1.1 This guide includes the handling, physical condition, and compositional considerations for selecting scrap gypsum panel products and the recycled gypsum derived from that scrap for recycling into new gypsum panel products. 1.2 This guide applies to scrap derived from gypsum panel products manufactured in accordance to Specifications C1177, C1178, C1278, C1396, and C1658. 1.3 This guide does not dictate the minimum amount of recycled gypsum a gypsum panel product manufacturer is required to use in producing new gypsum panel products. 1.4 This guide does not address recycling of gypsum panel products from demolition projects nor from any source other than scrap from newly installed gypsum panel products. NOTE 1--While these sources are outside the scope, they are not precluded from being recycled. This guide may be used as a basis for determination of basic criteria for any stream, as arranged between the contractor, recycler, and the gypsum panel product manufacturer. 1.5 This guide does not address the suitability of scrap gypsum panel products or the derived recycled gypsum for other uses such as use as an agricultural amendment, gypsum-based joint compounds, gypsum plaster, as an admixture, or other common uses of gypsum in products aside from gypsum panel products. 1.6 Units--The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
This practice will allow the industry to develop quality products that will meet their criteria while integrating recycled material, a demand of the marketplace.
