If we make a desk, of multiple materials, ie plywood; particle board; plastic laminate & veneer. If 3 of the 4 materials have FSC mixed claim, & 1 is FSC 100% would we calculate it as 100% for all inputs? If 3 of the 4 inputs have recycled content, would any of the FSC material count towards the MRc7, or would that apply only to new wood?
