13. Crude glycerin combined with food additives in feeding beef cattle
ABSTRACT The objective of this study was to evaluate the effects of adding crude glycerin with food additives (sodium monensin or essential oils) to the diets of beef cattle on feed intake, ruminal parameters, in vitro digestibility, and production of greenhouse gases. Five ruminally cannulated Nellore steers were randomly assigned in a 5×5 Latin square des

14. Crude glycerin in co-composting with laying hen manure reduces N losses
ABSTRACT: The composting of laying hen manure is an efficient way of treating waste and producing an organic fertilizer with excellent characteristics; however, the high N losses reduce its concentration in the resulting fertilizer. Associating this residue with crude glycerin (CG) promotes a better C:N ratio and contributes to higher N retention during comp

15. Performance and carcass characteristics of goats fed crude glycerin in the feedlot and during pre-slaughter lairage
ABSTRACT This study evaluated the effects of crude glycerin (CG) supplied separately from the other dietary ingredients to goats during the feedlot and in the pre-slaughter lairage on the nutrient intake, performance, behavioral and physiological parameters, carcass characteristics, and meat quality. Twenty-eight uncastrated male goats from a cross between t

16. Estudio de la cinética de la disolución de los barros residuales de las industrias borateras con soluciones de glicerina
ABSTRACT In this paper the dissolution kinetics of industrial boron wastes residual with glycerin solutions (C3H8O3), effluent from the biodiesel industry, with the aim of enhancing the utilization both wastes, were investigated. It is based on the complexation of boron with the polyol. The dissolution is carried out in a batch reactor at atmospheric pressur

18. Performance and carcass characteristics of lambs fed a solution of crude glycerin during feedlot and pre-slaughter lairage
ABSTRACT The objective of this study was to evaluate performance and carcass and meat characteristics of lambs fed a solution of crude glycerin plus water (100 g kg−1 of dry matter) (GLY) during feedlot and pre-slaughter lairage. Data were analyzed as a 2 × 2 factorial (GLY available or not in feedlot and GLY available or not in the slaughterhouse). We ev

19. Development and clinical efficacy evaluation of anti-greasy green tea tonner on facial skin
ABSTRACT Green tea (Camellia sinensis (L.) Kuntze, Theaceae) polyphenols have activities against skin disorders; however, anti-sebum efficacy of green tea cosmetic has sparely been reported. The facial tonner containing green tea was therefore developed and clinical evaluated. The base formulas which stabled following accelerated tests were sensorial assesse

21. Evaluation of Lubricating Properties of Diesel Based Fuels Micro Emulsified With Glycerin
The mineral diesel oil sold in Brazil, due to environmental reasons; presents sulfur concentration of 10 ppm, which causes a deficiency of lubricity, since sulfur is one of the chemical species that gives a good lubricating characteristic. Poor lubricity affects performance and causes failure of engine parts. This study aimed to evaluate the use of glycerin

22. Green polyurethane synthesis by emulsion technique: a magnetic composite for oil spill removal
Abstract After the consolidation of the Brazilian biodiesel industry, issues related to the final destination of the glycerin, the by-product from the biodiesel industrial process, drawing the attention of several researchers. There are several uses to this byproduct. Among them, the obtaining of polymers, such as polyurethane (PU), are very encouraged since

23. The use of crude glycerin as an alternative to reduce fermentation losses and enhance the nutritional value of Piatã grass silage
ABSTRACT The objective of this study was to evaluate fermentation losses and the nutritional value of silage of Brachiaria brizantha cv BRS Piatã ensiled with different levels of crude glycerin. The experiment followed a 4 × 2 completely randomized factorial design with four doses of crude glycerin (0, 100, 200, and 300 g kg–1 of DM silage) and two cutti
