“…Los residuos de las trampas de grasas se derivan del pretratamiento de aguas residuales de restaurantes, cadenas de comida rápida y procesadores de alimentos. Se extraen las grasas de las trampas interceptoras de grasa con un contenido de sólidos entre 5 y 6% [7] (GTC. La grasas y aceites, son subproductos generados en los procesos de cocción, contemplando tanto grasas animales como aceites vegetales.…”

La inadecuada disposición de residuos trae consigo una serie de impactos ambientales negativos tanto para los seres humanos como para la biota en general. Uno de los residuos municipales que representa la principal fuente de impactos y riesgos ambientales adversos en los vertederos tradicionales es la fracción orgánica biodegradable, especialmente los residuos de las trampas de grasas y aceites. Las técnicas para su disminución en vertederos comprenden desde generación de biodiesel hasta el compostaje. En el presente estudio se realiza una descripción del estado del arte de algunas metodologías utilizadas a nivel mundial para llevar a cabo el compostaje de los residuos de las trampas de grasas y aceites; esto con la intención de lograr minimizar los impactos ambientales generados por la inadecuada disposición de los mismos. Se determinó que, por las condiciones climatológicas habituales de nuestro país, es posible utilizar los procesos de compostaje en el tratamiento de los residuos sólidos provenientes de sistemas de trampas de grasas y aceites.

“…During this stage, the biologically resistant substrates such as lignocellulose and lignin are degraded. The maturation phase of composting has a large bearing on the suitability of the end product for a particular use (Brewer & Sullivan, 2003;Wilkinson et al, 2009). Many authors have defined various optima for the composting process, including a carbon to nitrogen ratio (C:N) of between 25:1 and 30:1, moisture content within the range of 50-60% (w/w), porosity of 35-45% and oxygen levels of >10% by volume (Table 1).…”

Meat processing grease wastes were composted with lignocellulosic material. Judging by the reduction in the yield of compost lipophilic extract, grease was degraded during the first 20 days of composting. Compost humic acids (HA) and fulvic acids (FA) were characterized by elemental analysis, Fourier transform infrared (FT-IR) spectroscopy and analytical pyrolysis. The compost HA and FA fractions contained a ligno-protein complex. The presence of grease (6.7% dry weight) during composting had a slight influence on the chemical composition of HA and FA. Analytical pyrolysis indicated that, during composting, major changes were observed in the FA fraction, namely, the proportion of nitrogen-bearing compounds increased and carbohydrate-derived products decreased drastically in the final compost. In addition, the shortening of the aliphatic chains of lignin-derived compounds was observed with an increase in the C6C(0-2)/C6C3 ratio in pyrolysates.
