In the trend toward green manufacturing and sustainable development, the electroplating industry is moving toward safe, environmentally friendly chemicals to improve plating quality, reduce pollution, and meet international standards.
Criteria for Choosing Safe and Environmentally Friendly Electroplating Chemicals
Free of hazardous metals (such as Cyanide, Cadmium, Cr6+…)
These compounds once delivered high performance but caused environmental pollution and serious health risks. Therefore, many leading companies are now choosing cyanide-free electroplating chemicals, such as Umicore’s electroplating product line, which provides excellent brightness, ensures user safety, and is environmentally friendly.

EU & QCVN-Compliant Air Filtration and Odor Treatment Systems
Electronic Waste Recovery for a Cleaner World
Electronic waste (WEEE) still contains valuable metals that can be recovered, refined, and reused. Besides causing severe environmental pollution, improper disposal also poses significant health risks.
Advanced thermal and chemical processing technologies have been developed to treat WEEE, recover precious metals, and extract rare earth elements. This enables the recovery of valuable raw materials while ensuring proper waste treatment.
A Green Chemistry Project for Lithium Recovery
Investment in advanced solutions for recycling lithium batteries used in electric vehicles, e-bikes, mobile phones, power tools, and many other everyday products.
Lithium is a critical material for modern technology, but global reserves are limited. Recovering lithium from spent batteries, together with cobalt, manganese, nickel, copper, aluminum, and lithium-based non-aqueous electrolytes, is essential for sustainable development.
Emission-Free Precious Metal Refining
The new EF-ZERO system from Italimpianti enables gold refining without air pollution. EF-ZERO plants refine gold alloys using aqua regia without releasing acid fumes while recovering nitric acid.
Key advantages include:
- Lower chemical consumption
- Shorter processing time
- Higher process efficiency, accepting gold alloys containing up to 20% silver
- Reduced labor for operation and monitoring
Wastewater and Exhaust Gas Treatment
A complete range of systems is available for neutralizing acid fumes from refining processes, extracting lead fumes from cupellation furnaces, and filtering fine and ultrafine dust using high-efficiency bag filters.
Additional solutions include:
- Filtration of neutralized solutions and recovery of copper oxide, zinc oxide, and other residues
- Treatment and recovery of wastewater and sludge from precious metal processing
- Treatment of nitrate-containing solutions
- Coagulation, flocculation, and sedimentation
- Demineralized water production for washing silver crystals from electrolytic and electrochemical refining
Dismantling and Refurbishment
Supporting the circular economy through equipment dismantling, refurbishment, overhaul, upgrades, and restoration of existing systems. Usable equipment is restored and returned to operation, while unusable components are collected and disposed of through certified channels. Support is also provided for equipment upgrades, obsolete component replacement, and production line expansion.
Green Factory
Sustainability starts from within. A photovoltaic system has been installed to generate 100% of the company’s electricity demand using rooftop solar panels, transforming the facility into a green factory. The old roof has also been replaced with aluminum-zinc roofing, providing a non-toxic, environmentally friendly, and more efficient solution.
