The NiCo Process
What is NiCo?
NiCo is short for Nickel Containment – an innovative process that keeps the resource nickel completely within the process cycle.
This drastically reduces the ecological footprint of zinc phosphating and sets a new standard in sustainability.
​
Three good reasons for NiCo
1. Ecology & Sustainability
-
Over 90% of nickel is lost in conventional processes.
-
NiCo keeps the nickel completely in the cycle – no discharge into wastewater, no hazardous sludge.
-
Thus, NiCo actively protects the environment and resources.
2. Economy
-
Nickel will be one of the critical raw materials from 2030 onwards.
-
Global demand is rising sharply, while new sources of supply are hardly in sight.
-
NiCo reduces chemical consumption and operating costs – both sustainably and economically.
3. Occupational Safety
-
Nickel is classified as carcinogenic, especially in wastewater treatment.
-
NiCo completely avoids contact with nickel residues – for maximum safety in operation.
Technological Basis
The process begins immediately after the active zinc phosphating bath. The rinse water is treated, divided, and recirculated.
The result: fewer chemicals, lower costs, maximum resource efficiency.
Advantages of the NiCo Process
Savings in chemicals and costs in zinc phosphating
Minimization of heavy metal load in wastewater
Improved environmental footprint and increased operational safety
In a nutshell:
NiCo makes sustainability measurable – no loss, no risk, only progress.
