EULEN CIRCULAR CLEANING is an innovative sustainable area, which allows cleaning services with EU Ecolabel certification. It has a high environmental impact with more than 280 environmental improvement actions, which increase sustainability through the reduction of raw materials, which minimize waste, the CO2 footprint and the water footprint. In addition to reducing consumption, it helps to close the circle, giving a longer life cycle to the service through reuse. Technology is another element to act when and where it is really needed. The results are monitored by an innovative environmental calculator. The idea is that more and more sustainable elements are interlocked in the cleaning process, with the collaboration of all parties, from the client, the service providers, and the end user of the facilities so that everyone joins in circularity.
