We sent wholesale markets questionnaires survey to grasp the state of occurrence and disposal of garbage. The rate of collection was 86%. Grabage which had relatively high rate of recycling was a corrugated carton, a expanded polystylene container and a palette. The recycling rate of expannded polystirene container was 69%. Most of method of recycle was that after it is melted and solidified, it is carried overseas and used as recycling plastics. However, its sale price is very cheap and instability, becase of over supply. So, we studied the thermally and chemically method reducing volume of expanded polystirene. On the other hand, as a method of recycling expanded polystirene, there is one that tharmally degrade and create a fuel oil. We investigated the status quo with a plant creating a fuel oil. As a result, we found that plant which was working in a wholesale market was only one and it had many problems, also it is difficult to make this plant practicable. So we measured higher calorific value and viscosity and we discussed with a possibility and derection.under status quo, we are making experiment on fuel oil created on lower temperature by using an additive and on a boiler's burner. In the future, we will plan to develop the most suitable method creating oil and burning plant.

我们对批发市场进行问卷调查，掌握垃圾的发生和处理状况。收集率为86%。回收利用率较高的草类为瓦楞纸箱、膨胀聚乙烯容器和托盘。聚苯乙烯发泡容器回收率为69%。回收利用的方法大多是将其熔融固化后，运到国外作为再生塑料使用。但由于供过于求，其销售价格非常低廉且不稳定.为此，我们研究了热法和化学法降低发泡聚苯乙烯的体积。另一方面，作为回收膨胀聚苯乙烯的方法，有一种方法是热降解并产生燃料油。我们调查了一家生产燃料油的工厂的现状。结果，我们发现，在批发市场工作的工厂只有一个，它有很多问题，而且很难使这种工厂切实可行。为此，我们测定了高热值、高粘度的燃料油，并对其可能性和方向进行了探讨。针对目前的现状，我们正在进行添加剂低温制取燃料油的试验，并在锅炉燃烧器上进行试验。今后，我们将计划开发最适合的方法来制造石油和燃烧植物。
