Abstract:

The main objective of GREENBIOREFINERY is to develop new strategies to generate bioproducts with the integration of both the brewery wastes’ treatment and the production of microalgal biomass, enhancing this way the economic and environmental sustainability of the process as a whole. This integration will enable the transformation of these wastes of the brewery industry into biomass of interest. This will allow not only the reduction of the environmental impact of beer fabrication processes, but also a recovery of the nutrients (C, N, P) contained in the wastes and their conversion to high-value compounds. To achieve this objective, the wastes produced will be characterised to be used as feedstock into the microalgae’s production by previously selected companies. Finally, the developed technology will be escalated to pilot-scale with 1m3 photobiorreactors to validate and assess the process as a whole. As a result, we aims to develop flexible and adaptable processes of integral exploitation of the microalgal biomass which could be applicable in different breweries taking into account local necessities and possibilities.

Objectives:

  • Characterization of liquid and gaseous wastes derived from brewery industry in terms of its feasibility as raw material for microalgae production Design of a strategy for the treatment and use of brewery wastes using microalgae cultures
  • Evaluation of productivity and composition of microalgae grown in brewery wastes at laboratory scale, in addition to its depuration capacity
  • Development of biorefinery concept for the integral valorization of produced biomass minimizing the release of wastes.
  • Demonstration of the process at pilot scale and evaluation of its economy and feasibility.
