  13. In order to reduce the ecological impact of manufacturing, it is necessary to minimize the environmental burden of each part of the system. We have developed a new computerized simulation method for assessing the environmental impact of proposed new products and manufacturing processes. Inputs to the simulator include environmental loads, and product and facility information. The materials and energy which are input to and output from the system under analysis are measured in "Ecounits", an index which represents the total environmental burden of the resources used and system outputs. The output from the simulator allows calculation of the predicted increment in ecounits caused by operation of the system. During tests of the simulator, the environmental impact of a hypothetical factory producing mechanical components was predicted, and the simulation method was shown to provide realistic and useful data.

  13. The aim of this study is to investigate material and chemical recycling methods of polymer based products wastes. There are many kinds of polymer based products, for example, plastics, synthetic fibers, synthetic rubbers. And these products are made from many kinds polymers also. These products are very light, bulky and not decompose in natural condition. So, there are many problems to treat these polymer based products wastes. In this research, we are studing on (1) developent of material recycling technology of commodity platics and (2) developent of chemical recyclable polymers.
