When it comes to recycling, especially for lead-acid batteries, one piece of equipment stands out as a true workhorse: the paste reduction melting furnace. These machines are the backbone of turning old, discarded batteries into reusable lead, helping industries cut down on raw material costs and reduce environmental impact. China, being a global leader in manufacturing and recycling technology, is home to some of the most innovative suppliers of these furnaces. In 2025, as the world pushes harder for sustainability, these suppliers are stepping up with smarter, greener, and more efficient solutions. Let’s take a closer look at the top 10 names you need to know in this space.
Before we dive into the suppliers, let’s quickly break down why these furnaces are so crucial. Lead-acid batteries are everywhere—cars, motorcycles, backup power systems—and when they reach the end of their life, they’re packed with valuable lead paste. But extracting that lead safely and efficiently? That’s where paste reduction melting furnaces come in. They heat the paste at precise temperatures, separating lead from other materials while minimizing harmful emissions. With stricter环保 regulations (environmental regulations) worldwide, modern furnaces also come with advanced air pollution control systems to keep operations clean. Now, let’s meet the companies making this possible.
Beijing LeadCycle Tech Co., Ltd.
Another big plus? They don’t stop at the furnace itself. LeadCycle Tech pairs their melting equipment with a full lead acid battery breaking and separation system, creating a one-stop solution for recycling plants. This integration means less hassle for customers—no need to piece together equipment from different suppliers. Their systems are already in use across 12 countries , from Southeast Asia to Europe, and they’ve just announced a new partnership with a major recycling firm in Brazil.
Shanghai EcoSmelt Machinery
But what really sets them apart is their smart control system. Operators can monitor and adjust furnace temperature, rotation speed, and gas flow in real time via a touchscreen panel or even a mobile app. “We wanted to make these furnaces easier to use, even for workers who aren’t tech experts,” says Li Wei, their head of R&D. And it’s paying off: EcoSmelt’s furnaces now hold a 15% market share in China’s lead recycling equipment sector.
They also offer tailored solutions. For small to mid-sized plants, their compact ECO-Melt 1500 is a hit, while larger facilities opt for the high-capacity ECO-Melt 5000, which can process up to 5 tons of lead paste per day . Plus, their after-sales service is top-notch—they have a team of engineers on call 24/7 for troubleshooting, which customers love.
Guangzhou MetalRecycle Equipment Co.
One of their key strengths is energy efficiency. The MR-Fusion furnaces use a double-layer insulation design that reduces heat loss by 30% , lowering electricity bills for plant operators. They also offer a range of auxiliary equipment, like filter press machines to collect lead paste and air pollution control systems, making them a one-stop shop for recycling plants that want to keep things simple.
While they’re based in Guangzhou, their reach is global. They’ve supplied furnaces to major recycling projects in India, Nigeria, and Australia, and in 2024, they opened a new office in Dubai to better serve the Middle East market. “Our goal is to make reliable equipment accessible everywhere,” says Zhang Mei, their export manager. “You don’t have to compromise on quality just because you’re in a smaller market.”
Shenzhen GreenTech Furnaces
Another standout feature? Their low-emission burner system. GreenTech worked with researchers from Tsinghua University to develop a burner that uses 95% less natural gas than standard models, without sacrificing heating power. “Sustainability isn’t just about reducing emissions—it’s also about saving energy,” explains Chen Hao, their founder. This innovation has earned them grants from the Chinese government’s green technology fund.
While they’re best known for their paste reduction furnaces, GreenTech also dabbles in lithium battery recycling equipment—though they’re quick to note that lead-acid recycling remains their core. “We want to master one area before branching out too much,” Chen adds. So far, their strategy is working: they’ve doubled their revenue every year since 2019, and 2025 looks set to be another record-breaker.
Hangzhou FurnaceMaster Industries
Their standard line, the FM-Pro Series, isn’t too shabby either. The FM-Pro 4000 comes with a dual-chamber design : the first chamber preheats the paste, and the second handles the actual reduction, which boosts efficiency by 18% . They also offer training for operators, sending technicians to customer sites to run workshops on furnace maintenance and safety—something many competitors skip.
FurnaceMaster has a strong presence in China’s domestic market, with over 200 installations across provinces like Jiangsu, Shandong, and Henan. But they’re also eyeing international growth—they recently signed a deal to supply 10 furnaces to a recycling plant in Kenya, their first foray into Africa. “We believe our focus on customization will help us stand out overseas,” says Wang Jun, their sales director.
Wuhan LeadWorks Machinery
But size doesn’t mean sacrificing control. The MegaMelt comes with a computerized monitoring system that tracks every step of the process, from paste input to lead output, and even sends alerts if something’s off. “We’ve had customers tell us the system has saved them from costly mistakes, like overheating batches,” says Liu Yang, their technical support lead. They also offer a 5-year warranty on their MegaMelt furnaces—one of the longest in the industry.
LeadWorks works closely with battery manufacturers, too. They recently partnered with a major Chinese car battery brand to design a furnace that pairs seamlessly with the brand’s battery dismantling lines, creating a closed-loop recycling system. “It’s all about making recycling as efficient as possible for our clients,” Liu adds.
Chengdu EcoFurnace Solutions
Their EF-Clean 2500 is a favorite among mid-sized plants. It’s compact, easy to install, and uses variable speed rotation —slowing down for thick paste, speeding up for thinner batches—to ensure consistent results. They also offer a “green package” that includes solar panels to power the furnace, appealing to plants aiming for carbon neutrality.
EcoFurnace is part of a larger group that also makes solar inverters and wind turbine parts, so they have plenty of expertise in renewable energy integration. “We want to be more than just a furnace supplier—we want to help our customers build fully sustainable recycling operations,” Zhao explains. It’s a vision that’s resonating: their sales in Europe grew by 40% in 2024.
Nanjing MetalFlow Equipment
Their paste reduction furnace, the MF-Fusion 3500, is the heart of these lines. It’s designed to work seamlessly with their lead acid battery breaking and separation system, so paste moves from breaking to melting without manual handling—reducing labor costs and safety risks. The furnace also has a self-cleaning feature : after each batch, a small scraper removes leftover residue from the drum, cutting down on maintenance time.
One of their success stories? A recycling plant in Vietnam that went from 0 to 500 batteries processed per day in just 3 months using MetalFlow’s turnkey line. “We handled everything from installation to training, so they could focus on running the business,” says Pham Thi, their international project manager. MetalFlow now has turnkey projects in over 15 countries , with plans to expand into South America next year.
Qingdao FurnaceTech Innovations
But AI isn’t their only trick. The FT-X also has a 360-degree camera system inside the furnace, giving operators a real-time view of the paste as it melts. “It’s like having X-ray vision into the process,” jokes Zhang Wei, their AI research lead. This helps catch issues early, like uneven melting or blockages, before they become big problems.
FurnaceTech is a relative startup, founded in 2017, but they’ve attracted big-name investors, including a venture capital firm backed by Alibaba Group. “We’re not afraid to take risks with new technology,” Zhang adds. “The recycling industry is evolving fast, and we want to evolve with it.” Their focus on innovation has made them a favorite among tech-savvy plant owners, especially in China’s coastal tech hubs like Shenzhen and Hangzhou.
Dongguan LeadMaster Equipment
Don’t let the lower price fool you, though—their LM-Basic Series is packed with features. The LM-Basic 2000 has a ceramic fiber insulation (lighter and more heat-resistant than traditional brick) and a user-friendly control panel with simple buttons and dials. “We wanted to make high-quality furnaces accessible to smaller players,” says Huang Li, their founder. “Not every plant can afford a million-dollar machine, but they still need reliable equipment.”
LeadMaster also offers flexible payment plans, letting customers pay in installments over 2 years. And their after-sales support is surprisingly robust for a budget brand—they have a toll-free hotline and an online library of troubleshooting videos. It’s a strategy that’s working: they now have over 300 small-scale customers across China, and they’re starting to export to Southeast Asia, where small recycling plants are booming.
