Regenerative Energie
SUMMARY:
Both an increasing demand in energy and the amount of municipal solid waste generated are problems encountered in developing countries as well as developed countries. One way out includes the use of solid waste as a source of energy. The paper investigates the potential of organic solid waste (OSW) for energy generation in Lusaka the Capital of Zambia. It was found that the unit generation rates for solid waste are 0.6, 0.5 and 0.4 kg per capita and day for low, medium and high-income residential areas respectively.
Solid waste is basically collected as a mixed stream. However, some separation at source for ferrous metal and paper is carried out. From previous waste characterisation studies, it was found that 40% of the mixed solid waste is of organic nature that can be used for anaerobic digestion. As for energy, it was found that about 46% of the population in Lusaka has access to electricity for cooking as well as for lighting. The rest of the population relies on charcoal, wood fuel and kerosene. The peri-urban case study area of Kanyama Compound is identified and discussed. Using its organic waste potential for biogas production, about 20% of the population without electricity in the Compound can benefit from the energy generated. Nevertheless, there is a need for source separation of OSW. As to funding arrangements, this project requires government subsidies since the direct beneficiaries from the energy point of view are poor people who cannot afford a project that calls for full cost recovery. The incentive for the government is that this project can reduce health and social expenses as well reduce impact on the environment. Although the National Energy Policy of 2005 supports energy generation from OSW, projects have not been implemented yet.

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

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.
