Value from wastewaters

Added-value products including chemicals, energy and fuels

​Industrial wastewater constitutes a complex and diverse mixture of compounds challenging to process. When disposed to the environment, the great value is lost and nature is polluted. Exploit the potential of your wastewaters with our help, and you can save the unnecessary operational costs and get added-value from your wastewaters.



VTT's analytics experts (link to analytics) can identify the contaminants contained in your wastewater. Depending on the type and concentration of contaminants in the wastewater, we will select the most adequate treatment techniques.  Added-value chemicals may be additionally produced to improve the economy of your process. The value of your wastewaters will increase after reducing the environmental impact and disposal costs.



We have developed research facilities for aqueous-phase reforming (APR). Our expertice covers catalytic APR of all the way from cleaner mixture of compounds to various wastewater streams. With our test reactor we can develope and optimize your wastewater treatment processes and help you to get added-value from wastewaters.

Besides APR, our research interests are in filtration, membranes and catalytic membrane development. We can modify membranes of different materials to express catalytic activity and altered hydrophilicity and pore size. Currently, we are trying to resolve lignin originated fouling problem.

VTT brings value to wastewater by...

  • Catalyst development
  • Product upgrading
  • Process integration

We can be your R&D partner in developing membrane technologies, filtration processes and getting valuable products from process streams and wastewaters. 

Challenge: Process water streams with contaminants such organic compounds are challenging and costly to process.

Solution: Wastewater processing to decrease the concentration of contamiants and produce added-value compounds.

Benefit: Wastewater disposal cost decrease and potentieal for process product inegration
