Open Market Consultation process launched by LIPOR

In the context of the HOOP project, which is driving innovation to Vitalise Urban Bioeconomy, LIPOR launched an Open Market Consultation to find solutions for nutrient recovery present in the liquid digestate coming from the future anaerobic digestion plant.

Starting from a project to build an anaerobic digestion plant, for 60,000 tons of food waste, the challenge for the market is related to the treatment of the liquid fraction of the digestate produced, after phase separation (effluent), in order to respond to legal requirements for discharge/treatment in a WWTP and, at the same time, recover nutrients (phosphorus and ammonia nitrogen), for valorisation and production of new bioproducts. Both nitrogen and phosphorus are valuable nutrients essential for fertilizer products. This is of interest for regional agriculture.

In compliance with the public procurement principles, all interested experts, independent authorities, and economic operators (regardless of their geographic location, the size or governance structure of their organisation) are invited to take part in the Open Market Consultation.
