Canon is working hard to reduce the amount of waste it generates. Efforts include increasing recycling through sorting and collection and minimizing initial waste generation. In particular, we have sought to determine which factors most significantly affect waste generation for each division and each production process. Based on these findings, we have implemented a number of ongoing initiatives to curb waste generation.
Total waste generation in 2017 amounted to 101,879 tons. The increase compared with 2016 was minimal despite the addition of Canon Medical Systems and business expansion. Waste generated per unit of sales fell to 2.45 t/100 million Yen, due to waste-reduction initiatives across sites.
Canon actively works to reduce the amount of waste originating from its operations and to reuse or recycle waste where possible, appropriately disposing of any waste that can be neither reused nor recycled in accordance with the law. Our various operational sites employ a range of in-house recycling schemes, including reprocessing waste plastic from injection molding or recycling it for other items.
Even in the case of waste that must be sent outside the company, we make sure it does not enter landfills*. Rather, we contract with companies that reprocess waste into materials. In 2017, contracted companies processed 98,999 tons of waste from Canon back into materials.
Canon assesses locations to confirm available water intake volume before establishing operational sites and facilities. We use the AQUEDUCT water-risk mapping tool provided by the World Resources Institute* for quantitative evaluation and reconfirmation of water risk in regions where production sites are located. The results of our evaluations show that no regions where Canon has production sites are considered to be extremely high risk.
In 2017, although the addition of Canon Medical Systems to the Canon Group and business expansion led to higher water usage, increases were minimized by raising water-usage efficiency at sites. Total water usage was 9,706 TCM* and water usage per unit of sales fell to 0.24 TCM/100 million Yen.
Canon collects water data by intake source (public water system, industrial water system, or groundwater) and manages water resources carefully so as not to exceed intake limits for the different regions in which it operates. We also set and manage targets for the volume of water used in production, and constantly strive to reduce water usage by improving production processes and raising water-usage efficiency at each operational site.
