Regenerative Energie
Whether the treatment and sorting facility for metal recycling is right next to a waste incineration plant, or whether this is done at the treatment facility of a dedicated company, is a business decision that has to be taken by each incineration plant individually. Systemically this is of lower priority, although the additional costs for transport will have to be taken into consideration in the climate Balance.
The mechanical plants are generating larger volumes, which are, however, of a considerably lower quality.
The systemic comparisons do not currently take all aspects sufficiently into consideration, so that many assertions do not stand up to a critical examination. The evaluation process, however, will be developed further over the next few years.
Even in mechanical treatment plants a separation of metals and rare earths is only possible to a basic extent. A truly single variety separation can only be achieved through metallurgical processes for which there is only a limited number of kilns in Europe.
For economical reasons, only a narrow treatment depth is sensible. Only when certain metals become considerably more scarce and their prices increase, will the scope of mechanical and metallurgical treatment rise.
It is crucial that the metals are not diffusely scattered during the disposal process.
A conclusive statement cannot currently be made, because the issue should probably be analysed in a more complex and differentiated way as is being done in some of the current publications.
Through further innovations, technological developments and rising profits, the Recycling of metal will be increased in all disposal processes, which will be of benefit for all involved and for all targets that are associated with metal recycling.

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.
Vom Gärrest zum hochwertigen Gärprodukt - eine Einführung

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.
