Sustainable gypsum prefabricated from polyurethane foam residue
ES1241509
A research group at the University of Burgos has developed a procedure for the manufacture of a prefabricated gypsum using polyurethane foam waste (of industrial origin). The cost of the sustainable prefabricated product is lower than the traditional one and it also presents improvements in terms of weight reduction, increased insulating capacity and represents a viable solution for the recycling of polyurethane foam. In this way, it contributes to the circular economy, positioning itself as an alternative to traditional prefabricated gypsum.
- Cost reduction. The final cost of the material obtained is 12% lower than that of a traditional gypsum prefabricated product. - Improvement in the physical characteristics of the prefabricated material. - Weight reduction of up to 25% compared to standard boards. - Increase in the insulating capacity of the material produced. - Increased recycling rates of this waste.
