Kawasaki Industrial Park Tries to Achieve Zero Emissions

In 2002, the city of Kawasaki, which is recognized by the Ministry of Economy, Trade, and Industry as an “Eco-Town” and is working to develop an advanced environmentally conscious town, opened the “Kawasaki Zero Emission Industrial Park” in Mizue Town, Kawasaki Ward, Kawasaki City. The said park serves as a model facility for an eco-town. At this industrial park, the environmental impact of business activities is minimized by mitigating emissions and by-products, reusing and recycling them, and recycling energy.

The industrial park consists of 13 companies and facilities, such as paper mills, plating plants, ironworks, and refrigerated warehouses. Each company conducts its business with a transparent fundamental environmental policy. For example, Coalex San-ei Co., Ltd., a paper manufacturer, is the world’s first zero-emission paper manufacturing plant that produces toilet paper from 100% recycled paper. In addition, Sanko Seiko, which performs plating and other surface treatments, has installed a circulation system to prevent toxic chemicals from being discharged from the plant. As described above, each of the companies in the industrial park is working to achieve zero emissions individually. In addition to collaborating with neighboring companies, such as by jointly receiving surplus power, they are also cooperating with neighboring facilities, such as steelworks outside the industrial park, to effectively control emissions.

They are also actively working to reduce waste generated within the company. For example, the water used in the housing complex is recycled to reduce the load on wastewater treatment facilities. Incinerator ash and kitchen waste generated at the plants are reused as raw materials for cement and as fertilizer to reduce waste. The recycling system built at the industrial park is being used to achieve zero emissions throughout the region. In addition, the city accepts visitors from Southeast Asia and other parts of the world to visit industrial parks. Through these and other activities, the city will share the knowledge it has acquired about recycling to society.
