Scrap yards keep our world moving, but too often, they’ve been forced to run on pen, paper, or clunky outdated software. We’ve seen firsthand how that slows down buying, selling, dispatch, and reporting - and costs recyclers real money. That’s why we built ReMatter: the modern operating system for scrap recyclers. Our cloud-based platform makes it simple for yards of any size to handle scale purchasing, inventory management, bin tracking, dispatching, and sales documents - all in one place. With our iPhone/Android mobile app, drivers and operators stay connected on the go. The industry has noticed and we’re proud to be the Recycled Materials Association’s Innovation Partner of the Year (2025). Our mission is simple: give recyclers the tools to run faster, smarter, and more profitably. ? Want to see how the #1 scrap software can work for your yard?
