The volume of waste generated in 2010 increased by 1.6 percent (65 tons) compared with 2009, but was 69.3 percent less than in 2003, meeting our goal of a 60 percent reduction. This achievement is attributable to successful efforts to concentrate and thus reduce the volume of waste liquid (waste alkalis) from highly active substances at the Fujieda plant, which had been increasing sharply for several years.

The cause of the increase in the volume of waste generated compared with 2009 was that the volume generated exceeded the reduction of waste through concentration. Initiatives to raise the efficiency of waste disposal included establishing a dual-route system of recycling and consignment to waste disposal contractors for flammable waste oil, and switching to nearby waste disposal companies. Chugai is also conducting verification at contractors' disposal sites and sharing information such as disposal costs and the conditions at contractors.

On the other hand, the volume of landfilled waste increased by 6 tons due to an increase in infectious and pharmaceutical waste. However, landfilled waste was down 81.2 percent from the 2003 level, meeting the Chugai Group's goal of an 80 percent reduction.
