Exploiting cellulosic sewage and bacterial metabolism to produce novel bio-based compounds
REFRAME project aims to upgrade wastewater treatment plants into Water Resource Recovery Facilities in which wastewater and sewage sludge are used as raw materials for the production of different bio-based compounds. Wastewater contains important biomolecules whose recovery can support production of other compounds. Among these waste molecules is cellulose, the main constituent of toilet paper. With the support of the Marie Sklodowska-Curie Actions programme, the REFRAME project will develop a novel approach harnessing bacterial metabolism to valorise cellulosic primary sludge by recovering cellulose and converting it into compounds such as bio-based volatile fatty acids and polyhydroxyalkanoates for energy and feed for animals applications, respectively.
The new policies issued by the European Commission support the concept of bioeconomy and circular economy to develop a new value chain in the market across the implementation of innovative technologies for the production of bio-based compounds from (bio)waste and wastewater. In this scenario, REFRAME project aims to upgrade wastewater treatment plants (WWTP) into Water Resource Recovery Facilities (WRRF) in which wastewater and sewage sludge are used as raw materials for the production of different bio-based compounds. A bio-based compound is defined as a product that is derived from materials of biological origin. The main objective of REFRAME is to develop a new hybrid biological system assisted by an oxidation-reduction potential (ORP) based control for the combined production and purification processes of targeted bio-based volatile fatty acids (VFAs) and polyhydroxyalkanoates (PHAs). REFRAME will be the platform for chemicals, precursors for bioplastics, and feed ingredients ready for the market. A WWTP becomes a WRRF that attempts to produce valuable and marketable bio-based products, such as cellulose by utilizing the organic matter from the wastewater as raw material. The recovery of cellulosic primary sludge (CPS) could be biologically converted to other bio-based compounds, such as VFAs and PHAs. The project will advance the state of the art of the field by the investigation of a new type of bioprocess and bacterial metabolisms to fill the current lack of the long-term stability, quality, and purity of isolated bio-based compounds (VFAs and PHAs) produced from CPS as raw materials.
The applicant has a proven record of biological processes control, a fundamental skill required for REFRAME. He will thrive in the environment of the University of Verona, department of biotechnology. This project will enrich and broaden the applicants expertise in this field and fortify his international research career. |
