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.

Wertstoffhof 2020 - Neuorientierung von Wertstoffhöfen
© ia GmbH - Wissensmanagement und Ingenieurleistungen (4/2015)
Im Jahr 2014, zwanzig Jahre nach dem durch das Bayerische Staatsministerium für Landesentwicklung und Umweltfragen organisierten Wettbewerb „Der vorbildliche Wertstoffhof“, ist es sicher angebracht, sich dem Thema erneut zuzuwenden. Was ist aus den prämierten Wertstoffhöfen der Preisträger in den jeweiligen Clustern geworden? Wie hat sich das System grundsätzlich entwickelt? Wo geht es hin, wenn man die gesellschaftlichen Anforderungen aus demografischer Entwicklung, Ressourcenschutz und Klimarelevanz betrachtet?

Municipal Solid Waste (MSW) constitutes a serious problem in urban areas. A waste hierarchy is often suggested and used in waste policy making. Different versions of the hierarchy exist, but in most cases the following order is suggested: 1. Reduce the amount of waste, 2. Reuse, 3. Recycle materials, 4. Incinerate with heat recovery, 5. Landfill. The first priority, to reduce the amount of waste, is generally accepted. However, the remaining waste needs to be taken care of as efficiently as possible. The hierarchy after the top priority is often contested and discussions on waste policy are intense in many countries.

System impact comparisons are made at all levels of society. At the individual level: should I buy a small economical car and rent a bigger one when I need to transport bigger items, or shall I buy a bigger car? At the industrial level when facing escalating labor costs: should my enterprise invest in a new production unit in a Low-Income Country (LIC), or should I robotize my existing enterprise in the High-Income Country (HIC)? Often we tend to make these impact comparisons or parts thereof rather intuitive and equally often our impact comparisons turn out to cover only those aspects of the system which are relatively easy to compare. It goes without saying that this way we may miss out on elements which are of importance.
