Every year, millions of tons of electronic waste end up in landfills, and printed circuit boards (PCBs) are among the most challenging—and valuable—components to recycle. Packed with gold, silver, copper, and hazardous materials like lead, PCBs demand specialized equipment to recover resources safely. While dry processes have long been common, water-based (wet process) PCB recycling equipment is gaining traction for its ability to separate metals with precision, reduce dust pollution, and handle delicate components without damaging valuable materials. In 2025, these suppliers are leading the charge in making wet process PCB recycling efficient, scalable, and eco-friendly. Let’s explore the top players reshaping how we turn e-waste into reusable resources.

1. WasteCycle Tech – The Heavyweight of High-Capacity Wet Processing
Founded in 2005 and based in Germany, WasteCycle Tech has built its reputation on machines that handle industrial-scale e-waste. Their flagship product, the 2000kg/hour circuit board recycling plant WCB-2000C with wet separator , is a beast in the field. Designed for large recycling facilities, this system can process up to 2 tons of PCBs per hour—perfect for cities or regions drowning in e-waste.
What Makes It Stand Out?
The WCB-2000C combines shredding, grinding, and water-based separation in one seamless line. Here’s how it works: First, PCBs are shredded into small particles. Then, a series of wet separators use water density to separate metals (like copper and gold) from non-metals (plastics and resins). The magic? Its proprietary “turbulent flow” separation chamber, which adjusts water pressure in real time to catch even tiny gold flakes—something many dry processes miss.
Customers rave about its reliability. “We’ve run 12-hour shifts for months, and the only maintenance needed is basic cleaning,” says Maria Gonzalez, operations manager at a Spanish e-waste plant. “The wet process also cut our dust complaints from neighbors by 90%.”
WasteCycle doesn’t stop at PCBs, either. They offer water process equipment for other e-waste streams, making them a one-stop shop for facilities looking to expand their recycling capabilities.
2. EcoRecycle Solutions – Smaller Facilities, Big Results
Not every recycler needs a 2-ton-per-hour monster. EcoRecycle Solutions, based in Canada, specializes in mid-sized systems that pack power without the massive footprint. Their star product, the circuit board recycling plant with dry separator 500-2000kg/hour capacity (yes, they offer wet variants too!), is a hit with regional recyclers who need flexibility.
Why Mid-Sized Recyclers Love Them
EcoRecycle’s wet process line uses a “modular” design—you can start with a 500kg/hour setup and add modules later to hit 2000kg/hour as your business grows. The wet separator uses a gentle agitation method that preserves fragile components, like surface-mount chips, which often get crushed in harsher dry systems. “We recover 15% more gold from smartphone PCBs with their wet process,” says Raj Patel, owner of a U.S.-based e-waste startup. “That extra yield pays for the machine in under a year.”
They also prioritize user-friendliness. The control panel is designed with touchscreen interfaces and automated cleaning cycles, so even staff with minimal technical training can operate it. “No more hiring expensive engineers just to keep the machine running,” Patel adds.
3. GreenWaste Innovations – Eco-Friendly to the Core
For recyclers who put sustainability front and center, GreenWaste Innovations (U.S.-based) is a top choice. Their wet process equipment is engineered to minimize water usage—a critical factor in drought-prone regions. How? They’ve developed a closed-loop water system that recycles 95% of the water used in separation, with only a small amount lost to evaporation.
Water Conservation Meets Efficiency
“We were skeptical at first—how do you cut water use and still get clean separations?” admits John Lee, sustainability director at a California recycling co-op. “But GreenWaste’s system uses filtration layers that trap metal particles while letting water circulate back. We now use 10,000 gallons less per month than with our old dry system.”
Their PCB recycling line also integrates air pollution control system s to capture any fumes from soldering residues, ensuring compliance with strict environmental regulations. “The EPA did an audit last year and couldn’t find a single violation,” Lee says. “That peace of mind is priceless.”
4. CircuitCycle Systems – Precision Engineering from Japan
Japanese engineering is synonymous with precision, and CircuitCycle Systems lives up to that reputation. Their wet process equipment is designed for recyclers who need to separate ultra-fine metals, like the tiny gold wires in semiconductor chips.
Micro-Separation Technology That Wows
CircuitCycle’s “nano-separator” uses ultrasonic waves to agitate water, creating microscopic bubbles that attach to metal particles as small as 5 microns. This allows them to recover metals that often slip through standard wet or dry processes. “We process old computer motherboards, and the nano-separator pulls out gold dust we didn’t even know was there,” says Takashi Mori, a Tokyo-based recycler. “Our profit margin jumped 22% after installing it.”
Of course, this precision comes with a higher price tag, but Mori insists it’s worth it. “When you’re dealing with precious metals, even a 1% increase in recovery adds up fast.”
5. AquaRecover Tech – Emerging Markets’ Best Friend
Based in India, AquaRecover Tech understands the unique challenges of recycling in emerging markets: limited infrastructure, inconsistent power, and budget constraints. Their water process equipment is built tough, with simple mechanics that can handle voltage fluctuations and dusty environments.
Durability That Thrives Off the Grid
“We have areas where power cuts happen daily,” says Amara Okafor, who runs a recycling center in Nigeria. “AquaRecover’s machine has a battery backup for the control system, so even if the main power goes out, we don’t lose our processing data. And the parts are easy to source locally—no waiting 3 months for a replacement from Europe.”
Their entry-level wet separator starts at under $50,000, making it accessible to small businesses. “We started with one machine, trained 3 staff, and now we’re processing 300kg of PCBs weekly,” Okafor adds. “It’s changed our community—we’re creating jobs and cleaning up e-waste dumps that used to poison our soil.”
6. CleanE-Waste Machinery – Europe’s Compliance Experts
Europe has some of the strictest environmental laws in the world, and CleanE-Waste Machinery (based in the Netherlands) builds machines that don’t just meet regulations—they exceed them. Their wet process equipment is certified to comply with EU’s WEEE Directive, REACH, and RoHS, making them a favorite among European recyclers.
Compliance Without Compromise
What sets them apart? Their water treatment system. The wastewater from PCB processing is treated on-site, removing heavy metals and chemicals before it’s released or recycled. “Our local environmental agency did surprise tests, and the water leaving our plant was cleaner than the tap water in my office,” jokes Pieter Janssen, owner of a Dutch recycling firm. “They even asked if we could help treat their municipal water!”
CleanE-Waste also offers training programs to ensure staff know how to maintain compliance. “They sent a trainer for a week to walk our team through every step of the process,” Janssen says. “No other supplier offers that level of support.”
7. ResourceMax Engineering – Heavy-Duty Shredders Meet Wet Separation
Before PCBs can be separated, they need to be shredded into manageable pieces. ResourceMax Engineering, based in Australia, combines shredder and pre-chopper equipment with wet separation in a single integrated line—saving recyclers time and floor space.
From Shred to Separate in One Flow
“We used to have a separate shredder and separator from different suppliers, and coordinating maintenance was a nightmare,” says Liam Walsh, operations director at an Australian e-waste facility. “ResourceMax’s all-in-one line has cut our downtime by 40%. The shredder even adjusts its speed based on the separator’s needs—if the separator is processing slowly, the shredder slows down to avoid jams.”
Their shredders are built for tough PCBs, including those with thick metal frames or ceramic components. “We’ve thrown everything at it—old military PCBs, server motherboards, even damaged circuit boards with solder balls—and it chews through them without hesitation,” Walsh adds. “The wet separator then takes over, and we’re left with clean metal concentrates ready for smelting.”
8. PCB Reclaimers Inc. – North America’s Trusted Workhorse
With over 30 years in the industry, PCB Reclaimers Inc. (U.S.-based) has a loyal customer base that swears by their reliable wet process systems. Their focus is on “no-frills” equipment that works day in and day out, with minimal fuss.
Simplicity = Reliability
“We don’t need fancy bells and whistles—we need a machine that starts when we press ‘on’ and runs until we press ‘off’,” says Mike Thompson, a third-generation recycler in Michigan. “PCB Reclaimers’ wet separator is exactly that. We’ve had ours for 7 years, and the only part we’ve replaced is a pump—after 50,000 hours of operation!”
They also offer lifetime technical support, a rarity in the industry. “I called at 2 a.m. once because we had a clog, and a technician walked me through fixing it over the phone,” Thompson recalls. “You don’t get that with overseas suppliers.”
9. HydroCycle Equipment – Innovating for Lithium-Ion and PCBs
As lithium-ion battery recycling booms, HydroCycle Equipment (South Korea) is bridging the gap between battery and PCB recycling. Their wet process systems can handle both lithium battery components and PCBs, making them ideal for facilities looking to diversify.
Dual-Purpose Design Saves Space and Money
“We used to have separate lines for batteries and PCBs, but HydroCycle’s system lets us switch between them with a quick change of separator screens,” says Kim Ji-hyun, a Seoul-based recycler. “The wet process works equally well for separating copper from PCB resins and lithium from battery cathodes. It’s like having two machines in one.”
They’ve also developed a water process equipment add-on that neutralizes battery acids before separation, preventing corrosion and improving metal purity. “Our copper recovery from batteries went from to 99.2% after adding the neutralization step,” Kim adds. “That’s a huge difference when selling to smelters.”
10. PureCycle Technologies – The New Kid with Big Ideas
Founded in 2018, PureCycle Technologies (Singapore) is the youngest supplier on this list, but they’re making waves with cutting-edge automation. Their wet process systems use AI to optimize separation, learning from each batch of PCBs to improve efficiency over time.
AI-Powered Recycling for the Future
“The AI analyzes the composition of incoming PCBs—how much copper, plastic, gold is present—and adjusts the water flow, temperature, and agitation speed accordingly,” explains Dr. Tan Wei, PureCycle’s chief technology officer. “A batch of old TV PCBs needs different settings than smartphone PCBs, and the system figures that out on its own. Our customers see a 15-20% increase in separation efficiency within the first month as the AI learns.”
Early adopters are impressed. “We process mixed PCBs, and some days it’s 60% plastic, others 80% metal,” says Alex Chen, a recycler in Malaysia. “PureCycle’s AI keeps the yields consistent, even when the input is all over the place. It’s like having a PhD in materials science running the machine 24/7.”
Choosing the Right Supplier for Your Needs
Selecting a water-based PCB recycling equipment supplier isn’t just about buying a machine—it’s about partnering with a company that understands your goals, whether that’s high capacity, sustainability, or flexibility. Here’s what to keep in mind:
- Capacity: Match the machine to your current volume, but leave room to grow (modular systems like EcoRecycle’s are great for this).
- Compliance: If you’re in Europe or North America, prioritize suppliers like CleanE-Waste with strict environmental certifications.
- Support: Look for lifetime technical support and local service centers to avoid long downtime.
- Versatility: If you plan to recycle other e-waste (like batteries or cables), consider dual-purpose systems from HydroCycle or WasteCycle.
Water-based PCB recycling is more than a trend—it’s a smarter, cleaner way to turn e-waste into resources. With these suppliers leading the charge, 2025 is shaping up to be the year wet process technology becomes the gold standard in e-waste recycling. Whether you’re a small startup or a global facility, there’s a system out there that fits your vision for a greener future.
