High prices for scrap make
the separation of refuse
scrap even more attractive.
The Scherrieble Group
has chosen a particularly
lucrative approach. The
result: absolutely pure and
high-quality iron scrap.
Clean separation of refuse scrap
Recycling in Germany is traditionally
understood as follows: householders
collect paper, glass, PET
bottles, aluminium and tin-coated steel.
These materials can be directly returned
to the production process.
The remaining general refuse contains
an unloved mix of rubbish and metal. The
first task is for this mix to be separated out.
The steel fraction, in particular, is separated

out using magnetic separators. However,
these magnetic systems inevitably also
attract large quantities of textiles, plastic
films and other materials. In that state,
this fraction cannot be sold on as scrap.
Instead, it has been common practice so
far to feed it into incineration plants at a
considerable additional payment.
Additional payment is turned into

High scrap prices have been the
motivator for the Scherrieble Group with
sites in Esslingen and Mannheim to look
for a new approach.
In their search for a suitable process
to separate the steel fraction cleanly from
the mix, the Scherrieble Group came
across the opportunities offered by the
MeWa QZ Cross-Flow Shredder. What

Gunter Scherrieble to invest were “the
system advantages of shredding, MeWa‘s
many years of experience in the field and
the suitability of the planned equipment
which had proven its worth in several test
runs”.
MeWa‘s QZ turns a former loss maker
into a profitable business. The appliance
separates the refuse scrap with 100%
accuracy. The iron steel and the smaller
proportion of non-ferrous fraction can
then be sold on the market at a profit. The
remainder is further processed to refusederived
fuels (RDFs).

task of the QZ.
