The Role of Thermal Treatment in Integrated Waste Management Concepts

The economic benefits of resource-and environmentally-friendly activities outweigh any economic cost disadvantages by far. The annual increase in global population is currently over 100 million persons. That means that each year a dignified existence of 100 million people including their rights to natural resources must be ensured. The assumption is not exaggerated that in the near future, producers of both industrial and agricultural products that do not consider the sustainability factor in their choice of production processes risk to lose their competitiveness.

In relation to waste management, the considerations outlined above lead to a hierarchy of choices with a priority placed first, on waste prevention and second, on waste recycling.

Alone in the European Union, hundreds of thousands of different products are bought and sold, with new ones added daily. Worldwide, some 12 million chemical compounds are bought or sold. It is inevitable that, in spite of all prevention and recovery strategies, a significant proportion of goods consumed will become waste at the end of their useful life. This waste consists of a wide variety of different components, including heavy metals, plus a variety of organic materials such as polychlorinated biphenyls, dioxins, furans, etc. which individually or in combination produce negative effects on humans and nature, though their human toxicological classification is often not known. Therefore, it is one of the most important tasks of waste management to treat waste in such a way that its properties affect the environment no more than the naturally existing level of emissions present in the natural environment.

Bioabfälle machen 34 % der Siedlungsabfälle aus und bilden damit die größte Abfallfraktion im Siedlungsabfall in der EU. Rund 40 Millionen Tonnen Bioabfälle werden jährlich in der EU getrennt gesammelt und in ca. 4.500 Kompostierungs- und Vergärungsanlagen behandelt.

Auch mittel- bis langfristig steht zu erwarten, dass die Kaskade aus anaerober und aerober Behandlung Standard für die Biogutbehandlung sein wird.

Die Mischung macht‘s - Der Gärrestmischer in der Praxis

Zur Nachbehandlung von Gärrest aus Bio- und Restabfall entwickelte Eggersmann den Gärrestmischer, der aus Gärresten und Zuschlagstoffen homogene, gut belüftbare Mischungen erzeugt. Damit wird den besonderen Anforderungen der Gärreste mit hohem Wassergehalt begegnet und eine effiziente Kompostierung ermöglicht.
