    Economic Analysis of Changes in Bioreactors Configuration Yielding Ethanol and Biochemicals
    (Springer Singapore, 2026) Arshia Akhtar, Haroon
    Economic analysis of changes in bioreactor configurations for ethanol and biochemical production involves evaluating the financial impact of modifications on reactor design, operation, and efficiency. By altering bioreactor configurations, such as introducing new mixing strategies, optimizing nutrient delivery, or improving temperature and pH control, the overall productivity of ethanol and other biochemicals can be increased, potentially lowering the cost of production. However, these changes often require capital investment in new equipment, technology upgrades, and possibly additional labor costs. From an economic perspective, the key benefits include enhanced yields, reduced processing times, and energy savings, all of which can contribute to cost reductions. For instance, more efficient bioreactor systems can minimize resource consumption (e.g., energy and raw materials) while maximizing output. On the other hand, the potential for increased operational complexity or the need for specialized skills in managing new configurations may increase maintenance and training costs. Ultimately, the economic viability of these changes depends on a careful cost-benefit analysis, considering both short-term investment and long-term returns. The balance between the initial outlay and ongoing operational savings determines whether the change will lead to overall profitability in ethanol or biochemical production. Continuous monitoring and optimization of the bioreactor's performance are essential to maximize economic returns.

    Bio-hydrogen production from lignocellulosic biomass: A Green Approach
    (Elite Publishing House, 2025) Arshia Akhtar, Haroon
    Bio-hydrogen (bio-H2), a carbon-low fuel known for its high energy efficiency, is gaining prominence as a renewable energy source amid increasing concerns about climate change and energy demand. Utilizing lignocellulosic biomass holds promise for establishing a clean energy infrastructure. Despite various technologies available for producing bio-H2 from lignocellulosic biomass, such as direct and indirect biophotolysis and fermentations, they suffer from drawbacks like low yields and slow production rates. Bio-H2, distinguishable among biofuels for its carbon neutrality, is achievable through thermochemical conversion methods, presenting an economically viable solution. While certain thermochemical conversion technologies are still in research and development, leveraging organic biomass for hydrogen production is strongly recommended due to its ability to yield larger quantities of the final product and its compatibility with existing infrastructure. This chapter aims to provide current insights into lignocellulose hydrogen conversion progress, tapping into its globally abundant availability.
