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

When it comes to combining German engineering precision with eco-friendly innovation, EcoTech Solutions GmbH is hard to beat. Founded in 2005 in Munich, this family-owned firm has quietly become a go-to for European recycling plants, thanks to its modular air pollution control system for li battery recycling plant setups.

What really sets EcoTech apart is its “MultiStage™” approach. Imagine a system that starts with a high-efficiency cyclone to catch large dust particles, then moves to a baghouse filter with Teflon-coated bags (perfect for sticky lithium compounds), and finishes with a catalytic oxidizer that zaps VOCs and HF into harmless CO2 and water. It’s like a Swiss Army knife for air purification, and it’s fully customizable based on a plant’s throughput—whether it’s a small-scale operation handling 500 kg/h or a mega-plant processing 2,500 kg/h of batteries.

Take their work with Berlin-based LiRecycle GmbH, a leading recycler. When LiRecycle expanded its operations in 2024, they needed a system that could handle the increased emissions from their new shredding line. EcoTech installed a MultiStage™ setup with real-time monitoring via their EcoVision™ software, which tracks pollutant levels and adjusts fan speeds automatically to save energy. The result? Emissions of HF dropped to 0.5 mg/m³—well below the EU’s 2 mg/m³ limit—and LiRecycle saw a 15% reduction in energy costs compared to their old system.

EcoTech’s secret weapon? They don’t just sell equipment—they partner with clients. Their team of engineers spends weeks on-site, mapping out every emission point, simulating different scenarios, and even training staff on maintenance. As one plant manager in Spain put it: “Working with EcoTech feels like having an in-house air quality expert.”

Headquartered in Lyon, CleanAir Europe has been a staple in the European environmental tech scene since 1998, but it’s their recent pivot to lithium battery recycling that’s turning heads. While many suppliers adapt existing systems, CleanAir built their air pollution control system equipment from the ground up specifically for the unique challenges of battery recycling.

Case in point: their LiPurge™ gas scrubber. Traditional scrubbers use water to trap gases, but lithium battery emissions often include hydrofluoric acid, which can react with water to form corrosive byproducts. CleanAir’s solution? A dry scrubbing system that uses activated alumina pellets to吸附 (adsorb) HF and other acid gases. The pellets are then regenerated on-site, reducing waste and operational costs. It’s a game-changer for plants that want to avoid the hassle of wastewater treatment—especially important in water-scarce regions like southern Europe.

Another standout feature is their SmartFilter™ dust collection system. Unlike standard baghouses that require frequent filter changes (a messy, time-consuming job), SmartFilter uses ultrasonic sensors to detect when filters are clogged and automatically cleans them with pulses of compressed air. This means less downtime and longer filter life—up to 18 months, compared to the industry average of 6–9 months.

CleanAir’s portfolio includes a project with Portugal’s GreenVolt Recycling, which operates one of Europe’s largest lithium battery recycling plants (2,000 kg/h capacity). GreenVolt needed a system that could handle the variable emissions from processing both EV batteries and small consumer electronics. CleanAir delivered a hybrid setup: LiPurge™ for acid gases, SmartFilter™ for dust, and a heat recovery unit that captures waste heat from the oxidizer to warm the plant in winter. The result? GreenVolt’s carbon footprint dropped by 8% in the first year, and their maintenance team now spends 50 fewer hours per month on filter changes.

“CleanAir gets it,” says GreenVolt’s Operations Director, Maria Almeida. “They don’t just ask, ‘What’s your emission limit?’ They ask, ‘What keeps you up at night?’ For us, it was downtime and waste. Their system solved both.”

GreenCycle Systems might be the new kid on the block (founded in 2015 in Birmingham), but don’t let their youth fool you. This British startup has made a name for itself by focusing on one thing: energy efficiency. In an industry where air pollution control systems can account for 20–30% of a plant’s energy use, GreenCycle’s “EcoSave™” technology is a breath of fresh air—literally.

Here’s how it works: Most systems use large fans to pull air through filters and scrubbers, which guzzles electricity. GreenCycle’s EcoSave™ uses variable-speed drives and aerodynamic fan blades designed with computational fluid dynamics (CFD) to reduce energy consumption by up to 40%. It’s like swapping a gas-guzzling truck for a hybrid car—same job, but way less fuel.

But GreenCycle isn’t just about saving energy; they’re about data, too. Their AirGuard™ platform connects to sensors throughout the recycling line, collecting data on temperature, pressure, and pollutant levels. This data is then fed into a machine learning algorithm that predicts when components might fail (like a filter reaching the end of its life) and even suggests process tweaks to reduce emissions. For example, if the algorithm notices higher dust levels during morning shifts, it might recommend adjusting the shredder’s speed to minimize particle generation.

Take their partnership with Scotland’s NorthVolt Recycling (no relation to the battery manufacturer). NorthVolt’s Dundee plant processes around 800 kg/h of lithium batteries, and they were struggling with high energy bills from their old air system. GreenCycle installed an EcoSave™ setup with AirGuard™, and within six months, NorthVolt’s energy costs dropped by £32,000 annually. The AirGuard™ alerts also helped them catch a failing fan bearing before it caused a shutdown—saving an estimated £50,000 in downtime.

GreenCycle’s founder, Dr. James Wright, a former environmental engineer at Imperial College London, sums it up: “We started GreenCycle because we saw too many recycling plants paying the price—literally—for outdated air systems. Our goal is to make clean air affordable for everyone, not just the big players.”

AirPure Technologies, based in Rotterdam, has a reputation for thinking outside the box—or rather, outside the plant. This Dutch firm specializes in “closed-loop” air pollution control, meaning they design systems that not only clean emissions but also recover valuable resources from them. For lithium battery recyclers, that’s a game-changer.

Let’s talk about their LiCapture™ technology. When lithium batteries are processed, some of the lithium in the dust can be lost to the air pollution control system. AirPure’s LiCapture™ uses electrostatic precipitation (think of a giant air purifier on steroids) to capture these fine lithium particles, which are then collected and sold back to battery manufacturers. It’s like turning air pollution into profit. One plant in Belgium reported recovering 20 kg of lithium per month using LiCapture™—adding €1,200 to their monthly revenue stream.

But AirPure doesn’t stop there. Their “ZeroWaste™” scrubber system uses a recyclable sorbent material to trap acid gases like HF. Once saturated, the sorbent is sent to AirPure’s own recycling facility in Amsterdam, where the HF is extracted and reused in industrial processes (like metal plating), and the sorbent is regenerated. It’s a closed loop that eliminates the need for landfilling spent sorbents—a huge win for circular economy goals.

AirPure’s work with Amsterdam-based RecycleLi is a prime example. RecycleLi runs a 1,000 kg/h plant focused on “urban mining” (recovering metals from e-waste and batteries). They wanted a system that aligned with their zero-waste mission, so AirPure installed LiCapture™ and ZeroWaste™. The results? RecycleLi now diverts 95% of its air pollution control waste from landfills, and the recovered lithium has become a small but steady revenue stream. “It’s not just about compliance anymore,” says RecycleLi’s CEO, Anna de Jong. “It’s about creating value from every step of the process, and AirPure gets that.”

With Europe’s focus on circular economy policies, AirPure is poised to become even more popular. Their systems aren’t cheap—initial costs are about 10–15% higher than standard setups—but the ROI from resource recovery often offsets the difference within two to three years.

Rounding out our list is EuroEnvitech Engineering, an Italian firm with a knack for designing compact, high-performance systems—perfect for Europe’s many urban recycling plants where space is at a premium. Founded in Milan in 1990, EuroEnvitech has spent decades refining its “SpaceSaver™” line, and their latest offering for lithium battery recycling is a hit.

Imagine a system that does the work of three separate units (dust collector, scrubber, oxidizer) but takes up 40% less floor space. That’s the SpaceSaver™. EuroEnvitech achieves this by stacking components vertically and using modular designs that fit through standard doorways—no need for cranes or拆墙 (wall demolition) during installation. For plants in cities like Paris or Rome, where real estate is expensive, this is a lifesaver.

But don’t let the small size fool you—SpaceSaver™ packs a punch. Their latest model, the SS-2500, can handle emissions from a 2,500 kg/h lithium battery recycling line, with a dust removal efficiency of 99.97% and HF removal of 99.9%. It also includes a built-in heat exchanger that captures waste heat from the oxidizer to preheat incoming air, cutting energy use by 20%.

Take their project with Rome-based EcoBatt S.r.l., a recycler operating in a former industrial warehouse in the city’s outskirts. EcoBatt needed to expand its recycling capacity but had limited space for new equipment. EuroEnvitech installed a SpaceSaver™ SS-1500 in just three weeks (half the time of a standard system), allowing EcoBatt to boost throughput from 800 kg/h to 1,500 kg/h without expanding their facility. “We thought we’d have to move to a new location,” says EcoBatt’s Plant Manager, Marco Rossi. “EuroEnvitech showed us we could grow without leaving.”

EuroEnvitech also prides itself on its after-sales support. With service centers in Milan, Madrid, and Warsaw, they offer 24/7 technical support and can dispatch a technician to most European plants within 24 hours. For busy recyclers, that peace of mind is priceless.
