addition of Cattle Manure to sheep bedding allows vermicomposting process and improves vermicompost quality
Waste Management, 2017Co-Authors: Taiana Cestonaro, Monica Sarolli Silva De Mendonca Costa, Luiz Antonio De Mendonca Costa, Dercio Ceri Pereira, Marcos Antonio Teofilo Rozatti, Marcos Felipe Leal MartinsAbstract:Abstract Animal waste is usually a good substrate for vermicomposting. However, numerous animal husbandry systems use bedding that consists primarily of lignocellulosic substrates, which hinders earthworm and microorganism’s development and thus, the entire bioconversion process. One possible solution is to mix the used bedding with other waste materials that are more amenable to earthworm ingestion and can provide better conditions for earthworm population growth. Here, we have aimed to examine the effectiveness of such procedure by mixing rice-husk-based sheep bedding with Cattle Manure in different proportions (0%, 25%, 50%, 75% and 100%). We have carried out vermicomposting experiments in benchtop vermireactors inoculated with 0.88 kg of dry matter (sheep bedding + Cattle Manure). Data used in the Principal Component Analysis were the multiple vermicomposting variables (i.e., EC; pH; HA/FA and C/N ratios; P, K, cellulose, and hemicellulose content). The effect of the treatment on earthworm count was analyzed with ANOVA. We have observed that the addition of at least 25% of Cattle Manure to sheep bedding allows vermicomposting process but it is necessary 148 days to obtain a stabilized vermicompost. However, increasing the proportion of Cattle Manure to sheep bedding, the vermicomposting time decreases proportionally to 94 days. We concluded that vermicomposting can be considered a bioprocess to stabilize rice husk after being used as sheep bedding.

the anaerobic co digestion of sheep bedding and 50 Cattle Manure increases biogas production and improves biofertilizer quality
Waste Management, 2015Co-Authors: Taiana Cestonaro, Monica Sarolli Silva De Mendonca Costa, Luiz Antonio De Mendonca Costa, Dercio Ceri Pereira, Marcos Antonio Teofilo Rozatti, Higor Eisten Francisconi Lorin, Leocir Jose CarneiroAbstract:Abstract Sheep Manure pellets are peculiarly shaped as small ‘capsules’ of limited permeability and thus are difficult to degrade. Fragmentation of Manure pellets into a homogeneous mass is important for decomposition by microorganisms, and occurs naturally by physical shearing due to animal trampling, when sheep bedding is used. However, the high lignocellulose content of sheep bedding may limit decomposition of sheep Manure. Here, we evaluated if co-digestion of sheep bedding with Cattle Manure would improve the yield and quality of the useful products of anaerobic digestion of sheep bedding—biogas and biofertilizer—by providing a source of nutrients and readily available carbon. Mixtures of sheep bedding and Cattle Manure in varying proportions (0%, 25%, 50%, 75%, or 100% Cattle Manure) were added to 6-L digesters, used in a batch system, and analyzed by uni and multivariate statistical tools. PC1, which explained 64.96% of data variability, can be referred to as ‘organic fraction/productivity’, because higher rates of organic fraction consumption (COD, cellulose and hemicellulose contents) led to higher digester productivity (biogas production, nutrient concentration, and sample stability changes). Therefore, productivity and organic fraction variables were most influenced by Manure mixtures with higher (⩾50%) or lower (⩽25%) ratios of Cattle Manure, respectively. Increasing the amount of Cattle Manure up to 50% enhanced the biogas potential production from 142 L kg −1 TS (0% of Cattle Manure) to 165, 171, 160 L biogas kg −1 TS for the mixtures containing 100%, 75% and 50% of Cattle Manure, respectively. Our results show that the addition of ⩾50% Cattle Manure to the mixture increases biogas production and improves the quality of the final biofertilizer.

improving the nutrient content of sheep bedding compost by adding Cattle Manure
Journal of Cleaner Production, 2015Co-Authors: Monica Sarolli Silva De Mendonca Costa, Taiana Cestonaro, Luiz Antonio De Mendonca Costa, Dercio Ceri Pereira, Marcos Antonio Teofilo Rozatti, Leocir Jose Carneiro, Higor Eisten Francisconi LorinAbstract:Abstract Sheep bedding has favorable characteristics for composting, such as providing readily assimilable carbon and facilitating aeration, which are essential for the growth of composting microorganisms. However, when composted alone, it may have disadvantages related to the time of composting and to the fertilizer value of the compost produced, due to its high lignocellulosic content. To investigate whether Cattle Manure could improve composting of sheep bedding as well as the agronomic quality of the compost produced, we mixed Cattle Manure with sheep bedding in varying proportions (0–100%) and evaluated several parameters of the composting process and of the final compost, such as changes in temperature, macronutrients, and carbon content before and after the composting process. The addition of ≥50% Cattle Manure to the mixture increased composting efficiency, resulting in a more stable compost with higher nutrient content. The high content of rice husk in sheep bedding limited the addition of higher proportions of this component to the composting mixture. We identified an efficient way to improve the quality of compost generated during waste management of sheep Manure and bedding.

Our results show that the addition of ⩾50% Cattle Manure to the mixture increases biogas production and improves the quality of the final biofertilizer.

The anaerobic co-digestion of sheep bedding and ⩾50% Cattle Manure increases biogas production and improves biofertilizer quality
Waste management (New York N.Y.), 2015Co-Authors: Taiana Cestonaro, Monica Sarolli Silva De Mendonca Costa, Luiz Antonio De Mendonca Costa, Dercio Ceri Pereira, Marcos Antonio Teofilo Rozatti, Higor Eisten Francisconi Lorin, Leocir Jose CarneiroAbstract:Sheep Manure pellets are peculiarly shaped as small 'capsules' of limited permeability and thus are difficult to degrade. Fragmentation of Manure pellets into a homogeneous mass is important for decomposition by microorganisms, and occurs naturally by physical shearing due to animal trampling, when sheep bedding is used. However, the high lignocellulose content of sheep bedding may limit decomposition of sheep Manure. Here, we evaluated if co-digestion of sheep bedding with Cattle Manure would improve the yield and quality of the useful products of anaerobic digestion of sheep bedding--biogas and biofertilizer--by providing a source of nutrients and readily available carbon. Mixtures of sheep bedding and Cattle Manure in varying proportions (0%, 25%, 50%, 75%, or 100% Cattle Manure) were added to 6-L digesters, used in a batch system, and analyzed by uni and multivariate statistical tools. PC1, which explained 64.96% of data variability, can be referred to as 'organic fraction/productivity', because higher rates of organic fraction consumption (COD, cellulose and hemicellulose contents) led to higher digester productivity (biogas production, nutrient concentration, and sample stability changes). Therefore, productivity and organic fraction variables were most influenced by Manure mixtures with higher (⩾ 50%) or lower (⩽ 25%) ratios of Cattle Manure, respectively. Increasing the amount of Cattle Manure up to 50% enhanced the biogas potential production from 142 L kg(-1)TS (0% of Cattle Manure) to 165, 171, 160 L biogas kg(-1)TS for the mixtures containing 100%, 75% and 50% of Cattle Manure, respectively. Our results show that the addition of ⩾ 50% Cattle Manure to the mixture increases biogas production and improves the quality of the final biofertilizer.

improving the nutrient content of sheep bedding compost by adding Cattle Manure
Journal of Cleaner Production, 2015Co-Authors: Monica Sarolli Silva De Mendonca Costa, Taiana Cestonaro, Luiz Antonio De Mendonca Costa, Dercio Ceri Pereira, Marcos Antonio Teofilo Rozatti, Leocir Jose Carneiro, Higor Eisten Francisconi LorinAbstract:Abstract Sheep bedding has favorable characteristics for composting, such as providing readily assimilable carbon and facilitating aeration, which are essential for the growth of composting microorganisms. However, when composted alone, it may have disadvantages related to the time of composting and to the fertilizer value of the compost produced, due to its high lignocellulosic content. To investigate whether Cattle Manure could improve composting of sheep bedding as well as the agronomic quality of the compost produced, we mixed Cattle Manure with sheep bedding in varying proportions (0–100%) and evaluated several parameters of the composting process and of the final compost, such as changes in temperature, macronutrients, and carbon content before and after the composting process. The addition of ≥50% Cattle Manure to the mixture increased composting efficiency, resulting in a more stable compost with higher nutrient content. The high content of rice husk in sheep bedding limited the addition of higher proportions of this component to the composting mixture. We identified an efficient way to improve the quality of compost generated during waste management of sheep Manure and bedding.
