Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

TECHNOLOGY OVERVIEW

The use of bioplastics has grown rapidly in recent years as consumers and businesses become more aware of the environmental benefits of these materials. However, there are still some challenges that are inherent to bioplastics such as high costs in comparison to fossil-based plastics and that not all bioplastics are derived from bio-based sources, biodegradable or compostable. These materials also face processing limitations and lower mechanical properties which often results in the combination of fossil-based polymers being added to improve these properties. This technology aims to address these factors to increase the adoption of bioplastics in more applications.

The technology is a new bioplastic material that is fully bio-based and compostable. Based on a reactive processing technology combining polyhydroxyalkanoates (PHAs) with other biopolymers and bio-based polymers, the resultant blend provides unique properties such as biodegradability (soil or water) and compostability (industrial and home). The material blends can be designed for processing using standard plastic processing technologies and modified for a wide range of mechanical properties.

The technology owner is interested in co-development opportunities with Singapore plastic processing companies looking to develop new applications with bioplastics.
