Folgende Antwort auf meine Mail an Carbios flatterte heute ins Postfach:
"Thank you for your email and interest in our technologies. There are several differences between Loop industries approach and ours. First our reaction catalyst is a biological tool (an enzyme = protein) whereas Loop is using solvents (Methanol) to breakdown PET plastics. As our enzyme has been designed to just to breakdown PET, Carbios approach is more tolerant to impurities and other products that can be found in plastic waste. Also, Loop solvents become by side products that will need specific treatment, while our enzyme is used under mild condition (water based, no pressure, no solvents) and it can easily be processed after use. Second, Carbios breaks down PET into its original building blocks: PTA and MEG. These are the monomers used by 95 to 98% of the industry to make PET. Loop breaks down PET into DMT and MEG. DMT was used 30 years ago to make PET but it has mostly been abandoned. Today, only 2 to 5% of the industry is still using DMT technologies and for quite specific applications (e.g. technical textiles). The PTA route reduced costs, generates only water as by products, it is also more stable and it require 70% less energy. At last, handling PTA is less dangerous than DMT on an industrial point of view. Meanwhile, both approaches have potential benefits and that's probably the reasons why L'Oréal, such as other brands, are partnering/investing with both of us. Also, the need for recycled PET is huge on the market and an efficient supply is only possible through the use of several innovative technologies such as the ones developed by Carbios and other players of the chemical industry. Should you need any additional information, please feel free to let me know. Best regards" |
