Ethanol from stillage goes commercial in Sweden using Indonesian fungi

Ethanol with a production of close to 90 billion liters is the largest product of biotechnology in term of the volumes. Ethanol concentration is generally around 10-11% that goes to distillations and ethanol is separated from the slurry named "stillage".  It means we have close to 900 million m3 of stillage per year in the world. The stillage contains about 10% solid materials.

We have worked several years to produce ethanol and animal feed from this stillage. We used an edible fungus that is originated from Indonesia in a food named "oncom". In has been developed in our lab and examined in large scale at the ethanol plant Agroetanol. They are now planning to use it commercially. It is exciting for both the company and also our research group that developed the process. This news was published in the Swedish newspaper NyTeknik a few days ago.
