The proposed project aims at validating and establishing a sustainable process for bioplastics production through use of microalgae, in the framework of a biorefinery approach which includes: wastewater treatment and complete valorization of the produced microalgal biomass towards biodegradable polymers, polyhydroxyalkanoates (PHAs), natural pigments and bioenergy, in the form of biogas.

Plastic‐derived pollution has been recognized as a major, global concern that necessitates immediate action to be taken25 million tons plastic per year accumulate in the environment, while in 2014 5.25 trillion plastic particles weighing 269.000 tons were estimated to be floating in the sea, representing up to 95% of marine pollution in some areas. To this end, alternative solutions such as production of biodegradable polymers of biological origin, that will replace conventional plastics, are necessary.
In the framework of ALGAPLAS Project, several microalgal species, including unexplored eukaryotic strains, will be investigated for PHA production during cultivation in digestates to improve the economic feasibility and environmental sustainability of the technology.
