How will the USGBC define the term "closed-loop recycling"? Businessdictionary.com defines closed-loop recycling as a "Production system in which the waste or byproduct of one process or product is used in making another product." The example provided is recycling waste newspaper to make paper-board or other types of paper. Would this be considered accurate? If so, does this include a product that is considered to be at the end of it's useful life (as mentioned in question 4 above)? And to what extent? In other words, will there be a minimum amount of recycled content derived from the closed-loop process? Also, because my company produces a panel product that cannot be recycled, could a take-back program be a scenario where "drop" material (or material leftover after sheets are fabricated into panels) is reclaimed and cut into small samples qualify? The same question can be posed to end-of-life material (or material pulled from an existing building).
