Leather waste can cut out noise for leathergoods workers
20/01/2017
In an unusual example of the benefits of a circular economy, students from the National University in Bogotá found that leather waste worked well in soundproofing materials. They calculated that Colombian manufacturers generate around 90 tonnes of leather-trimming waste per year, with only a little of it going into small leathergoods. When they found that some of the waste was being ground for use in industrial materials, they carried out a series of experiments to test the material in soundproofing applications.
The result was that screens containing leather waste were capable of reducing the noise coming from machinery in footwear and leathergoods production units by five decibels. The same research team is now examining the possibility of using the material in building projects in the capital’s Restrepo district.
