Replaced oil filters from cars and trucks are classified as special waste worldwide. However, they consist of some 60% metals (mainly iron). The oil accounts for around 20% of the material mixture. The actual paper filter, rubber sleeves, and other plastic parts make up the remainder. ANDRITZ MeWa implemented the first oil filter recycling plant in Europe back in 1995. This cutting-edge technology is now found worldwide.

The objective of oil filter recycling is to recover clean fractions of ferrous metals and oil for reselling. First, extraneous material has to be removed from the infeed. After this, the oil filters are shredded with the universal granulator UG. Iron, oil, and paper are separated into clean fractions. The oil is pumped out and stored separately.

Throughput of the plant: 2 t/h (depends on the size of the machine and the material mix)

Results
Ferrous metals (approx. 44%)
Paper (approx. 40%)
Oil (approx. 16%)
