RRS reviewed data from foam polystyrene plastic recycling programs in several communities that had received grants to target the material.
The numbers show a pattern of a sizable initial rise in foam collected per capita during the first year of the program, followed by more modest growth in subsequent years.
Programs built around multiple drop-off sites were able to collect more foam per capita than curbside programs or programs using a single drop-off site.
Data Corner is compiled monthly by recycling consultancy RRS.
