Material Recovery Facilities (MRFs) and Processing Facilities are an important component of the increase in recycling in St. Louis. These facilities process Single-Stream, which is generally received from residential and commercial customers, as well as from private and municipal haulers. Single-Stream is the collection of a wide variety of recyclables (paper, plastic, aluminum, etc.) which are all collected together - eliminating the need for sorting.
At a Materials Recovery Facility (MRF), mixed recyclables are sorted, crushed, shredded and/or baled mechanically or manually. This is an intermediate processing step between local curbside and drop-off collections, and the end users who recycle these materials into new products.
There are five MRFs/Processing Facilities currently processing recyclables collected throughout the District. One of the facilities - Recycle City - is owned and operated by the City of St. Peters, a municipality in St. Charles County. In addition to processing recyclables, the St. Peters facility also provides composting for yard waste and serves as a Transfer Station.
