Material Balance

FY 2017/3

  • Note 1:Raw materials: Sum of product weight and waste emissions
  • Note 2:Air: For POPS (persistent organic pollutants) and HAP (hazardous air pollutants), substances subject to the PRTR Act are covered by the statistics.
  • Note 3:Recycling rate: The ratio of the weight of reused, material-recycled, and thermal-recycled items to the total weight of the collected IT devices
    Resource reuse rate: The ratio of the weight of materials that can be used as recycled products (reuse of parts) or resources (material recycling) to the total weight of the collected IT devices (as defined by the Law for the Promotion of Effective Utilization of Resources)
