Design for Recycling (Based on Eco-VAS)

Use of Renewable Resources

Eco plastics

Adopting and expanding use of plastics derived from plants

Because eco plastics are derived from plants, they not only help conserve the petroleum resources from which conventional plastics are derived, but are also a carbon neutral* product that offsets any CO2 emitted during its life cycle from production to post-use disposal. These materials will help reduce our use of limited petroleum resources.

In May 2003, Toyota used eco plastics for the first time in the Raum (launched in May 2003) and developed new plastic materials for interior parts, such as scuff plates, roof headliners and seat cushions in 2008.

Toyota has expanded use of eco plastics to 60% of the total area in interior parts for the SAI launched in October 2009.

Furthermore, in extension of the technology developed in recycling bumpers for repair services, a new recycled material based on end-of-life vehicle was created. Toyota applied it first to deflectors and so on after developing a process to assure the quality by eliminating foreign particles, such as dirt adhering to bumpers, and fine-tuning the compound.

Concept of carbon-neutral eco plastic

Concept of carbon-neutral eco plastic

* Zero CO2 increase over lifecycle.
The concept is that the plant absorbs CO2 from the air by photonic synthesis and grows, so CO2 in the air will not increase even when the plant is burned in the lifecycle.
