Abstract:
Severely degraded lands can contribute to bioeconomy growth through the cultivation of specific oleaginous plants. According to EU Directive 2018/2001, known as RED2, severely degraded land means land that, for a significant period, has either been significantly salinated or presented significantly low organic matter content and has been severely erode. Additionally, the future development of biorefineries should leverage opportunities from the expansion of green hydrogen production through process and local/territorial integration. Numerous bio-based processes utilize hydrogen as a reducing agent to produce drop-in biofuels, biojet fuels, and biochemicals. By combining bioresource availability from dedicated crops in severely degraded land with variable renewable energy sources producing green hydrogen on-site, an optimal biorefinery-based system can be developed to produce biofuels, biochemicals, biomaterials, and achieve negative CO2 emissions. This study introduces a novel biorefinery concept focused on a specific territory rich in marginal lands, where the potential for various types of bioresources can be assessed. Carbon atoms from vegetable oils, residual lignocellulosic biomass can be converted into target products through biorefinery processes, such as hydrogenation. Carbon dioxide generated from biorefinery processes can be captured and converted through hydrogenation with in-situ green hydrogen, making the overall process carbon-negative. Additionally, this work presents an analysis of the optimal biorefinery processes and scales from a techno-economic-environmental perspective.
