There is an increasing demand for sustainable solutions to quench our thirst for oil-derived carbon compounds. Anaerobic treatment provides the means to efficiently produce renewable chemicals from organic residues. The recent discovery of controllable isobutyrate production during mixed culture fermentation opens the possibility to develop new biorecovery technologies.
Isobutyrate is a platform chemical that can be used for a wide range of products, including: flavors, fragrances, animal feed additives, emulsifiers and organic solvents. Classical synthesis of isobutyrate uses fossil fuels and involves hazardous polluting chemicals. The new technology will help to close the carbon cycle and contribute to a healthier environment.
