“…Digester failure due to ammonia inhibition is usually a result of the accumulation of volatile fatty acids (VFA) to a point where the buffering capacity of the digester is broken and the pH falls to <6 with a corresponding loss of methane production and a reduction in the methane content of any biogas produced (Abouelenien et al, 2014;Fricke et al, 2007). Using CM as the sole feedstock will in most cases result in digester failure as concentrations of TAN and free ammonia (FA) exceed values that can be tolerated.…”

“…For animal manures this can be achieved by mixing with agricultural crops, as suggested by a number of researchers; this may also have the benefit of improving the volumetric methane production of the digester and thus its economic performance (Rajagopal et al, 2013). The co-digestion of cattle slurry with up to 50% fruit and vegetable wastes can provide a good methane yield (Callaghan et al, 2002) and an increase in methane production of 93% has been reported for chicken manure compared to its mono-digestion (Abouelenien et al, 2014). A theoretical study calculated that daily methane production could be improved approximately 1.2-fold by co-digestion of maize silage (MS) with cattle manure and CM (Yangin-Gomec & Ozturk, 2013).…”

“…CM is a mixture of bird droppings and bedding material which usually contains 25% or more dry matter and is rich in nitrogen (Abouelenien et al, 2014). MS typically contains around 30% dry matter with a higher lignocellulosic and lower nitrogen content than CM.…”

The feasibility of co-digestion of chicken manure (CM) and maize silage (MS) without water dilution was investigated in 5-L digesters. Specific methane production (SMP) of 0.309 L CH 4 g -1 volatile solids (VS) was achieved but only at lower %CM. Above a critical threshold for total ammonia nitrogen (TAN), estimated at 7 g N L -1 , VFA accumulated with a characteristic increase in acetic acid followed by its reduction and an increase in propionic Methanogenesis was completely inhibited at TAN of 9 g N L -1 . The low digestibility of the mixed feedstock led to a rise in digestate TS and a reduction in SMP over the 297-day experimental period. Methanogenesis appeared to be failing in one digester but was recovered by reducing the %CM. Co-digestion was feasible with CM ≤20% of feedstock VS, and the main limiting factor was ammonia inhibition.

“…The mono-digestion of livestock manure also results in low methane production due to the inhibition of anaerobic digestion by the ammonia byproduct produced from organic nitrogen decomposition (Abouelenien et al 2014). Thus, the co-digestion of lignocellulosic biomass and livestock manure should balance the C/N ratio and improve methane production.…”

Methane and ethanol were co-produced from different feedstock, including a mixture of dairy manure and soybean straw (DMS), a mixture of pig manure and soybean straw (PMS), and soybean straw alone (SS), after anaerobic digestion times of 30 and 60 days in mesophilic conditions. Digesting DMS for 60 days led to the highest methane yield of 115.3 g/kg dry raw feed; however, the lowest ethanol yield of 88 g/kg dry raw feed was observed. After 30 days, SS yielded the lowest methane levels (45.2 g/kg dry raw feed) but the highest ethanol levels (113.5 g/kg dry raw feed). Analysis of the net energy balance showed that the highest net energy balance, 6549 kJ/kg of dry raw feedstock, was achieved from the digestion of DMS for 60 days. Overall, both the type of feedstock and length of digestion time played important roles in the integrated processing of methane and ethanol from livestock manure and straw.

RESUMOPara o aumento contínuo da produção de alimentos com o intuito de suprir a demanda crescente da população, se tornam necessárias ações para minimizar os efeitos provocados pelos dejetos quando lançados no ambiente. Estudou-se o processo de codigestão anaeróbia de dejetos bovinos e suínos como alternativa para tratamento destes resíduos. Além disso, investigou-se a eficiência do biofertilizante produzido em cultura de milho. Fez-se o processo de codigestão anaeróbia com a mistura de resíduos de suíno e bovino (3:1) e fração de sólidos de 8,9%. O biofertilizante produzido foi aplicado em cultivo de milho e avaliado conforme o crescimento e desenvolvimento da planta por teste de Tukey. Observou-se a redução da matéria orgânica e a estabilização do processo em 20 dias de tratamento. De acordo com a avaliação do potencial de fertilização, nos cultivos com os biofertilizantes produzidos, os resultados foram similares à adubação comercial, considerando como parâmetros a altura da planta e o diâmetro do colmo. O fertilizante produzido no estudo possui estabilidade biológica e matéria orgânica que pode ajudar a retenção dos nutrientes no solo, podendo ser considerado uma boa fonte de nutriente para a cultura do milho.Palavras-chave: Degradação Orgânica; Adubação; Gramíneas; Altura da Planta; Diâmetro de Colmo. ABSTRACT Assessment of the Fertilizer Potential Generated in Anaerobic Co-digestion Process fromSwine and Cattle Residues in Maize Crop. For continued increases in food production in order to growing demand of the population becomes necessary actions to minimize the effects caused by wastes when released into the environment. It was studied anaerobic co-digestion process of cattle and swine manures, as an alternative treatment of these wastes and to investigate the efficiency of biofertilizer produced in a maize crop. There was a process of anaerobic co-digestion with the mixture of swine and cattle residues (3:1) and solid fraction of 8.9%. The produced biofertilizer was applied in cultivation of maize and evaluated according to the growth and development of the plant
