The "Sustainable Materials Eco - Trait" applies to products that are made from low-impact sustainable raw materials, such as bamboo, hemp and wood harvested from managed forests among other materials. For the most part, sustainability refers to the process of attaining raw materials in a production or agricultural capacity. The term is often used synonymously with “renewable resources”. "Sustainable” may also refer to different harvesting methodologies used to procure certain materials or energy such as lumber, rubber or electricity. For example, products pertaining to solar power on GreenCupboards.com fall under the Sustainable Materials Eco-Trait since the sun’s energy is considered “renewable”. Similarly, products made with actual renewable, sustainably procured resources such as bamboo also fall under the Sustainable Materials Eco-Trait. http://www.greencupboards.com/sustainable-materials-top-5/
