renewable: a material that is replenishable and replenished on some reasonable time scale, including but not limited to wood, fibers, plant-based plastics, and biobased fuels. Source: paraphrased from BIFMA e3-2008 Furniture Sustainability Standard § 3.39. FTC states that renewable material should be quantified (what it is, how it is sourced, why it is renewable). For product that contains less than 100% renewable materials (excluding minor, incidental components), quantify the percent renewable. Source: 16 C.F.R. § 260.15, FTC’s Green Guides.
