Techno-Economic Analysis of Succinic Acid Production from Sugar-Rich Wastewater

Succinic acid (SA) is a valuable platform chemical that can be converted into biodegradable plastics, resins, solvents, etc. The emerging biological routes for SA production are gaining more attention because they exploit the natural abilities of bacteria to fixate carbon dioxide (CO2). On other hand, an inexpensive organic source fulfill energetic requirements microbial strain also significant challenge industrial production. current work presents holistic techno-economic analysis using sugar-rich residual streams and biogas as raw materials. Simulation results showed by establishing integrated process, high simultaneously achieved with upgrading. CO2 provided from carbohydrates, which by-products two products: biomethane (CH4 > 95%, clean biofuel), SA. mass energy balances indicators were simulated calculated SuperPro Designer®. total capital investment cost facility producing 1000 tSA/year estimated EUR 5,211,000 2,339,000 per year, respectively. revenue was 2,811,000 while due produced, namely, 198,150 Nm3 corresponded 205,284 year. return on investment, payback period, internal rate project found 11.68%, 8.56 years, 11.11%,
