Session 2: Waste Flows as Sources of Raw Materials and Énergy
The world population is growing every year by the number of inhabitants of Germany, the often vital natural resources, above all drinking water, are, however, limited. Even today some industrialised countries suffer from drinking water scarcity. The implementation and application of water-related European Directives (e.g. Urban Waste Water Treatment Directive, Water Framework Directive) can only be a contribution among many others to ensuring future generations the security of supply with drinking water. Municipal authorities and entrepreneurs are rather both called upon to find appropriate measures to increase the water efficiency and to close the water cycles. Waste water, where it cannot be avoided, becomes thus a resource, from which again drinking water or industrial water, but also energy in the form of heat, biogas, sewage sludge, as well as other substances, can be generated.
Technological innovations and management techniques for a sustainable water management which is already now offered by the water and environmental technology industry constitute a major priority in session 1 of the Waste and Water Management Track. System solutions help the responsible communities, water supplier and waste water treating enterprises, as well as the users of water to cope with the ever increasing ecological challenges as presented on the basis of concrete examples.
The new EU Waste Framework Directive sets goals for the reuse and the recycling of certain waste flows. Thus by the year 2020 50 % of paper, metal, and glass from household waste and similar waste flows as well as 70 % of the non-hazardous construction and demolition waste shall be reused or recycled. Here, especially municipal authorities and communities are called upon to use cost-effective methods of waste management and the innovative recycling and recovery technologies offered by environmental technology enterprises for this purpose.
Session 2 deals thus with approaches to solutions how to recover for example from demolition waste utilisable recycling building materials, from end-of-life vehicles, electrical and electronic equipment and batteries reusable resources, or how to get from biowaste products such as high-quality compost and energetically usable biogas. Thus waste flows are used efficiently as anthropogenic sources of raw materials and energy, and material flows are closed.
