Abstract
The main goal of this Research Project is to establish the fundamental bases to apply the biorefinery concept to a biological wastewater treatment plant, with generation of bioenergy and high value-added products. Such conception is based on the use of anaerobic reactors as the core technology in a wastewater treatment plant, mainly because this process generates a broad spectrum of organic acids and solvents in the liquid phase besides hydrogen and methane in the biogas. In this new approach, the wastewater treatment plant, with their reactors and unit operations, is a network of facilities to produce biofuels, power, and chemicals from organic wastewater. Several challenges must be overcome with this approach, including the low concentrations of organic matter in wastewater, leading to low concentration of intermediates and end products, and the complex composition of wastewater, with spatial and temporal variations. The use of mixed microbial cultures, though important and beneficial for anaerobic process, is another drawback for the biorefinery concept, since process control tends to be difficult. In this context, a multidisciplinary research group was formed to establish the scientific and technological fundaments of a biorefinery fed with wastewater aiming at the generation of profitable products and energy besides complying with its main function of mitigating impacts from the release of wastewater into the environment.
