“…TEA includes sensitivity analysis to assess the impact of uncertain parameters and variables on the economic performance of glucose production. This analysis explores how changes in factors such as raw material prices, energy costs, labor rates, and market conditions affect the profitability and overall economic feasibility of the process (Barba et al, 2022). Sensitivity analysis helps identify critical factors and assess the robustness of the project's financial performance under different scenarios.…”

This study explores and optimizes glucose production through various biochemical processes and assesses the potential of diverse feedstock sources to meet the growing demand for renewable carbohydrates. It focuses on glucose production's significance in biological systems and industrial applications, analyzing pathways like enzymatic hydrolysis of polysaccharides and acid hydrolysis of biomass. The kinetics of glucose production are examined, encompassing kinetic models for enzymatic hydrolysis, acid hydrolysis, and fermentation processes. Factors influencing reaction kinetics are explored, and experimental techniques for kinetic parameter estimation are discussed. To address sustainability and resource utilization challenges, the study investigates locally sourced materials like agricultural residues, forest biomass, algal biomass, and food waste as renewable feedstock sources. Optimization strategies for glucose production are presented, using statistical design of experiments and response surface methodology. Techno-economic analysis and life cycle assessments provide a holistic evaluation of environmental and economic aspects associated with glucose production processes. The study's comprehensive approach to glucose production, encompassing both technological advancements and sustainability considerations, offers insights into enzymatic, acid hydrolysis, and fermentation processes, as well as comparing diverse feedstock sources. This knowledge can foster further advancements in the field, benefit industries, and encourage policymakers to promote the integration of renewable carbohydrates in the broader bioeconomy. The research contributes to the global shift towards a greener and more sustainable future, where glucose production plays a key role in building a resilient and eco-conscious society.

“…However, the main economic aspect of the enzymatic treatment of pollutants is the cost of the enzyme [103]. A recent study evaluated the costs of applying enzymes for hydrolyses of a municipal solid waste-derived pulp and described enzyme costs in the range of GBP 1-4/Kg [104]. Another study evaluated the techno-economic analysis of the production of enzymes such as Laccase from pumpkin peels as a substrate [105].…”

Pharmaceutical residues are of environmental concern since they are found in several environmental compartments, including surface, ground and waste waters. However, the effect of pharmaceuticals on ecosystems is still under investigation. To date, the removal of these micropollutants by conventional treatment plants is generally ineffective, in addition to producing a considerable carbon footprint. In this sense, to achieve the current zero-pollution ambition, a reduction in the negative impacts of chemical substances such as pharmaceuticals on the environment must be aligned with initiatives such as the European Ecological Compact, Environment Action Programme, and Circular Economy Action Plan, among others. This review provides insight into the key drivers for changing approaches, technologies, and governance of water in Europe (Germany, Switzerland, and the UK), including improving wastewater treatment in sewage treatment plants for the removal of pharmaceuticals and their carbon footprint. In addition, an overview of emerging low-carbon technologies (e.g., constructed wetlands, anaerobic membrane bioreactors, and enzymes) for the removal of pharmaceuticals in sewage treatment works is provided. In general, the removal efficiency of pharmaceuticals could be achieved up to ca. 100% in wastewater, with the exception of highly recalcitrant pharmaceuticals such as carbamazepine (removal <60%). These technologies have the potential to help reduce the carbon footprint of wastewater treatment, which can therefore contribute to the achievement of the Europe Union’s objective of being carbon neutral by 2050.

“…Enzymatic hydrolysis does not leave residual toxic chemicals; therefore, it is preferred in food processing [4]. A potential drawback is the high cost of enzymes [18]. Nevertheless, enzymatic hydrolysis is a reasonable alternative for recovering proteins and creating products with potential applications in various areas [2].…”

As global fish consumption rises, a large amount of waste is generated that is generally neglected. Considering the value embedded in these resources, sustainable methods become more important in extracting valuable ingredients from fish processing residues. Enzymatic hydrolysis is a fast and easily reproducible method for recovering protein ingredients and obtaining valuable by-products. To confirm its advantages, an environmental and economic impact assessment is essential. This study overviewed the sustainability and economic viability of extracting protein compounds and oil from Atlantic mackerel processing residues using enzymatic hydrolysis. Life cycle assessment (LCA) and life cycle cost analysis (LCCA) methods were employed. It was found that the climate change impact of the whole process was 0.073 kg CO2-eq per 1 g of fish protein hydrolysate (FPH). As the process produces FPH as the main product and fish oil as the by-product, economic allocation was used to distribute the impacts of FPH and fish oil. The findings of the LCCA showed that producing 1 g of FPH costs EUR 3.68. The contribution analysis indicated the crucial role of electricity and fish in environmental impacts. To ensure the accuracy of the calculation, the results of an LCA study published previously were recalculated. The sensitivity analysis showed that the results were susceptible to the region and source of electricity production. This research provides valuable insights into the sustainability and economic aspects of using enzymatic hydrolysis for extracting protein ingredients and oils from Atlantic mackerel. This can inform future investigations of environmentally friendly and economically viable solutions for extracting fish ingredients.
