Description

Stora Enso, a leading manufacturer of renewable products, is seeking approaches that enable the regeneration of periodate from iodate, consumed in one of their production processes.

Background

Currently, Stora Enso has a manufacturing process in place to produce one of their renewable materials. This process consumes large amounts of periodate, a very costly oxidizing agent. The entire reaction process is taking place in an aqueous solution and may contain, next to start, end and side products, other contaminants such as ions (calcium, magnesium, etc). In order to further scale and make the manufacturing process more economically viable, the recovery of periodate from iodate needs to be improved.
Hence, Stora Enso are seeking approaches that allow the efficient regeneration of periodate from iodate in aqueous reagents. Further, Stora Enso is open for collaborations with experts in the field to develop and test proposed concepts.
Stora Enso are keen to work with the selected solution providers to test, develop and prototype the methods.

Key success Criteria
  • Able to regenerate Periodate from Iodate
  • Can be done in an aqueous environment
  • Resistant to temperatures lower than 60°C

After development, the regeneration procedure should:

  • Be scalable 
  • Result in high re-oxidation yields
  • Avoid side reaction and side product formation
Possible Approaches
  • Electrochemical solutions
  • Alternative oxidation methods
  • Hypochlorite salts
  • Ozone
  • All other procedures that are not listed but meet the requirements
Approaches not of Interest

Environmentally harmful solutions
