Thorough Measures for Waste Materials
Nissan actively promotes measures based on the three Rs-reduce, reuse and recycle-in its production processes whenever possible, striving to minimize the waste generated and maximize recycling efficiency by means of thorough sorting of waste. Our efforts have paid off. As of the end of fiscal 2010, we have achieved a 100% recovery rate at all of our production sites in Japan: five manufacturing plants, two operations centers and five affiliates. In Mexico, the Aguascalientes plant achieved this in 2011. We are also working to bring this rate to an automotive-industry-leading level in each region of the globe, and plan to reduce the amount of waste from our production factories by 2% annually in Japan and by 1% annually worldwide compared to waste levels expected if no special steps had been taken from fiscal 2011 onward.
Reduce - Curbing the Generation of Waste
A panel of experts was formed in fiscal year 2002 to study technical measures for controlling waste at the source of generation. Nissan is involved in a number of activities including using returnable palettes, recycling cutting oil, investigating ways to bring our use of cutting oil to zero, and investing in equipment to drastically reduce the amount of waste we produce.
Reduction of packing and packaging materials
Nissan has been making great efforts to reduce the number of wooden pallets and cardboard boxes used in import and export parts shipping, replacing them with units made from steel for more than 30 years, and plastic for more than 20 years, which can be returned and foldable for reuse. Since fiscal 2011, the adoption rate for these containers has exceeded 98%. We have also been working with our Alliance partner Renault to expand the use of our globally standardized, returnable containers. Through design activities carried out concurrently with logistics operations, we have recently been considering ways to optimize the shape of parts from the development stage, thus contributing to a reduction in the packaging materials we use.
Reuse - Reusing Waste
Efforts at reusing include the collection and repeated use of protective coverings for parts, which in the past were disposed of after use. The goal is to steadily expand the range of parts and materials being reused at plants throughout Japan and at overseas facilities.
Caps attached to protect parts during delivery to Nissan from suppliers are reused as dustproof caps in the transport of completed engines from engine plants to assembly plants.
Recycle - Recycling Waste
Recycling based on thorough sorting of waste materials and control of waste generation at the source is essential to encourage waste reduction. Nissan aims for zero emissions in Japan to eliminate as much as possible of the waste generated during manufacturing activities.
Recycling Metal Remnants
Remnants of panels cut at press plants recycled as raw material metal.
Aiming acceleration of material scrap recycling
In order to improve the quality of material scrap and accelerate of resource recycling, the materials scrap that is produced in the process of manufacturing in Nissan and our supply chain is consolidated in our control scheme.
Details are as follows
- Company scope; Nissan, its affiliates, and parts suppliers that use materials under centralized procurement are prioritized.
- Target; Materials scrap (mainly steel scrap, as the first step), produced in the process of manufacturing as well as those in disposal of jigs/tools, equipment, buildings, etc.
- Nissan or its subcontractor will decide the purpose and buyer of scrap with the cooperation of recycling entities.
