Hybrid ELectrosynthesis of Value-Added chemicals - HELVA

Project summary

Rationale: the manufacturing of chemicals and carbon-based materials still relies on fossil fuels and energy/carbon-intensive processes. HELVA proposes an alternative approach using CO2 as the carbon source to realize complex carbon-based non-petrochemical plastics powered by renewable electricity. Objectives: HELVA pursues the e-synthesis of polyhydrohyalkanoates (PHAs) from captured CO2 using a tandem system approach that couples CO2 electrolysis and microbial bio-upgrade. We will pursue these goals through advances in catalyst, system, and reactor design, as well as microbe engineering to promote PHA metabolic pathways. Our final objective is the synthesis of PHA at concentrations above 50 g/L. Potential applications: The realization of sustainable biodegradable plastics. Impact and potential benefits: The proposed technology would offer a path for the sustainable biological manufacturing of non-petrochemical renewable plastics, mitigating global emissions and warming.
