Society is becoming increasingly aware of the environmental impact of our consumption behaviour, such as the increasing amount of plastic packaging waste. Limburg SMEs EGGXPERT, colorFabb, Helian Polymers and CHILL aim to achieve the transition from a linear to a circular economy using a natural polymer PHA and calcium-based minerals (ESP) from eggshell waste streams. The project aims to change the 3D printing industry by creating eco-friendly and personalized unique products. By using PHA and ESP, the focus is on a shift away from petrochemical-based plastics to innovative, natural and biodegradable alternatives. These new materials strengthen the circular economy, by using local waste streams and by biodegradability at end-of-life .
