The pursuit of renewable fuels for the transportation sector, particularly combustion engines like diesel, is crucial in reducing greenhouse gas emissions. This study introduces an innovative strategy biodiesel production utilizing marine macroalgae Ulva lactuca as primary feedstock, emphasizing sustainability and resource efficiency. Lipids were extracted from via a Soxhlet process characterized using GC–MS FTIR to ascertain fatty acid composition functional groups. Cu–BTC@AC catalyst, synthesized lipid-extracted algae residue pyrolysis hydrothermal treatment, underwent characterization SEM–EDS, XRD, techniques. Subsequently, catalyst was employed transesterification efficiently convert algal lipids into biodiesel, achieving high yield 92.56 % under RSM-optimized conditions: 65 °C temperature, 3.96 wt% amount, 15:1 methanol-to-lipid ratio, 140 min reaction time. Kinetic thermodynamic parameters calculated follows: Ea = 33.20 kJ mol−1, ΔH# 30.39 ΔS# –165.86 J mol−1 K−1, ΔG# 86.48 mol−1. analysis identified significant FAME content comprising 98.12 its composition. Notably, exhibited excellent reusability, maintaining 80.21 after third cycle. Moreover, physicochemical confirmed compliance with ASTM D6751 specifications, underscoring potential viable alternative fuel sector.
