“…The idea of a biorefinery is comparable to oil-based refineries, which produce a variety of chemical compounds that can be upgraded into a wide range of end-products. A biorefinery utilizes the majority of biomass elements to add value to the raw materials treated [23]. Two factors allow us to differentiate between oil refineries and biorefineries.…”

“…However, the implementation of these biorefineries did not have the expected feasibility results. Thus, a fixed strategy for the proper design of these systems must be defined [23,104]. The strategy can be based on an improved conceptual design [28].…”

“…When raw materials are integrated into a biorefinery, it is possible to maximize the value generated by using the fractions of the components of the heterogeneous raw material. Additionally, several costs within the process are reduced such as the costs associated with duplicating the equipment (if raw materials are taken independently) and, in turn, reduces energy costs and helps the demand for energy in a more efficient way than a single raw material biorefinery [23].…”

“…This aspect is key for developing small-scale processes since the economic feasibility of a process with multiple raw materials is not highly affected by the price change. Thus, multifeedstock biorefineries can be used as a potential strategy for boosting rural bioeconomies in developing countries where large amounts of biomass are not valorized [23]. If there are biorefineries based on a single raw material, fluctuations in the price or even in the acquisition of the raw material will force the owners of the process to redesign it, reduce scales, and may even stop production, such as the case of a company in the United States where they obtained biodiesel during the years 2005 to 2008 [105].…”

Biorefineries have been defined as complex systems where biomass is integrally processed to obtain value-added products and energy vectors, involving recent research advances, technological trends, and sustainable practices. These facilities are evolving since new pathways and challenges for biomass upgrading appear constantly aimed at increasing process sustainability. Nevertheless, few literature papers summarize how these new trends can improve biorefinery sustainability and boost the transition to renewable resources. This paper reviews several challenges and future perspectives before biorefinery implementation at the industrial level. Challenges related to waste stream valorization, multifeedstock use, biorefinery energy matrix diversification, and new products based on new biomass conversion pathways are reviewed. Thus, this paper provides an overview of the most recent trends and perspectives for improving biorefinery sustainability based on waste stream minimization, integral use of raw materials, and high-value bio-based compound production. A case study is discussed to show how integral biomass upgrading can improve the economic and environmental performance of existing processing facilities. Carbon dioxide capture, storage, and conversion, as well as energy matrix diversification, have been identified as the most important aspects of improving the environmental performance of biorefineries (decarbonization). Moreover, multifeedstock biorefineries are profiled as promising options for upgrading several biomass sources in small-scale and modular systems to produce value-added products for boosting rural bioeconomies. Finally, new ways to produce more bio-based products must be proposed to replace existing oil-based ones.

“…Integration into a distributed manufacturing network. Recent approaches in biorefining enable the synergistic coupling of systems like the one introduced in this paper with a network of biomass suppliers, decentralized infrastructures, and product distribution through a distributed manufacturing platform [25,47].…”

Solar-Assisted Monetization of Municipal Solid Waste

2023

View full text Add to dashboard Cite

Municipal solid waste (MSW) is a significant resource, especially for biomass-based monetization. In addition to its economic potential, it can also provide an effective pathway for decarbonization in the energy and chemical sectors. In this work, MSW monetization is coupled with the solar-assisted generation of “green” hydrogen and oxygen via electrolysis. The dual utilization of electrolysis-produced hydrogen and oxygen offers several advantages, including the reduction in the carbon footprint, the tunability of the characteristics of synthesis gas (syngas) to conform to the values needed for the manufacture of various chemicals, and the reduction in the overall cost compared to systems focusing on hydrogen generation only. A superstructure is developed to represent the configurations of interest and serve as a basis for formulating an optimization program that can be solved to identify the optimal design and operating strategies. A multi-period optimization formulation is developed to identify the maximum profit subject to the various modeling equations and constraints. The environmental considerations are addressed using the ɛ-constraint method by iteratively varying carbon footprint cuts. A case study is solved for the City of Jeddah, and the results assess the tradeoffs of various design and operating strategies, their impact on profitability, and their environmental impact.
