A Basic Study of Establishment of Recycling Method And a Investigation of the Status Quo of Packaging Wastes in Wholesale Markets.

对批发市场进行问卷调查，掌握垃圾的发生和处置情况。回收率为86%。回收率相对较高的是一个瓦楞纸箱，一个膨胀的聚苯乙烯容器和一个调色板。发泡聚苯乙烯容器的回收率为69%。大多数的回收方法是将其熔化固化后，运到国外作为再生塑料使用。然而，由于供过于求，其销售价格非常便宜且不稳定。为此，研究了膨胀聚苯乙烯的热、化学减容方法。另一方面，作为一种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。我们调查了一种制造燃料油的植物的现状。结果，我们发现在批发市场上工作的工厂只有一家，而且问题很多，而且很难使这家工厂可行。所以我们测量了更高的热值和粘度并讨论了可能性和方向。在目前的情况下，我们正在用添加剂在较低温度下制造燃料油，并在锅炉的燃烧器上进行实验。在未来，我们将计划开发最合适的方法来制造油和燃烧植物。

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.
