Top Canadian Manufacturers: Explore the 20 Best Paste Reduction Melting Furnace Suppliers

Based in Toronto, Northern Recycling Technologies (NRT) has been a cornerstone of Canada’s recycling equipment scene since 1998. What sets them apart? Their holistic approach to lead acid battery recycling. Instead of selling standalone furnaces, NRT designs complete systems that start with battery breaking and end with pure lead ingots. Their flagship offering? A lead acid battery breaking and separation system that efficiently splits batteries into plastic, acid, and lead components, feeding directly into their rotary furnace for paste reduction . The furnace itself is a marvel of engineering: equipped with advanced temperature control (±2°C accuracy) and a proprietary combustion system that reduces energy use by 15% compared to industry standards. But NRT doesn’t stop at efficiency—their air pollution control system includes multi-stage filters and scrubbers that capture over 99.9% of emissions, meeting Canada’s strict CEPA (Canadian Environmental Protection Act) standards. “We worked with NRT to upgrade our facility in 2022,” says Maria Gonzalez, operations manager at GreenCycle EU. “Their furnace cut our lead recovery time by 20%, and the pollution control system was so effective, we passed our EU ETS audits with zero issues.”

NRT’s client base spans small local recyclers to multinational corporations, with customizable systems for capacities ranging from 500 kg/hour to 5,000 kg/hour. They also offer 24/7 technical support, a rarity in the industry, and provide on-site training for operators. If you’re looking for a “one-stop shop” for lead acid battery recycling, NRT is a top contender.

Headquartered in Vancouver, EFS has carved a niche in serving mid-sized recycling operations that need high performance without the price tag of industrial-scale equipment. Founded by a team of metallurgical engineers, EFS focuses on rotary furnace for paste reduction units that are compact, energy-efficient, and surprisingly powerful. Their most popular model, the EFS-RF500, handles 500-800 kg/hour of lead paste and fits in spaces as small as 300 sq. ft.—perfect for urban recycling centers or facilities with limited square footage. What really makes EFS stand out, though, is their commitment to portability. For remote locations or temporary projects, they offer a trailer-mounted version of the RF500, complete with a built-in air pollution control system (think: mini scrubbers and HEPA filters) that can be transported via truck. “We operate a recycling plant in northern Alberta, where logistics are tough,” explains James Wilson, owner of Northern Lead Recovery. “EFS’s portable furnace arrived on a flatbed, was set up in two days, and has run non-stop for 18 months. No other supplier could meet our mobility needs without sacrificing quality.”

EFS also prides itself on transparency. They provide detailed energy consumption reports, emission testing data, and even invite potential clients to tour their manufacturing facility in Vancouver to see the furnaces being built. Their filter press equipment , designed to separate solid residues from acid during the recycling process, is another highlight—made with corrosion-resistant materials that extend lifespan by 3-5 years compared to generic filters.

MLM, based in Hamilton, Ontario, is a name synonymous with heavy-duty industrial equipment. Founded in 1975, they’ve weathered economic ups and downs by focusing on durability—and their rotary furnace for paste reduction units are built to last. The MLM-2000, their flagship model, is designed for high-volume operations (2,000+ kg/hour) and features a 10mm-thick steel drum lined with heat-resistant ceramic tiles that can withstand temperatures up to 1,200°C. “We’ve had our MLM furnace since 2015, and we’ve only replaced the drum lining once,” says Raj Patel, plant manager at MegaCycle USA. “In that time, we’ve processed over 10,000 tons of lead paste—unheard of with our previous equipment.” But MLM isn’t stuck in the past. In 2020, they launched their “Smart Furnace” line, which uses IoT sensors to monitor temperature, pressure, and emissions in real time, sending alerts to operators’ phones if parameters drift. This has reduced downtime by 30% for clients like Patel’s plant.

MLM also offers a lead acid battery breaking and separation system that integrates with their furnaces, featuring hydraulic cutters and magnetic separators to maximize material recovery. Their air pollution control system is modular, allowing clients to add components (like activated carbon filters) as regulations tighten. While MLM’s equipment comes with a higher upfront cost, their 10-year warranty and 98% uptime rate make it a smart long-term investment for large-scale recyclers.

Montreal-based GTR is all about sustainability—even in their own manufacturing process. They were the first Canadian recycling equipment supplier to achieve net-zero carbon emissions in their factory, and that eco-consciousness trickles down to their products. Their rotary furnace for paste reduction uses a hybrid heating system that combines natural gas with waste heat recovery, cutting fuel costs by 25%. But the real star is their filter press equipment , which uses a closed-loop water system to minimize waste. “Traditional filter presses can use up to 500 liters of water per hour,” explains GTR’s lead engineer, Sophie Dubois. “Ours recycles 95% of that water, making it ideal for regions with water scarcity.” GTR also offers a unique “carbon-neutral furnace” package: for every unit sold, they plant 500 trees through partnerships with Canadian reforestation NGOs, a hit with clients marketing their sustainability credentials.

GTR’s systems are popular in Europe and Asia, where strict carbon footprint regulations are driving demand for green equipment. Their air pollution control system includes a catalytic converter that reduces NOx emissions by 80%, and their lead acid battery breaking and separation system uses food-grade lubricants to avoid contaminating plastic components (which are often recycled into new battery casings). For businesses prioritizing ESG goals, GTR is a natural fit.

Based in Calgary, PRM understands the needs of recyclers in harsh climates. Their rotary furnace for paste reduction units are built with insulated panels and cold-weather start systems, ensuring reliable operation even in -30°C winters. “We tested PRM’s furnace in our Saskatchewan facility during a January cold snap,” says Tom Harris, owner of Northern Scrap Recyclers. “While our old furnace took 2 hours to reach operating temperature, PRM’s was ready in 45 minutes—saved us thousands in heating costs.” PRM also specializes in lead acid battery breaking and separation system components that are corrosion-resistant, a must in regions with high humidity or salt exposure (like coastal areas). Their “Arctic Series” breaking machines feature stainless steel blades and sealed electrical systems to prevent rust and short circuits.

PRM’s customer service is another draw. They maintain a parts warehouse in Edmonton, ensuring next-day delivery for most components, and offer free annual maintenance checks for the first five years. Their furnaces are also compatible with a range of fuel types (natural gas, propane, diesel), giving clients flexibility in areas with limited energy infrastructure. For recyclers in challenging environments, PRM’s “tough-as-nails” equipment is a game-changer.

For industrial-scale recyclers handling 2,000+ kg/hour of lead paste, UFI (based in Hamilton) is the go-to. Their UFI-5000 furnace is a beast: 12 meters long, 3 meters in diameter, and capable of processing 5 tons of paste per hour. What makes it efficient? A dual-drum design, where the inner drum rotates at high speed to mix paste evenly, and the outer drum insulates to minimize heat loss. UFI also offers a lead acid battery breaking and separation system with robotic arms for sorting, reducing labor costs by 40%. “We supply some of the largest recycling plants in North America,” says UFI sales director Mike Chen. “Our furnaces are designed to run 24/7, with minimal downtime for maintenance.” To back that up, UFI provides a “performance guarantee”: if their furnace doesn’t meet the promised recovery rate (99.5%+ for lead), they refund 10% of the purchase price.

UFI’s systems aren’t cheap—starting at $1.2 million—but they’re built to last. The furnace drums are made from heat-treated alloy steel with a 10-year lifespan, and the air pollution control system includes redundant scrubbers to ensure compliance even if one unit needs maintenance. For mega-plants, UFI is worth the investment.

Ever wished you could take your furnace to the batteries, instead of hauling batteries to the furnace? PRT, based in Winnipeg, makes that possible with their line of portable rotary furnace for paste reduction units. The PRT-Portable 300, for example, fits on a standard flatbed trailer, weighs 8 tons, and can process 300 kg/hour of paste. It’s powered by a diesel generator (or can plug into grid power) and includes a built-in air pollution control system with a compact scrubber. “We work with mining companies and remote communities that have small battery stockpiles,” explains PRT founder Lisa Wong. “Instead of paying to transport batteries hundreds of kilometers, they bring our furnace on-site, process the paste, and ship only the lead ingots—saving time and money.” PRT’s portable units are also popular with disaster relief teams, who use them to safely recycle batteries from flood or fire-damaged areas.

Despite their small size, PRT’s furnaces don’t skimp on safety. They include automatic shutoff systems for overheating, gas leak detectors, and emergency stop buttons, and are certified by Transport Canada for road travel. For flexibility, PRT is unbeatable.

While most suppliers focus on the furnace itself, NCS (Toronto) has revolutionized furnace efficiency with a tiny component: ceramic balls. Their nano ceramic ball for ball mill equipment is used in the paste grinding stage before melting, reducing particle size by 30% and allowing for faster, more complete reduction in the furnace. “Smaller paste particles have more surface area, so they react faster with the reducing agent,” explains NCS materials scientist Dr. Alan Kim. “Our nano ceramic balls are 50% harder than traditional steel balls, so they last 3x longer and don’t contaminate the paste with iron.” NCS also supplies microcrystalline ceramic ball equipment for clients who need larger particles, and offers custom ball sizes for unique paste compositions.

Though not a furnace manufacturer, NCS partners with many of the suppliers on this list to integrate their ceramic balls into complete systems. “We’ve worked with Northern Recycling Technologies to boost their furnace efficiency by 12%,” says Dr. Kim. For recyclers looking to optimize existing equipment, NCS’s ceramic balls are a low-cost upgrade with big returns.

While CleanAir doesn’t make furnaces, their air pollution control system equipment is so advanced that many furnace manufacturers (including NRT and UFI) recommend it as an add-on. Based in Ottawa, CleanAir specializes in emissions control for heavy industry, and their recycling-specific systems are second to none. Their CA-9000 system includes a baghouse filter, wet scrubber, and thermal oxidizer that together remove 99.97% of particulates, 95% of sulfur dioxide, and 90% of volatile organic compounds (VOCs). “We designed the CA-9000 after noticing a gap in the market,” says CleanAir CEO Sarah Johnson. “Many recyclers were using generic pollution control systems that couldn’t handle the unique emissions from lead paste melting.” CleanAir’s system also includes real-time emissions monitoring with cloud connectivity, so operators can track data from anywhere and generate compliance reports with a click.

CleanAir systems are certified by the EPA (U.S.), EC (EU), and Canada’s Environment and Climate Change Canada, making them ideal for global clients. They also offer retrofitting services for older furnaces, helping recyclers upgrade without replacing their entire setup. For peace of mind on emissions compliance, CleanAir is the gold standard.

For small-scale recyclers or labs needing to process just 100-300 kg/hour of paste, Mini-Melt (Vancouver) offers compact rotary furnace for paste reduction units that are affordable and easy to operate. Their Mini-Melt 100, priced at under $100,000, is popular with universities, research facilities, and small scrap yards. It features a user-friendly touchscreen interface, automatic paste feeding, and a built-in filter press equipment for small-batch acid processing. “We wanted to make lead recycling accessible to smaller operations,” says Mini-Melt founder John Lee. “Our furnace can be operated by one person with minimal training, and we offer financing options to keep upfront costs low.” Mini-Melt also provides free technical support via video call, a boon for clients with limited in-house expertise.

Despite its size, the Mini-Melt 100 doesn’t compromise on safety. It includes a fume hood, emergency stop, and overheat protection, and meets Canada’s CSA safety standards. If you’re just starting out or need a small-scale solution, Mini-Melt is worth considering.
