摘要：
Waste foundry sands are industrial wastes of important quantity. Because of the partially very high contamination of these sands with polyaromatic hydrocarbons (PAH), some of them potent carcinogens, dumping of these sand in landfills without appropriate safety measures, or use in road and landscape construction is very problematic. The concept of a thermic-mechanical regeneration, which offers not only ecological, but also economic advantages, is introduced.
