WHAT DRIVES US
Wasting our waste
Humanity knows how to recycle – at least when it comes to solids.
Instead of collecting valuable materials from liquid waste, we are throwing them away.
What a waste.
WHAT MAKES US DIFFERENT
Next generation water treatment
We believe there is hidden, untapped value in industrial water processes. With right solutions wastewater could be utilized as an important source of raw materials.
We aim to act as pioneers of a closed material cycle – by providing solutions that enable raw material recovery.
Our history
Our story began from a cutting-edge research that led to the invention of 4D Scavenger®. Weeefiner was founded to drive the technology forward and to this day, it has already been applied for dozens of elements and various fields including mining, metallurgy, and process industries.
