(Guide)Standard Guide for Closed-Loop Recycling of Scrap Gypsum Panel Products
Standard Guide for Closed-Loop Recycling of Scrap Gypsum Panel Products
SIGNIFICANCE AND USE
4.1 This guide is intended to provide guidance in determining the acceptability of scrap gypsum panel products and the resultant recycled gypsum.
4.2 This guide is also intended for use by construction waste management teams in establishing the methods for segregating and collecting scrap.
4.3 This guide does not dictate that any manufacturer must accept or use recycled gypsum in manufacturing gypsum panel products, nor does it mandate that scrap must be recycled by way of a closed-loop system.
Note 2: Closed-loop recycling is just one means to consider, as there are many pathways for landfill diversion.
SCOPE
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.
