The paper presents a semi-industrial reactor designed for utilisation of waste moulds and cores made of thermosetting moulding sands by microwave incinerating. It was found that a possibility exists of effective incinerating residues of this kind waste cores or moulds left after casting. The research evidences that the apparatus permits effective control of the applied microwave heating process. Preliminary tests of microwave heating indicated that incinerating waste moulds and cores made of industrially used moulding sands based on phenolic-formaldehyde resins is an effective method of their utilization. Application of microwave heating for incinerating waste moulds and cores containing synthetic resins as binders guarantees significant and measurable economical benefits resulting from reduced process time.
