Top 5 Air Pollution Control System Suppliers for Lithium Battery Recycling Plants in France [2025]

Founded in 2008, EcoGuard Systems France has grown from a small engineering firm to a household name in industrial air purification. What sets them apart? Their laser focus on lithium battery recycling-specific challenges. Unlike generalist suppliers, they’ve spent over a decade tweaking their systems to handle the unique cocktail of emissions from battery shredding and thermal treatment.

Their flagship product, the EcoPure-Li Series , is a modular system designed to work with both dry and wet process equipment. It starts with a high-efficiency cyclone separator to catch large particulates (think battery casing fragments), followed by a ceramic filter for fine dust (down to 0.1 microns—smaller than most viruses). But the real star is their proprietary “VOC Trap” technology: a catalytic oxidation unit that breaks down harmful organic compounds into harmless CO₂ and water, even at low temperatures (saving energy compared to traditional incineration-based systems).

What French plant managers love most? EcoGuard’s obsession with compliance. Their systems are pre-certified to meet France’s strict AFNOR NF X 43-300 standards and the EU’s Industrial Emissions Directive (IED), so you won’t waste months on regulatory paperwork. Plus, their Paris-based tech support team offers 24/7 remote monitoring—they can tweak system settings in real time if emissions spike, and send a technician within 48 hours for on-site issues. “We had a sudden increase in nickel emissions during a batch of old laptop batteries,” says Marie Dubois, operations manager at a Lyon-based recycling plant. “EcoGuard’s team logged in, adjusted the filter media, and we were back to compliance in 2 hours. You can’t put a price on that peace of mind.”

Downsides? They’re not the cheapest option—expect to invest 15-20% more upfront than budget suppliers. But with energy savings of up to 30% annually and a 10-year warranty on core components, most clients say it pays for itself within 3 years.

CleanAir Tech SAS made waves in 2019 when they introduced France’s first fully automated air pollution control system for lithium battery recycling. Based in Toulouse (a hub for aerospace and green tech), this supplier prides itself on “innovation without overcomplication.” Their approach? Keep systems simple, scalable, and tailored to small-to-medium plants that might not have the budget for enterprise-level setups.

Their Li-Clean 5000 is a compact, all-in-one unit that’s perfect for plants processing 500-2,500 kg/hour (a common capacity range for mid-sized facilities). It skips the fancy bells and whistles but nails the basics: a multi-stage filtration system that combines bag filters for dust, activated carbon beds for VOCs, and a scrubber for acid gases (like hydrogen fluoride from lithium extraction). What’s clever is their “Plug & Play” design—you can install it in under a week, even if your plant is already operational. No need to halt production for major renovations.

Sustainability is another focus here. CleanAir uses recycled materials for their filter casings and offers a filter recycling program—they’ll pick up used filters and repurpose the metal frames, cutting down on waste. They also partner with local renewable energy providers to power their Paris headquarters, and offset carbon emissions from system manufacturing by investing in reforestation projects in the Loire Valley. For plants aiming for B Corp certification or EU “Green Plant” labels (a big plus for government grants), this green cred is a major selling point.

One thing to note: While the Li-Clean 5000 works great for standard lithium battery recycling, it might need upgrades if you’re processing mixed waste (like batteries with circuit boards or plastic casings). CleanAir does offer add-ons, but they can bump up the cost unexpectedly. Still, for plants focused solely on lithium batteries, this is a solid, no-fuss choice.

AirWorks Eco Solutions is the new kid on the block, but they’ve quickly earned a reputation for bold engineering. Founded in 2017 by ex-Siemens engineers, this Nantes-based startup isn’t afraid to challenge industry norms. Their claim to fame? The AtmosZero-Li , a system that uses electrostatic precipitation (ESP) instead of traditional filters. ESP works by charging particles with electricity and then collecting them on oppositely charged plates—no filter media needed. This means zero downtime for filter changes, a huge win for high-capacity plants.

But ESP alone isn’t enough for lithium battery emissions, so AirWorks paired it with a “plasma scrubber” for acid gases. This high-tech add-on uses ionized gas (plasma) to break down toxic gases like sulfur dioxide and hydrogen chloride into neutral salts, which are then collected as a harmless byproduct (some plants even sell this salt to chemical manufacturers, turning waste into a small revenue stream). It’s a pricier tech, but for plants processing over 2,000 kg/hour, the reduced maintenance and higher efficiency make it worth it.

AirWorks also shines in customization. They don’t just sell you a system—they send a team to audit your plant’s layout, production流程, and even local weather patterns (wind direction affects emissions dispersion, after all). “We had a plant in Marseille where prevailing winds blow toward a residential area,” explains CEO Julien Petit. “We adjusted the system’s fan speed and exhaust stack height to ensure emissions disperse safely, even on windy days. That’s the kind of detail most suppliers miss.”

The catch? ESP systems are sensitive to moisture, so they’re best paired with dry process equipment. If your plant uses wet processes (like acid leaching for metal recovery), you’ll need to add a pre-dryer, which adds cost and complexity. Still, for dry-process plants chasing maximum uptime, AirWorks is hard to beat.

GreenShield Environmental isn’t French—they’re a German firm with a growing footprint in France (thanks to their acquisition of a Lyon-based filter manufacturer in 2022). But don’t let the German roots fool you: they’ve localized their systems to fit French regulations and plant needs. What makes them a top pick? Their focus on total cost of ownership (TCO). While their upfront prices are competitive, their real value lies in long-term savings.

Take their Li-Shield Pro system. It uses a hybrid filtration approach: a primary bag filter for coarse dust, then a HEPA filter for fine particles, and a UV-C light module to neutralize VOCs (no energy-heavy catalytic units here). The UV-C tech is less powerful than catalytic oxidation, but it’s cheaper to run and easier to maintain—perfect for plants watching their energy bills. GreenShield also offers a “Predictive Maintenance” app that tracks filter life, energy usage, and emission levels, sending alerts when parts need replacing. This cuts down on unexpected breakdowns and extends the system’s lifespan by 2-3 years on average.

Another standout feature? Their Air Recycling Mode . Instead of venting filtered air outside, the system cleans it to near-ambient quality and recirculates it back into the plant. This reduces heating/cooling costs (a big deal in France’s chilly winters and hot summers) and lowers fresh air intake requirements. A plant in Strasbourg reported saving €12,000/year on HVAC costs after switching to this mode—more than enough to offset the system’s annual maintenance fees.

GreenShield’s weak spot? Their French support team is still small (about 15 people), so response times can be slower in rural areas. But for plants near major cities (Paris, Lyon, Marseille), their German-engineered reliability and cost-saving features make them a strong contender.

PureAir Innovations is the dark horse on this list—a Parisian startup founded by two former environmental scientists from École Polytechnique. They don’t have the decades of experience of EcoGuard or GreenShield, but they’re disrupting the market with cutting-edge materials science. Their secret weapon? Nano-ceramic filters .

Traditional filters use fiberglass or polyester; PureAir’s filters are made with nano-composite ceramic balls (yes, similar to the ones used in high-tech ball mills, but engineered for air filtration). These tiny balls (about the size of a grain of sand) have microscopic pores that trap particles as small as 0.01 microns, including heavy metals like lithium and cobalt. What’s more, the ceramic material is heat-resistant up to 800°C, so it can handle the high temperatures of battery pyrolysis without degrading.

Their NanoClean-Li System is compact but mighty. It’s designed for small plants (processing 500-1,000 kg/hour) and runs on minimal energy—about the same as a household refrigerator. The nano-ceramic filters last up to 5 years (vs. 6-12 months for standard filters), so you’ll spend less on replacements. Plus, PureAir offers a “Filter Buyback” program: when the filters finally wear out, they’ll recycle the ceramic material into new filters, closing the loop on sustainability.

What really wins over clients, though, is their transparency. PureAir publishes real-time emission data from their installed systems on their website (anonymized, of course), so you can see exactly how well their tech performs in real-world conditions. “We had nothing to hide,” says co-founder Sophie Laurent. “If a system isn’t working as promised, we’d rather fix it than pretend it’s perfect.”

The downside? As a startup, they have limited production capacity—wait times for systems can stretch to 3-4 months. But for small plants willing to wait, the nano-ceramic tech and eco-friendly approach are well worth it.
