Regenerative Energie
As one of the cornerstones of sustainable materials management, integrated solid waste management strives towards the harmonization of economic, environmental and social benefits by appropriately steering post-consumer material flows. The adequate management of waste streams from society requires the integration of different technologies into a system, which minimizes the hazards on human health and the environment and maximizes the resource recovery, while being economically and socially sustainable.
In order to quantify and compare the environmental impacts caused by several modern household waste management strategies in the federal state of Baden-Württemberg, Germany, the Life Cycle Assessment (LCA) cradle-to-grave analysis, which accounts for the material and energy flows during the life cycle of a product or service, has been applied. In the case of household wastes, the environmental impacts through out the waste management chain correspond to the sum of the impacts that arise during the end-of-life operations of each product that leaves households as waste. The LCA carried out included the evaluation of the direct impacts arising from household waste management strategies, as well as the benefits obtained through the substitution of raw material and primary energy sources. The operations evaluated include the collection and transportation of wastes, material and energetic recovery, anaerobic digestion, residual waste treatment and final disposal. For the treatment of residual waste, incineration, mechanical-biological treatment, and mechanical biological stabilization were modeled, since they represent the state of the art in the Federal Republic of Germany in terms of waste treatment technologies.

Die Verwendung von Biogut- und Grüngutkompost ist eine Möglichkeit, Nährstoffdefizite im Ökolandbau zu vermeiden sowie die Bodenfruchtbarkeit zu erhalten und sogar zu steigern.
