Toyota Motor Corporation (TMC) continues to work on reducing the impact of their vehicles on the environment as they are set to become the very first automaker to use biosynthetic rubber for engine and drive system hoses.

Starting next month, Toyota will begin using biohydrin rubber, which is a plant-derived bio-material, instead of petroleum-based hydrin rubber on vehicles manufactured in May before it fully rolls out the technology on all Toyota vehicle made in Japan by the end of 2016.

Being a biosynthetic rubber, biohydrin is estimated to reduce as much as 20-percent of material lifecycle CO2 emissions from hoses used in auto engines and drive systems.

In order to meet the resistance standards versus oil, heat, heat aging, ozone and gas permeability, biohydrin rubber employs a variety of compound technologies to bond plant-derived materials with petroleum-derived materials at the molecular level. This ensures that biohydrin rubber will deliver the resistance levels against heat and oil including the resistance and the durability required for vacuum-sensing hoses in engine and drive systems.

Toyota also ensured the viability of this innovation by making biohydrin rubber equal to hydrin rubber ‘in terms of quality and mass producibility, enabling large-scale use in commercial vehicles.’

Plans are already underway to use biohydrin to replace other high-performance hoses like brake and fuel line hoses.

This innovation is part of Toyota’s commitment to reach environmental goals set in October 2015, which is part and parcel of the Toyota Environmental Challenge 2050.
