日本城市垃圾的回收利用已引起人们的重视，并建立了一些实用的回收利用体系。介绍了日本城市垃圾处理方法的发展趋势.垃圾是一种适合堆肥的材料，因此，在过去的十年里，已经建造了许多堆肥厂。然而，由于建设和运营成本高、城市垃圾质量变化、塑料污染、恶臭废气处理不当等原因，利用垃圾生产堆肥的热潮正在降温。东京都的大型堆肥厂的特点和问题将成为大城市堆肥设施的典型。目前，一种小型家庭堆肥机在当地特别流行。一些地方政府制定了补贴制度，以促进每家每户使用这种堆肥机。地方政府推广的目的是减少每个家庭的垃圾处理量。有两种类型的堆肥。一种是简单的塑料箱型容器，放置在户外。另一种是新型电动式，配有搅拌、加热和添加膨胀剂，以加快堆肥反应速度。这个电动的也是在户外操作的。虽然堆肥机需要大量改进以进一步推广，但这种趋势将成为减轻地方政府废物处理费用负担的一种可能性。
Recycling of municipal wastes has been attracting attention and some practical recycling system has been established in Japan. The trend in disposal methods of municipal wastes in Japan will he explained. The garbage is an appropriate material for composting and thus, many composting plants have been constructed for the past ten years. The fever of the compost production by using garbage, however, is cooling down, mainly because of high construction and operation costs, quality change of municipal waste, contamination of plastics, ill-treatment of malodorous exhaust gas, etc. Characteristics and problems of a large-scale composting plant at Tokyo Metropolitan Government will be a typical example of the big city composting facility.At present, a small-scale home composter is getting popular especially in local areas. Some local governments prepare a subsidy system to promote the usage of such a composter at each house. The aim of this promotion by local governments is to reduce the amount of garbage disposed from each house.There are two types of composter. One is a simple plastic bin-type container which is placed in the outdoors. Another one is a new electric type equipped with mixing, heating, and amended with bulking agent to accelerate composting reaction rate. This electric one is also operated outdoors. Although there is a need of a lot of modification of the composters for further proliferation, this trend will be one possibility to loose burden of the waste treatment expenses in local governments.
