Draft CWA ‘Extraction, production and purification of added value products from urban wastes — Part 1: Production and purification of ectoine obtained from biogas’

This CEN Workshop Agreement specifies an operational process for biogas bioconversion into ectoine, the extraction of the ectoine from the resulting solution and its purification.

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.

 

Currently, ectoine is one of the most profitable products produced by microorganisms. Due to its high effectiveness as stabiliser of enzymes, DNA-protein complexes and nucleic acids, ectoine has a value in the pharmaceutical industry of approximately 1,000 US$/kg and a global consumption of 20 tonnes/year.

 

The CEN Workshop agreement present a process for the production of ectoine from biogas in waste treatment plants. This type of plant does not present of any especial requirements and given the low amount of biogas required (67 Nm3/h) compared to the median biogas production in medium-scale waste treatment facilities (500-1000 Nm3/h), could be placed in all sort of waste treatment facility.

 

The draft CWA Extraction, production and purification of added value products from urban wastes — Part 1: Production and purification of ectoine obtained from biogas’ 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: 24 November 2022.
