Headquartered in Tokyo, the company has pioneered closed-loop water treatment in circuit board recycling, ensuring zero wastewater discharge in many of its models.

Star Product Line: Their flagship WCBD-2000A Circuit Board Recycling Plant is a game-changer. Equipped with both dry and wet separation modules, it processes 500–2000 kg/hour of PCBs while integrating a multi-stage water treatment system. The plant uses ultrafiltration and activated carbon adsorption to purify water used in metal recovery, reducing freshwater consumption by up to 70% compared to conventional systems.

Eco-Focus: Mitsui’s air pollution control system complements its water treatment, capturing 99.9% of particulate matter and volatile organic compounds (VOCs). Clients in Germany and South Korea praise its ability to meet EU’s strict emission limits without sacrificing speed.

Global Impact: Installations span 32 countries, with recent projects in India and Brazil focusing on sustainable urban mining. “Mitsui’s after-sales team stayed with us for 6 months to fine-tune the water system,” notes a plant manager in Singapore. “We now recycle 10 tons/day with water costs cut by half.”

Niche Expertise: Toshiba Eco Solutions has carved a niche in dry process equipment with integrated water-saving features—a boon for regions with water scarcity. Their PCB recycling systems prioritize minimal water use without compromising metal recovery rates.

Innovative Design: The Compact Granulator with Dry Separator eliminates the need for water in initial PCB shredding and separation. For plants requiring wet processing, their optional water process equipment uses reverse osmosis to recycle 95% of water, making it ideal for arid regions like the Middle East and Australia.

Client Success: A recent project in Dubai saw Toshiba’s dry-wet hybrid system process 800 kg/hour of PCBs, achieving 98% copper recovery and 92% gold recovery—all while using just 500 liters of water per ton of feedstock. “We were skeptical about dry processing,” admits the facility’s engineer, “but Toshiba’s system matched wet methods in purity, and our water bills plummeted.”

Sustainability Credentials: ISO 14001 certified, Toshiba also offers carbon footprint audits for clients, helping them qualify for green energy incentives.

Engineering Prowess: A subsidiary of the industrial giant Hitachi, Zosen Inova specializes in large-scale recycling plants. Their PCB systems are known for rugged durability and seamless integration of hydraulic press machines for metal compaction, paired with advanced water treatment for high-volume operations.

Flagship System: The WCB-2000C Circuit Board Recycling Plant is built for heavy-duty use, processing 2000 kg/hour with a wet separation module. Its water treatment line includes pH neutralization, sedimentation tanks, and UV disinfection, ensuring water meets Japan’s strict effluent standards (BOD < 10 mg/L, SS < 30 mg/L). The plant’s hydraulic press then compacts metal residues into briquettes, reducing transport costs by 40%.

Global Footprint: Zosen Inova dominates the European market, with installations in Germany, France, and Poland. Their systems are tailored to comply with EU’s Waste Electrical and Electronic Equipment (WEEE) Directive, including extended producer responsibility (EPR) tracking software.

Testimonial: “We run 24/7, and the Zosen Inova plant hasn’t skipped a beat in three years,” says a UK-based recycler. “The water treatment is low-maintenance—our operators only check filters weekly, and the system alerts us remotely if there’s an issue.”

Focus on Precision: Komatsu, a name synonymous with engineering excellence, brings its manufacturing rigor to PCB recycling. Their systems are celebrated for pinpoint metal separation and energy-efficient water treatment, making them a favorite among high-end electronics recyclers.

Key Innovation: The Dry Process Equipment with Integrated Water Reclaim Unit is a standout. While primarily a dry system (using air classification and electrostatic separation), it includes a small-scale water treatment module for cleaning fine metal particles. This hybrid approach cuts water usage to just 100 liters per ton of PCBs—perfect for facilities prioritizing sustainability without dry-only limitations.

Support & Service: Komatsu’s global service network ensures quick access to parts and technical support. Their Tokyo-based R&D team also offers custom water treatment upgrades for existing plants, a service that has won them clients in Taiwan and Malaysia.

Circular Economy Champion: Panasonic’s eco-division takes a holistic approach, designing PCB recycling systems that align with the company’s “Zero Waste” 2050 goal. Their water treatment systems are modular, allowing plants to start small and expand as needed.

Notable Product: The Compact Granulator with Dry Separator is ideal for mid-sized operations (300–800 kg/hour). Its water treatment add-on uses membrane bioreactors (MBRs) to treat process water, producing water clean enough for reuse in cooling systems. Panasonic also offers training programs for operators to optimize water and energy use.

Local Impact: In Japan, their systems power municipal e-waste recycling centers, processing over 10,000 tons of PCBs annually with minimal environmental footprint.

Heavy-Duty Reliability: Sumitomo’s PCB recycling lines are built for industrial-scale operations, with a focus on reducing downtime. Their water process equipment is designed to handle high solids loads, a common challenge in PCB recycling where resins and plastics can clog systems.

Technology Edge: Their 2000kg/hour Circuit Board Recycling Plant uses a unique inclined plate sedimentation system to separate metal-rich sludge from water, increasing treatment efficiency by 30%. Paired with a hydraulic press machine for sludge dewatering, the plant reduces waste volume by 85%.

Global Projects: Sumitomo recently delivered a turnkey plant to Saudi Arabia, where its water treatment system was adapted to handle high-salinity local water, ensuring consistent performance in harsh conditions.

Automation Leaders: Yaskawa combines robotics and AI with PCB recycling, creating systems that minimize human error and maximize water treatment efficiency. Their “Smart Recycling” platform uses sensors to adjust water flow and chemical dosages in real time.

AI-Driven Water Treatment: Their WCBD-300A Plant (300–500 kg/hour) features AI-controlled pH and turbidity sensors that optimize coagulant and flocculant use in water treatment, reducing chemical costs by up to 25%. The system also predicts maintenance needs, alerting operators before filters or membranes fail.

Client Love: “The AI takes the guesswork out of water treatment,” says a recycler in Canada. “We used to overuse chemicals to stay compliant—now Yaskawa’s system keeps levels perfect, and our costs are down.”

Material Science Experts: Kobe Steel leverages its metallurgy expertise to design PCB recycling systems that maximize metal recovery while protecting water resources. Their wet process equipment is particularly effective for extracting precious metals like gold and palladium.

Water Treatment Innovation: Kobe’s Solvent Extraction Water Purification System uses selective solvents to recover metals from water, reducing the need for chemical precipitation. This not only cuts sludge production but also allows for higher metal purity in outputs.
