Regenerative Energie
Where are we? Where are we going? ……………………………….. The degradation of the earth continues. Man in his quest for survival and ever increasing affluence uses up more resources than what is available from the natural cycle on this planet and generates more waste than is necessary in the process of improvement. Resources are being wasted. Although often seen as an emotional statement the facts are there for all to see. Man is using far more than what the earth can offer or replenish.
Man in his quest for survival and affluence uses up more resources than what is available from the natural cycle and generates more waste than is necessary. In developing countries survival is a day to day concern. When one considers sustainability in relation to the state of the environment, there are many environmental areas that need to be assessed and addressed. In this paper waste is used as the prime indicator. It is acknowledged that waste is by no means the sole contributor. In South Africa, it is now six years after the Polokwane Declaration was signed. The main goal of this is the stabilization of waste generation, the reduction of waste disposed by 50% by 2012 and a plan for zero waste by 2022. It is four years after the world summit in Johannesburg where strategy formulation focused on people, prosperity and the planet. These are the three legs of sustainable development which relate to the environment, the economy and society. All three must be satisfied, however, there is often one or more that remain unsatisfied leading to unsustainable processes. Do we understand the real concepts of sustainable development? Are these being addressed by the three tiers of government in South Africa? Has the state of the environment improved since the events in 2000 and 2002? With the buy in of all three tiers of government and the buy in of society at large the goal of achieving sustainable development in South Africa is achievable. Humans can survive in harmony with natural 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.
