Assessing the potential of non-edible oils and residual fat to be used as a feedstock source in the enzymatic ethanolysis reaction

- The potential of six non-edible feedstocks were assessed to yield biodiesel by enzymatic route.
- Lipase from Burkholderia cepacia immobilized on silica-PVA was used as biocatalyst.
- All feedstocks were found to be suitable for biodiesel production, attaining yields higher than 94.6%.
- The high yields obtained enable the product to be classified as a fuel according to ASTM standards.
