Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

open access: yesBiofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1948-1969, November/December 2025.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental
