RRS compiled a sampling of nationwide data from Governmental Advisory Associates and U.S. EPA sources to show current average materials recovery facility (MRF) efficiency rates and community recycling rates based on MRF construction year.
Efficiency rates show the percentage of materials, by weight, that enter the MRF and are not discarded as residue.
Newer MRFs open the door for single-stream programs in which people throw all recyclables in one bin – this improves participation and boosts tonnages but affects sorting efficiency, resulting in more residuals.
The tradeoff is positive overall as long as the increase in recycling outweighs the decrease in efficiency. Developments in MRF technology to reflect the mix of materials in the stream can help to capture more, and education is essential to minimize contamination.

Data Corner is compiled monthly by recycling consultancy RRS.

It can be difficult for a recycling program to implement major changes. Switching to single-stream, including more materials or removing others from the accepted list can all lead to more contamination in the stream.

In this section in July, we featured a MRF that hangs over the waters of New York Harbor: Sims Municipal Recycling’s Sunset Park facility in Brooklyn, N.Y.
