Abstract
The foundry produced 12400Â t of wastes in year 2002, made of the following materials: several types of muds and dusts coming from dust abatement plants (28.7%), furnace and ladle slags (21%), aluminium shavings (21%), machinery emulsions (9.8%), exhaust moulds and cores (4.7%), various materials packing (4%), refractory material from furnaces (3.5%), saline solutions containing phosphates (3.5%), wastewater treatment mud (1.6%) and other materials (1.7%). Among these wastes only slags and aluminium shavings are sold for a recycle outside the foundry; the other materials, making about 8200Â t/year, are landfilled. After a careful study of the foundry production cycle, several waste materials have been studied to evaluate their reuse/recycle possibilities. Considering the obtained results the authors are able to hypothesize a reuse inside the foundry of the dusts and a kind of mud (about 1900Â t/year of wastes) and a recycle outside the foundry, as inert material, of the exhaust moulds and cores and another kind of mud.
