Top 10 Paste Reduction Smelting Furnace Suppliers in Singapore in 2025

Founded back in 2010, EcoSmelt has been a staple in Singapore’s recycling tech scene. What sets them apart? Their focus on rotary furnace for paste reduction l lead acid battery recycling plant systems. These aren’t your run-of-the-mill furnaces – they’re designed with a rotating drum that ensures even heating, which means better lead recovery rates (we’re talking 98%+ here). And they don’t stop at the furnace. Most of their packages include filter press equipment to handle wastewater and sludge, plus air pollution control system equipment that uses advanced scrubbers to cut down on emissions. I spoke to a client in Malaysia who switched to EcoSmelt last year, and they mentioned their energy bills dropped by 15% – that’s a big deal for a high-heat process like smelting.

Another thing to love? Their after-sales service. They offer 24/7 technical support, and their team even helps with installation and staff training. For small to medium-sized recycling plants, their “EcoStart” package is perfect – it’s a compact setup that can handle 500-1,000 kg/hour, which is just right if you’re scaling up. Larger operations might opt for the “EcoMax” series, which tops out at 3,000 kg/hour. Either way, you’re getting a system that’s built to last.

GreenMelt is the new kid on the block, founded in 2018, but don’t let their age fool you. They’ve quickly made a name for themselves with their innovative take on paste reduction. Their flagship product? The “MeltPro-R” furnace, which uses medium-frequency induction heating instead of traditional fuel burners. Why does that matter? Induction heating is faster to start up (cuts pre-heating time by 30%) and more precise, so you can control the temperature down to the degree. That precision translates to less waste and higher purity lead output.

What I really like about GreenMelt is their commitment to customization. Let’s say you already have a lead acid battery recycling equipment setup but need to upgrade just the furnace – they’ll design a unit that fits your existing layout. One client in Thailand told me they wanted to add a furnace to their plant without disrupting their current workflow, and GreenMelt’s engineers came up with a side-by-side installation that had them up and running in under a week. Plus, their air pollution control system equipment is modular, so you can add components like activated carbon filters or electrostatic precipitators as regulations get stricter.

Capacity-wise, they cover the mid-to-high range: 1,000-4,000 kg/hour. Their “MeltPro-S” is a favorite for plants that process both lead-acid batteries and other scrap metals, thanks to its adjustable temperature settings. And if you’re worried about space? Their furnaces are more compact than most competitors, with a smaller footprint that saves valuable factory floor space.

Urban Metal Recovery Systems (UMRS) is all about urban recycling – think smaller plants located in or near city centers where space is tight. Their paste reduction furnaces are designed to be ultra-compact, but don’t let the size fool you. Their “UrbanMelt Mini” can handle 300-800 kg/hour, which is ideal for facilities that don’t have room for massive industrial setups. But here’s the clever part: They’ve integrated the furnace with a built-in filter press equipment unit, so you don’t need separate space for wastewater treatment. It’s like a one-stop shop in a box.

UMRS also prides itself on using recycled materials in their own manufacturing – over 60% of the steel in their furnaces comes from scrap metal. That’s a nice touch for companies that want to align their supply chain with their sustainability goals. Their air pollution control system equipment is another highlight – it uses a dual-stage filtration process (bag filters + wet scrubbers) that’s been tested to meet Singapore’s strict NEA emission standards, which are some of the toughest in the region.

Clients love their transparent pricing – no hidden fees for installation or training. One small recycler in Jurong told me, “With UMRS, what you see is what you get. The quote they gave me was the final price, and they even threw in a free maintenance check after six months.” For startups or businesses with limited budgets, UMRS offers flexible financing options too, which is a big plus in a capital-intensive industry.

SmeltWorks is a regional heavyweight, with offices in Singapore, Indonesia, and Vietnam. Their claim to fame? Their “MegaMelt” series of paste reduction furnaces, which are built for mega-capacity operations. We’re talking 5,000-8,000 kg/hour – that’s enough to process truckloads of battery paste every day. These furnaces are beasts, but they’re surprisingly energy-efficient, thanks to their heat recovery systems that reuse waste heat to pre-heat incoming materials. It’s a simple idea, but it cuts energy use by up to 20% compared to standard models.

What really stands out, though, is their integration with lead refinery furnace l lead acid battery recycling systems. If you want to take your recycled lead from “crude” to “refined” (ready for use in new batteries), SmeltWorks can hook you up with a complete line: paste reduction furnace → refinery furnace → casting machine. It’s a seamless process that saves time and reduces handling. Their air pollution control system equipment is also top-tier – they use a combination of thermal oxidizers and catalytic converters to tackle even the trickiest emissions, which is a must for plants in densely populated areas.

Of course, all this comes with a higher price tag, but for large-scale operations, the ROI is there. A client in Batam, Indonesia, reported recouping their investment in under 2 years, thanks to higher production volumes and lower operating costs. SmeltWorks also offers long-term service contracts, so you can lock in maintenance costs for up to 5 years – no surprises down the line.

CleanCycle is all about innovation – they’re the ones pushing the envelope with new furnace designs. Their latest offering? A hybrid furnace that uses both gas and electricity for heating. Why hybrid? Because it gives you flexibility. If gas prices spike, you can switch to electricity (or vice versa), which helps stabilize operating costs. It’s a small tweak, but it makes a big difference for budget planning.

They also specialize in lead acid battery recycling equipment that’s easy to upgrade. Let’s say you start with a 1,000 kg/hour furnace, but a year later, you need to boost capacity to 1,500 kg/hour. CleanCycle can retrofit your existing unit with a larger heating chamber and upgraded controls, instead of making you buy a whole new furnace. That’s a huge cost-saver. Their filter press equipment is another standout – it uses automated cake discharge, so you don’t need manual labor to remove sludge, which cuts down on labor costs and improves safety.

CleanCycle is also big on data. Their furnaces come with IoT sensors that track temperature, energy use, and emission levels in real time. You can monitor everything from a smartphone app, which makes troubleshooting a breeze. One plant manager in Singapore told me, “I can check the furnace status from home – if there’s an issue, I get an alert, and the tech team is already on it before I even get to the office.” For businesses that value tech and efficiency, CleanCycle is a no-brainer.

MetroRecycling Tech is a family-owned business that’s been around since 2005, and they’ve built their reputation on reliability. Their furnaces are known for minimal downtime – most clients report 95%+ uptime, which is crucial in a 24/7 operation. How do they do it? Heavy-duty construction, high-quality components (they source parts from Europe and Japan), and a simple design that’s easy to maintain. No fancy bells and whistles here – just a solid, workhorse furnace that gets the job done.

They offer a range of capacities, from 500 kg/hour (perfect for small plants) up to 3,000 kg/hour. Their “MetroMelt Basic” is a favorite for startups – it’s affordable, easy to install, and comes with a 5-year warranty on the heating elements. For larger operations, the “MetroMelt Pro” adds features like automatic feed systems and advanced temperature controls. And yes, they include air pollution control system equipment as standard – no need to buy it separately. Their scrubbers are designed to handle high sulfur content (common in battery paste), which is a must for meeting emission limits.

What really wins people over, though, is their customer service. The owner, Mr. Tan, is known for personally visiting clients to check on their systems. One recycler in Johor Bahru said, “When our furnace had a minor issue last month, Mr. Tan drove down the next day to help fix it himself. You don’t get that kind of dedication from big corporations.” For businesses that value a personal touch and reliability, MetroRecycling Tech is hard to beat.

ASS is all about specialization – they don’t try to do everything, but what they do, they do extremely well: high-temperature paste reduction furnaces for tough materials. If you’re processing old, corroded batteries with lots of impurities, their furnaces can handle it. They use a unique refractory lining (made from alumina-silica) that can withstand temperatures up to 1,200°C without cracking, which extends the furnace’s lifespan by 3-5 years compared to standard linings.

They also offer custom air pollution control system equipment for specific contaminants. For example, if your paste has high levels of chlorine (from certain battery types), they’ll design a scrubber with a special chemical additive to neutralize it. It’s this attention to detail that makes them a go-to for niche recycling operations. Their filter press equipment is equally specialized – they offer membrane filter presses that squeeze out more water from sludge, reducing waste volume by up to 40%.

ASS isn’t the cheapest option, but you’re paying for expertise. Their team includes metallurgists and chemical engineers who can help you optimize your process, from paste preparation to lead casting. One client who processes military-grade batteries told me, “ASS didn’t just sell us a furnace – they helped us redesign our entire workflow, which boosted recovery rates by 5%.” For complex recycling challenges, ASS is worth every penny.

MetalCycle is the supplier for businesses that prioritize sustainability in every step. Their furnaces are designed to be carbon-neutral – they use renewable energy (solar or biogas) for power, and they offset any remaining emissions by investing in reforestation projects. It’s a great selling point for companies that want to market their recycling services as “green” to clients and regulators.

But they don’t sacrifice performance for sustainability. Their “EcoMelt” furnace can handle 800-2,500 kg/hour and has a lead recovery rate of 97.5%, which is on par with non-green competitors. They also offer a closed-loop water system – the water used in cooling and cleaning is treated with their filter press equipment and recycled back into the process, so you use almost no fresh water. That’s a big deal in water-scarce regions like Singapore.

MetalCycle also offers training programs for operators on sustainable practices, like how to minimize waste and optimize energy use. It’s a holistic approach that goes beyond just selling equipment. For businesses that want to align with global sustainability goals (like the UN’s SDGs), MetalCycle is a perfect partner. Plus, their furnaces are eligible for Singapore’s Green Technology Fund, which can cover up to 30% of the purchase cost – that’s a nice incentive.

Precision Smelt lives up to its name – their furnaces are all about accuracy. They use digital PID controllers that maintain temperature within ±1°C, which is crucial for consistent lead quality. If you’re selling your recycled lead to battery manufacturers (who have strict purity standards), this level of precision is non-negotiable. Their furnaces also have automatic sampling systems that test the lead every 15 minutes, so you can catch quality issues early.

They specialize in small to medium capacities (300-1,500 kg/hour), but what they lack in size, they make up for in control. Their “PrecisionMelt” series comes with a user-friendly touchscreen interface that even new operators can learn quickly. You can pre-program recipes for different types of battery paste (e.g., car batteries vs. industrial batteries), which saves time when switching between materials. And their air pollution control system equipment is equally precise – it uses real-time emission monitoring to adjust fan speeds and chemical dosages, ensuring you never exceed regulatory limits.

Precision Smelt also offers a unique “Try Before You Buy” program – they’ll set up a demo furnace at your site for a week, so you can test it with your actual materials before committing. It’s a risk-free way to make sure the furnace works for your specific needs. One electronics recycler in Singapore said, “The demo convinced us – we saw firsthand how consistent the lead quality was, and the operators picked up the controls in a day.” For businesses that value precision and low training costs, this is a huge advantage.

Rounding out our list is GlobalRecycler Tech, a subsidiary of a larger international group with operations in Europe and Asia. What they bring to the table is global expertise – they’ve adapted their European-designed furnaces to meet Asian needs, like higher humidity tolerance and compatibility with local fuel sources. Their “GlobalMelt” furnace is a bestseller, with capacities ranging from 1,000-5,000 kg/hour, making it versatile for both mid-sized and large plants.

GlobalRecycler Tech is also a one-stop shop for lead acid battery recycling equipment . Need a battery breaker to crush old batteries before smelting? They’ve got it. Need a conveyor system to move paste to the furnace? They’ve got that too. This vertical integration means you’re dealing with one supplier for your entire line, which simplifies communication and reduces coordination headaches. Their filter press equipment is imported from Germany, known for its durability, and their air pollution control system equipment meets both EU and Singapore standards, which is great if you export recycled lead to Europe.
