SYNTHESIS AND PROPERTIES STUDIES OF SUSTAINABLE MATERIAL DERIVATIVES FROM 5-HYDROXYMETHYLFURFURAL
Biomass fuels are essential for sustainability, maintaining a balanced carbon cycle by releasing carbon dioxide during combustion equivalent to what was absorbed during growth. This results in lower net greenhouse gas emissions compared to fossil fuels and aligns with green chemistry principles, promoting the use of renewable feedstocks and fostering a circular economy. Cellulosic biomass, derived from renewable sources and processed through sustainable practices, plays a significant role in coatings, materials, textiles, and biofuel production. 

The conversion of cellulose into 5-hydroxymethylfurfural (HMF) represents a key advancement in sustainable chemistry. HMF serves as a renewable precursor for bio-based chemicals and fuels, offering alternatives to petrochemical products and reducing reliance on fossil fuels. This presentation examines the synthesis and application of HMF derivatives, including biobased thiols and thioesters, oligomers, and both non-segmented and segmented polyurethanes, contributing to a more sustainable chemical sector.
