Rigid Macroporous Wood Microparticles Impart Universality and Scalability to Lightweight Foam Insulation

open access: yesAdvanced Sustainable Systems, EarlyView.
Rigid, lightweight foams for thermal insulation are produced using a universal and scalable method: results are compared between pilot plant trials, four wood residues, pulp, ocean water, and a biosurfactant. Two guidelines for using this method are suggested: use a distribution of rigid wood microparticle sizes and shapes and match the average ...
