Abstract:
The outbreak and rapid spread of the COVID-19 pandemic has hit the global financial markets, including the energy and materials sector. Biomass belongs to the economy’s key sectors concerning environmental issues and seems to be a mature alternative for fossil-based conventional energy and materials. The post-COVID-19 zero-waste circular economy is transitioning to sustainable consumption and production. The main goal of this study is the value-added products development, within the industrial ecology concept, investigating the potential use of torrefied wheat straw for the removal pollution, like Methylene Blue (MB) a basic dye, from water and wastewater. The experimental adsorption kinetics were simulated using three kinetic models: (i) Lagergren model, (ii) second order model, and (iii) intraparticle diffusion model, thus revealing that the adsorption of MB onto torrefied wheat straw is best simulated by the second-order kinetic model. Therefore, torrefied wheat straw, a well-known renewable energy source for coal substitution, could be also an activated carbon low-cost alternative, within the biorefinery and the zero-waste circular economy concept.
