The Hitachi has positioned the conservation of resources as one of the three pillars of its environmental vision. We are working on measures for preserving the Earth's environment and preventing resource depletion through the recycling of our products once they are no longer used.
The Hitachi is striving to improve its products through assessments of designs for the environment that are based on resource conservation, long-term usability, recycling, and ease of dismantling/disposal. We are also using product functionality and service life as well as the amount of resources in recycling and defining recycling efficiency as a guide to the improvement factor.
In order to comply with the 2001 Home Appliance Recycling Law, Hitachi has taken part in cooperative efforts by five companies*1 in the same industry while recycling air conditioners, televisions, refrigerators, and washing machines at 18 recycling plants nationwide. In fiscal 2014, we reused and recycled around 60,000 tonnes of the roughly 68,000 tonnes of end-of-life products we collected.
Today we are building on our know-how in recycling home appliances by creating a recycling network and expanding collection and recycling programs to include IT products like personal computers, servers, and communication equipment; industrial equipment including pumps, motors, distribution boards, transformers, refrigeration equipment, and machine tools; and industrial air conditioners and medical equipment. In fiscal 2014, we reused and recycled around 12,000 tonnes of the roughly 13,000 tonnes of the end-of-life IT products, industrial equipment, and other items we collected.
Innovated high functional materials that support energy and resource conservation are essential to creating a low-carbon society. Establishing technologies and schemes for recycling these materials can help secure stable access to materials, cut manufacturing costs, and reduce the environmental burden. With an eye on recycling material resources, the Hitachi is promoting efforts related to the recycling of rare-earth magnets, copper wire, amorphous transformers, and fiber-reinforced plastics.
Magnets that use rare-earth metals, which are even more scarce than rare metals, produce a powerful magnetic field, which is why they are widely used in energy-saving, high-tech products. More stable procurement of these materials is required because of their uneven distribution and limited availability. With support and grants from the Ministry of Economy, Trade and Industry and the New Energy and Industrial Technology Development Organization (NEDO), the Hitachi has been developing technology for separating and recovering rare-earth magnets from end-of-life products since FY 2009. In October 2013, Hitachi received the "Rare Metal Recycling Award" sponsored by the Japan Environmental Management Association for Industry. The award was given in recognition of the technology developed to separate rare-earth magnets from hard disk drives and air conditioner compressors.
The Hitachi is involved in cutting the amount of industrial waste and valuable materials that are produced as unwanted materials during manufacturing activities and in the recycling and reuse of such materials. The following links offer some examples at different locations within the group. Since fiscal 2011, we have implemented an Eco-Factories & Offices Select certification program for locations that show a high level of environmental consciousness.
