Efficient Nickel Recovery for Cost Savings and Sustainability
El desafío
An international automotive parts manufacturer sought to recover valuable materials, cut operational costs, and minimize waste discharge. The manufacturer faced pressure to meet strict local discharge limits for nickel (Ni <100ppm) while recycling materials typically sent for disposal. Achieving compliance while reducing costs was a top priority.
Key figures:
Annual Nickel Sulfate consumption: 48,000 kg.
Annual cost: 1,536,000 RMB.
La solución MacDermid Envio
MacDermid Envio identified the manufacturer as an ideal candidate for the NiCycle Nickel Recovery System. The system, equipped with advanced automation and continuous recovery capabilities, was installed to recover nickel as Nickel Sulfate, which was reused directly in electroplating processes.
Resultados
The NiCycle system delivered outstanding outcomes:
- Recovered 90% of Nickel from rinse water, yielding up to 43,000 kg of NiSO4 annually
- Achieved annual savings of 1.3M RMB
- Reduced nickel waste concentration to below 100ppm, meeting discharge limits
- Significantly lowered waste treatment costs through nickel recycling
This solution provided the manufacturer with a sustainable, cost-effective approach to nickel recovery and waste management.
