When you need air pollution control on the go, EnviroShield Systems has you covered. Founded in 2015 in Seattle, Washington, this young company has disrupted the industry with mobile air filtration units that can be deployed to temporary sites or used to supplement existing systems during peak production. Their “MobiScrub 500” is a trailer-mounted unit that can be towed to construction sites, disaster cleanup zones, or recycling pop-up events—perfect for the U.S. Army Corps of Engineers, which uses them for emergency e-waste disposal missions. But don’t let their mobility fool you—these units pack a punch. The MobiScrub 500 can filter 5,000 cubic feet of air per minute, removing 99.97% of particles as small as 0.3 microns. What clients love most is their “rapid response team”—EnviroShield guarantees delivery of a MobiScrub unit within 24 hours of an emergency request. As a Waste Management Inc. project manager noted: “When a hurricane hit our Florida recycling center in 2023, EnviroShield had a unit on-site the next day, keeping our workers safe while we cleaned up. You can’t put a price on that kind of reliability.”

Odor control might not sound glamorous, but in recycling facilities, it’s a make-or-break issue—especially for plants near residential areas. That’s where ClearSkies Industrial comes in. Founded in 2003 in Chicago, Illinois, this supplier has perfected the art of neutralizing unpleasant smells from mixed waste recycling, from rotting organic matter to chemical fumes. Their “ScentNeutral 700” uses a three-step process: first, capturing odors with a misting system, then breaking them down with bacteria-based enzymes, and finally masking any remaining traces with plant-derived fragrances (think “fresh pine” instead of “industrial chemical”). It’s a hit with facilities like Walmart distribution centers, which process tons of returned goods daily. What sets ClearSkies apart is their “odor mapping” service—they send a team to your facility to identify smell hotspots before designing a solution. A Whole Foods recycling manager in California shared: “Before ClearSkies, neighbors were complaining about our composting and recycling odors. Now, we get compliments on how fresh the air smells. It’s turned a liability into a community win.”
