This CEN Workshop Agreement defines the process for extraction and purification of PHA biopolyesters using chlorinated solvent-free and wet chemistry methods from enriched biomass.
The Workshop Agreement is a result of the European R&I project DEEP PURPLE funded by the European Union under the Horizon 2020 program (Grant Agreement No 837998). The process is based on the recovery of bioproducts from the treatment of urban bio-waste as an inexpensive and sustainable carbon or/and nutrient source for biomass growth to be further transformed into high added-value products for different industrial sectors.
PHA polymers are both bio-based and bio-degradable and therefore have attracted much attention over the last four decades as an alternative to commonly used non-degradable plastics. PHAs possess similar physical properties to polyethylene (PE), polypropylene (PP) and polyethylene terephthalate (PET) which currently dominate in the packaging industry.
The draft CWA 17897-2 ‘Extraction, production and purification of added value products from urban wastes — Part 2: Extraction and purification of PHA biopolymers’ is now available for commenting.
You are kindly invited to submit comments on the draft CWA to the WS secretary Elena GAYO MONCO (egayo@une.org) using the below commenting form.
Deadline: 10 June 2023.
