Such blocks are used to minimize damage to beaches and beachfront properties, but are usually made from concrete and cement—materials that have a poor carbon-emissions footprint and are unsuitable for marine life.
In addition to using natural materials, the Ecotrapod design includes bio-porous spiral surfaces that maximize structural strength, allow algae to attach, and provide a habitat for certain species of fish and shellfish.
Chiang and Lin, who collaborated with C-Cube, Lotos, and Everplast, have received several awards for the design.
