Water emission Water emission control includes returning puri fi ed water into the water cycle and reducing the aquatic environment impact to a minimum. Effective ways include the use of sustainable components, the optimization of production, and the use of wastewater treatment technology. An intelligent selection of process components helps to minimize the amount of harmful substances in wastewater. Ecolabels and Organic Certi fi cation for Textile Products 185

As a consequence, the basic contamination of sewage can be reduced. Manu- facturers are also requested to install well-functioning wastewater treatment. Air emission Each process step of textile production causes air emissions. The Bluesign system effects all areas and process steps by directly targeting the basis: the selection of raw materials and chemical products. It speci fi es strict selection criteria for substances and components having an emission impact. The aim is to reduce CO 2 emissions within the company s sphere of in fl uence as well as during the subsequent process steps. Exhaust air has to be cleaned and recycled by adequate environmental technology. This is the essential condition in order to reduce greenhouse gas emissions and to make an active contribution to climate protection. Occupational Health and Safety The health and safety of employees in the textile industry have to be safe- guarded by strict guidelines. Localized problems have to be detected. Safety measures, according to the risk potential of deployed chemical substances, are mandatory. Occupational health and safety also includes protection against environmental pollution, such as dust and noise. In fact, the basic principle of the Bluesign system is to eliminate harmful sub- stances from the very beginning, guaranteeing the application of sustainable ingredients in a clean process, at which end stands a safely manufactured product, irrespective of the number of process steps or manufacturers involved. The pro- ducers must take into account the positive list of accepted chemical inputs. Bluesign has a rating system for each applied chemical component based on the criteria described above. Chemicals are categorized as follows: Blue category components meet all of the Bluesign criteria and requirements. Grey category components can only be used under certain appropriate conditions. Black category components do not meet the Bluesign criteria. Web applications are available, for chemicals, manufacturers, and brands/ retailers. 6 Organic Certi fi cation The trend for buying organic products is mainly related to food. Organic certi fi - cation is a certi fi cation process for producers of organic food and other organic agricultural products based on several requirements the most important of which are related to avoiding synthetic chemical inputs, such as fertilizers, pesticides, antibiotics, and food additives.

irradiation, and the use of sewage sludge are also forbidden. This trend has also emerged in textile fi bers.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
