1. EcoRecycle Tech Pte Ltd: Where Water Meets Precision
When it comes to blending water treatment with circuit board recycling, EcoRecycle Tech isn’t just a supplier—they’re a problem solver. Founded in 2010, this Singapore-based company has made a name for itself by understanding that the key to responsible recycling lies in clean water management. “We don’t just sell machines,” says their lead engineer, Mr. Lim. “We sell peace of mind. Every ｄｒｏｐ of water that leaves our clients’ plants is cleaner than when it came in.” And they back that claim with some seriously impressive gear.
Their star products?
Circuit board recycling equipment paired with state-of-the-art
water process equipment. Imagine a system that can handle 500 to 2000 kg of circuit boards per hour, all while treating the water used in the separation process to near-drinking standards. How do they do it? Their dual-stage filtration system first traps large particles (think plastic shards, metal scraps) before sending the water through a second stage of fine membranes that catch even microscopic contaminants. Add in their pH neutralization systems, which ensure no acidic or alkaline water harms local ecosystems, and you’ve got a setup that’s as tough on waste as it is gentle on the planet.
What Makes Them Stand Out?
Clients rave about their after-sales support. “We had a minor hiccup with our filtration unit six months in,” says a local recycling plant manager. “EcoRecycle sent a team within 24 hours, fixed it, and even gave us a free training session on maintenance. They don’t just walk away after the sale—they’re in it for the long haul.” Plus, their equipment is modular, meaning small plants can start with a basic setup and scale up as they grow. For a city like Singapore, where space is precious, that flexibility is a game-changer.
2. Green Circuit Solutions: Dry Process Expertise with a Water-Smart Twist
If you’ve heard of the WCBD-2000A circuit board recycling plant, you’ve probably heard of Green Circuit Solutions. This company has built its reputation on
dry process equipment that minimizes water use—but when water is needed, they make sure it’s used wisely. “Dry processes are great for reducing water consumption, but even the best dry systems generate some wastewater from cleaning and cooling,” explains their sustainability director, Ms. Tan. “That’s where our water treatment tech shines. We turn ‘used’ water into ‘reusable’ water, cutting our clients’ water bills by up to 40%.”
The WCBD-2000A is their pride and joy—a beast of a machine that can process 800 to 1800 kg of circuit boards per hour using air classification and electrostatic separation (no water needed for the main process). But when water does enter the picture (like in cleaning the equipment or cooling the motors), their closed-loop water recycling system kicks in. Water is collected, filtered through sedimentation tanks to remove debris, and then pumped back into the system. It’s a closed loop, meaning almost no water is wasted or released. “We had a client in Jurong who was using 10,000 liters of water a day before switching to our system,” Ms. Tan adds. “Now? They use 2,000 liters—all recycled. That’s not just good for the environment; it’s good for their bottom line.”
Why Clients Choose Them
It’s simple: reliability. Green Circuit’s equipment is built to last, with a 5-year warranty on all major components. “We once had a client whose WCBD-2000A ran 24/7 for three years straight—no breakdowns, just regular maintenance,” Ms. Tan laughs. “They thought we’d oversold the durability, but we delivered. And with Singapore’s strict environmental regulations, their closed-loop water system ensures clients never run afoul of the law. No fines, no headaches—just smooth, sustainable recycling.”
3. CleanTech Environmental Engineering: Wet Process Wizards
Wet process equipment gets a bad rap for being water-heavy, but CleanTech Environmental Engineering is here to change that narrative. “Yes, wet processes use more water than dry ones, but they’re often more efficient at separating precious metals,” says their technical lead, Mr. Raj. “The trick is to treat that water so thoroughly that you can reuse it indefinitely. Our systems don’t just process circuit boards—they create a water cycle that’s almost self-sustaining.”
Their compact granulator with dry separator is a hit with small to mid-sized plants, but it’s their water treatment tech that steals the show. Reverse osmosis membranes strip contaminants down to the molecular level, while activated carbon adsorption removes any remaining organic compounds. The result? Water that’s clean enough to be reused in the process, over and over. “One of our clients in Tuas was spending SGD 15,000 a month on water and wastewater disposal,” Mr. Raj shares. “After installing our system, that number dropped to SGD 3,000. That’s a 80% savings—money they can now invest in growing their business.”
A Client Story That Speaks Volumes
“We were nervous about switching to wet processing because of the water costs,” admits a manager at a local e-waste facility. “CleanTech walked us through every step, showed us the numbers, and even let us test their equipment for a week. Now, we’re extracting 15% more gold from our circuit boards than we did with dry processing, and our water bill is lower than ever. They didn’t just sell us equipment—they gave us a better way to do business.” For CleanTech, that’s the goal: proving that sustainability and profitability can go hand in hand.
4. Sustainable Electronics Recycling (SER): Zero-Liquid Discharge Champions
SER doesn’t just aim to treat water—they aim to eliminate wastewater entirely. Their zero-liquid discharge (ZLD) systems are the stuff of legend in Singapore’s recycling scene. “Why send water to a treatment plant when you can reuse every ｄｒｏｐ?” asks their founder, Mr. Wong. “ZLD is the future, and we’re already living in it.” Their
circuit board recycling equipment, paired with ion exchange resins and UV disinfection, ensures that no water leaves their clients’ facilities—everything is filtered, treated, and sent back into the process.
With a capacity range of 600 to 2200 kg/hour, SER’s systems are built for scale. But even their smaller setups pack a punch. “We worked with a community recycling center in Bedok that processes just 600 kg/hour,” Mr. Wong recalls. “They were worried ZLD would be too expensive, but we designed a compact system that fit their space and budget. Now, they’re a model for small-scale sustainability—proof that you don’t need a huge plant to make a huge difference.”
The SER Promise
“We guarantee that with our ZLD systems, you’ll never pay a wastewater disposal fee again,” Mr. Wong says. “And if you do, we’ll cover the cost. That’s how confident we are in our tech.” Clients love that peace of mind, especially in a regulatory environment as strict as Singapore’s. When you partner with SER, you’re not just getting equipment—you’re getting a promise: a promise to keep your plant compliant, efficient, and 100% water-smart.
5. EcoTech Systems Pte Ltd: Balancing Dry and Wet for Maximum Efficiency
EcoTech Systems knows that one size doesn’t fit all. That’s why they offer both dry process and
wet process equipment, tailoring each solution to their clients’ needs—with water treatment always at the core. “Some materials do better with dry separation, others with wet,” explains their sales manager, Mr. Chen. “Our job is to find the right mix, then build a water treatment system that supports it seamlessly. It’s like being a chef—you don’t use the same recipe for every dish, but you always make sure the ingredients work together.”
Their membrane bioreactors (MBRs) are a standout feature. These systems use bacteria to break down organic pollutants in wastewater, then pass the water through ultrafiltration membranes to remove any remaining solids. The result is water that’s not just clean for reuse, but also rich in nutrients that can be used as fertilizer (with proper treatment, of course). “We had a client who started using the treated water to irrigate their office plants,” Mr. Chen chuckles. “Now, their lobby is a mini jungle—and it’s all thanks to recycled circuit board water. Talk about a green office!”
Why Flexibility Matters
“Singapore’s recycling needs are evolving,” Mr. Chen notes. “One year, a plant might focus on old computer circuit boards; the next, they might shift to smartphone boards, which have different compositions. Our equipment adapts. Add a dry separator here, tweak the water treatment filters there, and you’re ready for whatever comes next. That adaptability is key to staying competitive in this industry.” And with their 24/7 tech support hotline, clients never feel stuck. “We had a client call at 2 a.m. with a water flow issue,” Mr. Chen says. “Our tech walked them through the fix over the phone in 15 minutes. No downtime, no panic—just solutions.”
6. PureCycle Innovations: Electrocoagulation for the Win
PureCycle Innovations is all about innovation—and their electrocoagulation technology is a prime example. “Traditional water treatment uses chemicals to coagulate contaminants,” explains their R&D head, Dr. Lee. “Electrocoagulation uses electricity instead. It’s more efficient, uses fewer chemicals, and produces less sludge. For circuit board recycling, where you’re dealing with heavy metals like lead and mercury, that’s a game-changer.”
Pair that with their dissolved air flotation (DAF) systems, which float contaminants to the surface for easy removal, and you’ve got a water treatment setup that’s both powerful and eco-friendly. Their circuit board recycling plant with dry separator (capacity 500–1500 kg/hour) is designed to work hand-in-hand with these systems, ensuring that every step of the process—from shredding to separation to water treatment—is optimized for sustainability.
The Science Speaks for Itself
“We tested our electrocoagulation system against traditional chemical treatment,” Dr. Lee says. “We found it removed 99.7% of heavy metals, compared to 95% with chemicals. And it used 30% less energy. For clients, that means cleaner water, lower costs, and a smaller carbon footprint. It’s a no-brainer.” And with Singapore’s push for green tech incentives, PureCycle’s clients often qualify for government grants to offset equipment costs. “We help them navigate the paperwork,” Dr. Lee adds. “We don’t just sell them a machine—we help them maximize their investment.”
7. E-Waste Solutions Singapore: Wet Process Specialists with a Heart for Small Businesses
Not every recycling plant in Singapore is a massive operation—and E-Waste Solutions Singapore caters to the little guys. Their
wet process equipment and hydraulic press machines are designed for small to mid-sized facilities, but that doesn’t mean they skimp on water treatment. “Smaller plants often think water treatment is too expensive, but we’ve made it affordable,” says their founder, Ms. Ng. “A basic system starts at under SGD 50,000, and the savings on water and disposal fees pay for it in less than a year.”
Their biological treatment systems use naturally occurring bacteria to break down organic matter in wastewater, while sand filtration catches any remaining particles. It’s simple, low-maintenance, and surprisingly effective. “We have a client in Ang Mo Kio who processes 300 kg/hour,” Ms. Ng shares. “Before us, they were dumping their wastewater (illegally, I might add—don’t do that!). Now, they’re fully compliant, and their neighbors have stopped complaining about the smell. It’s not just about following the law—it’s about being a good community member.”
Small But Mighty
“We don’t have the flashiest equipment, but we have the most heart,” Ms. Ng says. “Our team visits every client quarterly to check on their systems, answer questions, and make sure they’re getting the most out of their investment. For a small plant owner, that personal touch matters. They’re not just a number to us—they’re part of our family.” And with Singapore aiming to recycle 30% of e-waste by 2030, small plants are going to play a huge role. E-Waste Solutions is there to make sure they’re ready.
8. EcoFlow Tech Engineering: Dry Process Pros with a Thirst for Innovation
EcoFlow Tech Engineering is another heavyweight in
dry process equipment, but what sets them apart is their constant drive to innovate—especially when it comes to water. “Even dry processes need water for cooling and cleaning,” says their lead designer, Mr. Ooi. “We asked: How can we use less? How can we reuse more? The answer was our multi-media filtration system, which cleans water so effectively that we can reduce overall water use by 60% compared to standard dry systems.”
Their circuit board recycling plant WCBD-2000A (the same model Green Circuit uses) is paired with ozone oxidation, which uses ozone gas to disinfect water and break down stubborn contaminants. It’s faster than traditional chemical disinfection and leaves no harmful byproducts. “We installed this system at a plant in Jurong East last year,” Mr. Ooi says. “Their water use dropped from 5,000 liters/day to 2,000 liters/day. The plant manager called me to say, ‘I didn’t think dry process could get this water-efficient—you proved me wrong.’ That’s the best compliment we can get.”
Innovation Never Stops
“We’re already working on our next generation of water treatment tech,” Mr. Ooi teases. “Think solar-powered filtration systems that cut energy costs even further. In Singapore, where sunlight is abundant, that could be a game-changer. We believe that the future of recycling is not just about processing waste—it’s about doing it with zero impact on the planet. And we’re not waiting for the future—we’re building it now.”
9. GreenWave Environmental Pte Ltd: Water Process Equipment with a Green Thumb
GreenWave Environmental takes a unique approach to water treatment: they use nature. Their constructed wetlands—yes, actual plants—are part of their water treatment systems, working alongside advanced oxidation processes (AOP) to clean wastewater. “Plants are amazing filters,” explains their environmental scientist, Dr. Loh. “Reed beds, for example, absorb heavy metals and break down organic compounds. Pair that with AOP, which uses UV light and hydrogen peroxide to destroy contaminants, and you’ve got a system that’s both effective and beautiful. Clients love it—their plants look like gardens, not industrial facilities.”
Their
water process equipment and compact granulator with dry separator are designed to integrate seamlessly with these natural systems. “We had a client in Sentosa who wanted their recycling plant to blend in with the resort vibe,” Dr. Loh laughs. “Now, their wetlands are a tourist attraction! Kids love seeing the fish that swim in the treated water. It’s a great way to teach people about sustainability—show them, don’t just tell them.”
Nature + Technology = Perfect Partners
“Constructed wetlands aren’t just pretty—they’re tough,” Dr. Loh says. “They can handle fluctuations in wastewater flow and contaminant levels better than some mechanical systems. And they require almost no energy to run. For a company that prides itself on sustainability, that’s a win-win.” Plus, GreenWave offers free workshops on maintaining the wetlands, teaching clients how to prune the plants, test the water, and keep the system running smoothly. “Knowledge is power,” Dr. Loh adds. “The more our clients know, the more successful they’ll be.”
10. CircuitCycle Asia: Wet Process Warriors with a Focus on Metal Recovery
Rounding out our list is CircuitCycle Asia, a company that’s all about maximizing metal recovery—while keeping water clean, of course. Their
wet process equipment uses chemical leaching to extract precious metals from circuit boards, and their water treatment systems ensure those chemicals don’t end up in the environment. “Leaching is powerful, but it can be messy,” says their operations director, Mr. Teo. “Our magnetic separation and ultrafiltration systems make sure every ｄｒｏｐ of water is treated before it’s reused or released.”
Their systems are designed to recover 99% of gold, silver, and copper from circuit boards, which means less waste and more profit for their clients. “A client in Woodlands told us they increased their monthly revenue by SGD 20,000 after switching to our equipment,” Mr. Teo says. “The metal recovery rate went up, and their water costs went down. It’s a double win.” And with their ultrafiltration membranes, they can even recover some of the chemicals used in leaching, reducing both costs and environmental impact.
The Bottom Line (and the Green Line)
“At the end of the day, recycling is a business,” Mr. Teo admits. “Our clients need to make money to stay in business, and we help them do that while being green. It’s not an either/or—it’s a both/and. You can protect the planet and turn a profit. We prove that every day.” And with Singapore’s goal of becoming a zero-waste nation, companies like CircuitCycle Asia are going to be more important than ever. They’re not just recycling circuit boards—they’re recycling the idea that sustainability and profitability can’t coexist. Spoiler: they can, and they do.
There you have it—the top 10 suppliers in Singapore that are making water treatment and circuit board recycling work together for a greener future. From EcoRecycle Tech’s modular systems to GreenWave’s constructed wetlands, these companies are proving that when it comes to sustainability, innovation is key. Whether you’re a small plant just starting out or a large facility looking to upgrade, there’s a supplier here that fits your needs. And remember: choosing the right equipment isn’t just about today’s bottom line—it’s about building a future where e-waste is a resource, not a problem. So here’s to the suppliers, the recyclers, and everyone in between—thank you for keeping Singapore clean, one circuit board (and one ｄｒｏｐ of water) at a time.
