1. We have investigated biogasification facilities for kitchen garbage and livestock excreta in Japan and Europe. The biogasification evaluation items which can evaluates quantitatively the effect of biogasification for reduction of the environmental burden and the restraint of the natural resource consumption were developed.2. At three biogasification facilities for kitchen garbage in Hokkaido, we have continuously monitored the volume of biogas, concentrations of methane and carbon dioxide in the biogas, the odor from the facilities, concentrations of BOD, COD, SS, total nitrogen, and coliform bacteria count in liquid residuum and treated water, all of which is the component of the biogasification evaluation item. The methane concentration in the biogas, which varied according to the facilities, was about from 55 to 60 %. The amount of methane generated from one ton of kitchen garbage was about from 80 to 100 m^3. There were the differences in the level of odor and water pollutants e … More mitted from the facilities as various deodorizing and wastewater-treatment equipments were adopted. However, the amount of biogas from 1 ton of kitchen garbage and concentrations of methane and carbon dioxide in biogas, at each facility did not vary much across the ages. Liquid residuum was properly processed at all of the three facilities, thus their treated waste water amply fulfilled the national standard of discharge water.3. The amount of methane generated from kitchen garbage varied vastly by the quality of garbage. Thus we concluded that the cooperation from the residents to separately discharge the kitchen waste is indispensable in order to improve the efficiency of biogasification.4. We have developed the materials and manufacturing method of the polymer membrane that can separate methane and carbon dioxide. Therefore, we have obtained some fundamental information to practically apply the methane concentrating device that applies the membrane to control the methane level in the biogas to an optimal magnitude according to the intended end-usages.

1。我们已经投资了日本和欧洲的厨房垃圾和牲畜排泄物的生物估计设施。可以定量评估生物剂对减少环境燃烧和自然资源消费限制的影响的生物估计评估项目。2。在北海道的厨房垃圾的三个沼气化设施上，我们不断监测沼气中沼气的体积，甲烷浓度和二氧化碳的浓度，设施的气味，BOD，COD，COD，SS，SS，SS，总氮气，总氮和结肠菌细菌的浓度以及液体残留物中的数量以及对液体的评估。沼气中的甲烷浓度根据设施而变化，大约为55％至60％。一吨厨房垃圾产生的甲烷数量约为80至100 m^3。由于采用了各种除臭和废水处理设备，因此气味和水污染物的水平存在差异。但是，在每个工厂中，从1吨厨房垃圾中的沼气数量以及沼气中的甲烷和二氧化碳的浓度在整个时代的变化不大。在这三个设施中的所有设施中，都对液体残留物进行了适当的处理，因此它们经过处理的废水充分满足了全国排水水标准。3。厨房垃圾产生的甲烷量因垃圾质量而异。我们得出的结论是，居民与单独排放厨房废物的合作是必不可少的，以提高生物化的效率。4。我们已经开发了可以分离甲烷和二氧化碳的聚合物膜的材料和制造方法。因此，我们已经获得了一些基本信息，以实际应用甲烷浓缩装置，该甲烷浓缩装置将膜应用于沼气中的甲烷水平，根据预期的最终说明。较少的
