We, at Grupo LYRSA, are pioneers on the ecological treatment of End-of-Life Vehicles (ELV) in Spain: we were signatories of the General Agreement on ELV Recycling and foundational member of the Integral System for the Recycling of ELV waste (SIGRAUTO).
The first step on vehicle recycling takes place at the Authorized Treatment Centers (CAT), where the official deregistration at the DGT (Spain's Traffic General Office) is processed, the vehicle is decontaminated (extract all the dangerous liquids like petrol, oil or brake liquid) and all the parts that may be used again as second hand auto parts are extracted.
Once decontaminated, the vehicle is packed with a mobile press truck to ease the transport to one of the six shredder plants that Grupo Lyrsa operates in Madrid (Reyfra), Sevilla (Lyrsa) and Álava (Lyrsa).
The shredding process consists on the grinding of the ELV and the classification of its components: the light fraction by means of aspiration and the ferrous fraction by means of magnetic techniques. Apart from the ferrous fraction (approximately 70% of the total weight of the ELV) and the light fraction, we also obtain a fraction of mixed non ferrous metals and plastics that have to be separated in a later process to obtain homogeneous materials.
For this subsequent separation, we use flotation or heavy media and also Eddy-currents. Mefragsa is the Grupo LYRSA Company specialized on this separation, to obtain the aluminum fraction of this mixed metals that is melted in this same plant to obtain pure aluminum ingots of great purity.
