“…Dealing with the same amount per sample (80% glycerin and 20% pig manure), Nuchdang and Phalakornkule (2012) registered that the ratio of propionic and butyric acid in the sample did not indicate any imbalance in anaerobic decomposition. Nartker et al (2014) also observed that, when exceeding the 70% glycerin ratio in the sample associated with sludge, the acetic and propionic acids ratio inhibited anaerobic decomposition.…”

“…Astals et al (2012) obtained a COD reduction of 55.7% ± 3.2 for the sample without glycerin and 84.9% ± 2 for the sample associated with glycerin. Nuchdang and Phalakornkule (2012) registered that the efficiency of COD removal was rather stable, remaining above 80%, in the sample analyzed with glycerin associated with pig manure (80% glycerin and 20% of pig manure). Larsen et al (2013) ) proportion in the reactor (Larsen et al, 2013).…”

“…Extensive amounts of pig manure (PM) have become a major contributor to soil, water, and air pollution (Windisch 2001;Li and Chen 2005;Song et al 2012). PM largely contains organic matter that is characterized by a suitable ratio of chemical oxygen demand (COD) to total solid (TS) for anaerobic digestion (AD) (Nuchdang and Phalakornkule 2012;Giuliano et al 2013). AD is the most efficient practice for the management of PM because of the renewable biogas energy it provides and because of the suitability of the digested matter as a fertilizer for planting (Walsh et al 2012;Xie et al 2012;Giuliano et al 2013;Muller et al 2013).…”
