Japan “Resource Recycling Technology and System Award” for Canon Green Calculator


Oct 19, 2010


“Resource recycling technology and system award” is established by Clean Japan Center (CJC) in 1975. The purpose of this award is to construct recycling-oriented social system. CJC grants the award to company and organization in Japan who contribute excellent technological development related to reduction, recycle and reuse of waste material. In this connection, the above 経済産業省産業技術環境局長賞 Ministry of Economy, Trade and Industry Technology Environmental head award has been granted to both Canon Ecology Industry Inc (Ibaraki Prefecture) and Canon Electronic Business Machines (H.K.) Co.,Ltd in using 100% Recycle Plastic for Canon Green Calculator Outer Case.


Until now in recycling the plastic of used product, it is indispensable to focus on the characteristic of the resin material and in order to maintain quality assurance, there was a problem to face the rising cost of recycle resin and the limit of combination rate (about 30%).


The two group affiliated companies have collaborated and performed the processing of recycle resin, reexamination of the physical-properties standard and usage development. As a result, it realizes the 100% recycle of collected copiers’ exterior to the outer case of calculator.





The characteristics of the product are:


  1. Utilized the recycle plastic in calculator parts which used to have the problem of resistance-to-flame grade, tone and appearance problem due to exterior parts application difficulty. (Green calculator has accumulated shipment of 910,000units from 2006 to 2009 year end)
  2. By the sole material processing technology, it actualizes low environmental impact from virgin material and low cost by resource circulation.
  3. With the collaboration of the group affiliated companies, it develops the closed recycling of raw material and expands the usage range of recycle resin material.
  4. The rationalization and high efficiency of plastic processing domestically in Japan has attained a maximum of 50% cost reduction. Comparing to the virgin material (HIPS) which is being used conventionally in Hong Kong, it can achieve a maximum 20% cost down. Moreover, in applying the sole processing technique of processing recycle resin, it enables 100% use of recycle material which contributes to social construction of resource recycling internationally.
