Our landfills here in the US aren't that organized I'm afraid! I wish they were. Asbestos is what used to be used as an insulating material and it is nearly fire proof. It's not a poison but rather the particles it is made up of are so small that none of the natural filtering devices in the human body, nose hairs, cillia, can capture it so it goes on to become en-lodged in the lungs thus causing cancer. Asbestos is not a threat until disturbed when it creates dust and is inhaled. Most houses built up until around the 1930's and 40's incorporated asbestos. The removal for it is extremely expensive because none of it is allowed to leak out into the environment, therefore the house must be completely sealed for it's removal and the workers are at a high risk for inhalation even with protection, so it's expensive. They just have it in your landfills in Sweden? In case your curious about it: http://www.epa.gov/asbestos/ashome.html
