Nitto Denko Group CSR & Annual Report 2011

29/40

CSR & Annual Report 201129Environmental Performance Data– Effective utilization of resources –Most of the industrial waste generated from production activity within the Nitto Denko Group consists of solid material and liquid waste. The solid waste mainly consists of log roll edges and off cuts from the production process whilst the liquid waste is comprised of etching and iodine waste and the like from the manufacture of electronics-related products. The solid waste is created in making adhesive tapes and optical products. Liquid waste is generated from the production of circuit boards and the like.As to the amount of industrial waste in 2010, the growth rate was almost the same as the increase in turnover on the previous year. In consequence of our implementing the effective utilization of industrial waste, mainly in domestic bases, the amount of marketable resources recovered from industrial waste increased over the previous year. Marketable resources are recyclable as fuels or materials and marketable. The effective utilization rate (the ratio of the amount of marketable resources to the total amount of industrial waste) of industrial waste increased by 2%.Adopting and implementing approaches that result in reusable waste is very important, but the Nitto Denko Group focuses on reducing the amount of industrial waste created. The generation of industrial waste stems from the inefficient use of resources. We will continue to focus on the development of production processes in which no industrial waste is created.025,00050,00075,000100,000125,000150,00013014015016017018019061,5502,95552,6921692010200562,6743,03213,28472,9653,03817,01956,7613,02343,53659,9462,84950,54576,22965,2733,1931631781771851682006200720082009(metric tons/year)(kg/million yen)(FY)Nitto Denko CorporationDomestic group companiesOverseas group companiesUnit generation05101520253015.028.022.024.626.620062007200820092010(%)(FY)Total and Unit Generation of Industrial Waste (consolidated)Effective Utilization Rate of Industrial Waste (consolidated)
