The goal of the proposed project is the development of a complete and rational solution to the problem of collection and recyle of spent automotive exhaust catalytic converters in Greece. The project comprises development of an effective collection and storage network, development of improved know-how for precious metal recovery and a detailed feasibility study for developing a complete catalyst recycle unit in Greece.

More than 500000 cars with catalytic converters are currently in use in Greece. These converters lose their activity and must be replaced every 3-5 years on the average. Catalytic converter disposal poses a serious problem due to the toxicity of some of the converter components. Furthermore the scarcity and high value of the noble metal components makes their recovery economically attractive.

The main goals of the project are:
a) Development of three prototype efficient catalyst collection networks in Athens, Thessaloniki and Patras.
b) Development of a prototype catalytic converter pretreatment unit comprising shell removal, grinding and packaging. Study of the environmental impact. The pulverised catalyst material will be treated by two CEC industries which have agreed to undertake the noble metal recovery.
c) Laboratory and pilot-scale development of a noble metal recovery unit in Greece based on an improved hydrometallurgical method.
d) Detailed feasibility study for the establishment of a complete catalyst recycle industrial unit in Greece.

The four collaborating partners (Technodynamics, University of Patras, Aristotle University of Thessaloniki and Association of Automobile Importers-Representatives) have all the necessary complementary expertise for the successful completion of the project.
