In a world grappling with growing mountains of waste, Materials Recovery Facilities (MRFs) play a vital role in the fight for environmental sustainability. These centralized processing centers are the unsung heroes of recycling, transforming discarded materials into valuable resources.
What Happens at an MRF?
Think of an MRF as a giant sorting machine, meticulously separating different types of recyclables from the waste stream. The journey begins when mixed recyclables arrive, typically collected from residential and commercial sources. Here's a simplified breakdown of the process:
Why are MRFs Important?
The impact of MRFs extends far beyond simply sorting trash:
