Materials in general —metals, polymers, and ceramics— are essential to the advancements in contemporary global society. Despite this, it is evident that the sustainability of the world and global ecosystems are threatened by their short life cycle and poor circularity. We are therefore developing materials that facilitate the shift from a linear to a circular economy. In order to achieve this, we base our work on the following principles: renewability (utilising natural resources like cellulose or chitin), reuse (increasing the useful life) and recycling (primary, secondary, and tertiary recycling of polymers). We also research how materials (bio)degrade and how it affects the environment and public health.

• Chitin-based pulps: Structure-property relationships and environmental sustainability

• Cellulose-based ionic conductor: an emerging material toward sustainable devices

• Prospects for the integration of lignin materials into the circular economy

• 3D printing to enable the reuse of marine plastic waste with reduced environmental impacts
