Sustainable products & services

When bringing out new product innovations, Villiger pursues the aim of delivering sustainable solutions. That is why Villiger makes sure it uses recyclable raw materials in the production process and protects the environment by designing its products to be long-lasting. 

Containers from sustainable manufacturing


All Villiger products are made from recyclable materials, the majority just from steel. The modular design ensures that resources are used responsibly, paving the way for significant reductions in transport.  


Reducing CO2 emissions


The Quadromat disposal system allows up to 20 m³ of compacted waste - equivalent to more than 100 traditional wheeled containers - to be collected in a single system.
Waste collection trips can be reduced by over 25% per Quadromat system.

Zinc recovery

Villiger's modular, screw-on systems enable the recovery of zinc. it is obtained from the galvanized steel used for individual parts, increasing the value of the scrap metal. 
Villiger hands over all of its scrap metal to Elektrozinn AG, which carries out the zinc recovery. 

The tinning process is an important part of the raw material cycle, e. g. in the processing of cans.
In the following we show you the zinc extraction in 5 steps (source:

Step 1:
Cans are collected and taken to a processing centre (e. g. electric tin).

Step 2: 
The aggregate material consisting of tinplate and aluminium is separated from each other by means of magnetic separators. The tinplate is transported to the electric tin by rail or truck. This prepares it mechanically for tinning by means of a rotary mill.

Step 3: 
The prepared tinplate scrap is filled into iron baskets and electrolytically de-tinning with direct current. The baskets are immersed in electrolysis solution (6% caustic soda). The tin on the tin plate is oxidized, dissolved and then deposited at the negative cathode.

Step 4: 
The tin recovered from the cathode is then pressed into a cake and delivered to a tin factory for further processing, where it is refined into pure tin.

Step 5: 
After the tinning process, the remaining black plate is washed with water and pressed into packages. The raw material obtained in this way is delivered to the Swiss steel industry for further processing.
