Only eleven (0.2%) of the 5,507 Brazilian municipalities have C&D waste recycling centres. Thirteen centres (seven in operation, one restarting its operation and five have shut down) are stationary plants and recycle part of the C&D waste produced in local communities. It can, therefore, be concluded that a large part of this waste is not recycled in Brazil. Nonetheless, this situation is changing. Since the publication of CONAMA (Brazilian Environmental Protection Agency) Resolution no. 307 in 2002, all Brazilian local governments are obliged to prepare and adopt strategies for sustainable management of C&D waste (MMA, 2002). In the justifications for this resolution, mention was made of the feasibility of the production and use of C&D waste materials. However, there has been relatively little research in Brazil to prove the technical and economic viability of C&D waste recycling centres.
There are very few construction and demolition (C&D) waste recycling centres in Brazil. Data relating to C&D waste management and recycling in Brazil were collected and analysed to encourage the building and operation of new units. Based on the results of this analysis, a conceptual model was proposed to perform feasibility studies of future C&D waste recycling centres. Applying this model to verify the feasibility of private recycling centres, negative results show that C&D waste recycling centres in current market conditions in Brazil are not financially feasible if based solely on revenue from the sale of processed products. A case study for the city of Rio de Janeiro is discussed. The conceptual model, results of its applications in the city of Rio de Janeiro and their analysis can strongly support public authorities and private initiatives in their decision-making about investments in waste recycling centres in Brazil and in other developing countries.

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.
