Nearly 90% of thermosets are produced from petroleum resources, they have remarkable mechanical characteristics, chemically durable, and dimensionally stable. However, can contribute to global warming, depletion reserves, environmental contamination during manufacture, use, disposal. Using renewable resources form thermosetting materials is one the most crucial aspects addressing aforementioned issues. Vanillin-based raw been used in industrial manufacturing polymer because simple modify structurally. Conversely, traditional as a broad class high-molecular-weight molecules challenging heal, decompose recover owing their permanent 3-D crosslinking network. Once products damaged, recycling issues could arise, causing resource loss impact. It be solved by inserting dynamic covalent adaptable networks (DCANs) into chains, increasing product longevity, minimizing waste. also improves attractiveness these prospective field. Moreover, it essential underline that lifespan reducing waste equivalent expense consuming resources. The detailed synthesis, reprocessing, thermal, characteristics partly entirely biomass polymers made vanillin-modified monomers covered current work. Finally, review highlights benefits, difficulties, application emerging vitrimers potential replacement for conventional non-recyclable thermosets.

Lignin, the earth’s second-most abundant biopolymer after cellulose, has long been relegated to low-value byproducts in pulp and paper industry. However, recent advancements valorization are transforming lignin into a sustainable versatile feedstock for producing high-value biofuels, bioplastics, specialty chemicals. This review explores conversion of lignin’s complex structure, composed syringyl (S), guaiacyl (G), p-hydroxyphenyl (H) units, value-added products. We critically assess various biochemical analytical techniques employed comprehensive characterization. Additionally, we explore strategies upgrading functionalization enhance its suitability advanced biomaterials. The emphasizes key areas valorization, including catalytic depolymerization methods, along with associated challenges advancements. discuss potential as diverse products such carbon fibers, adhesives, phenolic compounds. Furthermore, briefly inherent properties UV protectant antioxidant, alongside incorporation polymer blends composites. By presenting case studies from literature, this highlights significant economic environmental benefits waste reduction, lower greenhouse gas emissions, decreased reliance on non-renewable resources. Finally, address future perspectives achieving large-scale, techno-economically feasible, environmentally valorization.
