LignoForceTM lignin as a polyol replacement in PU foams for thermal insulation applications

Rigid polyurethane (PU) foams have traditionally been used in thermal insulation applications. These foams, however, are characterized by a high carbon footprint and high manufacturing costs since the two main reagents used to make such foams are petroleum based and quite expensive. Hence, the objective of this work is to reduce the carbon footprint and manufacturing costs of PU foams by as much as 30% and 25%, respectively, by partially replacing petroleum-based polyols used in the manufacture of such foams with lignin, a natural polyol, derived from the black liquor of kraft pulp mills.
