| Popis: | Oily waste from sanitation processes was characterized for its potential use in the generation of biofuels. The waste residues studied showed high levels of oil and grease, reaching up to 87% (m/m) in a grease trap of a food company, showing that these residues can be utilized for the production of biofuels. The results revealed high levels of moisture and saponification as well as high levels of free fatty acids (FFA). Analysis of chromatographic profiles (HPLC) showed great heterogeneity of the fatty acids contained in the sample, and a predominance of palmitic, oleic, linoleic and linolenic acids. |
