Mazda has officially become the world's first automaker to successfully recycle scrapped bumpers from end-of-life vehicles into raw materials for new bumpers. The Japanese automaker began this eco-friendly technology on August 21st and says it will initially be put to use for rear bumpers on its Biante minivan, which is sold in Japan. The Biante minivan currently offers two available engines, which are the MZR 2.0-liter DISI (direct-injection spark ignition) and the MZR 2.3-liter unit.
