Recycling brewing by-products

The brewing process during the production of craft beer in this small firm in Canovellas, generates a certain amount of residues. For example, this liquid, which implies an additional cost if it has to be sent to a treatment plant.

Albert Tintó, head of production in ArtCervesers: “Should it go to our waste water, for every 1,000 liters of beer we produce, approximately 200 liters of additional waste water would be generated”.

A different type of residue arrives to this plant in Les Franqueses. The remains from demolition, which until now ended in a dumping site, are now recycled and reused.

Òscar López, head of the Tecnocatalana de Runes recycling plant: “95% can be used again in the construction process.”

The residues generated during the brewery process and rubble reencounter here. In the Sala Graupera garden center, in Sant Andreu de Llavaneres, these residues are reused to purify surplus irrigation water to be used again. The residues generated during the brewing process are added to the water and thanks to the sugar it contains it feeds the bacteria that eliminate the contaminants. Synthetic products are thus no needed.

On the other hand, the remains from demolition –previously crushed- filter the contaminants. This way there is no need to exploit natural quarries, we save money, and the water is treated.

Oriol Marfà, IRTA´s researcher: There are no more contaminants and we can thus choose between reuse it or pour it into the environment without contradictions.

IRTA has developed the system within a European project. Thus, several private firms will try to commercialize it, in Catalonia as well as in other parts of Europe.
