The company has acquired over the last twenty years extensive experience in the challanges of pretreatment of metal foundry and has achieved to date 11 gasification plants. The process of gasification by indirect heat exchange, has the advantage that the scrap metal is treated in a controlled atmoshpere (with temperature and oxygen content closely monitored) so that oil, water and organic contaminants are removed, without oxidation of the metal scrap being recycled. Through continuous development over the years, these gasification plants have an important feature in that via a special swirl chamber combustion process, the calorific value of the oils and organic components, removed from the scrap metal, is employed to reheat the incoming scrap metal. Under certain conditions (percentage of oil and organic material present) this renders the process largely self sufficient with regards to heating energy input.
