In the development stage, we design our vehicles to avoid using environmentally harmful substances in their construction and make them easier to recycle. Additionally, to reduce our use of nonrenewable resources, we give consideration to the use of recycled plastics, other recycled materials, and renewable bio-materials. We are also examining the possibility of recycling plastic parts from end-of-life vehicles and using this material for new vehicles, searching for ways to overcome the technical challenge of maintaining quality.
3R design activities
Outline of life cycle with the Note
Considering the recycling of end-of-life vehicles and reuse of parts, it is important that design be conducted with consideration of the 3Rs (reduce, reuse, recycle) during new vehicle development. We therefore prepared Design Guidelines to advance recycling design of new vehicles. These guidelines suggest areas for improvement and new ideas for design with consideration for the 3Rs.
- Recycling ease (recoverability rate)
- Ease of dismantling at the end-of-life stage (dismantling efficiency)
- Material identification markings for plastic parts (plastic part marking)
- Reduction of environment-impacting substances
Development process for 3R* design
Nissan received ISO 14001 certification for its product development process in fiscal 1998.
We have established targets for the recoverability rate, dismantling efficiency, plastic part marking, and reduction rate for environment-impacting substances in the development of new vehicles. We have also set clear criteria for the design stage, and are conducting management and evaluations of our progress in achieving these targets.
- *Reduce, reuse, recycle
Development of recycling simulation system
Nissan and Renault S.A. jointly developed OPERA, a system to simulate the recoverability rate and recycling cost of end-of-life vehicles based on design information from the development stage. The system was put into operation in 2003. Based on input data, including the materials of structural components and dismantling time, the OPERA system can calculate in the initial design stages the recycling rate and cost that will be incurred at the time of recycling. This enables us to design vehicles based on future recyclability.
