Gypsum Recycling Committee Updates

The gypsum recycling committee meeting began with new member introductions. The committee provided updates on their ongoing Life Cycle Assessment (LCA) project comparing gypsum drywall recycling with landfilling, which is currently undergoing third-party review. The committee outlined future work plans including addressing asbestos risk in post-consumer drywall, developing a resource library, and creating standard operating procedures for gypsum drywall recycling. The conversation ended with Amanda introducing two guest speakers, Paul Henderson from Metro Vancouver and Michael Elliott from Massachusetts DEP, who were set to present on state and regional policy frameworks influencing drywall diversion and recycling markets.

C&D Waste Management Policies

Michael presented on Massachusetts’ solid waste management policies, focusing on construction and demolition (C&D) waste reduction efforts. He outlined the state’s C&D waste reduction goal of 260,000 tons by 2030 and discussed the implementation of waste disposal bans, including gypsum wallboard since 2011. Michael noted that despite these efforts, only 9-12% of potentially available gypsum wallboard is being recycled, leading to proposed solutions including increased compliance inspections and promoting job site source separation. Paul then began his presentation, sharing similarities between Massachusetts and Metro Vancouver’s solid waste management approaches, though his full presentation was not captured in the transcript.

Gypsum Waste Management Discussion

Paul presented Metro Vancouver’s waste management system, highlighting their 65% diversion rate and successful disposal ban program that includes gypsum. Michael and Terry discussed Massachusetts’ challenges with enforcing gypsum bans, noting they have fewer inspectors and rely on hauler compliance rather than facility-based inspection like Metro Vancouver’s system. The discussion revealed that while USA Gypsum successfully processes Massachusetts’ gypsum, having a local processor would be beneficial but requires sufficient volume to justify the overhead. Key challenges identified included the need for end markets before processing can begin and the importance of contractor licensing to prevent illegal dumping.
