Producing novel non-plant biomass feedstocks and bio-based products through upcycling and the cascading use of brewery side-streams.

CHEERS is an EU-funded project under the Horizon Europe program (HORIZON-CL6-2021-CIRCBIO-01-05) led by Mahou San Miguel with a consortium of 11 partners from 5 countries.

The project aims to revalorise under-utilised or waste by-streams from the brewing industry for subsequent conversion into five high value-added industrial bio-products through a biorefinery approach.

End-users of CHEERS ingredients will be mainly companies using these products as feedstocks for other industrial processes (human nutrition, sanitation, animal feed, petfood, cosmetics).

CHEERS consortium at AINIA for kick off meeting.

The initiative proposes to achieve a reduction in the resource use and environmental impact of the beer production chain and aims to cover wider impacts on biodiversity and agricultural land use.

CHEERS will develop sustainable transformation processes using innovative biological platforms inspired by nature, which will be validated on a demonstration scale at Mahou San Miguel’s brewery.

An integral solution for the valorisation of all by-products and side-streams via 2 novel bio-based production platforms (insect and microbial) and 5 bio-based products.

  • Insect based upgrading og bagasse into 13.5 ton/y of insect protein for drinks.
  • Microbial conversion of CO2 and wastewater into 700 kg/y caproic acid for feed.
  • Microbial conversion of CO2 into 50 kg/y chlorine for sanitizing products.
  • Microbial conversion of biogas into 20kg/y of ectoine for cosmetic products.
  • Microbial conversion of biogas into 482 kg SCP/y for pet food production.
