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, ...
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...
A bottle contains methane gas molecules at a temperature of 351.7 K. Methane, CH_4 is a polyatomic, non-linear molecule(6 degrees of freedom) and the mass of a single methane molecule is 2.66 \times10 How much energy is released when condensing 1.00g of g...
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. ...
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...
Last but not least, cleaner boilers and furnaces means improved safety. With much less manual internal cleaning of furnaces required, human exposure to molten ash and furnace gas is greatly reduced and dangerous techniques such as explosion cleaning are avoided. ...
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...
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不...
Research indicates that the U.S. oil and gas industry emits 16.9 million metric tons of methane every year, according to the International Energy Agency.3Some of this methane is inadvertently leaked through faulty equipment or deliberately vented into the atmosphere between extractions. The Environmen...
