This deliverable contains information about innovative technologies with the potential to increase eco-efficiency in the industrial sector. Technologies were identified ac-cording to the environmentally weak stages in each of the four Case Studies exam-ined. The technologies are classified according to the stage at which they are implement-ed: Technologies in the water supply chain (common in all water use systems); implemented either upstream (e.g. water treatment) or downstream (e.g. wastewater treatment) of the water use stage. Technologies in the production chain. The technical description provided includes information about the working mecha-nisms, the environmental performance, cost data, technological maturity and justifica-tion for the necessity of each technology presented. This report is only available in Swedish.
