Abstract
While plastic and e-waste dominate public discourse, municipal waste, particularly bulky wastes pose a significant challenge due to their large-scale generation aligning with the enrichment of society. Their efficient collection and keeping in a loop should be considered among the priorities of municipal waste management. Herein, the presented work presents novel composite materials obtained from flexible polyurethane foams used as mattresses and medium-density fiberboards applied in furniture products. Composites have been prepared using compression molding, with the addition of an innovative binder composed of a diisocyanate and inorganic salt, whose in situ decomposition led to the gas generation providing the porous structure and strengthening the interfacial bonding inside the material. The impact of changes induced by the chemical interactions on the appearance, morphology, mechanical, thermal, acoustic and insulation performance of composites has been evaluated. Observed changes pointed to the auspicious conclusions on the further applications of the examined binder composition.
