Wollastonite-type glass ceramics were prepared by milling and firing at various temperatures using an automobile waste glass and waste shell as starting materials. Powder mixture ground by disk-type ball mill for 3 hours was pressed into a disk. The pressed specimen was fired at $850^{\circ}C$,$950^{\circ}C$ and $1050^{\circ}C$ for 1 hour in air. From FE-SEM observation, with an increase of the firing temperature from $850^{\circ}C$ to $1050^{\circ}C$, whisker-type phase was grown to about 10 $\mu\textrm{m}$ in length. Specimen fired at $1050^{\circ}C$ showed the formation of well-crystallized whisker-type wollastonite grains and the highest compressive strength.

A steam Rankine cycle was considered to recover waste heat from the exhaust gas of an automobile. Conceptual design of a swash plate type expander was practiced to convert steam heat to shaft power. With the steam pressure and temperature of 35 bar and $300^{\circ}C$ at the expander inlet, respectively, the expander was estimated to produce the shaft power output of about 1.93 kW from the exhaust gas waste heat of 20 kW. The expander output increased linearly accordingly to the amount of exhaust gas waste heat in the range of from 10-40 kW, and the Rankine cycle efficiency was more or less constant at about 9.6% regardless of the waste heat amount.

Due to the urbanization, lots of people are living in cities. It is very convenient to live in the cities for the people but at the same time, the highly populated city has several environmental problems. During delivery process of large amount of municipal waste generated from the cities, the automobile emission and traffic jam have been occurred. The waste collection in the cities has been mainly done by using labour force and delivery truck. This is the conventional waste collection up to now. Recently, new technologies like automated waste collection system and capsule transportation have been introduced. Conventional waste collection mainly relied on the labour force and truck delivery does not need to invest a lot of money for the start-up. However, it requires to pay the operational cost both for the labour force and the truck delivery. On the contrary to this conventional waste collection, the automated waste collection and capsule transportation require high initial investment cost. However, the automated waste collection and capsule transportation can reduce significantly the pollutants emission, traffic jam by the waste trucks and actual waste collection cost per ton. In dealing with the waste collection in the cities, new waste collection technologies could be properly combined with the conventional waste collection for the effective municipal waste treatment.

Wastes such as shredder dust of disposed vehicles can be decomposed into low calorific flammable gases by Pyrolysis gasification. A stationary electric Power generation using an internal combustion engine fuelled with the waste-pyrolysis gas is an effective way to ease both waste management and energy saving issues. The waste-pyrolysis gas mainly consists of H$_2$, CO, $CO_2$ and $N_2$. The composition and heating value of the gas generated depend on the conversion process and the property of the initial waste. This research analyzed the characteristics of the combustion and the exhaust emissions in a premixed charge spark ignition engine fuelled with several kinds of model gases, which were selected to simulate the pyrolysis-gases of automobile shredder dusts. The influences of the heating value and composition of the fuel were analyzed parametrically. Furthermore, optical analyses of the combustion flame were made to study the influence of the fuel's inert gas on the flame propagation.

Differences in risk perception on major environmental issues between general public and environmental experts were investigated in this study. Questionnaire surveys were conducted to samples from general public and environmental experts during March and April, 2000. Total number of responses was 1,126 including 773 persons from general public and 353 experts. Risk perceptions on 26 environmental issues were related with the need to regulate each issue, controllability, experience, political views, interest in environmental problem, satisfaction of environment, severity of environmental pollution. There was statistically significant difference in risk perceptions between general public and experts. Overall, general public was likely to perceive risks associated with environmental problem, as well as social need to regulate these problems more than experts. The issues with high risk perception and need to regulate were 'automobile exhaust', 'industrial air pollution', ocean pollution by industrial waste and oil exhaust', 'air pollution by chemicals', 'surface water pollution by waste from household', 'industrial and hospital waste', 'surface water pollution by pesticide'and'sewage and food waste'. Consequently, it seems necessary to manage these issues, prior to others.

Chemical catalyst products are applied to various fields such as petrochemical process, air pollution prevention facility and automobile exhaust gas purifier. The domestic and overseas chemical catalyst market is increasing every year, and the amount of waste catalyst generated thereby is also increasing. Most of the used chemical catalyst products, such as desulfurized waste catalysts and automobile waste catalysts containing valuable metals are important recyclable resources from a substitute resource point of view. The recycling processes for recovering valuable metals have been commercialized through some urban mining companies, and SCR denitration catalysts have been recycled through some remanufacturing companies. In this paper, the amount of domestic production and recycling of major catalyst products have thus been investigated and analyzed so as to be used as basic data for establishing industrial support policy for recycling of used chemical catalyst products. Also tasks for promoting the recycling of used chemical catalyst products are suggested.

It has been known that there are large amount of nitric acid and valuable metals, copper in the plating waste solution of automobile wheel. As nitric acid and valuable metals are high price and toxic, they should be recovered for economics and environment. Plating waste was extracted with TBP diluted with kerosene. The concentration of nitric acid in aqueous phase was analyzed by titration method by NaOH solution (0.1~1.0N) and the amount of metals by ICP-MS and ICP-AES. The concentration of copper in plating waste were 76,850 mg/L. The concentration of nitric acid in plating waste was 1.02 M. After three step extraction was performed with 50% TBP, each organic phase was stripped three times with distilled water to obtain 48.1% of nitric acid. Purity of final nitric acid was over 99.9% by ICP analysis. After recovery of nitric acid, copper was extracted with various solvent extractors like PC 88A, D2EPHA, LIX 84 and ISE 106. Among these extractors, 92% of copper was recovered by ISE 106 after 1st extraction and 30% $H_2SO_4$ stripping. Copper ion was reduced with $N_2H_4$ to make metal powders, respectively.
