The direct use of these specific enzymes is therefore another alternative for breaking down polymers. \u2018The monomers obtained as a product of the degradation reaction can be recovered and used to synthesize new products, thus making it a sustainable chemical recycling method,\u2019 the researchers note.<\/p>\n<p>Lab tests has shown that the enzymes can help degrade certain polymers like polyurethane film by up to 70%. It is pointed out that the optimal working temperature of enzymes is 25-95\u00baC. This is a lot less than the 180-230\u00baC temperature range conventional methods require, meaning the innovation notably curbs energy consumption.<\/p>\n<p>The work is explained in more detail in a paper prepared for The Plastics Recycling Update.
