Brief Project Summary:
Our overall goal is to partially substitute the hydrocarbon-based adhesives used for bonding engineered wood with soy flour. Complete market capture would lead to an annual demand of 13 million bushels of soybeans. Several successful full-scale mill trials have already been run for fiberboard, and our first goal is to convert these trials into continuous commercial operations at Jeld-Wen, one of our partner companies.

Final Project Results

The primary objective of this project was to incorporate soy flour as a commercial replacement for isocyanate resins in the production of hot and cold pressed wood composite panels. This transition has become necessary as wood composite manufacturers are shifting away from using phenol formaldehyde (PF) due to concerns regarding formaldehyde emissions. The primary alternative is the use of polymeric methylene diphenyl diisocyanate (PMDI) adhesives. However, the adoption of PMDI adhesives can be challenging due to their higher cost, lower tack, and lower viscosity compared to PF. To be economically viable, soy substitution must not only reduce costs but also maintain or enhance product properties by reacting effectively with PMDI. Significant progress has been made in developing methods to mix and optimize this reaction scheme, with successful laboratory experiments conducted this year. These achievements have led to specific deliverables, including successful mill trials at Jeld-Wen for medium-density fiberboard production and at Great Southern Wood for preservative-treated porch columns. Additional mill trials are in the planning stages for further assessment. Furthermore, ongoing plans are being formulated to conduct trials at a CalPlant facility specializing in rice straw medium-density fiberboard production.

Benefit To Soybean Farmers

Successful completion of mill trials will lead to commercialization, which will lead to soy flour sales that will benefit all US soybean farmers.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
