Top 5 Lead Refiner Suppliers in Japan [2025]

1. Nippon LeadTech Co., Ltd.

Founded in 1985, Nippon LeadTech has grown from a small Osaka-based workshop to a global leader in lead refining technology. With over 35 years of experience, they’ve built a reputation for blending time-tested engineering with next-gen innovation. What truly sets them apart is their unwavering focus on lead refinery machine equipment that doesn’t just meet industry standards—it redefines them.

Core Technologies & Products

Nippon LeadTech’s flagship product, the “LeadPro X9 Series,” is a game-changer for high-volume recycling facilities. This continuous lead refining system can process up to 5 tons of scrap lead per hour, boasting a 99.97% purity rate—one of the highest in the industry. The secret? Their patented “Multi-Stage Pyrolysis” technology, which uses precise temperature control to separate impurities without releasing harmful emissions. But it’s not just about the machines; Nippon LeadTech integrates air pollution control system equipment directly into their refining lines, ensuring that even trace pollutants are captured and neutralized. For example, their “EcoShield 3000” filtration system reduces sulfur dioxide emissions by 98% compared to conventional setups, making it a favorite among plants in eco-sensitive regions.

Sustainability at the Core

Japan’s Ministry of Environment awarded Nippon LeadTech the “Green Innovation Prize” in 2024 for their efforts to minimize energy consumption. The LeadPro X9 uses 30% less electricity than competitors, thanks to a heat recovery system that repurposes excess thermal energy to power pre-processing stages. “We don’t just build machines—we build ecosystems,” says Takeshi Mori, the company’s chief sustainability officer. “Our clients aren’t just buying equipment; they’re investing in a future where recycling is as profitable as it is responsible.”

Client Success Stories

Takeo Recycling, a mid-sized facility near Nagoya, upgraded to the LeadPro X9 in 2023. Within six months, their lead output increased by 22%, while operational costs dropped by 18%. “The precision is incredible,” says Yuki Tanaka, Takeo’s plant manager. “We used to spend hours manually sorting impurities; now the system does it automatically. And the air quality improvements? Our workers no longer need heavy respirators during shifts.” Internationally, Nippon LeadTech has made waves in Southeast Asia, where their compact “MiniLead” series is helping small-scale recyclers meet Japan-level emission standards without breaking the bank.

2. EcoRecycle Japan Ltd.

If Nippon LeadTech is the “engine” of Japan’s lead recycling industry, EcoRecycle Japan is its “architect.” Founded in 2001, this Tokyo-based firm specializes in end-to-end recycling solutions, with a particular focus on lead acid battery recycling equipment . What makes them unique is their ability to design custom workflows that turn complex waste streams—like old car batteries or industrial lead scrap—into high-purity lead ingots with minimal manual intervention.

From Waste to Wealth: The Complete Cycle

EcoRecycle’s “BatteryCycle 5000” system is a marvel of integration. It starts with a hydraulic cutter that safely breaks down lead acid batteries, separating plastic casings, acid electrolytes, and lead plates in one seamless step. The lead plates then move to a shredder, where they’re reduced to small chips before entering a smelting furnace. Here’s where EcoRecycle truly shines: their proprietary “AcidGuard” technology neutralizes battery acid on-site, converting it into sodium sulfate—a valuable byproduct used in fertilizers—instead of sending it to landfills. But the star of the show is their use of filter press equipment to process wastewater from the acid neutralization stage. The “PressMax 400” filter press removes 99.9% of solids, allowing treated water to be reused in the facility, cutting water consumption by 60%.

Innovation for Smaller Operators

While many suppliers focus on large plants, EcoRecycle hasn’t forgotten small and medium enterprises (SMEs). Their “CompactCycle 1000” is a scaled-down version of the BatteryCycle 5000, designed for facilities processing 500–1,000 batteries per day. “SMEs are the backbone of recycling in Japan,” explains Aiko Nakamura, EcoRecycle’s sales director. “They often struggle with budget constraints and limited space, so we engineered the CompactCycle to fit in a 300 sq.m. area and pay for itself in under two years through savings on waste disposal and raw material costs.”

Global Reach, Local Impact

EcoRecycle’s most ambitious project to date is a partnership with the Thai government to build 10 recycling hubs across the country by 2026. Each hub will use the BatteryCycle 5000 to process over 100,000 tons of lead acid batteries annually, reducing Thailand’s reliance on imported lead by 40%. “Working with EcoRecycle was a no-brainer,” says Dr. Supaporn Wongwanich, head of Thailand’s Department of Industrial Works. “Their equipment meets Japan’s strict JIS standards, but they were also willing to adapt it to our local waste composition—like higher levels of dirt and debris in batteries. That flexibility is priceless.”

3. Tokyo Metallurgical Systems (TMS)

Tokyo Metallurgical Systems isn’t just a supplier—it’s a pioneer. Founded in 1968, TMS has been at the forefront of metallurgical innovation for over half a century, and their foray into lead recycling has been nothing short of revolutionary. What makes TMS stand out is their cross-industry expertise: they’ve leveraged decades of experience in steel and aluminum processing to develop lead refining solutions that are tougher, faster, and more adaptable than anything else on the market. A perfect example? Their integration of motor recycling machines equipment into lead refining workflows, allowing clients to process complex scrap that other suppliers can’t handle.

Breaking Barriers with “HybridRefine” Technology

Most lead recyclers focus on single-source waste, like batteries or pure lead scrap. TMS saw an opportunity to tackle mixed waste streams—think old motors, industrial machinery, or even discarded electronics that contain lead components. Their “HybridRefine HX7” system uses a combination of mechanical sorting and chemical leaching to extract lead from these complex materials. For instance, when processing a motor stator (the stationary part of an electric motor), the HX7 first uses a specialized cutter to strip copper windings, then uses a low-temperature smelting process to separate lead from steel casings. The result? A 95% recovery rate from materials that would otherwise end up in landfills. “We don’t let ‘difficult’ waste scare us,” says Hiroshi Tanaka, TMS’s chief technology officer. “Our clients bring us the scrap others reject, and we turn it into profit.”

Durability That Speaks for Itself

TMS machines are built to last. Their “Titanium Series” furnaces use heat-resistant alloys that can withstand 20,000 hours of continuous operation before needing maintenance—double the industry average. This durability has made TMS a favorite among heavy-industry clients, like shipyards and manufacturing plants, which generate large volumes of mixed metal waste. In 2023, Mitsubishi Heavy Industries partnered with TMS to equip its Kobe shipyard with three HybridRefine HX7 systems, processing over 5,000 tons of scrap motors annually. “The reliability is unmatched,” says Keiko Sato, Mitsubishi’s waste management director. “We run 24/7 operations, and the TMS machines have only had two unplanned downtime incidents in two years—that’s unheard of in this industry.”

R&D: The Heart of TMS

With 15% of its annual revenue invested in research and development, TMS isn’t resting on its laurels. The company’s Tokyo lab is currently testing a “NanoClean” filter that uses microscopic ceramic beads to capture lead dust at the molecular level, potentially reducing emissions to near-zero. “The future of recycling isn’t just about processing more waste—it’s about processing it so cleanly that no one notices we’re there,” Tanaka adds. If successful, the NanoClean filter could be integrated into all TMS systems by 2026.

4. Osaka Environmental Technologies (OET)

Osaka Environmental Technologies may not have the decades-long history of some competitors, but since its founding in 2010, this agile firm has made a name for itself by focusing on one thing: accessibility. OET believes that cutting-edge recycling technology shouldn’t be reserved for industry giants, which is why they specialize in compact, affordable lead refining solutions for small to mid-sized businesses. Their claim to fame? Making lead refinery machine equipment that’s as easy to operate as it is effective—no PhD required.

Small But Mighty: The “MicroRefine” Series

OET’s flagship product, the “MicroRefine M5,” is a game-changer for small recyclers. Weighing just 2.5 tons and requiring only a 50 sq.m. footprint, this compact system can process 300 kg of lead scrap per hour—enough to meet the needs of a local recycling cooperative or auto repair shop. What’s remarkable is its simplicity: the M5 uses a touchscreen interface with pre-programmed settings for different scrap types (battery plates, pipes, solder, etc.), so operators with minimal training can get started in hours, not weeks. “We visited over 100 small recyclers before designing the M5,” says Mei Wong, OET’s founder and CEO. “They told us they needed something tough, affordable, and easy to fix. So we built it.”

Affordability Without Compromise

At roughly half the cost of comparable systems, the MicroRefine M5 is a hit with budget-conscious buyers. But OET hasn’t skimped on quality. The M5 uses a patented “QuickClean” furnace lining that can be replaced in under an hour, reducing downtime. It also comes standard with a miniaturized air pollution control system equipment unit, the “CleanAir Mini,” which uses activated carbon and water scrubbing to meet Japan’s strict emission limits. “We refuse to let small operators choose between compliance and profitability,” Wong emphasizes. “The M5 lets them have both.”

Support That Goes Beyond the Sale

OET’s success isn’t just about the machines—it’s about the service. The company offers free on-site training for all clients, along with a 24/7 technical support hotline staffed by bilingual engineers. “When you buy from OET, you’re joining a community,” says Takashi Ito, owner of a small recycling shop in Kyoto that purchased an M5 in 2023. “Last winter, our furnace overheated on a Saturday night. I called OET, and an engineer was at my shop by 9 a.m. Sunday with replacement parts. You don’t get that from the big guys.” OET also offers flexible financing options, including a “pay-as-you-go” plan where clients pay based on the amount of lead processed, making it easier to manage cash flow.

Scaling Up Without Starting Over

As small recyclers grow, OET grows with them. The MicroRefine line is modular, meaning clients can add components—like a larger furnace or automated feeding system—as their needs expand. “One of our first clients started with an M5 in 2015,” Wong recalls. “Today, they’re running three M5s linked together, processing 900 kg/hour. They never had to ｒｅｐｌａｃｅ their original system—they just built around it.” This scalability has made OET a favorite among entrepreneurs looking to test the recycling waters without making a massive upfront investment.

5. Hokkaido Refining Solutions (HRS)

Hokkaido Refining Solutions is proof that innovation can thrive outside Japan’s major tech hubs. Based in Sapporo, this northern firm has carved a niche by designing lead recycling systems that can withstand extreme conditions—like Hokkaido’s freezing winters—while maintaining peak efficiency. But HRS isn’t just about surviving the cold; they’re on a mission to redefine what “sustainable recycling” looks like by creating closed-loop systems that leave zero waste behind. Their expertise in lead acid battery recycling equipment and beyond has made them a go-to for clients in harsh climates worldwide.

Built for the Elements: The “ArcticPro” Line

HRS’s “ArcticPro A7” lead acid battery recycling system is a beast in cold weather. Unlike standard machines that struggle with frozen hydraulic fluids or brittle wiring in sub-zero temperatures, the A7 uses a dual-insulation system and heated components to operate reliably even at -25°C. “We test our systems in Hokkaido’s worst winters because we know our clients in Canada, Scandinavia, and Russia face the same conditions,” says Kenjiro Sato, HRS’s lead engineer. The A7 also features a “ColdStart” mode that preheats critical components in 15 minutes, so operators don’t waste hours waiting for machines to warm up.

Zero-Waste Recycling: The “EcoLoop” Vision

HRS takes the “circular economy” seriously. Their “EcoLoop” system goes beyond lead recovery to extract value from every part of the waste stream. When processing lead acid batteries, for example, the EcoLoop separates plastic casings, which are shredded and sold to plastic recyclers; sulfuric acid, which is converted into battery-grade electrolyte for reuse; and even the paper separators, which are composted into fertilizer. “We don’t see waste—we see resources in the wrong place,” Sato explains. In 2024, HRS partnered with Hokkaido University to develop a process that extracts rare earth metals from lead battery terminals, turning a previously discarded component into a revenue stream for clients.

Community-Driven Sustainability

HRS isn’t just a supplier—they’re active members of the communities they serve. The company runs a “Recycling Education Program” in Hokkaido schools, teaching kids about the importance of resource recovery. They also offer grants to small local recyclers to upgrade to EcoLoop systems, helping rural areas reduce reliance on landfills. “Sustainability starts at home,” says Yuki Aoki, HRS’s community outreach director. “If we can make recycling profitable and accessible in Hokkaido, we can do it anywhere.”

Looking North, Thinking Global

While HRS is proud of its Hokkaido roots, its sights are set on global expansion. The company recently signed a deal to supply ArcticPro systems to a mining operation in northern Sweden, where extreme cold has long made on-site lead recycling impossible. “Our machines don’t just process lead—they open up new possibilities for recycling in places no one thought possible,” Sato adds. With plans to open a European office in 2025, HRS is poised to become a major player in the global lead recycling market.
