Teijin Limited has announced that its 'Eco Circle' plant-fibre based bio-polyester has been selected for use in the seats and interior trim surface of the new Nissan Leaf. 

The company says that it is the first time Eco Circle plant-fibre has been used for the interior of a mass-produced vehicle.

The seat and interior trim surface were co-developed by Teijin, automotive seat manufacturer Suminoe Teijin Techno Co., Ltd. and Nissan Motor Company Ltd. Specifically, Eco Circle plant-fibre is used for the seats, parts of the door trim, headrests and centre armrest.

More than 30% of Eco Circle plant-fibre’s composition is made with biofuels derived from sugarcane. 

Teijin has been expanding Eco Circle plant-fibre’s global market for applications ranging from apparel, car seats and interiors to personal hygiene products. The company aims to increase sales to over 50% of its total polyester fibre sales for automotive seats and interiors by 2015.
