“…Another crucial strategy to enhance and optimize the production processes of 2G ethanol is the integration of techno-economic assessment (TEA) tools with novel approaches for pretreatment and hydrolysis of lignocellulosic biomass. These strategies can significantly contribute to the feasibility and efficiency of production processes, both in existing industrial operations and those in the implementation stage [25,26].…”

The replacement of fossil-based products with renewable alternatives is today a major research topic. Biofuels, such as second-generation ethanol, offer a promising way to overcome dependence on fossil fuels. However, second-generation biorefineries still face bottlenecks that hinder their economic sustainability. These include challenges in pretreatment (formation of inhibitors and high costs of chemicals) and hydrolysis (high enzyme costs and low solid content) and maximizing the utilization of biomass components. To achieve economic sustainability, biorefineries can adopt approaches such as integrating first and second generation (1G and 2G) technologies, using different production alternatives, or diversifying the product portfolio. This last alternative could include the simultaneous production of biomaterials, building blocks, and others from all fractions of the materials, favoring biorefinery profitability. Techno-economic assessment plays a crucial role in assessing the economic feasibility of these approaches and provides important information about the process. This article discusses how product diversification in cellulosic biorefineries enhances their economic sustainability, based on simulation techniques and techno-economic analysis, with a comprehensive and critical review of current possibilities and future trends. The information discussed can inform stakeholders about investing in 2G ethanol biorefineries, including strategies, associated risks, and profitability, allowing better planning of different options of future ventures.

“…It is important to clarify that this manuscript does not aim to provide an overview of the current state of the ethanol industry in terms of process economics and raw material usage. Numerous papers have already covered these aspects in detail, making it unnecessary to delve into them here (Mizik, 2021;Danelon et al, 2023;Gutierrez et al, 2023;Nimbalkar et al, 2023;Onu Olughu et al, 2023;Sica et al, 2023). Instead, the following section focuses on illustrating cases where the cost of a raw material transitions from being affordable to expensive when pursued for industrial applications, such as ethanol production.…”

The production of bioethanol is influenced by economic, social, political, and technological aspects. Technology has contributed to improving and simplifying the production process. On the other hand, the global pandemic of SARS-CoV-2, better known as Covid-19, has affected the market as its price has substantially increased. Raw material and transportation costs have also impacted the international market. Therefore, more efforts are being dedicated to finding alternative raw materials for bioethanol production. Agricultural waste or starches that are not used entirely for human consumption have the potential to produce bioethanol, but paradoxically, they cannot be commercialized. This report focuses on potential raw materials for bioethanol production and how their possible commercial exploitation declines when they acquire a cost for their transformation into higher value-added products. Price increases discourage investment in the diversification of these raw materials. DOI: https://doi.org/10.54167/tch.v17i3.1225

Myco degradation is an effective technique for breaking down waste plant substances made of lignin, cellulose, and hemicellulose, which are collectively known as lignocellulose. This abundant organic material is found throughout the world. Due to its recalcitrant nature, lignocellulose poses a challenge for efficient conversion into biofuels, biochemicals, and other valuable products. Myco degradation, which involves the use of fungi to degrade lignocellulosic materials, offers a sustainable and cost‐efficient resolution to this challenge. This review provides an overview of the mechanisms and applications of myco degradation for lignocellulosic biomass degradation. The review discusses the various types of fungi involved in lignocellulose degradation, their enzymatic systems, and the factors that influences their performance. Furthermore, the potential applications of myco degradation products, such as biofuels, enzymes, and bioplastics, are reviewed. It also highlights the implications of myco degradation for waste management and sustainable development. Overall, myco degradation represents a promising technology for the efficient deprivation of lignocellulosic waste biomass, and further research in this field holds great potential for the sustainable creation of bio‐based products.This article is protected by copyright.
