2 Consumers Processing Mercury Deliver Collection Can Collect Spent Button Batteries (Waste in Collection Cans) Report Instruct Transportation Entrust Transportation Register via Internet or FAX Entrust Disposal Voluntary Scheme of Button Battery Collection by BAJ (Started in 2009) FDK Sanyo Schick SII Sony Toshiba Panasonic Hitachi Varta Mitsubishi Siemens Starkey Nexcell Battery Association of Japan (BAJ) Material Maker Sell Valuables Reuse Flow of Spent Products Money Flow Information Flow Approval by the Minister of The Environment 2 Participating Companies (BAJ Members) Secretariat (Button Battery Collection Center) Sponsor Website, Call Center Receive Spent Button Batteries from Consumers Flow of Other Goods Entrustment Entrust Waste Disposal Report Collection Outlets (Cooperative Shops) Transportation (Couriers) Waste Disposal (Recycler) Transport Spent Button Batteries (Waste in Collection Cans) Nothing Landfilled

3 The Results of FY2010: Cooperative Shops by Category The Number of Cooperative Shops (Cumulative Basis) 3 10,492 Big Growth ! 8,237 The number of collection outlets increased by 2,255 up to 10,492. In particular DIY and grocery showed big growth.

7 Sampling Research: Mixture Ratio by Battery 7 Sampling Research Total Collection Note: The mixture ratio of total collection is a weighted average by using the results of sampling research. The mixture ratio changes depending on the category of shops. Grocery and DIY have relatively high ratio of SR battery. The weighted average shows PR accounts for 69%, LR 22%, and SR 9%.
