Building a Recycling Society: Development and Design initiatives

Basic Approach

The production of automobiles entails the use of a variety of different resources, including metals such as iron and aluminum, and resin, glass, and rubber.
By taking care over every 1mm and every 1g, Daihatsu seeks to create small-size cars that use minimal resources.
Based on various automotive recycling laws in Japan and overseas, we aim from the design and development stages to develop cars that are easy to use for the 3Rs of Reduce, Reuse, and Recycle.
We not only create cars that use minimal resources, but also promote the expansion of Car to Car recycling, in which resources recovered from end-of-life vehicles are reused in the production of new vehicles.

Existing Initiatives

The current Sixth Daihatsu Environmental Action Plan sets out the following aims for Building a Recycling Society

Reducing CO2 emissions
・Developing technologies aimed at the use of recycled Automobile Shredder Residue (ASR) materials, and the use of 100% bio-resins

Eco-Design Cars: designs for easy resource recovery and easy dismantling
・Formulating recycling design guidelines, based on the recycling design guidelines set out by the Japanese Automobile Manufacturers Association, of which Daihatsu is a member
・Reducing attachment points
・Improving drainage of fuel and liquids
・Using material indicators
・Publishing disassembly manuals

Engaging in ongoing and new activities aimed at resource recovery

Goals for 2025

In the Seventh Daihatsu Environmental Action Plan, Daihatsu outlined its goals for 2025.
These goals include refining its existing initiatives of creating cars that use minimal resources, and of reusing and rebuilding. We are also accelerating activities aimed at expanding Car to Car recycling, in which resources recovered from vehicles that reach the end of their lives around 2050 will be reused in the production of new vehicles.
To this end, in the design and development stages of cars that will be launched between 2030 and 2035, we intend to develop and incorporate items with high recyclability so that they can be disposed of more easily.

Examples of Concrete Initiatives

Developing Materials Suited to Recycling

Daihatsu is working to reduce the number of different materials it uses, both by promoting the development of thermoplastic resins, which are well suited to recycling, and by aiming to unify the materials necessary for automobile production.

Establishing technologies for using biodegradable plastics

Biodegradable plastics can be completely decomposed through the actions of microbes.
In addition, by using plant-based resources instead of fossil fuels, which may face resource constraints in the future, biodegradable plastics have the potential to be CO2 emissions-free materials.
Daihatsu is established a technology to introduce biodegradable plastics into the resin parts materials.
