It’s perfect for recyclers who want to dip their toes into wet processing without investing in a full-scale system.
A client in Woodlands, who switched to GreenTech’s wet process setup last year, noted: “We used to spend hours manually monitoring water quality. Now, the system has sensors that alert us if pH levels are off or filters need changing. It’s taken the guesswork out of compliance, and we’re recovering more gold and copper than before—so the ROI was faster than we expected.”
3. AquaRecycle Technologies
If water treatment is your top priority, AquaRecycle Technologies is the supplier for you. As the name suggests, they specialize in water management for recycling operations, and their circuit board recycling equipment is built around that core expertise. While other suppliers might treat water treatment as an “add-on,” AquaRecycle designs their recycling systems with water conservation and purification as the foundation.
What makes AquaRecycle unique is their focus on water reuse . In Singapore, where water is a precious resource, being able to recycle water within your facility isn’t just eco-friendly—it’s a competitive advantage. Their systems are engineered to treat wastewater so thoroughly that it can be reused in the recycling process, reducing your reliance on municipal water supplies and lowering your bills.
Standout Equipment:
Their flagship water process equipment line includes reverse osmosis units, ultrafiltration systems, and biological treatment reactors that break down organic contaminants. When paired with their circuit board recycling machines, which use low-flow water jets for precision cleaning, the result is a closed-loop system where water is used, treated, and reused with minimal loss. They also offer air pollution control system equipment to complement their water solutions, ensuring your facility meets both water and air quality standards.
One of their most popular packages is the “Zero-Discharge Circuit Board Recycling Suite,” which combines a medium-capacity shredder, dry separator, and advanced water treatment system. The suite is designed to discharge zero wastewater—all water is treated and reused. For recyclers aiming for green certifications or government grants for sustainability, this package is a no-brainer.
A large electronics manufacturer in Tuas, which uses AquaRecycle’s zero-discharge system to recycle its own production waste, shared: “We set a goal to be water-neutral by 2025, and AquaRecycle helped us get there two years early. The system not only handles our circuit board waste but also treats water from our other manufacturing processes. It’s been a win-win for our sustainability reports and our bottom line.”
4. CleanCircuit Equipment
CleanCircuit Equipment is for the recyclers who want to keep things simple—without sacrificing quality. They believe that effective recycling equipment shouldn’t require a team of engineers to operate, which is why their machines are designed with user-friendliness in mind.
