovation, sustainability, and long-term economic development.
