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.

This project aims at developing the experimental methods to evaluate atmospheric lifetime and degradation products of chemical species mainly as the environmental acceptability study of the developing alternative refrigerants such as fluorinated ethers. The removal processes through photolysis, dissolution into water droplets as clouds, degradation on solid particles as aerosols are investigated.

13. This study aims to develop a new method for the sequestering of CO₂ in deep sea as CO₂ hydrate. Under the temperature and pressure conditions of deep sea, the mixture of CO₂ and water forms the crystalline molecular complex, called CO₂ hydrate clathrate. CO₂ molecules is enclosed within the lattice formed by water molecules, which are strongly hydrogen bonded with each other. As the density of CO₂ hydrate is higher than that of sea water, CO₂ hydrate would be sequestered in deep sea. To investigate the feasibility of deep sea CO₂ sequestering, it is necessary to study the physical properties of CO₂ hydrate. The object of this study are to investigate the formation and dissociation processes of CO₂ hydrate and its physical properties.
