2. Waste Reduction Policy
Main MSW Problems in Japan ① Growing Environmental Impact ② Strained Landfill Capacity ③ High Waste Disposal Cost Waste Reduction

Hierarchy of Waste Management
① Reduce (Source Reduction) ② Reuse (Reusing) ③ Recycle (Material Recycling) ④ Thermal Recovery ⑤ Disposal

What are not visualized ?
■garbage itself ■Information on the waste • Environmental impact • Costs for Administration and Citizen • Recyclability of garbage

Effect of Paid Collection System in Japan
1. Good reduction effect achieved both on disposal waste and on household waste 2. Reduction effects become better as fee level increase 3. Rebound trend has not been observed and reduction trend continues

5. Reconfirm the Importance of 3R
■Trend of MSW Reduction has continued, ■Consciousness of 3R has taken root in Japan But, Promotion for More 3R is ‘Must’ Make the Most Use of Visualization Measures ■Zero Waste Strategy is useful for the Visualization of Municipal Waste Reduction Goal
