By collecting defective bumpers, crushing them and removing surface paint, Mazda Motor Corporation performs bumper to bumper recycling. Satake's optical sorter technology is used to remove pellets from which paint has not been completely removed by the paint removal process. This technology has improved paint removal efficiency from 98.5% to 99.9%.

Since March, 2005, Mazda has used Satake technology to recycle old bumpers into new bumpers.
