Description:
The goal of this Phase I project was to determine the feasibility of using a lignin-based additive to impede the leaching of borates from pressure-treated wood. Currently, borates can be used only in interior under-roof applications that are protected from rain, due to the tendency of borates to leach readily from wood. The lignin-based additive uses a stream available from lignin-recovery processes being implemented by the paper industry to remove lignin from their black liquor, unloading their Recovery Boilers, and increasing the throughput of their pulp mills. Liquid Lignin Company team has experience regarding chemistry and manufacture of lignin and has developed a strong network within the paper industry while developing their innovative SLRP® Process to recover lignin, which was funded initially by a U.S. Department of Energy SBIR in 2009.
