4.5.1 Renewable Materials
Reduce the use and depletion of finite raw materials and long-cycle renewable materials by replacing them with rapidly renewable materials. (Source: USGBC)
Rapidly renewable materials (e.g., bamboo, cork and linoleum flooring, wool carpeting, wheat board cabinetry, sunflower seed board panels, bio-based plastics from corn starch).
Use rapidly renewable building materials and products which are made from sources that are typically harvested within a maximum ten-year cycle.
An increase in demand is expected to make costs competitive with other materials.
Shorter growing cycles and higher density requires less land. More consistent harvesting cycles avoid the steady and eventual depletion of finite resources, or possible degradation of a productive ecosystem. Stabilizes trade and preserves forest land for future generations.
Rapidly renewable materials are considered to be agricultural products, both fiber and animal, that take 10 years or less to grow or raise and are harvested in an ongoing and sustainable fashion.
