For a few weeks now, the Spanish brewery Damm has been withdrawing the barrels of beer opened in the establishments of all its hotel customers in Spain, replacing them with new barrels as a support measure for the sector in its reopening.

The brewery estimates to recover a total of more than 3.5 million liters of beer, a product which, in line with its constant commitment to the circular economy, will transform into renewable energy at its factory in El Prat de Llobregat (Barcelona) .

The beer that Damm withdraws from catering establishments is transported to the El Prat factory in Llobregat for its transformation into energy from a 100% green source. Beer is placed in tanks containing specific microorganisms which digest it, producing a gas of biological origin: biogas. Subsequently, once separated, the biogas is washed and purified and used as fuel in a cogeneration plant which produces 100% renewable electricity.

One of the fundamental axes of our environmental sustainability policy is the commitment to the circular economy. So instead of generating waste from recovered beer, we are giving it a second life by transforming it into renewable energy, a measure that will allow us to reduce our carbon footprint by around 250,000 kg..

Through this process, we estimate that we will produce almost 670,000 kWh of electricity, equivalent to the average monthly consumption of some 2,500 Spanish households.

This initiative joins all those that Damm leads during the process of manufacturing, bottling and distribution of its beers, which has consolidated it as one of the five companies that promote the circular economy the most in Spain, according to the report on the circular economy prepared by the Institute of Coordinates of Governance and Applied Economy, which underlines, among other data, that 99% of raw materials are recoverable and reincorporated into the production chain.
