What is a material recovery facility (MRF)?
A material recovery facility, or MRF, is a permitted site that receives mixed recyclable waste and separates it into material streams for onward sale to reprocessors.

</figure>Its economics run on contamination. Material that arrives mixed with the wrong things costs more to sort and is worth less when sorted, so the quality of what arrives determines whether the site makes money on a load or loses it.
Larger facilities are subject to sampling and reporting requirements covering input composition and output quality, which is what allows recycling figures to be substantiated rather than claimed.
For a collector, the MRF is where the round's segregation discipline is priced. Rejection or contamination charges are the feedback loop, and they arrive weeks after the behaviour that caused them unless someone connects the two.
What goes wrong in practice
- Contamination charges absorbed centrally and never traced back to the rounds or customers producing them.
- Segregation instructions given to customers once at sign-up and never reinforced.
- Output quality data held by the facility and never requested by the collector relying on its figures.
