抄録

In this experiment, the manufactured RDF made from combustible wastes was carbonized to develop new uses of RDF. Carbonization has been applicable to lumber and coal as an important method of making refining fuels.<BR>The following results were obtained.<BR>The weight of the carbonized product changed to 1/3 of the weight of RDF and 1/8-4/6 of that of the original waste that was originally RDF material. Another effect of carbonization was, 61% of chlorine was decreased. While trace elements which are necessary for the growth of plants are contained in the carbonized product, the content and the leaching amount of the toxic substance are so small, the carbonized product can be used as a soil improvement material.<BR>To reduce the chlorine content, the carbonized product was washed. After washing with hot water (80°C) and steam (115°C), more than 90% of the chlorine content in RDF was removed.<BR>From this experiment, it became clear that there are three advantages in the carbonization of RDF. Firstly, an improvement in transport efficiency by a decrease in the weight of waste and RDF. Secondly, a decrease in chlorine content, which is a very important factor when carbonized product are used for fuel. Thirdly the carbonized product can be used as a soil improvement material.
