Regenerative Energie
Sustainable resource management and active climate protection as well as the longterm rise in energy prices determine the decision-making processes of municipal waste service providers. Optimised energy utilisation from waste is is a major priority in the strategy of BSR (Berlin City Cleaning Services). As a result BSR started up an organic waste fermentation plant in 2013. The biogas is processed and transformed into biomethane, which is fed into Berlin‘s gas distribution network and then used as fuel for BSR‘s waste collection vehicles that run on natural gas, thereby replacing about 2.5 million litres of diesel.
Energy production and energy costs are of course important economic parameters for formulating the waste disposal chargesapplied by BSR. On the one hand BSR is benefitting from increasing revenue for energy derived from waste incineration and landfill gas-operated block heat and power plants, and on the other hand BSR suffers from increasing energy costs, especially with regard to diesel fuels.
Against the background of the anticipated development of energy prices, BSR has developed the direct substitution of diesel fuels as the most economical and also the most ecological option. In economic terms the calculation takes rising diesel and gas costs into account and in ecological terms the direct utilisation of biogas results in eliminating all forms of conversion losses.
In December 2012 BSR was nominated for the German Sustainability Award 2012 in the category of Germany‘s most sustainable initiative for its concept of collecting and utilising organic material. Furthermore the fermentation plant, in conjunction with utilising the biogas as a fuel, won a prize in the environment category in October 2013 as an excellent place in the land of ideas.
BSR‘s concept for a facility that treats organic waste allows us, by reducing transport and diesel procurement costs, to keep increases in our charges to a minimum and at the same time to increase our production of green energy by extending the value chain. This concept - which includes fuelling over 150 waste-collection vehicles with biomethane - is the first one to be implemented in the whole of Germany. In addition we are exploiting measures to reduce greenhouse gases and thereby contribute further to protecting the environment.

Europäische Rechtsvorgaben und Auswirkungen auf die Bioabfallwirtschaft in Deutschland

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
© Witzenhausen-Institut für Abfall, Umwelt und Energie GmbH (11/2025)
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.
