Description of ASTM-C1881 2020ASTM C1881-20Historical Standard: Standard Guide for Closed-Loop Recycling of Scrap Gypsum Panel ProductsASTM C1881Scope 1.1 This guide provides guidance for 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 material derived from gypsum panel products manufactured in accordance with Specifications C1177/C1177M, C1178/C1178M, C1278/C1278M, C1396/C1396M, and C1658/C1658M. 1.3 This guide does not dictate the minimum amount of recycled gypsum a gypsum panel product manufacturer is required for use in producing new gypsum panel products. 1.4 This guide does not address recycling of gypsum panel products from demolition or renovation projects. 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 agreed upon between the contractor, recycler, and the gypsum panel product manufacturer. 1.5 This guide does not address the suitability of recycled gypsum for other uses such as an agricultural amendment, for use in gypsum-based joint compounds or gypsum plaster, as an admixture or other uses of gypsum aside from gypsum panel products. 1.6 The values stated in inch-pound units are to be regarded as 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
