The Spanish packaging company Estal presented an innovative and sustainable cork and activated carbon closure at ProWein in Düsseldorf. The new Corkcoal features a combination of cork and activated carbon from renewable sources and is said to reduce the CO2 footprint due to its resource-saving manufacturing process. This reduces residues, raw material waste and industrial cork washing processes and eliminates the use of chemical bleaching agents. In addition, the biodegradation process of the corkcoal is accelerated by the activated carbon.
In addition, the use of activated carbon is said to enable better organoleptic results. In return, the activated carbon naturally absorbs and neutralises undesirable substances in the cork. According to Estal, the Corkcoal is almost neutral due to the materials used. It is available in three models: Sharp, Barrel and Cornice, in two sizes: 21.5 and 18.5 mm.
