One way of making livestock farming a more sustainable practice is to raise cattle organically. However, regardless of the production system, there is a generation of residues that can be converted into energy resources using biodigesters. This study aimed to evaluate the addition of inoculum in the anaerobic biodigestion of cattle manure under organic (OPS) and conventional production systems (CPS) in an Indian model biodigester. The physicochemical (pH, EC, TS, VS, DBO, and COD) and microbiological characteristics of the affluent and effluent, as well as the production, potential, and qualitative characteristics of the biogas, were evaluated. CPS showed higher reductions in TS, VS, BOD, and COD than OPS, with the highest effect of biogas production. Regarding the effect of inoculum addition, the treatment with 20% inoculum provided in both production systems high acceleration at the starting point of biogas production and increased energy potential, as well as high reductions in VS, BOD, and COD. Thus, there is a need to use 20% inoculum for high biogas productivity, regardless of the production system.

A região Centro-Oeste concentra os estados brasileiros com maiores escalas de produção da suinocultura, facilitando a logística de produção e distribuição de produtos (carne) e coprodutos de valor agregado (biogás e biofertilizantes). A atividade produz diariamente grandes quantidades de biomassa residual animal, a qual pode atender demanda energética local e/ou comercialização do excedente, bem como destino adequado dos efluentes gerados. Metodologia para determinação da quantidade de biogás (m³.ano-1) e eletricidade (kWh.ano-1), considera rebanho suíno efetivo (2008-2016) nas micro e mesorregiões do estado de Mato Grosso do Sul. Conclusões principais incluem quantificação do potencial energético em ~4% da eletricidade consumida no estado, bem como importância dos coprodutos (biogás e biofertilizante) com valor agregado relevantes no custeio da atividade da suinocultura e na sustentabilidade ambiental.

“…Comparing organic and conventional management in dairy farms, Matos et al [66] observed higher biogas yield from cow manure produced by dairy herds under the conventional production system compared to AD with cow manure under the organic production system. These differences in methane yield may be due to the different diet fed to the animals, as in the conventional management diets are based on concentrate that provided more appropriate substrates for the AD process than organic diets, mainly based on roughage.…”

Recent Updates on the Use of Agro-Food Waste for Biogas Production

The production of biogas from anaerobic digestion (AD) of residual agro-food biomasses represents an opportunity for alternative production of energy from renewable sources, according to the European Union legislation on renewable energy. This review provides an overview of the various aspects involved in this process with a focus on the best process conditions to be used for AD-based biogas production from residual agro-food biomasses. After a schematic description of the AD phases, the biogas plants with advanced technologies were described, pointing out the strengths and the weaknesses of the different digester technologies and indicating the main parameters and operating conditions to be monitored. Subsequently, a brief analysis of the factors affecting methane yield from manure AD was conducted and the AD of fruit and vegetables waste was examined. Particular attention was given to studies on co-digestion and pre-treatments as strategies to improve biogas yield. Finally, the selection of specific microorganisms and the genetic manipulation of anaerobic bacteria to speed up the AD process was illustrated. The open challenges concern the achievement of the highest renewable energy yields reusing agro-food waste with the lowest environmental impact and an increment of competitiveness of the agricultural sector in the perspective of a circular economy.
