Case Study of the Day: Waste Management Efforts in Kamikatsu Municipality: Sustainable Waste Reduction and Recycling

Introduction

Kamikatsu is a small town located in Tokushima Prefecture, Japan. Like many other regions in the country, it faced a waste management crisis during the period of rapid economic growth. Between 1960 and 1980, waste volume skyrocketed from 8.9 million tons to 43.9 million tons, necessitating a reevaluation of waste management practices.

Challenges and Goals

The municipality of Kamikatsu recognized the environmental and health risks associated with incineration and decided to take a different approach to waste management. The key goals were to minimize waste generation, promote recycling and reusing of materials, and ultimately achieve zero waste.

Strategies and Initiatives

• Source Separation: Kamikatsu implemented a rigorous source separation system, requiring residents to sort their waste into 45 different categories. This meticulous separation process enabled efficient recycling and reduced contamination.
• Recycling Center: The municipality established a comprehensive recycling center, equipped with various facilities to process and sort recyclable materials effectively. The center served as a central hub for waste management activities, providing education and support to residents.
• Composting: Kamikatsu promoted composting as a means to handle organic waste. By encouraging residents to compost at home and facilitating community composting initiatives, organic waste was converted into valuable fertilizer for local farms.
• Reuse and Repair: The municipality encouraged the reuse and repair of items through the establishment of a “kuru-kuru” shop, where residents could donate and acquire second-hand goods. This initiative aimed to reduce unnecessary consumption and prolong the lifespan of products.
• Education and Awareness: Kamikatsu invested in extensive educational programs and awareness campaigns to foster a culture of waste reduction and recycling. Workshops, seminars, and community events were organized to engage residents and impart knowledge about sustainable waste management practices.
