Estudio de la relación de mezcla de cosustratos para la codigestión anaerobia de sobrantes alimenticios de restaurante con estiércol bovino
La generación mundial de sobrantes alimenticios de restaurante (SAR) sobrepasa actualmente los 670 millones de toneladas al año y gestionarlos ha causado una problemática relacionada con la contaminación de aguas subterráneas, la generación de malos olores, entre otras. Por lo tanto, han surgido est...

The global generation of restaurant food waste (RFW) now exceeds 670 million tons per year and manage them has caused problems related to pollution of groundwater
generating odors
among others. Therefore
strategies have emerged as anaerobic digestion (AD)
which in addition to allowing stabilize the residue which is measured at turning it into an energy source as it is biogas. However
the characteristics of the RFW
such as high biodegradability and nutritional imbalance in terms of micro and macronutrients
generates instabilities in AD systems leading them to fail
when small values of inoculum substrate ratio (ISR) are used. To avoid this instability anaerobic co-digestion (ACoD)
digestando simultaneously SAR and cattle manure (CM)
in order to exploit their complementary characteristics is used. Therefore
and to achieve the best possible returns under the management of RFW ACoD with CM
in this research the effects of variable mixing ratio and organic load on yield and process stability were evaluated. Initially
a study of the effects is performed by a design of experiments 22
where it was found that both variables and their interactions have a significant effect on the system behavior and then is carried through a central composite design
a study curvature and performing regions. During the experiment the concentration of volatile fatty acids
total alkalinity
pH and daily biogas production was monitored. The results showed that at an organic load of 22 gVS / l and mixture ratio of 83:17 higher yields are obtained
