Natural luxury – Wooden crystals make fashion shine
Biomaterials and 3D-printing conjure a sparkle out of wood without harming people or the environment
Bioeconomy 2.0
Unseen bio-based materials. See this and other fascinating projects on display in the Designs for a Cooler Planet main exhibition in Marsio on 6 Sept – 3 Oct 2024.

Wood-derived lignocellulose is an abundant renewable raw material and the backbone of the Finnish economy. However, as our natural resources are declining, we must use them more wisely, creating more value from less raw material.
Bioeconomy 2.0 demonstrates how this challenge can become an opportunity in the right hands and through collaboration. These five novel, high-value applications of woody biomass aim to disrupt the status quo in materials, textiles and health technology, harnessing natural properties of lignocellulose to develop materials we have never seen before.
Projects on display
A hybrid material combining nanocellulose and a self-sterilizing pigment that kills aerosol pathogens when exposed to sunlight. It can be used for face masks or to sterilise surgical equipment in crisis areas lacking electricity.

Delving into the ecological concerns of modern fashion, the project addresses the environmental impact of traditional crystals, tainted by their origin in plastic and metallic effect pigments. This collaborative project, which includes The Structural Colour Studio and designer Anna Semi, redefines fashion sparkle with premium renewable materials. These crystals signify a step towards a more ecological and ethical future for fashion.
The “shimmering wood crystal” -concept explores nanocellulose-based, structural colour within the realm of fashion. The wood crystal is crafted by 3D printing a biodegradable wood filament pattern directly on a textile fabric (silk organza). This printed structure is then adorned with structural colour. The colour is entirely wood, does not fade like pigment or dye colours, and is fully biodegradable and non-toxic.
Wood-based glitter created through microscopically small structures from nanocellulose which can be used in design applications like clothing, architecture and furniture.
