Focus DMT Environmental Technology
François Hubert: ‘This project will soon make Waternet one of the largest suppliers of biomethane in the country’ The far-reaching influence of water technology is becoming clear once again in Amsterdam. Households and trucks in the Dutch capital will be supplied with Green Gas in the near future, produced by optimizing the local sewage treatment plant. Water Alliance member DMT Environmental Technology is working on it and explained the project to us.
