Overview

Recycled steel is melted, cast and rolled into long sections of train rail before being straightened and inspected. Seawater passes through filtration and high-pressure membrane systems to become drinking water; lightweight tubing is shaped around an athlete’s measurements to build a racing wheelchair; and precisely cut hardwood pieces are arranged into decorative parquet flooring.
