Founded in 1995 and headquartered in Tokyo, EcoTech Solutions has built a reputation as a pioneer in tailored air pollution control. What sets them apart is their deep focus on recycling-specific challenges. They don’t just sell “air pollution control system equipment”—they engineer solutions that adapt to the messy, variable conditions of recycling plants.

One of their standout offerings is the air pollution control system for li battery recycling plant , designed to tackle the unique emissions from lithium battery breaking and separation. This system combines high-efficiency particulate air (HEPA) filters for dust, activated carbon beds for volatile organic compounds (VOCs), and catalytic converters for toxic gases like hydrogen fluoride. It’s fully automated, with real-time sensors that adjust airflow based on emission levels—critical for plants processing 500kg to 2,500kg of lithium batteries per hour.

EcoTech also serves lead acid battery recycling plants, circuit board recycling facilities, and even refrigerator/ac recycling operations. Their after-sales support includes on-site training and 24/7 monitoring, ensuring minimal downtime. “We treat each client’s plant as if it were our own,” says CEO Akira Tanaka. “If a filter clogs or a sensor malfunctions, our team is there within hours.”

With roots dating back to 1978, Nippon Clean Air is a household name in Japan’s industrial sector. Based in Osaka, they specialize in heavy-duty “air pollution control machines equipment” built for high-volume operations. Think large-scale lead acid battery recycling plants or metal melting furnaces—environments where emissions are constant and intense.

Their flagship product, the NCAS-5000 Series , is a workhorse electrostatic precipitator (ESP) that removes 99.9% of particulate matter from exhaust streams. It’s a favorite in lead paste reduction rotary furnaces, where lead oxide dust is a major concern. “ESP technology is tried and true, but we’ve upgraded it with smart diagnostics,” explains lead engineer Mei Yamamoto. “Operators can track electrode performance and ash buildup via a tablet, so maintenance is proactive, not reactive.”

Beyond ESPs, Nippon Clean Air offers bag filters, wet scrubbers, and hybrid systems for mixed emissions. They’ve recently expanded into air pollution control for lithium battery recycling, adapting their scrubbers to neutralize hydrofluoric acid—a byproduct of lithium ore processing. Their client list includes major recycling conglomerates like Japan Metals & Chemicals Co., Ltd., a testament to their reliability.

Tokyo Environmental Technologies (TET) has made a name for itself by merging cutting-edge tech with user-friendly design. Founded in 2001, this Yokohama-based firm focuses on “small but mighty” systems ideal for mid-sized recycling plants—think circuit board recycling lines with 500-2000kg/hour capacity or cable recycling operations.

Their CompactClean Series is a hit among smaller facilities. These modular systems combine a pre-filter for large particles, a HEPA filter for fine dust, and a UV-C light module for VOCs—all in a footprint smaller than a standard pallet. “Many recycling plants are tight on space,” says sales director Yuki Sato. “Our CompactClean fits into corners, but it doesn’t skimp on performance. It’s perfect for a circuit board recycling plant with dry separator, where space is at a premium.”

TET also excels in customer collaboration. They offer free on-site assessments, where their engineers map out emission hotspots (like near a shredder or pre-chopper) and design a system that targets those areas directly. This personalized approach has earned them repeat business from family-owned recycling yards and multinational corporations alike.

Osaka Air Quality Engineering (OAQE) is all about innovation—especially when it comes to tough-to-treat emissions. Founded in 2003, this firm has carved a niche in handling “sticky” pollutants, like the sulfur dioxide from lead acid battery paste reduction or the resin fumes from plastic pneumatic conveying systems.

Their BioScrubber X-7 is a game-changer for sulfur-heavy operations. Unlike traditional chemical scrubbers that use caustic solutions, the BioScrubber uses naturally occurring bacteria to break down sulfur dioxide into harmless sulfates. “It’s eco-friendly and cost-effective,” explains R&D head Hiroshi Nakamura. “No more buying and disposing of chemicals—just add nutrients to the bacteria tank monthly.”

OAQE also partners with lithium battery recycling plants, offering a hybrid system that combines wet scrubbing for acid gases and plasma oxidation for persistent VOCs. Their systems are built to handle fluctuations in throughput, making them ideal for plants that process both lithium and lead acid batteries. “Recycling isn’t a steady process—some days you’re breaking 500kg of batteries, other days 2,000kg,” Nakamura adds. “Our systems don’t panic when the load spikes.”

Kyoto Eco-Industrial Systems (KEIS) takes a holistic approach to sustainability. Founded in 2008, this Kyoto-based supplier doesn’t just control emissions—they help clients turn waste into resources. Their air pollution control systems often integrate with heat recovery units, capturing waste heat from emissions to preheat incoming materials or power plant machinery.

For example, their HeatRecover APC System is designed for metal melting furnaces and medium frequency electricity furnaces. As the system filters particulates and gases, it uses a heat exchanger to capture exhaust heat, which is then used to warm the furnace’s intake air. “We’ve seen clients reduce their natural gas use by 15% just by reusing this heat,” says sustainability director Yui Tanaka.

KEIS also shines in the lithium ore extraction and tailing ore extraction sectors, where dust control is critical. Their dry electrostatic precipitators for mining operations capture fine ore dust with 99.8% efficiency, preventing it from escaping into surrounding communities. “In Kyoto, we live by the principle of ‘mottainai’—not wasting anything,” Tanaka adds. “That includes waste heat, waste energy, and even waste air.”

While many suppliers focus on high-tech urban plants, Hokkaido Pollution Control Equipment (HPCE) specializes in rugged, cold-climate systems. Founded in 1982 in Sapporo, they understand the unique challenges of recycling operations in Hokkaido and northern Japan—where freezing temperatures can clog filters, freeze scrubber liquids, and slow down equipment.

Their ArcticShield Series is built to withstand -20°C winters. It includes heated filter housings to prevent ice buildup, insulated scrubber tanks with thermostats, and even heated sensor probes to ensure accurate readings in cold weather. “A recycling plant in Asahikawa once told us their old system froze solid every December,” recalls sales manager Kenjiro Ito. “We installed ArcticShield, and they haven’t had a winter shutdown since.”

HPCE also serves the fishing and maritime recycling sectors, where salt air adds corrosion to the mix. Their systems use marine-grade stainless steel and anti-corrosion coatings, ensuring longevity in harsh environments. “We don’t just meet standards—we exceed them for the conditions our clients face,” Ito says.

Nagoya Environmental Engineering Works (NEEW) is all about scalability. Founded in 1998, this Nagoya-based firm caters to both small workshops and large industrial plants, with systems ranging from compact units for a 500kg/hour circuit board recycling plant to mega-systems for 2,000kg/hour lead acid battery breaking lines.

Their ModuAir Series is a modular system that grows with your business. Start with a basic HEPA filter and carbon bed for a small cable recycling machine, then add a scrubber or plasma unit as you expand into lithium batteries. “We’ve had clients start with a 300kg/hour setup and scale to 2,500kg/hour in three years—all using the same core ModuAir components,” explains project manager Aiko Suzuki.

NEEW also offers turnkey installation, handling everything from permits to training. “Many recycling plant owners are experts in material recovery, not air systems,” Suzuki adds. “We take the stress out of compliance by managing the entire process—so they can focus on what they do best.”

Fukuoka Air Purification Systems (FAPS) has made a name for itself in the electronics recycling sector, where fine dust and toxic metals like lead and cadmium are major concerns. Founded in 2001, this Fukuoka-based supplier works closely with circuit board recycling plants, CRT recycling facilities, and motor stator cutter operations.

Their DustMaster Pro is a high-efficiency cyclone + HEPA system designed for dry process equipment, like circuit board shredders and compact granulators with dry separators. It captures 99.97% of particles as small as 0.3 microns—critical for meeting Japan’s strict emissions limits for heavy metals. “Circuit board dust is invisible but dangerous,” says technical director Takashi Mori. “Our systems ensure workers aren’t breathing it in, and nearby communities aren’t exposed.”

FAPS also offers specialized filters for nano ceramic ball production and microcrystalline ceramic ball manufacturing, where ultra-fine ceramic dust can damage equipment and lungs. “We test every filter in our lab before shipping, simulating the exact dust conditions of our clients’ plants,” Mori adds. “Quality control isn’t optional—it’s our promise.”

Sendai Clean Tech Solutions (SCTS) is a rising star, founded in 2010 after the Tohoku earthquake to support regional recycling and reconstruction. Today, they’re known for their affordable, easy-to-maintain air pollution control systems—perfect for small to mid-sized recyclers who need compliance without breaking the bank.

Their BudgetGuard Series includes basic but reliable bag filters, cyclones, and scrubbers priced 20-30% lower than premium brands. “We cut costs by using standardized components and skipping fancy bells and whistles—like touchscreens or remote monitoring—unless clients ask for them,” says founder Yuki Watanabe. “A small scrap cable stripper operation doesn’t need the same system as a 2,000kg/hour lithium plant, and we respect that.”

Despite the lower price point, SCTS doesn’t compromise on safety. All their systems meet Japan’s Air Pollution Control Act standards, and they offer free compliance consultations to help clients navigate paperwork. “We started this company to help local businesses recover after the earthquake,” Watanabe adds. “That mission still drives us—we want every recycler, no matter how small, to afford clean air.”

Rounding out our list is Hiroshima Green Engineering Group (HGEG), a multi-disciplinary firm founded in 1990 that combines air pollution control with water treatment and waste management. This “one-stop shop” approach is ideal for recycling plants that need integrated environmental solutions—like a lead acid battery recycling plant that requires both air emission control and wastewater treatment.

Their EcoCycle Package bundles an air pollution control system (including scrubbers and filters) with a water process equipment setup, ensuring that emissions and wastewater are treated in sync. For example, the sulfuric acid captured by the air scrubber can be neutralized using alkaline wastewater from battery breaking, reducing chemical use and waste. “It’s about closing the loop,” explains environmental engineer Maki Kato. “Why treat air and water separately when they’re part of the same process?”

HGEG also specializes in air pollution control for “mixed” recycling plants that handle everything from cables to refrigerators to CRTs. Their systems are flexible enough to switch between treating plastic fumes, refrigerant gases, and lead dust—all with minimal reconfiguration. “Recycling is messy, and plants don’t stick to one material,” Kato adds. “Our systems are just as adaptable as our clients.”
