Special Issue Information

Dear Colleagues,

Lignocellulosic biomass, including agricultural and forestry residues, municipal waste, and by-products from agro-food processing, offers an abundant, renewable carbon source for biofuel and bioproduct production. When processed within a biorefinery, this diverse biomass can be fractionated to generate multiple products, thereby significantly improving process economics. Such an integrated approach not only increases profitability, but also advances sustainable production by optimizing resource use and minimizing waste, contributing to a circular bioeconomy.

This Special Issue invites original research articles that explore integrated biorefinery approaches designed to utilize multiple components of lignocellulosic biomass for the production of biofuels, biochemicals, and high-value bioproducts to maximize the value extracted from raw materials. We seek studies that provide experimental insights into biomass conversion techniques, including, but not limited to, thermal–chemical, biochemical, and catalytic processes for refining biomass fractions into diversified product portfolios. Additionally, we encourage sustainability-oriented research that conducts techno-economic analysis (TEA) and life cycle assessment (LCA) to evaluate the economic and environmental impacts of integrated biorefinery systems.

Polyurethane (PU) is widely used due to its attractive properties, but the shift to a low-carbon economy necessitates alternative, renewable feedstocks for its production. This review examines the synthesis, properties, and sustainability of bio-based PU materials, focusing on renewable resources such as lignin, vegetable oils, and polysaccharides. It discusses recent advances in bio-based polyols, their incorporation into PU formulations, and the use of bio-fillers like chitin and nanocellulose to improve mechanical, thermal, and biocompatibility properties. Despite promising material performance, challenges related to large-scale production, economic feasibility, and recycling technologies are highlighted. The paper also reviews life cycle assessment (LCA) studies, revealing the complex and context-dependent environmental benefits of bio-based PU materials. These studies indicate that while bio-based PU materials generally reduce greenhouse gas emissions and non-renewable energy use, their environmental performance varies depending on feedstock and formulation. The paper identifies key areas for future research, including improving biorefinery processes, optimizing crosslinker performance, and advancing recycling methods to unlock the full environmental and economic potential of bio-based PU in commercial applications.
