Integrative technical, economic, and environmental sustainability analysis for the development process of biomass-derived 2,5-furandicarboxylic acid

H. Kim et al.

Summary: This study presents a new process design for economically producing FDCA from lignocellulosic biomass. The process maximizes the economics by introducing effective biomass fractionation method and minimizing energy consumption. The economic feasibility and environmental sustainability of the process were assessed through techno-economic analysis and life-cycle assessment.

Assessing the Economic Viability of the Plastic Biorefinery Concept and Its Contribution to a More Circular Plastic Sector

Megan Roux et al.

Summary: This study aimed to investigate the transition from fossil-based to renewable plastics by upcycling PET into PEF and PTT. A techno-economic analysis revealed that increased recycling rates could reduce the minimum selling price (MSP) of second generation bio-plastics, showing a beneficial effect on the economic viability of upcycled plastics.

Techno-economic analysis and life cycle assessment of a biorefinery utilizing reductive catalytic fractionation

Andrew W. Bartling et al.

Summary: Reductive catalytic fractionation (RCF) is a promising method to fractionate lignocellulose and convert lignin to a narrow product slate. Analyses of techno-economic, life cycle assessment, and air emissions are crucial for guiding research towards commercialization, with a focus on cost and sustainability considerations.

The green platform molecule gamma-valerolactone - ecotoxicity, biodegradability, solvent properties, and potential applications

Florian Kerkel et al.

Summary: This paper presents toxicity and biodegradability data of GVL, as well as a detailed study on harmful solvents that could potentially be replaced by GVL and further applications of this substance based on HSP and COSMO-RS calculations. The results indicate low acute toxicity of GVL towards aquatic organisms and its potential as a green solvent. GVL was found to be similar to several highly dipolar solvents and could be of interest in various industries such as manufacturing, cleaning, and cosmetics.

Production of HMF, FDCA and their derived products: a review of life cycle assessment (LCA) and techno-economic analysis (TEA) studies

Matthew G. Davidson et al.

Summary: Research suggests that bio-based production of HMF and FDCA may reduce CO2 emissions compared to fossil-based products, but it can also increase environmental impacts in other categories, with expensive feedstocks and high energy demands making it less economically viable. Further investigation into different raw materials, energy production methods, and catalytic systems may help improve the production of HMF and FDCA.

From sugars to FDCA: a techno-economic assessment using a design concept based on solvent selection and carbon dioxide emissions

Amir Al Ghatta et al.

Summary: The production of 2,5-furandicarboxylic acid (FDCA) from sugars for the replacement of PET by PEF faces challenges related to the stability and isolation of the precursor HMF. Different solvents have varying impacts on cost, emissions, and commercial viability. A two-step, one-pot reaction is shown to be an economically and environmentally feasible solution, making FDCA competitive with terephthalic acid. Further research is needed to optimize the process and reduce emissions.
