Introduction
There has never been a more pressing global need to shift away from an economy reliant on fossil fuels and toward a sustainable, bio-based future. Innovative approaches to energy, materials, and products are required due to climate change, resource depletion, and environmental degradation (Sulis et al. 2025). Leading this shift is lignocellulosic biomass, the planet’s most plentiful renewable organic resource that provides a carbon-neutral substitute for petrochemicals (Arhin et al. 2023). These plant-derived materials, which include cellulose, hemicellulose, and lignin, are becoming more and more acknowledged for their potential in the production of advanced biomaterials, biofuels, and biochemicals (Singhvi et al. 2019).
Notwithstanding its enormous potential, there are many obstacles in the way of lignocellulosic solutions’ broad acceptance and commercialisation. The current rate of development, the changing focus of industrial and research endeavours, and the enduring obstacles preventing the complete adoption of environmentally conscious, sustainable lignocellulosic technologies are all examined in this editorial. The goal is to give a succinct summary of the advancements that have been made and the crucial areas that need focused attention in order to hasten the development of a strong lignocellulosic bioeconomy.
Pace, Direction, and Barriers to Implementation
Innovation in lignocellulosic valorisation has advanced at an impressive rate thanks to developments in materials science, chemical engineering, and biotechnology. Research is now focused on second-generation biorefineries that use non-food biomass sources such as agricultural residues and specialised energy crops, rather than first-generation biofuels, which frequently have competed with food crops (Makepa et al. 2024). By enabling precise modifications to improve bioenergy traits, boost resilience to environmental stresses, and increase biomass yield, emerging biotechnologies such as CRISPR-based genome editing are revolutionising feedstock engineering (Sulis et al. 2025). By guiding next-generation mutagenesis and breeding techniques for lignocellulose feedstocks, machine learning models are speeding up this process even more (Sulis et al. 2025).
Integrated biorefinery concepts are becoming a more prominent focus of lignocellulosic research and development. By generating several co-products (biofuels, biochemicals, and biomaterials) as opposed to a single output, these systems seek to optimise the value extraction from biomass (Makepa et al. 2024). This multi-product strategy improves resource efficiency and economic viability. For example, nanocellulose applications in energy storage and biomedical scaffolds are currently being investigated for cellulose, which has historically been used for paper and textiles. Platform chemicals are being created from hemicelluloses, which are frequently broken down during conventional pulping. Value-added chemicals and biopolymers are giving lignin, the most resistant component, new life (Sulis et al. 2025). The changing uses of lignocellulosic components are compiled in Table 1.

Despite these developments, there are still major implementation hurdles that prevent lignocellulosic solutions from being widely used in commerce. These obstacles have many different aspects, including socio-political, technical, economic, and regulatory aspects. The interrelated difficulties in the lignocellulosic biorefinery innovation chain are depicted in Fig. 1.
