Energy-efficient production of pressboard and algae-based materials

By combining advanced laboratory experiments with numerical modelling, the project aims to unravel how water is removed from dense mats under hot-pressing conditions and to use that knowledge to optimise the process. We will build a physics-based simulation model that mimics the real press-and-dry process and validate it against experimental data. 

The 30-month project is a collaboration between KTH (coordinating university) and two industry partners: Hitachi Energy and Nordic Seafarm. KTH contributes expertise in the processing of biobased materials, in-situ experiments, and process modelling, whereas Hitachi Energy and Nordic Seafarm provide industrial context, process data, samples and co-funding (covering half of the project cost through cash and in-kind).

The work is structured into experimental research – processing of samples in lab setups using advanced tools like X-ray/neutron imaging to observe internal dewatering phenomena – and model development.

The expected outcomes are a validated computational model and a prototype digital twin system that industry can utilise to improve their manufacturing processes, leading to more energy-efficient and sustainable manufacturing of cellulose-based insulation materials, in line with the call’s goals for a sustainable and competitive bioeconomy.
