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

“The project is a collaboration between Chalmers, KTH, BillerudKorsnäs and TetraPak and will be 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.”
