culletin

Culletin is a term used in the waste management and glass recycling sectors to describe a newsletter or bulletin focused on cullet, the recycled glass fragments used as feedstock in glass manufacturing. The word blends cullet with bulletin, and while not standardized, it appears in industry discussions and internal communications as a label for information about cullet markets, technologies, and policy developments.

Etymology and usage vary, but culletin is commonly understood to denote periodic communications that summarize news, research, and practical guidance related to cullet handling and recycling. It may be issued by trade associations, recycling facilities, research groups, or municipal programs. The publication may be produced on a monthly, quarterly, or weekly cadence, depending on the issuing organization.

Contents typically found in a culletin include market updates on cullet supply and demand, processing technology advancements (such as sorting, washing, and contamination control), regulatory or policy developments, standards and quality considerations, case studies, and notices of conferences or training opportunities. Some culletins also feature technical notes, best practices, and data dashboards related to recycling performance.

Formats and access vary. Culletins may be distributed as email newsletters, PDF digests, or online articles, and access may be restricted to members of an organization or available to the public. They serve as a communication tool to align stakeholders, share innovations, and promote efficiency in cullet processing and glass production.
