SESSION E13 / / 15:30 - 17:10
Chair / Presidente: W. Clarke (AU)
The concept of biorefinery has evolved over time from traditional bioferineries towards waste
biorefineries, with the environmental and economic sustainability as the main objectives.
Biorefinery schemes could consist of an anaerobic process performed in two stages, with the first one
managed in order to recover H 2 + CO 2 from fermentation, besides the CH 4 + CO 2 mixture produced in the second stage. Possible alternatives could include for instance the commercialization of the organic acids-rich solution produced in the fermentative hydrogenogenic stage, or its further and innovative valorization as readily biodegradable substrate for biopolymers production or to be fed to microbial electrochemical systems.
Despite the potential advantages, the following challenge still awaits environmental researchers and
practitioners: is the biorefinery concept feasible for waste management? and to what extent?
Discussion in the workshop will be preceded by the following technical presentations.
