Flaring to dispose of natural gas has increased in the United States and is typically assumed to be 98% efficient, accounting for both incomplete combustion and venting during unintentional flame...
Abstract - Large ruminant production systems (dairy, beef, buffaloes and yaks) in China have experienced significant changes during the last 30 years driven by increased demand for milk...
Methane emissions from the natural gas supply chain are a key factor in determining the greenhouse gas footprint of natural gas production and use. Recent estimates of these emissions have varied...
Soil type and returning straw to the field are the important factors that regulate CH4 formation in paddy soil, and the variations of biogeochemical parameters and methanogens...
Abstract - Anaerobic digestion (AD) treatment of agricultural and animal waste can be considered as a means of enabling environmental remediation. This research investigated two conditions of...
The aim of this work was to study a hybrid bioreactor landfill technology for landfill methane production from municipal solid waste. Two laboratory-scale columns were operated for about ten...
Abstract - In the past decade biogas production has experienced a strong increase in Germany, and along with that the demand for biogas substrate increased equally. In most cases, maize is used as...
Abstract - This paper aims to propose consistent Life Cycle Assessment and Life Cycle Costing metrics and indices and to test them to assess an anaerobic digester on a dairy farm. The...
This policy update looks at a proposed 2014 update by Mexico's Secretariat of Environment and Natural Resources (SEMARNAT) to existing emissions standards regulating particulate matter (PM),...
The microbial community structure of a stable pilot-scale thermophilic continuous stirred tank reactor digester stabilized on poultry litter was investigated. This 40-m3 digester...
