Situation Task
Wiederkehr Recycling AG dates back to the foundation of the
company by Xaver Wiederkehr in 1959. Today the Wieder-
kehr Recycling group has 103 employees at its headquarters in
Waltenschwil, Switzerland. A further 170 are employed in sub-
sidiaries in Germany, China, Japan and Vietnam.
Wiederkehr Recycling AG is one of the leading companies in
recycling scrap metal and plastics. It processes approximately
120,000 to 150,000 tonnes of material each year. The scrap met-
al comes from all over Europe. To process this material Wieder-
kehr uses a 3,000 horse power shredder and a scrap shearing
machine. The material prepared in Waltenschwil is supplied to
steel works in Switzerland, Germany and Italy and then trans-
ported by road and rail. Every day up to 1,000 tonnes of scrap
arrives at the site in eastern Switzerland.
Several Liebherr material handlers of various sizes with mo-
bile and stationary undercarriages are used to load and unload
trucks and wagons, for sorting and stockpiling scrap and for
loading the shredder and shearing machine. At peak times, up
to 1,000 tonnes of scrap and recyclable material is delivered to
the site in Waltenschwil.
A lorry loaded with scrap rolls up every 10 minutes and unloads
material. The previous handling concept was based on a rail-
bound portal solution. Due to the increased space requirements
associated with this and due to the redevelopment of the site an
electric stationary concept was chosen.
