Livestock Water Recycling, Inc., also referred to as LWR, is a privately owned Canadian company based in Calgary, Alberta. The environmental company focuses on livestock manure management at dairy and hog CAFO livestock operations. The company has built and manufactured industrial waste water treatment systems throughout North America since 1991. It conducts all design, production and manufacturing at its office in Calgary, Alberta. Initially the company focused on wastewater remediation of oil and gas sites. In 2004 it identified a new opportunity in the agricultural industry with regards to manure management. == Manure Management == Manure management is an increasing issue among CAFO livestock operators. Large CAFO operations help sustain the food industry with its production of food sources. The more food produced the more manure that is produced. Manure is often stored and spread onto adjacent farmland since it is rich in nutrients and is a good fertilizer. Since the livestock industry is so important, manure management practices need to be developed to protect the environment – increased government regulations have been put into place. The amount of manure spread onto farm land affects the concentration of nutrients in the soil, water run-off can transport nutrients such as phosphorus or nitrogen into fresh water streams. High volumes of these nutrients can disrupt the natural ecosystems causing algae blooms, etc. Other common manure issues include: * Strong odors associated with manure storage lagoons and ponds * Expensive costs associated with hauling manure * Increased flies and other insects at farming operation * Operation expansion requires additional land or higher costs for hauling manure North America has approximately 10 million dairy cows 〔http://www.dairyinfo.gc.ca/pdf/world_number_of_dairy_cows.pdf〕 and 76 million hogs.〔http://nationalhogfarmer.com/site-files/nationalhogfarmer.com/files/archive/nationalhogfarmer.com/images/NHF_SOIReport__2011.pdf〕 The dairy and hog industries in North America continue to consolidate into larger CAFO operations resulting in an increase in herd size and a decrease in the number of operations. Certain areas of North America are concentrated with dairy and hog operations. For example, California produces the most milk in North America;〔http://www.progressivepublish.com/downloads/2012/general/2012_pd_stats_lowres.pdf〕 whereas Iowa is the top hog producer.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Livestock water recycling」の詳細全文を読む スポンサード リンク
