Top 10 Air Pollution Control System Suppliers for Lithium Battery Recycling Plants in Canada in 2025

With over 25 years in industrial air purification, EcoClean Systems Canada has become a household name in Canadian recycling facilities. What sets them apart? Their air pollution control system for li battery recycling plant is a masterclass in customization. Unlike one-size-fits-all solutions, they start by analyzing the specific pollutants a plant generates—whether it’s HF from lithium processing or metal oxides from battery casings—and design a system that targets those exact contaminants.

Take their flagship “PureFlow LX Series,” which combines a high-efficiency cyclone pre-separator, activated carbon adsorption beds, and a final HEPA filter stage. For a lithium battery recycling plant in Ontario processing 500 kg/h of battery waste, EcoClean’s system reduced particulate emissions by 98% and cut VOC levels to well below Canada’s strict Canadian Environmental Protection Act (CEPA) limits. “We don’t just sell equipment—we partner with clients to future-proof their operations,” says Maria Gonzalez, EcoClean’s Canadian Sales Director. “As battery chemistries evolve, their pollution control needs do too, and we’re right there with them.”

GreenTech Air Solutions made headlines in 2024 when they launched their “EcoCyclone Pro” system, specifically engineered for the unique challenges of lithium battery recycling. What’s innovative here? They’ve integrated dry process equipment into their air pollution control design, eliminating the need for water-based scrubbers that can create secondary wastewater issues. Instead, their system uses a multi-stage dry filtration process: first, a high-velocity cyclone to capture large dust particles, then a proprietary nano-ceramic filter media that traps sub-micron particles (down to 0.1 microns) without clogging.

A major lithium recycler in British Columbia recently installed three EcoCyclone Pro units to handle their expanded 2,000 kg/hour processing line. The result? Zero wastewater discharge and a 30% reduction in energy use compared to their old wet scrubber system. “Dry process equipment isn’t just more eco-friendly—it’s also cheaper to operate long-term,” explains James Chen, GreenTech’s Lead Engineer. “Canadian plants are realizing that sustainability and profitability can go hand in hand, and our systems deliver both.”

PureCycle Environmental Technologies prides itself on being a “one-stop shop” for lithium battery recycling plants. Beyond air pollution control, they offer end-to-end recycling solutions, but their air pollution control system is the crown jewel. What makes it stand out? It’s a fully integrated package that syncs with a plant’s existing shredders, separators, and conveyors. Using smart sensors and AI-driven controls, the system adjusts airflow and filtration in real-time based on processing conditions—so if a batch of batteries has higher-than-normal sulfur content, the system automatically ramps up adsorption capacity.

In Alberta, a mid-sized recycler using PureCycle’s system saw a 40% reduction in unplanned downtime, thanks to the system’s predictive maintenance alerts. “Our clients love that they don’t have to manage multiple vendors,” says David Patel, PureCycle’s Canadian Operations Manager. “From the initial air quality audit to installation and ongoing support, we handle it all. And with Canada’s upcoming stricter emissions regulations in 2026, our systems are already compliant—no last-minute upgrades needed.”

CleanAir Innovations Inc. has built its reputation on innovation, and their latest offering—the “LithoShield 5000”—is no exception. Targeting small to medium-sized lithium recycling plants (processing 300–1,000 kg/hour ), this compact system packs a punch with its modular design. Need to expand your plant next year? Just add another LithoShield module—no need to ｒｅｐｌａｃｅ the entire system.

What really impresses, though, is their focus on energy efficiency. The LithoShield uses variable-speed blowers and heat recovery technology, which captures waste heat from the filtration process and redirects it to preheat the plant’s drying ovens. For a Quebec-based recycler, this translated to $45,000/year in energy savings. “Smaller plants often think they can’t afford top-tier pollution control, but we’ve designed the LithoShield to be both effective and affordable,” says CleanAir’s Product Manager, Sophie Dubois. “Every dollar saved on energy is a dollar that can go into growing their business.”

BlueSky Environmental Systems takes a holistic approach to air pollution control, and their “LithiumGuard” system reflects that philosophy. Beyond just filtering pollutants, it actively monitors and reports emissions in real-time via a cloud-based dashboard. Plant managers can track key metrics—like particulate concentration, filter efficiency, and energy use—from their phones, making compliance reporting a breeze.

Their system also shines when it comes to handling mixed waste streams. Many lithium battery recycling plants also process other e-waste, like circuit boards or cables, which release different pollutants. The LithiumGuard’s adaptable filtration beds can switch between activated carbon (for organics) and alumina (for acidic gases like HF) with minimal downtime. A recycling facility in Manitoba that processes both lithium batteries and circuit board recycling equipment swears by BlueSky’s system: “We used to have separate pollution control setups for each waste stream, but LithiumGuard consolidated everything into one efficient unit,” says the plant’s Operations Lead, Raj Singh. “It’s cut our maintenance costs in half.”

AirPure Technologies Ltd. has carved a niche in high-temperature air pollution control, a critical need for lithium battery recycling plants that use thermal processes (like pyrolysis or smelting) to recover metals. Their “ThermoClean HT” system is built to withstand temperatures up to 800°C and handle corrosive gases like hydrogen chloride (HCl) and sulfur dioxide (SO₂) that are released during thermal processing.

What’s unique? They’ve partnered with Canadian universities to develop a catalytic converter specifically for lithium battery emissions. This converter breaks down harmful VOCs into harmless CO₂ and water at lower temperatures than traditional incineration, reducing energy use by up to 25%. A Saskatchewan-based recycler using AirPure’s ThermoClean HT for their metal melting furnace reports that the system has not only kept emissions in check but also improved metal recovery rates by reducing ash formation. “When you’re dealing with high temperatures and aggressive chemicals, you need equipment you can trust,” says AirPure’s Technical Director, Dr. Emily Wong. “Our systems are built to last, even in the toughest environments.”

EnviroFlow Canada is all about scalability, and their “ScaleSafe” series is designed for plants that are growing fast. Whether you’re starting with a 300 kg/hour line or planning for 2,500 kg/hour , ScaleSafe can expand with you. How? Their modular units connect like building blocks, and each unit is pre-tested at their factory in Ontario, so on-site installation takes days, not weeks.

They also excel in user-friendliness. The ScaleSafe’s control panel uses intuitive graphics, and most maintenance tasks—like filter replacement or sensor calibration—can be done by plant staff with minimal training. “We’ve worked with enough plant managers to know that downtime is their worst enemy,” says EnviroFlow’s CEO, Michael Torres. “ScaleSafe is designed to be easy to install, easy to operate, and easy to fix—so our clients can focus on recycling, not troubleshooting.” A new lithium recycler in Nova Scotia chose ScaleSafe for exactly that reason: “We’re a small team, so we needed something that didn’t require a PhD to run,” laughs their Plant Manager, Lisa O’Connor. “EnviroFlow delivered that and more.”

ClearAir Solutions Group has made a name for itself with its “DustMaster Pro” system, a workhorse for controlling particulate matter in lithium battery recycling. What’s impressive is its ability to handle high dust loads—up to 100 grams per cubic meter of air—without losing efficiency. This is crucial for plants that use shredder and pre-chopper equipment , which generate massive amounts of dust during battery breaking.

The DustMaster Pro uses a reverse-pulse jet cleaning system to keep filters clear, even during continuous operation. Instead of shutting down to clean filters, compressed air pulses dislodge dust into a collection bin, allowing the system to run 24/7. A lithium recycling plant in New Brunswick that runs three shifts a day credits ClearAir’s system with their 99.7% uptime . “We can’t afford to stop production for filter cleaning, so the DustMaster’s continuous cleaning feature has been a game-changer,” says the plant’s Maintenance Supervisor, Tom Wilson. “It’s also reduced the amount of waste we send to landfills—we now recycle the collected dust back into our metal recovery process.”

EcoSphere Air Technologies is all about sustainability—both in their products and their company ethos. Their “GreenGuard Li” air pollution control system is made from 85% recycled steel, and their filters are reusable (after thermal reactivation), cutting down on waste. But don’t let the eco-friendly focus fool you—this system is a powerhouse.

Their secret weapon? A biofiltration stage that uses naturally occurring bacteria to break down VOCs into harmless byproducts. For plants looking to reduce their carbon footprint, this is a win-win: it eliminates the need for energy-intensive thermal oxidizers. A lithium recycler in Prince Edward Island that aims to be carbon-neutral by 2030 installed GreenGuard Li and saw their carbon emissions ｄｒｏｐ by 15% . “We wanted a pollution control system that aligned with our sustainability goals, and EcoSphere delivered,” says the plant’s Sustainability Director, Emma Thompson. “Plus, the biofilters have a pleasant earthy smell—no more chemical odors wafting from the plant!”

Rounding out our list is UltraClean Systems International, a global player with a strong Canadian presence. Their “MegaClean LX” system is a behemoth, designed for the largest lithium battery recycling plants—those processing 2,500 kg/hour or more. What’s remarkable is its processing capacity: it can handle up to 50,000 cubic meters of air per hour , making it ideal for mega-facilities.

UltraClean also offers unrivaled after-sales support. Their Canadian service team is available 24/7, and they stock replacement parts locally, so downtime is kept to a minimum. A major recycler in Alberta that processes batteries from across Western Canada relies on UltraClean’s system: “When you’re handling this volume of material, you can’t afford to wait for parts to ship from overseas,” says their Plant Director, John McKenzie. “UltraClean’s local support has been invaluable—they’re like an extension of our team.”
