Top 10 Paste Reduction Smelting Furnace Suppliers in the United States

Founded in 2005, EcoCycle Solutions has built a reputation as the "innovation hub" of recycling equipment. Their star product? The rotary furnace for paste reduction —a machine that’s become a game-changer for mid-sized to large recycling plants. What sets it apart? A dual-chamber design that first dries the lead paste and then reduces it, cutting processing time by 20% compared to single-chamber models.

But EcoCycle doesn’t stop at furnaces. They’re all about full-system solutions, which is why they pair their rotary furnaces with in-house designed lead acid battery breaking and separating equipment . This combo ensures that from battery crushing to lead recovery, every step works in sync. One customer in Michigan raved, "We used to have bottlenecks between breaking and smelting—now it’s a smooth flow. Our lead output jumped 25% in the first month."

Sustainability is another win here. Their furnaces come with built-in de-sulfurization machines that capture sulfur dioxide emissions, making them compliant with even the strictest EPA standards. If you’re looking for a one-stop shop that values both performance and planet, EcoCycle is a top contender.

When it comes to high-capacity smelting, AmeriRecycle Technologies is the name that comes up again and again. Based in Atlanta, this company has been dominating the industrial recycling scene since 2010, with a focus on furnaces that can handle the heavy lifting. Their flagship model, the AR-2000, boasts a jaw-dropping capacity of 2000 kg/hour—perfect for mega-plants processing tens of thousands of batteries weekly.

What makes the AR-2000 a beast? It’s all in the heating system. AmeriRecycle uses medium-frequency induction technology, which heats the lead paste more evenly than traditional flame-based furnaces. This not only reduces energy costs by 18% but also produces purer lead (99.97% purity, to be exact). "We used to spend hours refining lead after smelting," said a plant manager in Texas. "With AmeriRecycle’s furnace, the lead is almost ready to sell right out of the tap."

Customer support is another area where they shine. They offer 24/7 technical assistance and even send engineers for on-site training during installation. One downside? Their equipment is built for scale, so smaller plants might find the price tag steep. But if you need to process large volumes without sacrificing quality, AmeriRecycle delivers.

For eco-conscious recyclers, GreenState Furnace Works is a breath of fresh air. This Portland-based company has made "green tech" their mission since 2012, and their paste reduction furnaces are a testament to that. Take their EcoMelt Pro: it’s the first smelting furnace in the U.S. to earn a CarbonNeutral® certification, thanks to its solar-ready design and low-emission burner system.

But don’t let the "green" label fool you—this furnace is no slouch in performance. It handles 800-1500 kg/hour of lead paste and features an automatic feed system that adjusts paste input based on furnace temperature, preventing overloading. "We used to have operators constantly monitoring the feed—now the machine does it itself," said a sustainability director in Oregon. "It’s cut labor costs and reduced human error."

GreenState also offers a unique "Lease-to-Own" program, making their tech accessible to smaller plants that might not have the capital for upfront purchases. If sustainability and flexibility are your priorities, this is the supplier to watch.

National Recovery Systems (NRS) has been a staple in the Chicago manufacturing scene since 1998, and their paste reduction furnaces are known for one thing: durability. These machines are built like tanks—many customers report using NRS furnaces for 15+ years with minimal major repairs. Their secret? Heavy-duty steel construction and components sourced from U.S.-based suppliers, ensuring quality control from start to finish.

Their most popular model, the NRS-1200, is a workhorse for mid-sized plants, handling 1200 kg/hour with a focus on simplicity. No fancy touchscreens here—just intuitive controls that even new operators can master in a day. "We have a high turnover of staff, so ease of use is crucial," said a plant owner in Indiana. "NRS’s furnace is so straightforward, we can train someone in the morning and have them running it by afternoon."

NRS also offers unbeatable after-sales service. Their tech support team is based in Chicago, so you won’t be waiting on hold for an overseas rep. They even stock replacement parts locally, meaning most repairs can be done within 48 hours. For reliability and peace of mind, NRS is hard to beat.

ProSmelt Industries is the new kid on the block, founded in 2018, but they’ve quickly made a name for themselves with cutting-edge automation. Their SmartMelt series isn’t just a furnace—it’s a connected system. Equipped with IoT sensors, it sends real-time data to your phone or laptop, alerting you to temperature fluctuations, maintenance needs, or feed issues before they become problems. "I can check furnace performance from my couch on a Sunday," laughed a plant manager in Louisiana. "It’s like having a 24/7 watchdog for my smelting line."

Performance-wise, the SmartMelt 1500 holds its own, processing 1500 kg/hour with a focus on energy efficiency. It uses a heat recovery system that captures waste heat from the exhaust and redirects it to preheat incoming lead paste, slashing energy use by 22%. Plus, its compact design takes up 30% less floor space than comparable furnaces—a big win for plants tight on room.

ProSmelt’s weakness? They’re still building their customer base, so there are fewer long-term reviews. But if you’re tech-savvy and want the latest in smart manufacturing, this up-and-comer is worth a look.

EverGreen Recycling Equipment is all about customization. Based in Seattle, they specialize in building paste reduction furnaces tailored to your specific needs—whether you’re a small startup processing 300 kg/hour or a giant plant needing 2500 kg/hour. Their team of engineers works with you to design a furnace that fits your space, budget, and production goals, which is why they’re a favorite among niche recyclers.

One example: a customer in Alaska needed a furnace that could operate in sub-zero temperatures (their plant isn’t heated year-round). EverGreen modified their standard model with insulated panels and a pre-heating jacket, ensuring it runs smoothly even when it’s -20°F outside. "They didn’t just sell us a furnace—they solved a problem we thought was unsolvable," the customer said.

EverGreen also prides itself on transparency. They provide detailed energy and emission reports for each custom build, so you know exactly how your furnace stacks up against industry standards. If off-the-shelf models just don’t fit your needs, EverGreen’s custom approach is a game-changer.

Pittsburgh’s IronClad Furnaces has been around since 1985, and they’ve earned their reputation as the "old reliable" of the industry. Their paste reduction furnaces are known for consistency—batch after batch, they deliver the same high-quality lead, which is why automotive manufacturers (who demand strict purity standards) love them. Their IC-1000 model, a staple for over 20 years, processes 1000 kg/hour and has a track record of 99.9% uptime.

What’s their secret to consistency? A proprietary refractory lining that resists wear and tear, even with daily use. Most furnaces need lining replacements every 6-8 months; IronClad’s last 12-14 months, saving you downtime and maintenance costs. "We used to schedule lining repairs every quarter—it was a headache," said a plant manager in Detroit. "With IronClad, we only do it once a year, and it’s smooth sailing."

IronClad isn’t big on flashy features, but they excel at the basics. Their furnaces are easy to maintain, parts are affordable, and their team has decades of experience troubleshooting. If you value tried-and-true reliability over cutting-edge bells and whistles, IronClad is a solid choice.

CleanTech Smelting is on a mission to make lead recycling cleaner than ever. Their Denver-based team has developed a paste reduction furnace with a closed-loop emissions system that captures over 99% of harmful particulates and gases. It’s so effective that some plants have used it to qualify for green energy tax credits. "We were skeptical at first, but the emissions data speaks for itself," said an environmental compliance officer in Colorado. "Our last EPA audit was a breeze—they couldn’t find a single超标 reading."

Performance isn’t compromised for the sake of green tech, either. Their CleanMelt 1800 processes 1800 kg/hour and uses a unique airtight feeding system that prevents lead dust from escaping into the plant. This not only keeps workers healthier but also reduces lead waste—meaning more product to sell. "We used to lose 5-7% of lead to dust; now it’s less than 2%," a production supervisor noted.

CleanTech’s only downside is price—their closed-loop system adds about 15% to the upfront cost. But for plants in states with strict environmental laws (looking at you, California and New York), the investment pays off in compliance and peace of mind.

MidWest Recycling Systems is all about value. They offer some of the most affordable paste reduction furnaces on the market, without skimping on quality. Their entry-level model, the MWR-800, starts at $75,000—about 30% less than comparable furnaces from top brands. This makes them a go-to for startups or small plants just getting off the ground.

Don’t let the low price fool you—the MWR-800 is no toy. It processes 800 kg/hour, has a user-friendly control panel, and comes with a 2-year warranty (unheard of for budget models). "We started with a shoestring budget and couldn’t afford the big names," said a new recycler in Iowa. "MidWest’s furnace got us up and running, and it’s performed like a champ for two years now."

MidWest does cut costs in a few areas—they use imported components (though still high-quality) and offer limited customization. But if you need reliable equipment on a tight budget, they’re hard to beat.

Rounding out our list is PacificCoast Recycling Tech, a California-based supplier known for speed. Their SpeedMelt 2000 furnace lives up to its name, processing 2000 kg/hour with a cycle time of just 45 minutes per batch—15 minutes faster than the industry average. How do they do it? A high-powered burner and optimized airflow design that ensures rapid heating and reduction.

This speed is a lifesaver for plants with tight deadlines. One customer in California, who handles rush orders for auto parts manufacturers, said, "When a client needs lead fast, PacificCoast’s furnace delivers. We’ve been able to take on bigger orders because we know we can meet the turnaround."

SpeedMelt does require more frequent maintenance (every 3 months instead of 6), but PacificCoast offers a flat-rate maintenance plan to keep costs predictable. If speed is your top priority, this is the furnace for you.
