Abstract: In newly industrialized countries and Third World countries, biogenic waste frequently constitutes a threat to ground water due to its being contaminated with bacteria and germs. In order to decontaminate such biogenic waste, one or more closable sanitizing chambers are fitted with open containers that are filled with the biogenic waste. The sanitizing chambers are closed, and hot waste gases (80° C. to 140° C.) are guided through the sanitizing chambers until germs and bacteria in the biogenic waste are killed. The sanitizing of biogenic waste eliminates the waste as a source of diseases and ground water contamination. The invention is suitable for decentralized locations, for example, in Third World countries or newly industrialized countries or places with stand-alone grids. The invention can have either a stationary or a mobile design.

Abstract: A product gas is generated from carbonaceous raw materials by allothermic gasification in a reactor. The reactor includes a pressure-charged reformer reactor for gasification of the carbonaceous raw materials, a feed line for feeding carbonaceous raw materials and ancillary materials for gasification into the reformer reactor, a combustion chamber thermally coupled to the reformer reactor for generating the heat required for the allothermic gasification, and a pneumatic conveyor device for removing particulate gasification residue and raw gas from the reformer reactor and for feeding the particulate gasification residue into the combustion chamber. A gas filter separates out the particulate gasification residue from the raw gas. The gas filter has a discharge line for product gas and discharge line for solid particles. A pressure lock has a high-pressure side and a low-pressure side. The gas filter and the pressure lock are separate components.
