Microbial and abiotic degradation of fully aliphatic polyurethane foam suitable for biotechnologies
Original language description
Polyurethane (PUR) foams are due to their versatility highly demanded not only in traditional applications but also in biotechnological and environmentally-oriented processes in which they can reach the open environment. Therefore, new PUR foams with degradation-on-demand features are highly desirable and their (bio)degradation behavior has to be understood. Herein, we have studied abiotic and microbial degradation of fully aliphatic PUR foam, developed as a biomass carrier for biofiltration. The progress of abiotic hydrolysis shows complete degradation of soft polyol segments and partial cleavage of hard isocyanate-derived segments. Microbial in-vitro degradations showed much higher activity of fungus Fusarium solani than bacterium Pseudomonas sp. Biodegradation of the PUR foam in soil reveals that 77% of the soft segments are mineralized after 6 months reaching the final mineralization of 43%. The results demonstrate that a non-hazardous and sustainable PUR foam can be successfully prepared for applications requiring material bioactivity (biorecycling, etc.). © 2021 Elsevier Ltd
