The basic material is a polyester fibre called PPT (polypropylene terephthalate) which is produced by combining 1-3PDO (propanediol) from maize with terephthalic acid, a petroleum-based component.
Honda improved the stability of the material by producing very fine fibres and spinning them into a multi-strand yarn. The flexibility of this yarn enabled it to weave a soft, pleasant-feeling yet durable upholstery material suitable for mass production using existing weaving processes.
Honda has been using the concept of LCA (life cycle assessment) to reduce carbon dioxide emissions throughout the entire life cycle of a vehicle — from production and usage to disposal.
Bio-fabric will enable the company to reduce the energy used during the production process by 10-15 percent compared to the production of petroleum-based polyester material, due to the use of plant-based ingredients in the raw material.
This can reduce the carbon dioxide produced in building a car by 5kg.
