Livestock fed higher quality feed tend to produce less methane than those fed low quality feed. Swine, since they are not ruminants,have the lowest emissions factor of any class of livestock. The IPCC methane emission factor used by EPA to estimate enteric fermentation from swine is 1.5 kg met...
Based on the results of empirical tests, we find that these three main pollutant emissions in waste gas don not have significant effect on mortality rates. The partial effect estimation for mortality rates, some population characteristics and health situation could produce significant impact, such as...
When landfill gas extraction rates are low, operators often assume it's because of an intractable problem such as perched leachate blocking wells, low permeability or low methane generation rates. Other concerns may include high condensate production, leachate wells producing gas but little leachate, ...
human slash-cut, the excessive use of carbon-containing compounds, and excessive exploitation of limited resources, waste water, waste gas row, and so on. For our own benefit, care homes, is everyone's responsibility to start from little things, from now onwards. ...
In this study, three seasonal waste mixtures generated in wholesale markets were reduced to 10, 6, and 4 mm to assess the influence of seasonality and particle size reduction on anaerobic biodegradability. The methane yield ranged between 298 and 465 mL CH4 g VS−1 (volatile solids). Waste...
IoT can connect every unit, device, asset, machinery, or equipment to a single network. With smart sensors, businesses can then track assets and control equipment. Real-time insights and autonomous control reduces waste and optimizes the entire workflow. Asset-heavy industries like transportation us...
Therefore, predictors of environmental behaviour may be, for example, human values, views on sustainability, and concern about sustainability-relevant issues. Values are commonly defined as desirable trans-situational goals that serve as leading principles in life [56]. These values have been proven ...
plant. In most cases, the amount released is less than the amount consumed by the plant. Farms, grasslands and forests are considered sources or sinks of carbon dioxide, depending on the practices on these lands. For example, cows produce methane, but grass on the farm sequesters the gas. ...
atoday pollution has become a serious international problem our air seas rivers and land have been polluted by waste or poisonous things pollution does great harm not only to human beings but also to animals 今天污染成为了一个严肃的国际问题我们的空气海河,并且土地由废污染了或毒事污染伟大的害处...
(2022), a comprehensive index is calculated to measure country-level ERS based on three indicators: CEs, nitrous oxide emissions, and methane emissions. The data are collected from the World Bank database. We first calculate the emission intensity of each pollutant by using EII,it=pI,itIOit/...
