Today, many environmental problems are being observed by a lot of people, and waste management has become one of the most serious problems in Japan. In this paper, we analyzed industial wastes coming from both livestock and marine products in Japan.Much residue has been found in slaughterhouses or meat factories. Some factories use this residue and process materials for feed and fertilizer. These factories are called “rendering plants”.There are about 150 rendering plants in this country, and most of them are medium or small-sized ones. Recently, Japanese agriculture is on the decline, and it has become difficult to supply a sufficient amount of residue to the rendering plants. The locations of this business are dispersed around the country, making it difficult to transport the residue a long distance because it is often decayed. Furthermore, the odor remains a serious problem for this business.As the distribution system of the rendering business is vague, it is neccessary to grasp and plan how to use and remove these resources for a better future.
