外文摘要：In order to get more detailed information for better decision making in future biogenic waste treatment， different processes to treat biogenic wastes in plants with a treating capacity of 10，000 tons of organic household wastes per year were compared。 The comparison included life cycle assessments as well as economic considerations for different treating methods。 Measurements on compost plants showed that methane emissions are higher than estimated so far。 With the tools ECOINDICATOR and UBP anaerobic digestion shows to be advantageous as compared to composting， incineration or combination of digestion and composting， mainly because of a better energy balance。 In fully enclosed， professional treatment plants， the specific biotechnological treatment costs are in the range of about 150。-sFr/ton for aerobic， anaerobic and combined technologies。 It can be concluded， that anaerobic processes will become considerably more important in the future mainly for ecological reasons。
