Transforming Biodiesel Waste: The Future of 3D Printing with Soy Byproducts
The 3D printing and biodiesel industries, researchers at the University of Louisville have discovered a method to repurpose waste from soy biodiesel production into valuable 3D printing filaments. This innovative approach, led by Dr. Jagannadh Satyavolu, turns matter organic non-glycerol (MONG), a significant waste byproduct, into copolymers suitable for 3D printing. This not only provides an eco-friendly solution to waste management but also opens new possibilities for sustainable manufacturing.
Dr. Satyavolu’s team focused on converting MONG into usable 3D printing filaments by improving its thermal stability through various treatments. They explored two main pretreatment methods: acid treatment and a combination of acid and peroxide. The latter method proved most effective, resulting in a stabilized paste with reduced soap content, increased crystallinity, and the formation of low molecular weight small chain fatty acids. These characteristics make MONG an excellent candidate for copolymerization with thermoplastic polymers.
Dr. Satyavolu explains, “Our approach not only addresses the waste issue associated with biodiesel production but also provides a new, sustainable material for the rapidly growing 3D printing industry.”
Findings and Implications. The researchers’ comprehensive analysis of MONG’s physicochemical properties, fatty acid profile, and thermal stability revealed promising results. Treated MONG displayed improved properties that make it a viable alternative to synthetic polymers used in 3D printing. Specifically, the acid and acid + peroxide treatments effectively split soap, reduced water solubility, and increased glycerol content, enhancing the material’s suitability for 3D printing applications.
One notable outcome of the study was the increase in formic acid and oxirane concentration after the acid + peroxide treatment, indicating successful epoxidation. This is a crucial factor in improving MONG’s thermal stability, making it more suitable for 3D printing filaments. The utilization of MONG in 3D printing is a significant step toward sustainable manufacturing. By transforming a waste product into a valuable resource, this research supports the development of carbon-neutral composites, contributing to a more sustainable future. Over the next ten years, we can expect to see more advancements in the use of biodiesel byproducts in various applications, further integrating sustainability into industrial practices.
Dr. Satyavolu adds, “Our findings suggest that with continued research and development, MONG-based materials could become a staple in the 3D printing industry, promoting both economic and environmental benefits.”
