Looking to the future: by tungsten 100% recycled Toyota motor + sumitomo electric construction of recycling system
To remove material risk by recycling
As for sumitomo electric group one of tungsten recycling business achievements, in 2013, a landmark thing happened.In the field of superhard tools, sumitomo electric industries and as a user of Toyota motor corporation (hereinafter referred to as the "Toyota") to build the domestic recycling systems are highly praise, and general corporate environmental management industry association in Japan hosted by the "resource recycling technology and system recognition" conference, won the award of rare metal recycling.Superhard tools, including Toyota motor is considered to be one of the competitive source of Japanese auto makers.Its stable quality and price has been supporting the development of automobile industry.But in Japan, as a feedstock for superhard tools of tungsten is a kind of alternative low resources, dependence on imports, this for auto makers as the user is also a kind of risk.At Toyota is mainly responsible for preparation of superhard tools today to ms Li Li beauty, also expressed great concern about how to ensure that the material of this.It is said that at that time is sumitomo electric group first proposed the idea of hope cooperation to construct a system of recycling.
"Sumitomo electric group is the company's main partner, its head of cooperation scheme of constructing recycle system are put forward.It was around 2011.Sumitomo electric开发出了回收利用新技术（前述湿式氧化法），并可使用该技术从切屑中回收高纯度钨加以利用，我们对这些成果深感兴趣，认为是充满魅力的提案。有相当分量的切屑都无法回收，这是住友电工集团作业现场的课题之一。而若是本公司，或许可以回收一定分量。这一点便是共同构建回收利用系统的契机。在此之前，本公司都是将切屑全部卖掉，但考虑到回收利用可大幅降低材料风险与促进SDGs目标实现，我们开始与住友电工集团合作构建回收利用系统。”（今给黎女士）
Toyota motor by thoroughly "sorting"
Toyota to act quickly.Accurately grasp the social situation, quickly insight into the needs of the materials, equipment department began to mobilize factory, relevant departments such as production technology and environment, began to move.But the effect of recycling efforts have not immediate.Under such circumstances, the department for many lobbied the resonance of the employees and for approval.
"Building a recycling system of the sorting job caused a burden to the field staff.We patiently explained to internal related personnel 'overall economic advantage and the activity of social mission, finally won approval."(now give Li Nvshi)
Toyota and responsible for the recycling process after the sumitomo electric group cooperation to build up "in regenerative sorting method", this is especially impressive.Toyota factories to carry out the sorting operation.From "superhard tools" and "die" this classification, the hard part of fine classification (including cutting blade and bit chip), has carried on the thorough sorting.Then, as one of enterprise, and ahead of competing companies, cooperation with recycling industry to build up a "return to Japan's domestic recycling system".Finally achieved from the hard ware chip 100% recovery and utilization of tungsten in this outcome.
"Now, recycling system has been effectively used, and in a state of stable operation.In the future, in addition to the hard chip, we also plan to construct a system of waste recycling.In addition, we are looking forward to sumitomo electric group can further enhance ensures the economical efficiency of rare metal recycling technology, let outside of rare metals tungsten back to Japan."(now give Li Nvshi)
Sumitomo electric group, Toyota's looking forward to how to respond?It is the key to the future business expansion.
A challenge to the recycling of evolution and innovation
Cooperation with Toyota to build the "return to Japan's domestic recycling system", after the completion of sumitomo electric group, a series of measures about recycling began to big., including sumitomo electric group, Japan's domestic tungsten recycling business began to accelerate, but there is a certain distance from total recycling.In such cases, sumitomo electric group should take what action?Sumitomo electric常务董事、先进材料事业本部的部长佐桥稔之围绕今后的回收利用事业如是说道：
"Due to the development of joint materials chemical treatment method and NIRE company career in the United States, the group's business covers successfully from upstream raw materials (ore refining and chip) to as the final product of superhard tools, this is the group's advantage.Ore refining, the reliance on outside Japan mining hidden in a lot of risk.Therefore, must be based on the recycling, push hard alloy.At this point, the complete technical level is particularly important, that is, to maintain high quality at the same time, cut costs, etc.NIRE companies in the United States must establish recycling technology as soon as possible, the joint material must also be the pursuit of a higher level of technology.In the future under the current situation of the international situation is unclear, the importance of recycling self-evident.In addition, from the BCP (business continuity plan) point of view, there are also some risks.Now, as the superhard tools main products of the production of cutting blade outlets only Hokkaido.Shutdown losses caused by disasters is enormous.NIRE company has just set up, I'm working in as investors SCI company for some time, so there is quite a shrine.I was thinking if there is such a NIRE company, in addition to the production of tungsten trioxide (settlement3), I also consider to build a new cycle to produce tungsten carbide (WC), and the final product of the production system.This is my own dream."(zc bridge)
From sumitomo electric group began to develop "wet oxidation method" of the new technology and to promote recycling business, has been through a decade of years.Tungsten recycling development itself has been quietly, but recycling environment and people's consciousness has changed dramatically.Once the world "by recycling is good", now the world thinks "recycling is inevitable.And SDGs viewpoint has been widely spread all over the world, around us there are many people begin to emphasis on recycling and put into practice in your life.In this context, to ensure that scarce resources of tungsten, sumitomo electric group developed a new recycling technology and build up the system, the results are innovative.These are now in advance, and to explore the new era of recycling the ideal form, we have launched a challenge to further evolution and innovation.
