Scale-up of sustainable production of dialdehyde cellulose and dialcohol cellulose

Treesearch research themes:

Project partners:



The project is a collaboration between Chalmers, KTH, BillerudKorsnäs and TetraPak. 

The aim of the project is to develop a closed or semi-closed techno-economical feasible process for production of Dialdehyde cellulose, DAC and its derivatives with a target to replace plastic materials in different applications such as thermoforming, extrusion and moulding. 

The project will have focus on;

• The recovery and reuse of process chemicals in the process where periodate is used to oxidise cellulose to DAC. 

• Isolation, fractionation and identification (size and carbohydrate content) of products in the process water, especially partly modified oligocelluloses and hemicelluloses. 

• An efficient and techno-economical feasible process for the reduction step of DAC to dialcohol cellulose.

This is a Treesearch Postdoc project.
