Several of the toner cartridges that our buildings routinely buy claim to have recycled content, but their product documentation does not specify whether it is post-consumer or post-industrial material. Would it be acceptable to assume that this blended rate is all post-industrial and thus need to meet the higher threshold (20% rather than 10% for postconsumer) to comply? Example product documentation: http://www.biggestbook.com/details.jsp?R=9375445. See "Product Details" tab. Many HP toner products have the same problem.
