Resource Index Data Collection Methods and Rationale

(Updated on August 22, 2014)

The resource index is calculated as follows:
(1) Volume of waste landfilled from sites + (2) Product resource input – (3) Volume of reused/recycled materials – (4) Volume of resource recovery from end-of-life products

(1) Volume of waste landfilled from sites

Of the waste generated at sites, the weight sent to landfill.


(2) Product resource input

Total volume of resources used in products, accessories, manuals and packaging materials. Total weight of products shipped is used as a substitute.


(3) Volume of reused/recycled materials

Total volume of reused/recycled materials and vegetable-based plastics used for products, accessories, manuals and packaging


(4) Volume of resource recovery from end-of-life products

Volume of products collected from recycling multiplied by the reused/recycled ratio.
Volume of products collected from recycling is the weight of recycled products in Japan/East Asia, Europe, North America, Pan Asia, and Latin America.
Some amounts calculated based on the recycling expenses are included.
The reused/recycled ratio is the volume reused/recycled compared with the total volume collected. The amount of collected end-of-life products is substituted under the current situation.
