    CEP (Ed.)
    Dr. Xiao Zhang’s group at Washington State University has developed new methods of producing high purity nano-dimension lignin, DESL (Figure 1) with controlled structural properties. With the support from NSF/IUCRC/CB2, we have demonstrated the preparation of high DESL containing semi-rigid polyurethane foam (Figure 2) with good physical properties. In addition to foam, DESL-based polyurethane has shown potentials for adhesives, sealants, and coatings applications. We are working with CB2 ember companies, including: AkzoNobel, BASF, Ford, Idaho Forest Group, etc., toward commercialization of this new technology. This technology will optimize the utilization of agricultural/forest wastes to decarbonize PU industry and create new economic and job opportunities in US.
