Expanded Kenaf Base Material

Contributing to carbon neutrality through the development of products using kenaf

Toyota Boshoku has been developing and producing internal components using kenaf—an annual grass—for many years.
Replacing conventional resin materials with foaming agents from kenaf boards has allowed reduction of mass, as well as reductions in CO2 emissions, which help us contribute to carbon neutrality.

Toyota Boshoku’s Strengths

Since first using kenaf fibers in the base material for interior door trims in the year 2000, we have been building expertise and know-how regarding products that use kenaf raw materials.
Putting this know-how into practical use, we have developed expanded kenaf base material, and thanks to increased efficiency in production processes as a result of our Simultaneous Back-Injection Molding Technology, our efforts in bringing Competitive Kenaf products onto the market have been successful. We are now continuing to expand the range of car models that make use of kenaf products.

Helping Change the World

Acting as an industry pioneer, Toyota Boshoku is promoting introduction and development of renewable raw materials to help curb the depletion of resources, such as through our continued use of CO2-absorbing plant-derived materials like kenaf in our products.
Additionally, we are working together as a group to curtail waste produced and water used throughout our production stages, and are proactively continuing with initiatives aimed at helping build a recycling-oriented society.
