Abstract
The NordiCoats project aims to develop innovative bio-based epoxy compounds tailored for high-performance applications, with a focus on sustainability and environmental responsibility. By integrating biotechnological and chemo-synthetic strategies, the project aims to reduce dependence on fossil-derived resources and promote recyclable, safer alternatives in the epoxy industry.
A key focus of NordiCoats is the utilization of alginate—a linear biopolymer composed of β‐D‐Mannuronic acid and α‐L‐Guluronic acid—known for its versatility in industrial and medical applications [1]. In addition to being found in algae, alginate can be efficiently produced through microbial fermentation [2]. In this project, side streams from brewery and aquaculture have been used as feedstock for the microbial alginate production. By fine-tuning production parameters and perform chemical or enzymatic modifications in the downstream processing, alginates can be engineered to meet the requirements needed for epoxy formulations. This approach not only supports a circular economy but also enhances the sustainability and scalability of bio-based epoxy manufacturing. Through these innovations, NordiCoats addresses critical environmental and health challenges associated with conventional epoxy compounds, contributing to a more sustainable future for the coatings industry.
