Capped Landfills Once a landfill is full, it is covered in dirt and more or less preserved. How should this clearly visible area be tagged? Is it disused:landuse=landfill or is a landfill always in use, until it has some other notable use? Or does it stop being a landfill once it has grass growing on it? --Mtc (talk) 03:08, 16 August 2016 (UTC)

I think once it is not in use any more (i.e. once there are no more waste brought to this place), it should be tagged with disused:landuse=landfill or more often with abandoned:landuse=landfill (disused: should be used when it is possible to use the site again; compare Key:abandoned: and Key:disused:). abandoned:landuse=landfill can be used in combination with other tags such as natural=scrub, natural=wood, natural=grassland or even landuse=forest.
