Top 10 Air Pollution Control System Suppliers for Lithium Battery Recycling Plants in the United States

1. EcoClean Systems (California)

When it comes to reliability, EcoClean Systems is the gold standard. Founded in 2005, this California-based company has spent nearly two decades refining its multi-stage filtration technology—specifically tailored for the unique challenges of lithium battery recycling.

Their flagship system, the EcoFilter Pro, combines a high-efficiency baghouse filter for dust (removing particles as small as 0.5 microns) with an activated carbon adsorption tower to trap VOCs like benzene and toluene. What really sets them apart? Their energy-efficient fans, which cut electricity use by up to 20% compared to competitors—no small feat for a system that runs 24/7.

EcoClean’s sweet spot is medium to large plants processing 500–2,500 kg of batteries per hour. Recent clients include a major recycling facility in Nevada that reduced emissions by 98% after installing their system. “We needed something that could handle the fine lithium dust and fumes from our shredding line,” said the plant manager. “EcoClean delivered—no complaints from the EPA, and our workers finally stopped coughing.”

2. AirPure Technologies (Texas)

AirPure Technologies might be newer (founded in 2010), but they’ve quickly made a name for themselves with smart, modular systems. Their claim to fame? The EcoGuard Li-Batt series, which uses catalytic oxidation to break down harmful gases at lower temperatures—saving energy while neutralizing pollutants.

What’s “smart” about it? Each system comes with IoT sensors that monitor temperature, pressure, and pollutant levels in real time, adjusting fan speeds and catalyst activity automatically. If a filter clogs or a gas spike occurs, the system alerts operators via a mobile app—minimizing downtime. For smaller plants (300–1,500 kg/hour), their compact, stackable design is a lifesaver, fitting into tight spaces without sacrificing performance.

One Texas-based recycler praised their flexibility: “We started small, processing 500 kg/hour, and as we scaled up, AirPure just added modules to our existing system. No need to tear everything out and start over. That saved us over $100k in upgrades.”

3. GreenGuard Solutions (Illinois)

Every recycling plant is different—and GreenGuard Solutions thrives on that. This Illinois firm specializes in custom-engineered systems, taking the time to map your plant’s layout, processes, and pain points before drawing up a single blueprint.

Whether you’re dealing with high levels of heavy metals (like cobalt or nickel dust) or need to target specific gases, their team of chemical engineers designs a solution that fits. For example, one client in Michigan needed a system to handle both dry dust from shredding and acid mists from leaching. GreenGuard’s hybrid design paired a wet scrubber for mists with a dry baghouse for dust—all in a footprint that worked with the plant’s existing conveyor belts.

They also excel at rapid installation, with most systems up and running in under 6 weeks. “We were worried about downtime during setup,” said a plant operator in Ohio. “GreenGuard installed their system over a long weekend—we barely missed a beat.”

4. CleanAir Innovations (Pennsylvania)

High-temperature processes (like pyrolysis or melting) release some of the trickiest pollutants—and CleanAir Innovations specializes in taming them. Founded in 2008, this Pennsylvania company’s systems are built to withstand extreme heat, with heat-resistant ceramic filters that stay effective even at 600°C.

Their ThermaShield system includes a pre-cooling chamber to lower gas temperatures before filtration, followed by an acid gas neutralization tower (using sodium bicarbonate) to tackle hydrogen fluoride and sulfur dioxide—common byproducts of lithium battery recycling. It’s a heavy-duty setup, ideal for large plants processing 1,500–5,000 kg/hour.

A Pennsylvania recycler running a high-temperature pyrolysis line put it this way: “We tried cheaper systems, but the filters melted within months. CleanAir’s ThermaShield has been going strong for 3 years—no replacements needed. Worth every penny.”

5. BlueSky Environmental (Florida)

Not every recycler has the space or budget for a massive, fixed-in-place system. Enter BlueSky Environmental, the go-to for compact, mobile air pollution control. Founded in 2015, this Florida startup has reimagined what a control system can be—small, portable, and ready to plug in.

Their MiniGuard system is mounted on a skid, so you can wheel it right next to your shredder or sorting line. It uses a HEPA filter and activated carbon canister to handle dust and VOCs, with battery-powered controls for areas without easy access to electricity. For small plants (100–500 kg/hour) or temporary operations, it’s a game-changer.

“We run a mobile recycling unit that travels to battery collection points,” said a client in Florida. “BlueSky’s MiniGuard fits in the back of our truck. Now we can recycle on-site without worrying about local air quality rules.”

6. UltraFilter Systems (New York)

Precision is the name of the game for UltraFilter Systems. Since 2003, this New York company has focused on medical-grade filtration—tech that’s now saving the day in lithium battery recycling. Their UltraHEPA filters capture 99.97% of particles as small as 0.3 microns, including lithium metal dust and cobalt oxide particles that other systems might miss.

Paired with their dual-stage carbon adsorption (first a pre-filter to catch large molecules, then a fine filter for smaller ones), their systems are a favorite for plants in strict regulatory areas like California or New York. They’re also surprisingly quiet, operating at just 65 decibels—no more shouting over the hum of machinery.

“We had an EPA inspection last year,” said a New York plant manager. “UltraFilter’s system kept our emissions so low, the inspector thought our monitors were broken. They weren’t—just UltraFilter doing its job.”

7. EcoFlow Tech (Oregon)

Sustainability isn’t just about clean air—it’s about clean energy, too. EcoFlow Tech, founded in 2018, has pioneered air pollution control systems that generate as much energy as they use. Their EcoCycle system captures waste heat from the filtration process and uses it to power fans and sensors, cutting grid electricity use by up to 40%.

For plants with solar panels, their systems can even feed excess energy back into the grid. And with a carbon footprint 30% lower than traditional systems, they’re a hit with eco-conscious recyclers. “We’re not just recycling batteries—we’re trying to be a zero-waste facility,” said an Oregon client. “EcoFlow’s system helped us get there.”

8. AirShield Industries (Georgia)

Regulatory compliance can feel like a full-time job—but AirShield Industries takes the stress out of it. Founded in 2001, this Georgia company builds systems with compliance baked in, from auto-generated EPA emissions reports to real-time monitoring dashboards that flag issues before they become violations.

Their CompliancePro software syncs with the system’s sensors, tracking pollutants like lead, mercury, and VOCs, and sends alerts if levels creep near legal limits. For plants in states with strict air quality boards (looking at you, California and New Jersey), this peace of mind is priceless.

“We used to spend 10 hours a week compiling emissions data,” said a Georgia plant manager. “Now AirShield’s system does it automatically. I can focus on running the plant, not filling out forms.”

9. PureCycle Solutions (North Carolina)

Why choose between dry or wet scrubbing when you can have both? PureCycle Solutions, founded in 2014, has perfected the hybrid approach, combining the best of dry filtration (for dust) and wet scrubbing (for gases) in one system. Their FlexiScrub design lets you switch modes based on the pollutants you’re dealing with that day—no need for separate setups.

Even better, their water-saving tech recycles 90% of the water used in wet scrubbing, making it ideal for drought-prone areas. And with low chemical use (they use biodegradable neutralizers), they’re kinder to the planet, too. “We process different battery types daily—some release more dust, others more gas,” said a North Carolina recycler. “PureCycle’s system adapts on the fly. It’s like having a Swiss Army knife for air pollution control.”

10. GreenAir Engineering (Ohio)

Not every plant has a huge budget—and GreenAir Engineering proves you don’t need one to get clean air. Founded in 2007, this Ohio company specializes in low-cost, high-efficiency systems that prioritize affordability without cutting corners on performance.

Their DIY installation kits come with step-by-step videos and pre-assembled parts, slashing labor costs by up to 50%. And their replaceable filter cartridges are priced 30% lower than competitors, making ongoing maintenance a breeze. For small to medium plants (300–1,200 kg/hour) just starting out, they’re the perfect entry point.

“We were a startup with limited funds,” said an Ohio plant owner. “GreenAir’s system cost half what the other quotes were, and it still passed our state’s emissions tests. They proved you don’t have to spend a fortune to do the right thing.”
