VOLATILE – Biowaste derived volatile fatty acid platform for biopolymers, bioactive compounds and chemical building blocks.


December 1st, 2016 – November 30th, 2020


Worldwide, there is a growing appreciation that the management and utilization of natural resources needs to be improved. The demand on natural resources has been growing fast and exceeds what the Earth can sustain in the long term. Developing a sustainable circular economy that uses eco-efficient processes and renewable raw materials is one key strategic challenge for the 21st century. Approximately 20-40% of all municipal solid waste streams are biowaste, resulting in almost 90 million tonne/year in  Europe, making this an ideal resource for the bioeconomy.

The VOLATILE project aims in the development of an innovative process for the biological conversion of municipal solid biowaste and WWTP sludge to volatile fatty acids, capable to be integrated into existing anaerobic digestion plants. The produced volatile fatty acids (VFAs) will be used as carbon source for the fermentative production of biopolymer PHA (material application or feed additive), single cell oil from yeasts (chemical building blocks in the oleochemical industry) and long chain high unsaturated omega-3 fatty acids from heterotrophic microalgae (bioactive compound for food and nutraceutical industry).
