B-Plas Sbrl

B-Plas is an innovative start-up and benefit corporation, that has developed a new process focused on the recovery of valuable materials from wastewaters.

The B-Plas process minimizes the volumes of sludge to be disposed of, with significant savings on disposal costs, and furthermore converts a significant fraction of the soluble organic carbon (COD equivalent) into PHA (polyhydroxyalkanoates), a renewable, biodegradable and compostable bioplastic.

The B-PLAS process is modular and flexible. It includes a mechanical pre-treatments then an hydrothermal carbonization, which solubilizes part of the carbon and converts the residual solid into hydrochar; then an anaerobic biodigestion transforms the soluble carbon into volatile fatty acids. The suspension is separated with a filter press, to give highly dehydrated sludge and nutrient-rich waters which are fed to an anoxic aerobic digester, which converts the organic carbon into a PHA-rich biomass.

Finally, the PHA is extracted from the biomass and destined to B2B market.

B-Plas designs and installs a plant as add-on to the existing wastewater treatment plant, fully customized to the specific application, thanks to a deep laboratory testing and engineering of each single step of the process.
