Physico-Chemical Characterization of Oily Sanitary Waste and of Oils and Greases Extracted for Conversion Into Biofuels.

Abstract: INTO BIOFUELS. 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 th… Show more

“…The largest fraction of TS was represented by TVS, indicating a high biodegradable fraction of this residue. This result was compatible with that of Oliveira et al [7], who performed chemical physical characterization of oily residues from sanitation waste and observed that the largest fraction of total solids was represented by volatile solids. Cucina et al [11], when evaluating the risks and benefits associated with the agricultural use of three different organic fertilizers derived from a pharmaceutical manufacturing effluent, found values of 14.30% and 8.80% for total solids and volatile solids, respectively.…”

“…Laboreaux, in the city of Itabira, Minas Gerais, Brazil, showed that pressurized filtered sludge, if subjected to drying to improve heat output, can be used as a fuel to supply consumers in the region, replacing coal or firewood [6]. Another study characterized the physicochemical properties of oily residues from sanitation, and only from this study was it proposed that the use of these residues may serve as a substrate for the production of biofuels [7].…”

“…As a result, residual triacylglycerides can be an alternative raw material for industrial biofuel generation processes, due to their low cost and sustainability, while minimizing the potential to pollute the environment. The esterification, in addition to adding value to lipid sources of low economic value that, many times, are considered contaminating residues of the environment, allows the insertion of new raw materials for the biodiesel production chain, which could represent a new source of income for cooperatives, communities needly, small, and medium entrepreneurs 6 …”

“…In the last few decades, heterogeneous catalysis from nanocatalysts has been extensively studied and used for favoring increasingly high catalytic activities in various processes such as photocatalysis, 7‐14 effluent treatments, 15 and at biodiesel production 16‐19 . Furthermore nanocatalyst plays a major role in catalysis (ie, biodiesel production) due to its various characteristics including high stability, efficient catalytic activity, easy operational procedure, reusability, and high surface area 6,20,21 . The magnetic nanoparticles (MNPs) help in the easy separation of catalyst and increase its reusability 20,21 .…”

“…Por isso, buscar métodos para utilização da escuma é essencial para viabilizar a ampliação de sistemas de tratamento de esgotos. Na literatura, é relatada a caracterização da fração oleosa da escuma visando à produção de biodiesel, quando essa apresenta elevado teor de óleos e graxas (OLIVEIRA et al, 2014;DI BITONTO et al, 2016). Outro uso mencionado é a desidratação e utilização do potencial calorífico da escuma para geração de energia (MAGDZIARZ & WILK, 2013).…”
