India’s recycling sector is growing fast, and Mumbai Metal Works (MMW) is right there with it, specializing in affordable, rugged furnaces tailored to local needs. MMW’s blast (cupola) furnace for lead battery recycling plant models, like the MB-2000, are built to handle India’s power fluctuations and dusty conditions—common challenges in smaller recycling yards. “Many Indian recyclers operate in rural areas with unstable electricity,” says MMW founder Raj Patel. “Our furnaces have backup generators and dust filters to keep running no matter what.”

Founded in 2008, MMW started by repairing old furnaces and now manufactures its own line, with prices 30% lower than imported options. Their bestseller, the MB-1500, is a compact furnace ideal for small to mid-sized plants, with a capacity of 1.5 tons/hour. “We don’t try to compete with the big Chinese suppliers on size,” Patel explains. “Instead, we focus on affordability and local service. If a customer in Chennai needs a part, we can deliver it in 24 hours—not two weeks.”

MMW also offers training programs for operators, ensuring recyclers get the most out of their equipment. “A furnace is only as good as the person running it,” Patel adds. “We teach them how to optimize temperature, clean filters, and troubleshoot common issues.”

5. Singapore GreenTech Solutions (Singapore)

Singapore might be small, but GreenTech Solutions punches above its weight with eco-friendly furnace tech. Their “CleanBurn” series of paste reduction furnaces is designed to minimize emissions, a big selling point for recyclers in countries with strict环保 laws (like Japan and South Korea). GreenTech’s furnaces capture over 95% of sulfur dioxide, which can then be converted into sulfuric acid for reuse—turning a waste product into a revenue stream.

Founded in 2010, GreenTech partners with universities to stay ahead on sustainability. Their 2025 model, the CleanBurn Pro, uses a two-stage combustion process to reduce nitrogen oxide emissions by 40%. “We see the writing on the wall,” says GreenTech CEO Lisa Wong. “Governments are cracking down on pollution, and recyclers need furnaces that meet those new standards without sacrificing efficiency.”

While GreenTech’s furnaces are pricier, they appeal to companies looking to brand themselves as eco-conscious. “A European recycler told us our furnace helped them get a ‘green certification,’ which opened doors to government contracts,” Wong notes. With a focus on R&D, GreenTech spends 15% of its revenue on developing new emission-control tech—money that seems to be paying off, with sales up 35% in 2024.

6. Seoul Machinery Co. (South Korea)

Not to be confused with Seoul Recycling Innovations, Seoul Machinery Co., or SMC, is a legacy player with over 50 years in the game. Founded in 1973, SMC started making industrial furnaces and pivoted to battery recycling equipment in the 2000s. Today, their furnace for paste reduction melting equipment is a favorite among mid-sized recyclers, thanks to its balance of price, performance, and ease of use.

SMC’s most popular model, the PM-2000, is a workhorse that can handle 2 tons/hour with minimal operator training. “We design for simplicity,” says SMC’s product manager, Park Soo-jin. “A recycler shouldn’t need a PhD to run a furnace. Our control panel has big, clear buttons and a touchscreen with step-by-step guides.” SMC also offers flexible financing, letting customers pay in installments—helpful for small businesses just starting out.

With a factory in Busan, SMC exports to 25+ countries, with strong sales in Indonesia and the Philippines. “We’re not the flashiest, but we’re reliable,” Park adds. “Our furnaces might not have all the bells and whistles, but they get the job done—and that’s what matters.”

7. Beijing LeadTech (China)

Beijing LeadTech is all about innovation, and their 2025 “UltraHeat” furnace lineup proves it. These furnaces use induction heating instead of traditional burners, which heats the lead paste more evenly and reduces processing time by 15%. Induction tech also allows for precise temperature control—critical for getting high-purity lead. “Traditional furnaces heat from the outside in, leading to hot spots,” explains LeadTech engineer Zhang Wei. “Induction heats the paste itself, so every particle gets the same treatment.”

Founded in 2001, LeadTech has grown into a major player in China’s recycling equipment market, with a focus on R&D. They even operate their own test recycling plant, where they put new furnace models through months of rigorous trials before releasing them. “We don’t just design on paper,” Zhang says. “We build it, test it, break it, and fix it—so our customers don’t have to.”

LeadTech’s UltraHeat 2500 is popular in India and Bangladesh, where recyclers want faster processing times. The furnace can go from cold start to operating temperature in under an hour, compared to 2–3 hours for conventional models. “Time is money,” Zhang adds. “A furnace that heats up quickly means recyclers can start production faster each day.”

8. Osaka Recycling Equipment (Japan)

Osaka Recycling Equipment, or ORE, is a niche supplier with a loyal following—especially among recyclers who need custom solutions. Unlike larger companies that offer “one-size-fits-all” furnaces, ORE will design a rotary furnace for paste reduction tailored to a customer’s specific needs. “A recycler in Vietnam might have space constraints, while one in Australia needs to handle different battery types,” says ORE’s design lead, Hiroshi Mori. “We listen to their challenges and build a furnace that fits.”

Founded in 1985, ORE is a family-owned business that prides itself on craftsmanship. Each furnace is assembled by hand by a team of skilled technicians, and ORE offers a 10-year warranty on parts—unheard of in the industry. “We take pride in our work,” Mori says. “When you buy an ORE furnace, you’re getting something built to last.”

While ORE’s custom approach means higher prices and longer lead times (3–6 months per furnace), their customers say it’s worth it. “We needed a furnace that could fit in our small Jakarta plant,” says a customer, Rudi Setiawan. “ORE designed one with a smaller footprint but kept the same capacity. Now we’re recycling 1.2 tons/hour without expanding our building.”

9. Bangkok Metal Tech (Thailand)

Bangkok Metal Tech, or BMT, is Southeast Asia’s rising star, with a focus on making recycling equipment accessible to small and medium enterprises (SMEs). Their “MiniMaster” series of paste reduction furnaces is designed for recyclers with limited space and budget—think capacity options from 500kg/h to 1.5t/h and prices starting at $50,000. “In Thailand, most recyclers are SMEs,” says BMT’s founder, Somchai Wong. “They can’t afford a $200,000 furnace, so we built one that’s affordable but still reliable.”

Founded in 2015, BMT started with a single workshop and now has a factory outside Bangkok, supplying to Cambodia, Laos, and Myanmar. Their furnaces are simple but effective, with basic controls and easy-to-find replacement parts. BMT also offers rent-to-own plans, letting recyclers pay monthly while using the furnace. “We want to help small businesses grow,” Wong adds. “A lot of our customers start with a MiniMaster 500 and upgrade to a 1.5t/h model as their business expands—and we’re there to support them every step.”

BMT’s secret weapon? Local partnerships. They team up with battery retailers to refer customers, creating a win-win: retailers get rid of old batteries, and recyclers get a steady supply. “It’s all about building a ecosystem,” Wong notes. “We don’t just sell furnaces—we help build businesses.”

10. Taipei Furnace Works (Taiwan)

Rounding out our list is Taipei Furnace Works, or TFW, a Taiwanese supplier known for its durable, low-maintenance furnaces. TFW’s “Endurance” series is built to handle the wear and tear of continuous operation, with replaceable parts that are easy to swap out. “Our furnaces are like pickup trucks—tough, simple, and built to last,” says TFW’s sales manager, Kevin Chen. “We use high-grade steel for the外壳 (shell) and heat-resistant alloys for the inner liners, so they can take a beating.”

Founded in 1998, TFW has a strong presence in East Asia, with customers in China, Japan, and South Korea. Their most popular model, the Endurance 2000, can run for up to 10,000 hours before needing major maintenance—double the industry average. “Recyclers don’t want to stop production for repairs,” Chen explains. “So we design our furnaces to be easy to service. A technician can ｒｅｐｌａｃｅ a heating element in under an hour, without special tools.”

TFW also offers training workshops in Taipei, where customers can learn maintenance tips and tricks. “Knowledge is power,” Chen adds. “If a recycler knows how to fix small issues themselves, they save time and money. That’s why we host these workshops—we want our customers to be self-sufficient.”
