The Current State of Kawasaki City’s Eco-Town—The 2020s

The Current State of Kawasaki City’s Eco-Town—The 2020s Now that we have entered the 2020s, Kawasaki City’s Eco-Town has evolved further, with the introduction of renewable energy and the advancement of waste recycling technologies. In particular, the annual volume of recycled plastic has increased to approximately 50,000 tons, and this recycled plastic is being used to produce ammonia and hydrogen energy. This contributes to reducing CO2 emissions, and an increasing number of companies are participating in these initiatives. Showa Denko continues to refine its technology for producing ammonia from recycled plastic, achieving a 20% annual improvement in production efficiency. Additionally, the use of hydrogen energy is expanding; in particular, Toshiba Energy Systems & Solutions is strengthening the supply of hydrogen generated from waste to fuel cell vehicles and industrial fuel cells. Furthermore, Kawasaki City Eco-Town is conducting research and development on Carbon Capture, Utilization, and Storage (CCUS) technology. A pilot program is underway to capture CO2 generated during waste treatment and reuse it in industrial processes. This technology is attracting attention as an urban carbon cycle model through collaboration with chemical plants and power plants concentrated in Kawasaki’s coastal area. Furthermore, renewable energy sources such as solar and wind power form the core of the Eco-Town’s energy supply. Hitachi, Ltd. has installed large-scale solar power facilities that supply enough electricity to power 50,000 households annually. In the field of wind power, the Eco-Town is partnering with overseas companies such as Vestas to introduce more efficient power generation systems. As an advanced project linking urban waste management with energy circulation, Kawasaki City Eco-Town is attracting an increasing number of visitors from both Japan and abroad, and further participation from new technologies and companies is anticipated. In particular, efforts are being intensified toward the goal of reducing CO2 emissions by 50% by 2030, and Kawasaki City is further enhancing its presence as a model case for sustainable urban development.
