Every year around 734 million tons of wheat straw are produced worldwide, a large amount of waste, which is cheap and has had no well-defined use until now. Recently, the RNM-271 Chemical Engineering and FQM-383 NANOVAL Organic Chemistry research groups at the University of Córdoba have been able to give a new use to this agricultural excess material, by using it as the foundation in order to manufacture polyurethane foams.
Also known as foam rubber, this plastic material, often manufactured from petroleum by-products, is extremely versatile within the industry and has multiple uses in the construction and automobile sectors as a sealant as well as a thermal and acoustic insulator.
