Assessment of Biomethane Potential from Waste Activated Sludge in Swine Wastewater Treatment and Its Co-Digestion with Swine Slurry, Water Lily, and Lotus Open
Waste activated sludge (WAS), a byproduct of livestock wastewater treatment, poses significant disposal challenges due to its low biodegradability and potential environmental impact. Anaerobic digestion (AD) offers a sustainable approach f…
Ventilation and Bedding Effects on Air Quality in Swine Confinement Systems Open
Reducing odor and particulate matter (PM) in confined swine houses is critical for environmental sustainability and animal welfare. This study evaluated the effects of different housing designs and bedding systems on aerial environmental c…
Bioconversion of Poultry Litter into Insect Meal and Organic Frasstilizer Using Black Soldier Fly Larvae as a Circular Economy Model for the Poultry Industry: A Review Open
Poultry litter waste management poses a significant global challenge, attributed to its characteristics (odorous, organic, pathogenic, attracting flies). Conventional approaches to managing poultry litter involve composting, biogas generat…
Biomethane Potential of Beef Cattle Slaughterhouse Waste and the Impact of Co-Digestion with Cattle Feces and Swine Slurry Open
Slaughterhouse waste (SW) poses significant environmental challenges due to its complex composition, but anaerobic digestion offers a way to recover valuable biogas from SW. This study investigated the anaerobic co-digestion of beef cattle…
Biochemical Methane Potential of Swine Slaughter Waste, Swine Slurry, and Its Codigestion Effect Open
The codigestion of slaughter waste with animal manure can improve its methane yield, and digestion parameters; however, limited studies are available for the effectiveness of anaerobic codigestion using swine slaughter waste (SSW) and swin…
The investigation of combined ventilation-biofilter systems using recycled treated wastewater on odor reduction efficiency Open
Objective: The present study aimed to evaluate the performance of odor abatement by using two different ventilation-biofilter systems with recycled stablized swine wastewater.Methods: The performance of odor removal efficiency was evaluate…
Archaeal community structure and underlying ecological processes in swine manure slurry Open
The ecological processes underlying the observed patterns in community composition of archaea in swine manure slurry are poorly understood. We studied the archaeal communities from six swine manure slurry storage tanks using paired-end Ill…
The dynamics of nitrogen derived from a chemical nitrogen fertilizer with treated swine slurry in paddy soil-plant systems Open
A well-managed chemical nitrogen (N) fertilization practice combined with treated swine slurry (TSS) is necessary to improve sustainability and N use efficiency in rice farming. However, little is known about the fate of N derived from che…
Greenhouse gas emissions from cattle production sector in South Korea Open
South Korea has declared to reduce greenhouse gas emissions by 30% compared to the current level by the year 2020. The greenhouse gas emissions from the cattle production sector in South Korea were evaluated in this study. The greenhouse g…
Biochemical Methane Potentials and Organic Matter Degradation of Swine Slurry under Mesophilic Anaerobic Digestion Open
Background/Objectives: Swine slurry is generally used as raw liquid fertilizer and leads environmental pollution. Therefore to overcome that, anaerobic digestion before its field application would reduce pollution and give bioenergy. Metho…
