VIVALDI’s objectives

These are the main goals of VIVALDI project, which guide the activities of 9 interlinked work packages.

Develop, upscale and validate a reliable methodology for the conversion of raw CO2 emissions to MeOH and FA at biocompatible conditions to serve as microbial feedstock.

Develop and validate an integrated, efficient yeast-based fermentation process for the conversion of CO2, MeOH and FA into added-value organic acids (3-HP, IA, LA, SA) using Pichia Pastoris yeast strain as microbial chassis.

Advance the circularity of bio-based industries by developing a new (bio)electrochemical process to recover the nutrients necessary for the fermentation from industrial wastewater.

Design and validation of downstream processes with high efficiency (in terms of yield, chemical usage and energy demand) and in compliance with the end-users specifications.

Demonstrate the technical and economic feasibility of integrating the VIVALDI concept (or, at least, part of it) in existing bio-based industries.

Ensure the positive impact of VIVALDI’s solutions from an environmental, economic and social point of view, and  facilitate their replicability in other bio-based industries and industrial sectors.

Identify market opportunities and regulation bottlenecks for the market adoption of VIVALDI solutions and products.

Raise awareness on the role of the CO2-based industry in climate change mitigation, and disseminate the knowledge generated from VIVALDI project.


VIVALDI aims to upgrade the current Technology Readiness Level (TRL) of the proposed technologies up to 5, thereby, validating them at litre-scale with real emissions/effluents in a relevant industrial environment.

The adoption of the VIVALDI concept allows the transform of current biorefineries into plants with negative GHG emissions and sets the path towards the implementation of a new CO2-based industrial sector that is environmentally and economically competitive with the current fossil-based alternatives.
