The recycling of cross-member composite (CMC) parts was studied using partial decrosslinking of the polyurethane (PUR) composite matrix by catalyzed glycolysis. The decrosslinked material, containing reactive OH and NH2 groups, was reacted with polymeric isocyanate in a molding operation to form a new composite product. In order to make the process economically feasible the smallest amounts of reactants (glycol, catalyst, isocyanate) were used in the process. The results of the laboratory study were verified in semi-pilot plant runs. The economic analysis showed that the process is feasible.

A systematic life cycle management (LCM) approach has been used by Chrysler Corporation to compare existing and alternate hydraulic fluids and lubricating oils in thirteen classifications at a manufacturing facility. The presence of restricted or regulated chemicals, recyclability, and recycled content of the various products were also compared. For ten of the thirteen types of product, an alternate product was identified as more beneficial. This LCM study provided Chrysler personnel with a practical purchasing tool to identify the most cost effective hydraulic fluid or lubricant oil product available for a chosen application on an LCM basis.
