A new project called COM4PHA is developing bioplastics based on Polyhydroxyalkanoates (PHAs). These materials offer a biodegradable alternative to conventional plastics currently in use. PHAs are produced by various microorganisms and share characteristics with petrochemical plastics.
This research focuses on finding cheaper alternative substrates for production. Agro-industrial waste and industrial by-products are being explored for this purpose, as well as improved extraction strategies. The goal is to reduce overall product costs. This aims to facilitate their incorporation into the market, which is currently dominated by petroleum-based plastics.
The COM4PHA project is developing new bioplastic formulations based on the PHAs group. The project seeks to promote new product development lines which will utilize these biodegradable materials effectively. Specifically, the project uses the PHBV copolymer. This is for applications in both packaging and agriculture.
Innovative processing technologies are being employed for this polymer type. These technologies include hollow-body blown extrusion used for creating bottles. The copolymer is also applied as a coating. This is being tested on paper substrates and agricultural mulch films.
Optimizing the material’s synthesis is another project objective. Favoring the scaling up of larger quantities is essential, as this will enable offering PHBV at an industrial level. It aims to reach certain applications presently occupied by conventional materials.
Biotech company Venvirotech is coordinating this project. They specialize in transforming organic waste and their tech uses bacteria to produce PHA bioplastics. ENPLAST, which specializes in creating plastic packaging, is also participating. They will be responsible for validating the developed materials. AIMPLAS, the Plastics Technology Centre, acts as a link. AIMPLAS is in charge of the new PHA formulations. This includes formulations for both packaging and coatings.
New formulations for cosmetic packaging are being developed. These are designed to be biodegradable and compostable, and will comply with established requirements. This is expected to reduce their environmental impact and may also lead to better product acceptance by the market.
