Purification technologies capable of removing contaminants from plastic waste are key to increasing plastic recyclability. Here, the authors report a membrane-based size-exclusion process and show that ceramic tubular ultrafiltration membranes can remove over 90% of hexabromocyclododecane from virgin and post-consumer polystyrene, while also eliminating polymer tailings from degraded polymer chains.
