Full title and description

ASTM C1881-24 — Standard Guide for Closed-Loop Recycling of Scrap Gypsum Panel Products. This guide provides recommended practices for evaluating, handling, and selecting scrap gypsum panel products and the recycled gypsum produced from them for reintroduction into the gypsum panel manufacturing closed-loop supply chain.

Abstract

ASTM C1881-24 offers guidance to manufacturers, recyclers, contractors, and waste-management teams on the physical, compositional, and handling criteria used to determine the acceptability of gypsum panel scrap for closed‑loop recycling into new gypsum panel products. It clarifies what is in scope and what is excluded, and explains that the guide is advisory (not a mandatory specification of minimum recycled content).

Scope

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. It applies to material derived from gypsum panel products manufactured in accordance with Specifications C1177/C1177M, C1178/C1178M, C1278/C1278M, C1396/C1396M, and C1658/C1658M. The guide does not mandate a minimum recycled‑gypsum content, nor does it address recycling of gypsum panels from demolition/renovation projects or uses of recycled gypsum outside of gypsum panel products.

Key topics and requirements

• Definitions and intent: guidance document (guide) rather than a prescriptive specification.
• Acceptance criteria for scrap gypsum panel products — physical condition, contamination limits, and compositional considerations.
• Guidance on segregation, collection, and handling practices for construction and manufacturing scrap destined for closed‑loop recycling.
• Applicability limited to gypsum panel products made to referenced ASTM specifications (C1177/C1177M, C1178/C1178M, C1278/C1278M, C1396/C1396M, C1658/C1658M).
• Clarification of exclusions: demolition/renovation waste streams and non‑panel end uses (e.g., agricultural amendment, joint compounds) are outside the guide’s scope.
• Emphasis on industry agreement — determinations may be made jointly by contractor, recycler, and manufacturer.

Typical use and users

Used by gypsum panel manufacturers, recyclers and processors, construction waste‑management teams, sustainability managers, environmental and regulatory specialists, procurement/specification authors, and contractors involved in panel installation and off‑cut handling. The guide supports closed‑loop recycling program design, acceptance testing, and contract/specification language development.
