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

Founded in 2008 and based in Hangzhou, CleanAir Tech has built a reputation as a pioneer in air pollution control for the recycling industry. What makes them stand out? They don’t just sell equipment—they design custom air pollution control system for li battery recycling plant that adapt to each facility’s unique workflow. Their systems combine multi-stage filtration (bag filters, activated carbon adsorption, and catalytic oxidation) to tackle everything from fine dust to harmful gases like sulfur dioxide.

One of their most impressive projects was a 2,000 kg/h lithium battery recycling plant in Jiangsu. Before installing CleanAir’s system, the plant struggled with dust emissions exceeding 35 mg/m³. Post-installation? Emissions dropped to a staggering 8 mg/m³—well below China’s national standard of 20 mg/m³. “We used to have workers complaining about eye irritation,” said the plant manager. “Now, even during peak hours, the air in the workshop feels clean.”

Headquartered in Shanghai, GreenGuard has been a key player since 2010, focusing on sustainable solutions for high-pollution industries. Their claim to fame? They were one of the first in China to integrate dry process equipment into air pollution control systems for lithium battery recycling. Dry processes eliminate the need for large water tanks, making their systems ideal for water-scarce regions or facilities looking to cut wastewater treatment costs.

Take their work with a lithium battery recycling plant in Xinjiang, where water resources are limited. GreenGuard installed a dry-type air pollution control system that handled 1,500 kg/h of battery waste without a single ｄｒｏｐ of process water. The result? The plant not only met emission standards but also reduced its water consumption by 80% compared to similar facilities using wet scrubbers. “In Xinjiang, water is gold,” the plant’s environmental director noted. “GreenGuard’s system let us expand production without worrying about water shortages.”

Based in Shenzhen’s high-tech zone, EcoFlow has made a name for itself with cutting-edge air pollution control machines equipment designed specifically for large-scale lithium battery recycling plants (1,500 kg/h and above). Their systems are known for handling extreme pollutant loads—critical for facilities processing battery black mass, which releases high concentrations of heavy metals and fluorides.

A recent project in Hubei involved a plant processing 2,500 kg/h of lithium batteries—one of the largest in central China. EcoFlow’s system was tasked with controlling emissions from both the shredding and pyrolysis stages. After six months of operation,第三方检测 showed that heavy metal emissions (like nickel and cobalt) were consistently below 0.05 mg/m³, and fluoride levels stayed under 1 mg/m³. “We were worried about meeting the new regional emission standards,” said the plant’s operations chief. “EcoFlow’s system didn’t just meet them—it crushed them.”

BlueSky, founded in 2012 and located in Nanjing, prides itself on “turnkey solutions.” For lithium battery recyclers, this means they handle everything from initial site assessment to system installation and staff training—no need to coordinate with multiple vendors. Their air pollution control system equipment is modular, so plants can start small and expand as their capacity grows.

A startup recycler in Anhui is a perfect example. When they first opened, they processed 500 kg/h of lithium batteries and installed BlueSky’s basic 2-module system. Two years later, as demand grew, they added 3 more modules—all while keeping the plant running. “We didn’t have to pause production for a single day during the upgrade,” the CEO recalled. “BlueSky’s team worked around our night shifts to install the new modules, and the system was fully operational by morning.” Today, the plant processes 2,000 kg/h, and their air pollution control system still runs at 98% efficiency.

With roots in the chemical engineering sector, PureCycle (based in Wuhan) brings a unique perspective to air pollution control. They specialize in integrating wet process equipment with advanced water treatment loops, making their systems ideal for plants that need to handle both air and water pollution in one go. For lithium battery recycling, this is a game-changer—since wet scrubbers generate wastewater that’s often contaminated with heavy metals.

A lithium battery recycling plant in Sichuan faced a dual problem: high air emissions and strict local water discharge regulations. PureCycle installed a wet scrubber system linked to their ClosedLoop water treatment. The result? The plant’s air emissions dropped to 12 mg/m³, and they reduced freshwater intake by 90%. “We used to spend ¥80,000 monthly on wastewater disposal,” said the plant’s operations manager. “Now, we only generate a small amount of sludge, and our water bill is a fraction of what it was.”

AirClear has built its brand on affordability without compromising quality. Targeting mid-sized lithium battery recycling plants (500–1,500 kg/h), they offer pre-engineered air pollution control system equipment that can be delivered and installed in as little as 30 days—perfect for facilities on tight timelines. Their systems may not have all the bells and whistles of high-end models, but they’re reliable and easy to maintain.

A family-owned recycler in Henan needed to upgrade their air pollution control system to meet new regional regulations but had a limited budget and no in-house engineering team. AirClear stepped in with a QuickFit system sized for 800 kg/h. The installation took just 28 days, and the plant’s emissions dropped from 45 mg/m³ to 15 mg/m³. “We were worried we’d have to shut down for months,” said the owner. “AirClear’s team had us up and running before our compliance deadline, and their manual is so simple even our night shift crew can troubleshoot basic issues.”

EnviroMax, based in Chengdu, has carved a niche in serving remote or hard-to-reach locations. Their air pollution control machines equipment is designed to be compact and transportable, with modular components that can be shipped via truck to mountainous or rural areas. This is crucial for lithium battery recycling plants that are often built near mining sites or EV manufacturing hubs in less urban regions.

A lithium battery recycling pilot plant in a remote county in Gansu faced a logistical nightmare: large equipment couldn’t be transported over the narrow mountain roads. EnviroMax’s MiniGuard system was the solution. The components were shipped in small trucks, assembled on-site in 5 days, and handled 300 kg/h of battery waste with emissions under 18 mg/m³. “We thought we’d have to build in a city 200 km away,” said the project lead. “EnviroMax made it possible to set up right next to our raw material source.”

FreshAir, a rising star from Qingdao, differentiates itself with AI-powered air pollution control. Their systems use machine learning algorithms to predict pollutant spikes (common during batch processing of lithium batteries) and adjust settings proactively. This “predictive control” ensures emissions never exceed limits, even when the plant’s input material varies.

A large recycler in Guangdong with inconsistent feedstock (mixing different battery types) was struggling with emission fluctuations. FreshAir installed their AI-Guard system, which learned the plant’s production patterns within 2 weeks. Since then, the plant has maintained a steady emission level of 10–12 mg/m³, even when processing mixed battery batches. “We used to have to manually adjust settings 5–6 times a day,” said the control room operator. “Now, the system does it all—we just monitor the screen.”

CleanWave, based in Zhengzhou, specializes in low-noise air pollution control systems—an often-overlooked factor in facility design. For lithium battery recycling plants located near residential areas, noise pollution can be as big a problem as air pollution. CleanWave’s systems are engineered to operate at under 75 dB (about the noise level of a vacuum cleaner), even at full capacity.

A lithium battery recycling plant in a suburban area of Shanghai was facing complaints from neighbors about loud fans. CleanWave replaced their old system with a SilentFlow setup, bringing noise levels down from 92 dB to 70 dB. “The difference is night and day,” said the plant manager. “We haven’t had a single complaint since the upgrade, and our workers in the adjacent workshop no longer need ear protection.”

Rounding out our list is GlobalEco, a supplier with a focus on international standards. Their air pollution control system for li battery recycling plant is certified by both China’s environmental agencies and the EU’s CE mark, making them a top choice for Chinese recyclers looking to export recycled materials to Europe or North America.

A lithium battery recycler in Suzhou wanted to export recycled cobalt to European automakers, which required meeting EU emission standards. GlobalEco installed a system that not only controlled emissions to EU levels but also provided automated compliance reports in English. “The certification process was smooth because GlobalEco’s system already met all the EU’s requirements,” said the export manager. “We now supply to three European car brands, and the air pollution control system was a key selling point.”
