Tanning Water Recovery
Zero-waste leather production.
Tanning wastewater doesn’t have to be a burden.
Our BIOS SOBA system recovers chrome, salts, enzymes, and clean water directly from tanning processes — turning one of the most resource-intensive industries into a circular one.
We make tanneries more efficient
The problem.
Why is tanning wastewater so challenging?
High chrome and salt loads
Variable pH between process steps
Large volumes of wastewater
High disposal cost and regulatory pressure
Risk of pollution incidents
Growing sustainability expectations from brands

Tanning Water Recovery
Why it matters.
Leather tanning is resource-intensive
Leather tanning is resource-intensive: large volumes of water, chemicals, and energy go into every batch of hides.
Yet most of that value is lost — discharged as wastewater and sludge.
With BIOS SOBA, tanneries can reclaim that value.
By recovering chrome, salts, enzymes, and water across core tanning processes, the system reduces chemical purchases, lowers wastewater disposal cost, and helps brands meet their sustainability commitments.
Circular tanning is no longer a concept — it’s an operational reality.

Our BIOS SOBA tanning recovery process
Every tannery is different — but our recovery strategy follows a clear, proven path.
1. Assess & Map
We analyze each wastewater stream (soaking, liming, deliming, pickling, chrome tanning) to map recovery potential.
2. Pilot on site
A pilot unit validates chrome, salt, enzyme, and water recovery on real production streams.
3. Deploy
Full-scale recovery modules are installed and integrated into your existing tannery operations.
4. Optimize
Sensors and digital monitoring ensure stable performance and consistent product quality.
Proof of performance
Long-term industrial operation with stable recovery of chrome, salts, enzymes, and water.
Suitable for tanneries
Built for the pH swings, variability, and heavy loads specific to modern tanneries.
Every tannery is unique.
