What is Landfill?
[[File:Wysypisko.jpg|thumb|A landfill in [[Poland]]]] [[File:WasteFinalDeposited.jpg|thumb|Uncontrolled '''garbage dump'''.]] A '''landfill''' is a place where [[waste]] is kept. Waste is usually [[burial|buried]] in landfills, but it may first be sorted to remove any [[Recycling|recyclable]] materials. Landfills have a bad [[odor|smell]] and look bad, therefore are usually located far away from where people live. Once the waste is crushed into very small pieces, it is buried, but without oxygen, a dangerous gas called [[methane]] is created. This process is called [[anaerobic digestion]]. In some countries, the methane from landfills is used to generate [[energy]]. == Large landfills in the United States == Roosevelt Regional Landfill, Roosevelt, [[Washington (state)|Washington]].<ref>{{cite web|url=http://www.republicservices.com/site/roosevelt-wa/en/pages/location.aspx|title=Republic Services Roosevelt Regional Landfill|accessdate=9 February 2014|work=Republic Services}}{{Dead link|date=January 2021 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><br /> Denver Arapahoe Disposal Site, [[Aurora]], [[Colorado]].<ref>{{cite web|url=http://www1.wmsolutions.com/facilities/details/id/53|title=Denver Arapahoe Disposal Site (DADS) Landfill|accessdate=9 February 2014|work=Waste Management|archive-date=26 May 2014|archive-url=https://web.archive.org/web/20140526191514/http://www1.wmsolutions.com/facilities/details/id/53|url-status=dead}}</ref><br /> Columbia Ridge Landfill, Arlington, [[Oregon]].<ref>{{cite web|url=http://wmnorthwest.com/landfill/columbiaridge.htm|title=Columbia Ridge Recycling and Landfill|accessdate=9 February 2014|work=Waste Management}}</ref><br /> Pine Tree Acres, Lenox, [[Michigan]].<ref>{{cite web|url=http://pinetreeacreslandfill.wm.com/index.jsp|title=Pine Tree Acres Landfill|accessdate=8 February 2014|work=Waste Management}}</ref><br /> ==Other large landfills== *[[Smokey Mountain]] in [[Manila]], [[Philippines]]s ==References== {{reflist}} [[Category:Waste management]]
