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

1. GreenTech Environmental Systems

First off, GreenTech Environmental Systems has been a big name in China’s environmental tech scene since 2010. They’ve made a name for themselves by focusing specifically on air pollution control for industrial recycling—lithium batteries included. What’s really stand-out here is their commitment to custom solutions. No two recycling plants are the same, right? Some might process 500 kg/hour, others 2,500 kg/hour. GreenTech doesn’t just sell a one-size-fits-all system; they sit down with you, analyze your plant’s layout, throughput, and the specific pollutants you’re dealing with, and then design a system that fits like a glove.

Their star product for lithium battery recycling? The “EcoPurify LP Series,” which is basically an all-in-one air pollution control system tailored for lithium battery recycling plants. Let’s break it down: it starts with a pre-filter to catch large dust particles (think battery casing fragments or electrode materials), then moves to a high-efficiency bag filter for finer dust. But here’s the kicker: they’ve added a catalytic oxidation unit to tackle those tricky VOCs released during battery shredding and pyrolysis. And to top it off, a活性炭吸附 tower (activated carbon adsorption tower) to capture any remaining odors or trace pollutants. What’s impressive is the data: one of their systems installed at a major recycling plant in Jiangsu Province (processing 1,500 kg/hour) has consistently kept emissions well below national standards—particulate matter at 5 mg/m³ (vs. the 10 mg/m³ limit) and VOCs at 15 mg/m³ (way under the required 50 mg/m³).

Another thing to love about GreenTech? Their after-sales service. They don’t just hand over the system and disappear. They offer 24/7 technical support, regular maintenance check-ups, and even staff training to make sure your team knows how to keep the system running smoothly. For plants that are new to lithium battery recycling, that kind of support is gold.

2. EcoClean Engineering Co., Ltd.

If there’s one supplier that’s been making waves with cutting-edge tech, it’s EcoClean Engineering. Founded in Shanghai in 2015, they’ve quickly risen through the ranks by leaning into smart, energy-efficient systems. Their claim to fame? The “SmartAire LC System,” which uses IoT (Internet of Things) integration to monitor and adjust air pollution control in real time—something that’s a game-changer for high-throughput plants.

Here’s how it works: sensors placed throughout the recycling line (shredders, separators, furnaces) continuously track pollutant levels—temperature, dust concentration, VOCs, you name it. That data feeds into a central control panel, which automatically adjusts fan speeds, filter cleaning cycles, and catalytic oxidation temperatures. So if there’s a sudden spike in dust from a batch of particularly “dirty” batteries, the system ramps up filtration power without waiting for a human operator to notice. It’s like having a 24/7 air quality watchdog on-site.

EcoClean’s system also shines when it comes to energy savings. Traditional air pollution control systems can guzzle electricity, but their SmartAire LC uses variable frequency drives (VFDs) on fans and pumps, which adjust energy use based on actual demand. One customer in Guangdong reported a 22% ｄｒｏｐ in energy costs compared to their old, non-smart system. Plus, the modular design makes it easy to scale up. If you start with a 500 kg/hour plant and later expand to 1,000 kg/hour, you can add modules instead of replacing the entire system—saving time and money.

Real-world example: A lithium battery recycling plant in Zhejiang that switched to EcoClean’s SmartAire LC in 2024 now handles 2,000 kg/hour of battery waste. Their emissions? Particulate matter at 3 mg/m³, VOCs at 10 mg/m³, and zero complaints from nearby communities. For plants looking to future-proof their operations, EcoClean is hard to beat.

3. AirPure Solutions

AirPure Solutions might be the new kid on the block (founded in 2018), but they’ve already earned a spot on this list by focusing on affordability without skimping on quality. Let’s face it: setting up a lithium battery recycling plant is pricey enough. Many smaller or mid-sized plants don’t have the budget for a top-of-the-line, fully custom system. AirPure saw that gap and filled it with their “CompactClean Series”—a pre-engineered, plug-and-play air pollution control system that’s designed for plants processing 500 to 1,500 kg/hour.

Don’t let the “pre-engineered” label fool you, though. The CompactClean Series still packs a punch. It combines a cyclone separator for coarse dust removal, a cartridge filter for fine particles (with a self-cleaning feature using compressed air to shake off dust buildup), and a UV photolysis unit to break down VOCs. It’s not as fancy as GreenTech’s catalytic oxidation, but for smaller plants, it gets the job done—and at a fraction of the cost. AirPure estimates their systems are 30-40% cheaper than fully custom options, making them a hit with startups and regional recycling facilities.

What really wins people over, though, is how easy they are to install and maintain. The system comes pre-assembled in modules, so setup takes just 2-3 days instead of weeks. And maintenance? Simple enough that your on-site technicians can handle it with basic training—no need to call in specialists every time. A plant in Sichuan that processes 800 kg/hour of lithium batteries has been using the CompactClean Series for over a year now, and they report emissions well within standards: particulate matter at 7 mg/m³, VOCs at 35 mg/m³. For a budget-friendly option that doesn’t compromise on compliance, AirPure is a solid pick.

4. EnviroGuard Technologies

EnviroGuard Technologies has been around since 2005, but they’ve recently pivoted hard into lithium battery recycling after seeing the sector’s boom. What sets them apart is their focus on “end-to-end” air pollution control—meaning they don’t just handle the exhaust from shredders or separators; they cover the entire plant. From the battery dismantling area (where fine dust and fumes start) to the pyrolysis and smelting stages (where VOCs and heavy metals like lithium and cobalt might be released), EnviroGuard designs systems that capture pollutants at the source, not just at the final exhaust stack.

Their flagship offering for lithium battery plants is the “EnviroShield Pro,” which includes local exhaust ventilation (LEV) hoods over each processing station, ductwork tailored to minimize pressure loss, and a central treatment system with multiple stages: electrostatic precipitators (for ultra-fine dust), activated carbon beds (for VOCs and heavy metal vapors), and a wet scrubber for acid gases (like hydrogen fluoride, which can be a byproduct of lithium battery processing). It’s overkill for some small plants, but for large-scale operations (2,000+ kg/hour), it’s a lifesaver.

Case in point: A major recycling facility in Shandong that processes 2,500 kg/hour of lithium batteries partnered with EnviroGuard in 2023. After installation, their emissions dropped to near-zero for heavy metals (lithium, cobalt, nickel all below detection limits) and particulate matter at 2 mg/m³. The plant even earned a “Green Factory” certification from China’s Ministry of Industry and Information Technology—no small feat. If your plant is aiming for the highest environmental standards or needs to comply with strict local regulations (looking at you, Beijing and Shanghai), EnviroGuard’s EnviroShield Pro is worth the investment.

5. CleanAir Engineering Group

Last but definitely not least, CleanAir Engineering Group rounds out our list with a focus on sustainability—both for the planet and for your bottom line. They’re all about energy recovery and waste reduction in their air pollution control systems. Here’s the idea: when you treat polluted air, especially with processes like catalytic oxidation or thermal incineration, a lot of heat is generated. CleanAir captures that heat and redirects it back into the plant—for heating water, preheating raw materials, or even powering other equipment. It’s a win-win: lower energy bills and a smaller carbon footprint.

Their “HeatRecycle HC System” is a prime example. It uses a regenerative thermal oxidizer (RTO) to destroy VOCs at high temperatures (over 800°C), but instead of letting that heat go to waste, it uses ceramic heat exchangers to recover up to 95% of it. That recovered heat can then be used to preheat the incoming polluted air, reducing the energy needed to reach oxidation temperatures. For a plant processing 1,500 kg/hour, CleanAir estimates this can cut energy costs by 30-40% annually. That’s a huge saving over time, even if the upfront cost is higher.

CleanAir also prides itself on using eco-friendly materials in their systems—like recyclable steel for ductwork and activated carbon made from sustainable coconut shells instead of coal. A plant in Hubei that switched to CleanAir’s HeatRecycle HC in 2024 reports not only meeting emissions standards (particulate matter 4 mg/m³, VOCs 8 mg/m³) but also saving over ¥150,000 per year on energy. For companies that want to align their operations with both environmental compliance and sustainability goals, CleanAir is a top contender.
