Specifications include, but are not limited to: conduct material characterization research at material recovery facilities (MRFs) in California to gather data on whether a product or packaging is collected and processed for recycling. Senate Bill (SB) 343 (Allen) directs CalRecycle to publish a material characterization study. This study is only focused on the processing of traditional recyclables (glass, plastic, paper, and metal), items that may have a chasing arrow symbol, and items with labeling that otherwise directs a consumer to recycle that material. This study will focus on selected Large Volume Transfer or Processing Facilities in California. This study specifically excludes organics (i.e., compostable material) and CDI (Construction, Demolition, and Inert) processing lines.
