Toyota Rolls Out Plant-Based Rubber Parts

Posted Sunday, May 08, 2016 by nhtwpprod

Toyota Motor Corporation, along with Sumitomo Riko Co, Ltd. and Zeon Corporation, have developed a plant-based, rubber-like material, which has been named biohydrin. Biohydrin is a unique synthetic compound which allows plant-based materials to bond with petroleum-based materials. The biohydrin rubber is durable and provides similar resistance to oil and heat—typical conditions common under the hoods of most vehicles.

Toyota, along with its partners, started working on the development of biohydrin last October (2015) when Toyota announced its new “Toyota Environmental Challenge 2050.”

This new project program is an effort on the car manufacturer’s part to reduce its carbon emissions and waste globally by developing its own green and environmentally-friendly initiatives through new innovations, as well as to encourage other manufacturing firms to do the same.

Ideally, Toyota would like to reduce its carbon emissions of all of its vehicles to zero.

Synthetic biohydrin rubber is the first innovation created to further this cause. It is estimated, by Toyota, the use of this new rubber for hoses in its vehicle lines will help reduce its carbon footprint by about 20%, compared to traditional all-petroleum-based rubber hoses. The new hoses will start to be placed into production in Toyota’s Japanese manufacturing plants in May.

Toyota plans on using biohydrin rubber to make the vacuum hoses used on its vehicles. Toyota has not announced what vehicle models would be the first to have the new eco-friendly vacuum hoses. However, Toyota does manufacturer Lexus vehicles and the Toyota Prius in its Japanese plants, so it would be easy to speculate these brands would be the first vehicle models produced which will eventually make their way to Toyota dealerships around the world later this summer or in early fall.

Toyota does plan to implement the new biohydrin rubber vacuum hoses at all of its global manufacturing facilities by the end of the year. As such, by 2017 all vehicles manufactured by Toyota will feature the eco-friendly hoses. Vacuum hoses are not the only rubber hoses on its vehicles that Toyota is exploring replacing with biohydrin.

Currently, Toyota is using epichlorohydrin (petroleum-based) rubber hoses for braking and fuel systems. This particular rubber is used because the hoses used with these systems must have a high tolerance to heat, corrosion, and normal wear and tear. However, Toyota is experimenting with biohydrin brake line hoses and biohydrin fuel line hoses.

Toyota wants to ensure that the use with brake fluid and gasoline will not pose any problems for the plant-based materials used in the hoses. If all goes well, and the hoses perform well, Toyota plans on implementing them in the near future and eventually to all of their manufacturing facilities worldwide.

It will be interesting to see what other future innovations Toyota Motor Corporation is going to development in its effort to reduce its vehicle lines to zero carbon emissions.
