Top 7 Paste Reduction Melting Furnace Suppliers in the United States

When it comes to balancing power and precision, EcoCycle Technologies has been a household name in American recycling since 2001. Based in Chicago, this family-owned business started with a simple goal: make lead-acid battery recycling safer and more efficient for small to mid-sized plants. Fast forward two decades, and their rotary furnace for paste reduction has become a gold standard in the industry.

What makes EcoCycle’s furnaces stand out? For starters, they’re designed to work seamlessly with their own lead acid battery breaking and separation system , creating a closed-loop process that minimizes human contact with hazardous materials. The furnace itself uses a unique tilting mechanism that ensures even heat distribution, reducing paste-to-lead conversion time by up to 15% compared to traditional models. But what really wins over customers is the attention to环保 compliance. Each unit comes with an integrated air pollution control system —think high-efficiency particulate filters and sulfur dioxide scrubbers—that meets even the strictest EPA standards.

“We switched to EcoCycle three years ago, and the difference in our daily operations is night and day,” says Maria Gonzalez, operations manager at GreenState Recycling in Ohio. “Our energy bills are down, our emissions are way below the limit, and the support team is always just a phone call away. They don’t just sell you a furnace—they partner with you to make your whole plant run better.”

Headquartered in Houston, American MetalMelt Systems (AMS) has built its reputation on one thing: power. Founded in 1995, this industry giant specializes in furnaces for large-scale operations, and their medium frequency electricity furnace for paste reduction is a beast in the best way possible. Capable of processing up to 5 tons of battery paste per hour, these furnaces are the workhorses behind some of the biggest recycling plants in the country.

But AMS doesn’t just focus on size—they’re also pioneers in automation. Their latest model, the MegaMelt 8000, comes with a fully integrated touchscreen control system that lets operators monitor temperature, pressure, and emissions in real time. It even sends alerts to your phone if something’s off, so you can address issues before they become costly downtime. And for plants looking to go all-in on lead recycling, AMS offers a complete package: furnace, lead refinery machine , and filter press to collect the paste —all from one supplier, all designed to work together.

“We process over 200 tons of batteries a week, so we needed something that could keep up,” explains James Wilson, plant director at Gulf Coast Recyclers in Texas. “The MegaMelt doesn’t just keep up—it thrives. We’ve had it running for two years straight with barely any maintenance issues. Plus, the refinery machine that comes with it produces lead purity levels we never thought possible with recycled material. Our customers in the automotive industry love it.”

For plants that prioritize sustainability without sacrificing performance, GreenForge Innovations is the name to know. Founded in Portland in 2010 by a team of environmental engineers, this supplier has made a name for itself with its dry process paste reduction furnace—a technology that uses 30% less water than traditional wet-process models. That’s a big deal for facilities in water-scarce regions or those looking to cut down on wastewater treatment costs.

GreenForge’s furnace uses a proprietary heating element that recycles excess heat back into the system, slashing energy consumption by up to 25%. It also pairs perfectly with their plastic pneumatic conveying system , which automatically moves plastic casing waste away from the furnace area, keeping the workspace clean and reducing fire risks. But what truly sets them apart is their commitment to small businesses. They offer flexible financing options and even rent-to-own plans, making advanced recycling tech accessible to startups that might otherwise be priced out.

“As a new plant, we couldn’t afford the big-name furnaces upfront,” says Raj Patel, owner of EverGreen Recycling in Colorado. “GreenForge worked with us to create a payment plan that fit our budget, and their furnace has been running like a dream for 18 months. We’re saving so much on water and electricity that we’ll have paid it off in no time. Plus, knowing we’re using a dry process that’s gentler on the planet? That’s the cherry on top.”

Liberty Recycling Equipment Co. has been a staple in the American Midwest since the 1980s, and their longevity speaks volumes. Based in Cleveland, this supplier is known for two things: rugged durability and old-school customer service. Their blast (cupola) furnace for lead battery recycling is a throwback in the best sense—built with thick, heat-resistant steel and simple, easy-to-repair components that mean less downtime when things go wrong.

Don’t let the traditional design fool you, though—Liberty has kept up with the times. Their latest furnace model includes a digital temperature control system and a de-sulfurization unit that reduces harmful sulfur emissions by over 90%. They also offer a wide range of auxiliary equipment , from conveyors to cooling racks, so you can customize your setup to fit your space. And if you ever run into issues? Their tech support team is based in the U.S., with average response times under 30 minutes.

“We’ve had our Liberty furnace since the ’90s, and it’s still going strong,” laughs Tom Reynolds, who runs Reynolds Recycling in Michigan with his son. “We upgraded the control system a few years ago, and it’s like having a new machine. What I love most is that when we call for parts, they’re here the next day—no waiting for shipments from overseas. In this business, time is money, and Liberty gets that.”

On the West Coast, Pacific Rim Recycling Tech (PRRT) is making waves with its focus on innovation and global collaboration. Founded in Seattle in 2008, this supplier partners with engineering firms in Japan and Germany to bring cutting-edge furnace technology to the U.S. market. Their star product? A nano ceramic ball -enhanced paste reduction furnace that uses specially designed ceramic balls in the heating chamber to improve heat transfer and reduce wear and tear on the furnace lining.

The result? A furnace that lasts up to 50% longer than standard models and requires 40% less maintenance. PRRT also offers a unique air pollution control system for li battery recycling plant , making them a one-stop shop for facilities that handle both lead-acid and lithium-ion batteries. And for plants near the coast, they’ve developed a corrosion-resistant model that stands up to salt air—a small detail that makes a big difference for operations in states like California and Florida.

“We handle both lead and lithium batteries, so having a supplier that can support both is a game-changer,” says Sarah Chen, sustainability director at West Coast E-Waste in Oregon. “The nano ceramic balls in the furnace are incredible—we used to have to ｒｅｐｌａｃｅ the lining every year, and now it’s been three years and it still looks new. PRRT’s team even sent engineers to our plant to help us integrate the lithium recycling system with the existing lead setup. That level of support is hard to find.”

For facilities that need a furnace that can do it all, Heartland Recycling Machinery delivers. Based in Indianapolis, this supplier has built its brand on versatility, and their flagship paste reduction furnace is no exception. It’s designed to handle not just lead-acid battery paste, but also other materials like circuit board recycling residues and scrap cable insulation—making it ideal for multi-material recycling plants.

Heartland’s furnace comes with a modular design, so you can add components as your business grows. Start with the basic paste reduction unit, then later add a hydraulic briquetter to compress lead ingots for easier transport, or a wet process attachment for handling more complex materials. They also offer on-site training for your staff, ensuring everyone knows how to operate the furnace safely and efficiently from day one.

“We started with just lead batteries, but as our business grew, we wanted to branch out into circuit boards,” says Mike Johnson, owner of Crossroads Recycling in Indiana. “Instead of buying a whole new furnace, we just added the circuit board module to our Heartland unit. It was seamless—took their tech team two days to install, and we were up and running. Now we’re recycling twice as much material with the same footprint. That’s the kind of flexibility small businesses need.”

Rounding out our list is New England Metal Recovery (NEMR), a supplier that proves bigger isn’t always better. Based in Boston, this small but mighty company has been serving the Northeast since 2015, specializing in compact, energy-efficient furnaces perfect for urban recycling facilities where space is at a premium.

NEMR’s furnace is 40% smaller than most competitors’ models but doesn’t skimp on power—it can still process up to 1 ton of paste per hour. It also features a portable design with locking casters, so you can move it around your facility as needed. And for plants in cold climates, they’ve added an insulated outer casing that reduces heat loss in winter, keeping energy costs low even when temperatures ｄｒｏｐ below freezing.

“Our plant is in downtown Boston, so space is super tight,” explains Lisa Wong, operations manager at Urban Recycling Co. “NEMR’s furnace fits perfectly in our corner, and being able to move it when we need to clean or rearrange is a lifesaver. We were worried a smaller furnace might not keep up with demand, but it’s been chugging along flawlessly. Plus, their team is local—if we have a problem, they’re here within hours, not days. For urban recyclers, that kind of proximity is priceless.”
