October is Reduce, Reuse, Recycle Month in Japan. Government agencies – the ministries of the Environment; Finance; Education, Culture, Sports, Science and Technology; Agriculture, Forestry and Fisheries; Economy, Trade and Industry; Land, Infrastructure, Transport and Tourism; and Consumer Affairs – come together to promote efforts to create a greater recycling-oriented society.
Closed loop recycling
Nissan supports Reduce, Reuse, Recycle Month and has a long-term commitment to creating a sustainable mobility society. Nissan builds cars from a 3R point of view, starting at the design, development and engineering phase, and considers the vehicle’s total life cycle for ease of recycling and scrapping of used cars.
Nissan also has focused on raising the usage rate of recycled materials in new vehicles since FY2011 as Part of the Nissan Green Program 2016, a mid-term environmental action plan. In particular, Nissan is promoting the “closed-loop recycling” method in which production remnants and collected Nissan products are recycled as parts materials and reused in similar products, all maintaining the high level of quality for which Nissan is known. Using this approach, materials can be used repeatedly, and CO2 emissions and other environmental impacts can be reduced.

Why does the use of recycled materials increase?
According to the World Resources Institute, mining and exploration sites currently in operation are in environmentally sensitive areas. Mineral mining requires large amounts of water, and one of the concerns is that the intensive processes can impact ground water and the surrounding environment. As demand for cars is expected to increase, the demand on resources and the price of materials also are expected to rise. So both the environmental impact of the materials used and the costs of purchasing new materials must be considered.
In order to continue to meet the transportation needs of customers and minimize the impact on the environment, Nissan will limit the use of virgin materials and promote saving resources by recycling and reusing materials. Nissan will increase the adoption rate of recycled materials for new cars which will be launched in Japan, US and Europe in 2016 to 25 percent (by weight) and to 70 percent in the long term to maintain the total amount of materials used in fiscal year 2050 at the level of fiscal year 2010.
To achieve this target, Nissan is promoting recycling resin, aluminum and iron to be reused as vehicle materials in the closed-loop recycling system.

Nissan’s recycling efforts
At Nissan, steel and aluminum remnants produced in the stamping process are collected and delivered to material manufacturers to be returned to the cycle for other materials production. Aluminum wheels collected from used vehicles are cleaned and recycled to produce other aluminum wheels.
Resin bumpers replaced and collected at dealers are recycled into bumpers for new vehicles in a recycling process at the Nissan Oppama Plant. In this process, bumpers are ground and paint film is peeled off at a lower cost than before without using chemicals. Resin parts recovered from used vehicles are recycled into parts for new cars using a technology to match colors.
