VIVALDI turns co2 emissions into sustainable bioproducts

VIVALDI project will develop an innovative, sustainable and cost-efficient biotechnological solution to convert off-gas emissions from bio-based Industries into CO2-based chemicals. In this way, the industry’s greenhouse gases emissions will not only be reduced, but will be used as a novel feedstock, lowering the dependency on fossil fuels import and the exploitation of key resources such as energy, raw material, freshwater and land.

Project Concept

VIVALDI project will develop an integrated solution to convert the CO2 emissions of bio-industries into 4 added-value organic acids: lactic acid (LA), succinic acid (SA), itaconic acid (IA) and 3-hydroxypropionic.

These acids can re-enter in the production process of biorefineries to enhance their sustainability, or become building blocks for novel biomaterials.

Project Impact

Contributing to the transition to a low carbon economy and reach European climate targets

Negative to neutral CO2 emissions in the production of organic acids
-20% cost & energy demand for the production of organic acids compared to fossil-based industries

-25% cost for ammonia recovery from industrial wastewater

Such organic acids are lactic acid (LA), succinic acid (SA), itaconic acid (IA) and 3-hydroxypropionic. Organic acids are important for the chemical industry as they are the building blocks for the production of chemicals including biobased products.
