Cows are responsible for about 40% of global methane emissions. Methane is the gas passed or belched by the world's 1.4 billion cattle. In Scotland, cattle can be found grazing on the lush green pastures. Some environmentalists believe that when it comes toglobal warming, meat, especially b...
Not all mammals emit the same amount of methane when they digest food. Pigs have body weights similar to ours but emit ten times as much methane. Diet plays a role, too—sheep eating grass burp up 11 times as much methane as pigs. However, cattle are the undisputed heavyweight champions ...
Second ismethanefrom livestock.Now we hear a lot of jokes about what cows do and all that kind of thing,but the science is actually really clear.Livestock are a huge emitter of methane,and methane is a very big d...
To figure the Green Premiums on materials, you need to understand where emissions come from when we make things. I think of it in three stages:We emit greenhouse gases (1) when we use fossil fuels to generate the electricitythat factories need to run their operations;(2) when we use them...
captured. "Some others assume as much as 96%, but they assume that CO2released in the smoke gas from the burner that provides the heat for the reaction is also captured. We have only assumed capturing the CO2released in the steam-methane gas reaction itself, which is the more economical ...
The methane they burp and fart out every year has the same warming effect as 2 billion tons of carbon dioxide, accounting for about 4 percent of all global emissions. Burping and farting natural gas is a problem that’s unique to cows and other ruminants, like sheep, goats, deer, and ...
Cars, planes, power plants and factories all emit GHG. The Kyoto Protocol, an international GHG agreement, defines six troubling types of emissions: Carbon dioxide (CO2): When fossil fuels, waste and plant matter burn, they emit CO2, the most common GHG emission. Methane (CH4): Landfills, ...
To put these numbers into a bit more context, it might be helpful to just review the definition of a carbon footprint. A carbon footprint is the total amount of greenhouse gases (which includes carbon dioxide as well as methane) that are generated by actions—in this case to grow, harves...
Once the cellulosic material exceeds 250 °C, pyrolysis occurs as an endothermic process [35,36], resulting in the irreversible polymer decomposition by producing tar (of which levoglucosan is the main component), flammable gases (methane, ethane, and carbon monoxide), non-flammable gases (carbon...
