Top 10 Paste reduction smelting furnace Suppliers, Manufacturers, Wholesalers and Traders in Germany

Nestled in the heart of Berlin's industrial district, Berlin Recycling Technik GmbH (BRT) has been a cornerstone of the city's engineering scene since 1985. What began as a small workshop repairing aging recycling machines has grown into a full-service manufacturer with a global footprint. Walk into their factory today, and you'll find a team of 40+ engineers and technicians collaborating on everything from 3D designs to on-site installations. BRT's claim to fame? Their rotary furnace for paste reduction, a machine they've refined over three decades. Unlike off-the-shelf models, BRT's furnaces are built to order, with features like adjustable temperature controls and automated slag removal tailored to each client's input materials. "We once worked with a recycling plant in Poland that processed batteries from electric bikes—smaller, lighter, and with different paste compositions than car batteries," explains Hans Müller, BRT's sales director. "We modified the furnace's internal lining to handle the lower heat load and added sensors to monitor sulfur emissions in real time. That's the difference between selling equipment and solving problems."

Beyond furnaces, BRT integrates air pollution control system equipment into every project, ensuring clients meet Germany's strict TA-Luft emissions standards. Their latest innovation, a compact scrubber system, uses 30% less water than traditional models—a boon for plants in water-scarce regions. And with a 24/7 support hotline staffed by German-speaking technicians, it's no wonder BRT counts clients in 28 countries, from Turkey to Tanzania. "Our clients don't just buy a furnace; they join a family," Müller adds with a smile. "Last year, we flew a technician to Kenya to help a client troubleshoot a sensor issue—no extra charge. That's how we build trust."

In Munich, where innovation and sustainability go hand in hand, Munich Eco-Engineering Works (MEEW) has made a name for itself by reimagining lead acid battery recycling as a closed-loop system. Founded in 2001 by a team of former BMW engineers, MEEW brings automotive precision to the recycling world. Their flagship offering? A fully integrated lead acid battery recycling equipment line that starts with battery breaking and ends with pure lead ingots—all under one roof. At the heart of this line is their rotary furnace for paste reduction, designed with energy efficiency in mind. "We use waste heat from the furnace to preheat incoming paste, cutting fuel costs by up to 25%," says Sophie Wagner, MEEW's sustainability director. "It's not just good for the planet; it's good for our clients' bottom lines."

What truly sets MEEW apart, though, is their focus on upstream and downstream processes. Pair their furnace with their filter press equipment, and you'll capture 99% of sulfuric acid for reuse in new batteries—a feature that has made them a favorite among European recycling plants aiming for zero-waste certifications. Their Munich headquarters also houses a demo center where clients can test equipment with their own battery samples before committing. "A client from France once spent three days here, running 500kg of paste through our furnace to tweak settings," Wagner recalls. "By the end, they had data on emissions, lead purity, and energy use—hard numbers that helped them secure funding for their plant. That's the transparency we believe in." With clients like Veolia and Remondis on their roster, MEEW isn't just selling machines; they're building the future of circular manufacturing.

Hamburg, Germany's gateway to the North Sea, has long been a hub for heavy industry—and Hamburg Industrial Solutions (HIS) embodies that legacy. Founded in 1968, HIS started by supplying machinery to the shipping industry before pivoting to recycling equipment in the 1990s, when the EU began cracking down on battery waste. Today, they're known for building some of the largest paste reduction furnaces in Europe, with capacities ranging from 500kg/hour to 5,000kg/hour. "If you need to process 10,000 batteries a day, we've got you covered," says Karl Schmidt, HIS's project manager. Their rotary furnace for paste reduction is a behemoth, but don't let its size fool you—it's surprisingly nimble. Thanks to a touchscreen control panel, operators can adjust parameters like rotation speed and air flow with the tap of a finger, reducing training time for new staff.

HIS also excels in (complementary equipment), including hydraulic press machines that compact lead scrap into briquettes for easier handling. Their recent partnership with a Dutch tech firm has yielded a smart furnace system that uses AI to predict maintenance needs, cutting downtime by 40%. "Last year, a client in Spain had a bearing failure—but our system flagged it three weeks earlier, giving them time to order parts and schedule repairs during a planned shutdown," Schmidt notes. With a warehouse in Hamburg port, HIS can ship equipment to any corner of the globe in under 48 hours, and their multilingual support team (fluent in German, English, Spanish, and Arabic) ensures no client feels left in the dark. For large-scale operations, HIS isn't just a supplier—it's a strategic partner.

In Cologne, a city known for its eco-conscious startups, Cologne Green Tech Innovations (CGTI) is challenging the status quo with a focus on low-carbon recycling. Founded in 2010 by a trio of environmental engineers, CGTI might be the youngest supplier on this list, but they're quickly making up for lost time with cutting-edge technology. Their specialty? Air pollution control system equipment that goes above and beyond regulatory requirements. "Most suppliers treat emissions control as an afterthought—we build it into the core of our systems," explains Lena Hoffmann, CGTI's founder. Take their paste reduction furnace: it's paired with a dual-stage scrubber that first neutralizes sulfur dioxide with lime and then filters particulates through a HEPA-like membrane, resulting in emissions so clean they're often lower than ambient air in urban areas.

CGTI also leads the pack in wet process equipment, which uses water-based separation to recover lead without generating dust—a game-changer for plants near residential areas. Their "EcoLine" furnace, launched in 2022, runs on biogas, slashing carbon emissions by 60% compared to diesel-powered models. "We tested it for six months at a plant in Berlin, and the operator saved €120,000 on fuel costs alone," Hoffmann says. Despite their focus on innovation, CGTI keeps costs in check by using modular designs—clients can start with a basic furnace and add scrubbers or automation later as their business grows. It's this blend of sustainability and affordability that has made CGTI a hit with startups and social enterprises, including a worker-owned recycling co-op in Portugal. "We're not just building machines," Hoffmann adds. "We're building a recycling future that's accessible to everyone."

Stuttgart is synonymous with engineering excellence, and Stuttgart Precision Machinery (SPM) lives up to that reputation. Founded in 1952 as a manufacturer of machine tools, SPM pivoted to recycling equipment in the 1980s, leveraging its expertise in precision engineering to craft some of the most durable furnaces on the market. Walk through their archives, and you'll find maintenance records for furnaces installed in the 1990s that are still running today—a testament to their build quality. SPM's lead refinery furnace is a marvel of German engineering, with a cast-iron hearth that can withstand temperatures up to 1,200°C and a gearbox designed to last 20+ years with minimal maintenance. "We use the same metallurgy in our furnace gears as we did in the machine tools we built for Mercedes-Benz," says Dieter Koch, SPM's chief engineer. "If it can handle the stress of an automotive factory, it can handle a recycling plant."

What makes SPM unique, though, is its diversification beyond lead acid batteries. The company also produces circuit board recycling equipment, allowing clients to process e-waste alongside batteries and maximize their revenue streams. "A recycling plant in Austria uses our furnace for lead and our shredders for circuit boards—they're now one of the most profitable facilities in Central Europe," Koch notes. SPM also offers training programs for operators, with a week-long course at their Stuttgart campus covering everything from furnace calibration to troubleshooting. For clients who can't travel, their virtual training sessions use VR headsets to simulate hands-on repairs. It's this commitment to long-term partnerships that has kept SPM relevant for over seven decades. "We don't just sell you a furnace," Koch says. "We make sure you know how to get the most out of it—today, tomorrow, and 20 years from now."

Düsseldorf, a city at the crossroads of Germany's industrial heartland, is home to Düsseldorf Recycling Systems (DRS), a supplier known for its flexible, modular approach to recycling. Founded in 1995 by a team of process engineers, DRS specializes in building systems that grow with their clients. "Not every plant needs a 5,000kg/hour furnace on day one," says Petra Weber, DRS's marketing director. "We start with the basics and add components as our clients scale." Their filter press equipment is a prime example: a compact, skid-mounted unit that can be integrated into existing lines or paired with DRS's own paste reduction furnace. Unlike bulkier models, DRS's filter presses are easy to disassemble for cleaning, cutting maintenance time by half.

DRS also shines in material handling, with plastic pneumatic conveying systems that transport shredded battery plastic from the breaking line to the furnace with minimal dust. "We designed our conveyors to work with any furnace, not just ours," Weber explains. "A client in Italy bought our conveyors to upgrade their 10-year-old furnace from another supplier—and they're now saving €50,000 a year on labor costs." DRS's customer service is equally flexible, with options for rent-to-own financing and extended warranties (up to 5 years) for clients in emerging markets. "We worked with a startup in Nigeria that couldn't afford a full furnace upfront," Weber recalls. "We structured a payment plan tied to their production volume—they paid more as they recycled more. Now, they're one of our biggest clients in Africa." It's this willingness to adapt that has made DRS a favorite among entrepreneurs looking to break into the recycling industry.

Frankfurt, Germany's financial capital, might not be the first place you'd expect to find a recycling equipment manufacturer—but Frankfurt Environmental Technologies (FET) has thrived here since 1987 by combining industrial know-how with business acumen. FET specializes in turnkey plants, handling everything from design and installation to staff training and regulatory compliance. "We take the stress out of building a recycling facility," says Andreas Berger, FET's project director. "A client in France once told us, 'We just turned the key, and the plant started running'—that's our goal." FET's rotary furnace for paste reduction is the centerpiece of these plants, but what truly impresses clients is the integration of water process equipment. Their closed-loop water system recycles 95% of the water used in washing and cooling, making FET plants ideal for regions with strict water regulations.

FET also offers a unique "Performance Guarantee" program: if a plant doesn't meet the promised lead recovery rate (typically 98%+) within the first year, FET sends a team to optimize the system at no cost. "We stand behind our equipment," Berger says. "Last year, a plant in Greece was struggling with low recovery—we discovered their input paste had higher sulfate levels than expected. We adjusted the furnace's temperature profile and added a secondary reduction step, and now they're exceeding their targets." With a portfolio that includes plants in 15 countries, FET has become a trusted partner for governments and NGOs funding recycling initiatives in developing nations. Their recent project in Vietnam, a $12 million plant funded by the EU, is expected to process 10,000 tons of batteries annually and create 50 local jobs. "Recycling isn't just about machines," Berger adds. "It's about building sustainable communities."

Leipzig, a city with a rich industrial heritage in Saxony, is home to Leipzig Heavy Machinery Co. (LHMC), a manufacturer that prides itself on rugged, no-nonsense equipment built for the toughest environments. Founded in 1946 as a state-owned enterprise, LHMC was privatized in 1990 and has since focused on machines that can handle the gritty reality of recycling yards. Their hydraulic briquetter equipment, for example, can compress lead scrap into dense briquettes even when mixed with dirt, plastic, or other contaminants—a common issue in unsegregated waste streams. "We test our machines with the worst-case scenarios," says Ingrid Schulz, LHMC's quality control manager. "We once ran a batch of battery scrap that included nails and pieces of metal—our briquetter didn't even slow down."

LHMC's metal melting furnaces are equally robust, with a refractory lining that can withstand 500+ melts before needing replacement. "A plant in Russia uses our furnace to process batteries from military vehicles—extreme temperatures, heavy use, and minimal maintenance access," Schulz notes. "They've had it for five years, and we've only replaced the heating elements once." Despite their focus on durability, LHMC hasn't ignored innovation. Their latest briquetter model includes a touchscreen interface that logs production data, helping clients track efficiency and plan maintenance. And with a network of service centers across Eastern Europe, LHMC offers faster response times than many Western competitors in regions like Poland, Hungary, and the Czech Republic. "We build machines for people who get their hands dirty," Schulz adds. "They don't want frills—they want reliability. That's what we deliver."

Dresden, a city rebuilt from the ashes of World War II, has a history of resilience—and Dresden Clean Energy Systems (DCES) embodies that spirit. Founded in 1992 by former East German scientists, DCES has made a name for itself by turning energy efficiency into a competitive advantage. Their air pollution control system equipment is a case in point: DCES's electrostatic precipitators use 40% less electricity than conventional models, thanks to a proprietary electrode design developed in partnership with Dresden University of Technology. "We're scientists at heart," says Dr. Anja Neumann, DCES's R&D director. "We spend 15% of our revenue on research, and it shows."

DCES also leads the way in dry process equipment, which uses air classification instead of water to separate lead particles. This not only saves water but also eliminates the need for wastewater treatment, making DCES systems popular in arid regions like the Middle East. Their "EcoDry" furnace, launched in 2021, uses solar panels to power its control systems, further reducing its carbon footprint. "A client in Jordan installed our EcoDry furnace and now qualifies for green energy subsidies," Neumann notes. "It's a win-win: they save money, and we reduce emissions." DCES also offers remote monitoring via a cloud platform, allowing engineers in Dresden to troubleshoot issues in real time. "Last month, we diagnosed a sensor failure in a furnace in Morocco within 10 minutes of the alert," Neumann says. "We guided the local technician through the repair over video call—no need for a costly service trip." It's this blend of innovation and practicality that has made DCES a favorite among forward-thinking recycling companies.

Bremen, a port city with a global outlook, is home to Bremen Industrial Traders (BIT), a wholesaler and trader that bridges the gap between manufacturers and clients worldwide. Founded in 1975, BIT doesn't build equipment itself—instead, it partners with top German manufacturers (including some on this list) to offer a curated selection of machinery. "We're the middlemen who add value," says Klaus Fischer, BIT's managing director. "A client in India might not know which furnace is right for their climate or input materials—we do the legwork, comparing specs, negotiating prices, and ensuring after-sales support." BIT specializes in lead acid battery breaking and separating plants, bundling furnaces, shredders, and conveyors into packages tailored to each market. For example, their "Tropical Package" includes furnaces with corrosion-resistant coatings and extra ventilation for hot, humid climates.

BIT also excels in sourcing hard-to-find equipment, including filter press equipment from small manufacturers in Bavaria and air pollution control systems from startups in Berlin. "We once helped a client in Brazil find a specialized scrubber that removes mercury from lead fumes—something most suppliers don't carry," Fischer recalls. "We tracked it down to a family-owned workshop in Dresden and arranged for custom modifications." With offices in Dubai, Singapore, and Mexico City, BIT offers localized support in 12 languages, ensuring clients never feel lost in translation. And with a network of 50+ service technicians worldwide, they can dispatch help within 48 hours to most regions. "Our job is to make German engineering accessible globally," Fischer adds. "Whether you're in Nigeria or Norway, you deserve the same quality equipment and support. That's our promise."
