Essay on Materials Development. Paper must be at least 250 words. A wool carpet manufactured using this innovative system is a completely natural and biodegradable product. At the end of its useful life the entire product can be shredded and turned into organic material, which can then be used, for example, as fertilizer for growing plants. The work has been carried out for the Netherlands companies Bond Textile Research, Best Wool Carpets and James, which own the four patents on which this new biological technology is based. The so-called “cradle-to-cradle” model has been central to the work done by the team led by Tzanko Tzanov, a researcher with the Molecular and Industrial Biotechnology Group at the Universitat Politècnica de Catalunya. BarcelonaTechs Terrassa Campus. The outcome is an enzyme-based biological technology that paves the way for three Netherlands companies to manufacture carpets that are much lighter, sustainable, biodegradable, and 100% recyclable. At the end of their useful life, the carpets can be used as fertiliser or substrate for growing plants. The system saves a great deal of energy, completely closes the biological cycle for wool, and significantly reduces the final cost of carpet products.Universitat Politècnica de Catalunya (UPC).
