IMUS (also known as integrated manure utilization system) is an anaerobic digestion technology that converts organic material into biogas that is used to produce electricity, heat and nutrients. [ 1 ] The technology uses waste such as municipal waste, cow manure, sand laden feed lot waste, and food processing waste.
The concept of an animal unit (AU) has traditionally been used in North America to facilitate planning, analysis and administration of forage use by grazing livestock, but the term has also had other applications (in relation to odor control regulation, feedlot size, manure management, etc.). The term has been variously defined by regulation in ...
The 2003 rule established "non-numerical best management practices" (BMPs) for CAFOs that apply both to the "production areas" (e.g. the animal confinement area and the manure storage area) and, for the first time ever, to the "land application area" (land to which manure and other animal waste is applied as fertilizer).
Converting cow manure to fuel is a growing climate solution, but critics say communities are put at risk.
In 2006 there were about 65,000 dairy farms in the United States, although most had fewer than 200 cows. [3] One "resource auditor" believes it is possible for dairy farms to reach an energy usage of as low as 200 kWhr per cow per year [4] although an analysis of California dairy farms found that 300 kWhr/year was the lowest actually attained.
Cow dung on the ground. Cow dung, also known as cow pats, cow pies, cow poop or cow manure, is the waste product of bovine animal species. These species include domestic cattle ("cows"), bison ("buffalo"), yak, and water buffalo. Cow dung is the undigested residue of plant matter which has passed through the animal's gut.
The manure is usually stored in slurry form (slurry is a liquid mixture of urine and feces). During storage on farm, slurry emits methane and when manure is spread on fields it emits nitrous oxide and causes nitrogen pollution of land and water. Poultry manure from factory farms emits high levels of nitrous oxide and ammonia. [108]
Agricultural equipment is any kind of machinery used on a farm to help with farming. The best-known example of this kind is the tractor . From left to right: John Deere 7800 tractor with Houle slurry trailer, Case IH combine harvester, New Holland FX 25 forage harvester with corn head.
