1. MSW in Japan

• Definition for MSW in Japan • Features of Waste Management in Japan Many Incinerators Strained Landfill Capacity Many Trash Items for Source Separation Small MSW Volume (g/capita/day) Low Recycling Rates

2

Definition for MSW in Japan

• MSW: Waste excepting Industrial Wastes • Industrial Wastes include C & D Waste ■ Japanese municipalities do not deal with C & D ■Australian municipalities do deal with C & D

Many Trash Items for Source Separation

<Standard Case> Garbage Items ・Burnable Garbage ・Non-Burnable Garbage ・Large Trash ・Harmful Garbage Recyclable Items ・Used Paper ・Cloth ・Glass Bottles ・Cans ・Spray Cans ・Metals ・PET Bottles ・Other Plastics

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

3. Visualization for MSW Reduction

<Relation between Visualization and MSW Reduction>

Visualization Non-visualization

Decrease Increase

What are not visualized ?

■garbage itself ■Information on the waste • Environmental impact • Costs for Administration and Citizen • Recyclability of garbage

The Process Citizens Act for Waste Reduction

Recognition Lag

Visualization Recognition Action Lag

Opportunity Promotion Incentive Action

Visualization of Garbage Itself

■Introduction of Transparent Garbage Bag <Effect> Improvement of Source Separation Several Percent of Garbage Reduction ■ Introduction of Door-to-Door Collection System <Effect> Improvement of Source Separation Several Percent of Garbage Reduction

26

Provision of Opportunity for Waste Reduction

■Education and Enlightenment ◎ Provision of Original Cloth Bags ◎ Provision of Kitchen Garbage Draining Goods ◎ Provision of Paper Bags for “Mixed Paper” Collection ・Mixed Paper account for 40% of Used Paper in Burnable Garbage

Economic Incentives for Waste Reduction

◎ subsidy for buying composting appliances ◎ subsidy for used paper collection activities by citizen’s groups ◎Paid Collection System

4. Paid Collection System The Best Visualization and Incentive Program

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

33

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
