“…1,2 First-generation biomass feedstocks are cultivated crops purposely for energy production, and in contrast, the issue of competition for food security arises. 14 Then comes the possibility of using second-generation raw materials from agricultural residues, 15 animals, [16][17][18][19] edible vegetables, 4,20,21 industrial 20,[22][23][24][25][26][27][28][29][30][31] and domestic. 10,32,33 And third and fourth-generation raw materials are microalgae.…”

“…In this process, triesters 1 with three long-chain carboxylic acids (C 8 -C 24 ) in the presence of methanol furnish fatty acid methyl (ethyl) esters 2 and glycerol (propane-1,2,3-triol) (3) as a side-chemical (Scheme 1). 22,25,39 According to the Organization for Economic Co-operation and Development (OECD) and the Food and Agriculture Organization (FAO), the world biodiesel production is expected to increase to 50 billion liters from 2021 to 2030, at a much slower pace during this period when compared to previous decades (Fig. 1).…”

“…This residue contains high levels of free fatty acids (FFAs) around 84% [3][4][5], in addition to tocopherols, squalene, and sterols [2]. Although many studies on the use of DDPO have focused on the synthesis of biodiesel [3][4][5][6][7][8][9][10][11], and biolubricant [12], as they make it possible to reduce the costs of production of renewable products, due to the use of low-grade raw material, it adds value to the residue and makes it possible to produce biodiesel and lubricant through a "clean" and environmentally compatible technology.…”

Increased consumption of palm oil results in more palm oil by-products. To meet environmental sustainability, deodorizing distillate palm oil (DDPO) also calls attention to diversifying its technological or commercial application. Because of this, the present work, to present new economic-scienti c alternatives for this by-product, aimed to evaluate the larvicide effect of DDPO, well as to investigate the synergistic effect of the combination of these fatty acid present in the composition of DDPO, against larvae of 3rd instar of Ae. aegypti. The DDPO larvicide assay showed a high mortality rate, with an LC 50 of 6.18 µg.mL − 1 at 24 h and 8.73 µg.mL − 1 at 48 h of treatment. In addition, the results of LC 50 , among saturated fatty foods and between the combination of fatty acid (myristic, lauric, stearic and oleic) with palmitic acid, were met positively by second-degree polynomial regression analysis. Finally, the study of molecular docking, corroborated, as potential inhibitors of the binding of juvenile hormones. Together, the results suggest that DDPO can be a potential natural larvicide agent, making it an alternative to the excessive use of synthetic insecticides, thus minimizing its impacts on the environment and promoting new technologies for the use of this palm oil by-product.

“…The production of renewable biofuels from vegetable oils and biomass residues has been shown to be an attractive alternative [1]. In the first generation of biofuels, some technologies involve the use of glucose in the production of bioethanol [2] and the use of vegetable oils and animal fats in the production of biodiesel by transesterification [3][4][5][6] or esterification [7,8]. The physical and chemical properties of these biofuels, however, limit their application as a drop-in fuel [9].…”

The pyrolysis of vegetable oil waste is an alternative way to convert biomass into high-quality second-generation biofuels, with social, economic and environmental sustainability. The present work deals with the pyrolysis of oleic acid as a model compound and an industrial vegetable oil residue on CuNiAl mixed oxide catalysts, derived from layered double hydroxides. Reactions of the oils pre-adsorbed on the catalysts (catalyst:oil mass ratio of 5:1) were performed at 550 °C on a micro-pyrolysis system and the analyses of volatile products were carried out online using GC/MS. Copper addition to NiAl catalysts increased the cracking of oleic acid. Increasing copper content also decreased the formation of aromatics and coke precursors, as well as oxygenated compounds. The CuNiAl catalyst with a Cu/Ni ratio of 0.4 showed strong catalytic activity in the conversion of an industrial vegetable oil residue with a high volume of free fatty acids produced. Compared to the non-catalytic reaction, the catalyst reduced the content of oxygenates and increased the content of hydrocarbons, particularly in the gasoline range (C5–C9). The CuNiAl oxide catalyst was able to convert vegetable oil residues into hydrocarbons in the range of gasoline, kerosene and diesel, and also linear alkylbenzenes as chemical precursors for surfactant production.
