Photo by courtesy of Naser Tavajohi (edited by A.S.). is part of a new multi-partner project to create a biorefinery for organic waste—with end products such as bio-based plastics, animal feed, “green” chemicals, biofuels and higher alcohols (Fusel oil)—in a two-step process.
If successful, the result could become a trendsetter concept for how to create a virtually waste-free system of making the said commodities, but as bio-based alternatives to their current fossil resource-based counterparts.
Researchers at the University of Borås in Sweden gave birth to the idea that the concept of biogas making could be expanded to deliver much more than just biogas car fuel, which is produced from the fermentation of food and agricultural waste in an oxygen-free environment.
In addition to this kind of bacterial break down of organic residues (anaerobic digestion), they want to add two more main processes to reuse all of the contents of the organic waste feedstock. These processes are referred to as 'membrane reactors' and 'biological augmentation', in scientific speak.
Although Tavajohi could not give an exact figure on the envisioned capacity, the scale would be near or at the level of industrial implementation. Consultants from RISE Research Institutes of Sweden were set to assist the academic researchers in some part of the project, he told Bio4Energy Communications in an online interview.
