Anaerobic co-digestion of swine manure and forage at two harvesting ages
Oliveira,Juliana Dias de; Orrico,Ana Carolina Amorim; Leite,Brenda Kelly Viana; Schwingel,Alice Watte; Orrico Junior,Marco Antonio PrevidelliABSTRACT: The co-digestion of swine manure with vegetable waste is an alternative that can increase the production of biogas and methane generated by the isolated digestion of manure. However, recommendations that are based on the best ratio between manure and forage, as well as the age of harvest, are still scarce in the literature. This study was conducted to evaluate inclusions (0, 25, 50, 75 and 100%) of th...
Anaerobic co-digestion of swine manure with sweet potato or cassava in differen...
Villa,Lisandra Maraia; Orrico,Ana Carolina Amorim; Akamine,Luana Alves; Lucas Junior,Jorge de; Sunada,Natália da SilvaABSTRACT: Anaerobic co-digestion (AcoD) of waste is a method of increasing methane (CH4) yield and improving biofertilizer quality. This study aimed to evaluate the best AcoD conditions for swine manure (SM) with sweet potato (SP) or cassava (C) in different amounts in semi-continuous biodigesters. Initially, using batch biodigesters, an AcoD test of the SM with SP or C was performed, adopting carbon/nitrogen (...
The quality of crude glycerine influences the fermentation and nutritive value ...
Schwingel,Alice Watte; Fernandes,Tatiane; Orrico Junior,Marco Antonio Previdelli; Orrico,Ana Carolina Amorim; Lucas Junior,Jorge deABSTRACT We aimed to evaluate the effects of crude glycerine purity and levels of glycerol on the fermentative profile, microorganisms counting, and nutritional value of Piatã grass silage. The experiment was carried out in a 3×3+1 completely randomized factorial design using three different types of crude glycerine [low purity (40% of glycerol), medium purity (60% glycerol), and high purity (80% glycerol)], th...
Productive performance and quantitative carcass traits of lambs fed saccharine ...
Manarelli,Débora Maurício; Orrico Junior,Marco Antonio Previdelli; Retore,Marciana; Vargas Junior,Fernando Miranda de; Silva,Mabio Silvan José daAbstract: The objective of this work was to evaluate the productive performance and carcass traits of lambs fed silages of different types of sorghum and corn. Thirty-two uncastrated male Suffolk lambs were used. The experimental design was completely randomized, with four treatments (silages) and eight replicates (animals). Silages of the GrandSilo forage sorghum, BRS 506 saccharine sorghum, BRS 511 saccharine...
Anaerobic co-digestion of animal manure at different waste cooking oil concentr...
Sunada,Natália da Silva; Orrico,Ana Carolina Amorim; Orrico Junior,Marco Antonio Previdelli; Lucas Junior,Jorge de; Lopes,Walter Renato TeixeiraABSTRACT: This study aimed to obtain the best dose of waste cooking oil inclusion for the co-digestion of substrates prepared with dairy cattle and swine manure in order to maximize solids reductions and biogas yield. Analyses of total solids (TS), volatile solids (VS), and neutral detergent fiber (NDF) were performed during the loading and unloading of digesters, while biogas yield was measured twice a week. T...
Crude glycerin in co-composting with laying hen manure reduces N losses
Orrico Junior,Marco Antonio Previdelli; Orrico,Ana Carolina Amorim; Fava,Aldo Felipe; Sunada,Natália da Silva; Schwingel,Alice WatteABSTRACT: The composting of laying hen manure is an efficient way of treating waste and producing an organic fertilizer with excellent characteristics; however, the high N losses reduce its concentration in the resulting fertilizer. Associating this residue with crude glycerin (CG) promotes a better C:N ratio and contributes to higher N retention during composting, with improvements in solids reduction and prod...
The use of crude glycerin as an alternative to reduce fermentation losses and e...
Orrico Junior,Marco Antonio Previdelli; Velazquez Duarte,José Augusto; Crone,Carla; Neves,Franciely de Oliveira; Reis,Ricardo AndradeABSTRACT The objective of this study was to evaluate fermentation losses and the nutritional value of silage of Brachiaria brizantha cv BRS Piatã ensiled with different levels of crude glycerin. The experiment followed a 4 × 2 completely randomized factorial design with four doses of crude glycerin (0, 100, 200, and 300 g kg–1 of DM silage) and two cutting ages (45 and 60 days) with four replicates per treatmen...
Crude glycerin in anaerobic co-digestion of dairy cattle manure increases metha...
Simm,Silvana; Orrico,Ana Carolina Amorim; Orrico Junior,Marco Antonio Previdelli; Sunada,Natália da Silva; Schwingel,Alice WatteABSTRACT Anaerobic digestion of crude glycerin (CG) along with animal waste has been an excellent option for increasing the production of biogas and methane to achieve efficiency in the treatment of both residues. This study aimed to evaluate improvements in specific productions of biogas and methane, reductions in solid and fibrous components in substrates prepared with dairy cattle manure and CG (containing 1...

Schwingel,Alice Watte; Orrico,Ana Carolina Amorim; Orrico Junior,Marco Antonio Previdelli; Sunada,Natalia da Silva; Centurion,Stanley RibeiroRESUMO O objetivo foi avaliar o desempenho da co-digestão anaeróbia de dejetos de suínos associados com crescentes doses de glicerina bruta, adotando-se diferentes tempos de retenção hidráulica (TRH). O delineamento utilizado foi inteiramente casualizado em esquema fatorial 3x4, três TRH (10; 17 e 24 dias) e quatro doses de glicerina bruta (0; 5; 10 e 15% dos sólidos totais), com quatro repetições por tratament...
Co-digestion of swine excreta associated with increasing levels of crude glycerin
Orrico Junior,Marco Antonio Previdelli; Schwingel,Alice Watte; Centurion,Stanley Ribeiro; Orrico,Ana Carolina AmorimABSTRACT The objective of this research was to evaluate the performance of anaerobic co-digestion of swine excreta associated with increasing doses of crude glycerin and different hydraulic retention times (HRT). A completely randomized design was adopted in a 3 × 4 factorial arrangement composed of three HRT (10, 17, and 24 days) and four crude glycerin doses (0, 5, 10, and 15 g/100 g of total solids [TS]), wi...
