The Centre of Expertise Biobased Economy is organising a webinar on natural colourants for bioplastics on 20 April. Specifically, it will focus on turmeric.

Synthetic dyes for plastics are often toxic and poorly degradable. Even if they were applied in biobased or biodegradable plastics, harmful substances would remain behind, reducing the amount of waste plastics that can be recycled or composted.

The Interreg Northwest Europe project CurCol aims to change this by investigating the production and application of natural turmeric-based colourants in bioplastics and paper packaging. The project and its results will be highlighted during the webinar.
