GMH Recycling GmbH


In accordance with the Closed Substance Cycle Waste Management Act, every company is legally bound to avoid or reduce waste generation. GMH Recycling GmbH continually develops its recycling facilities to comply with these legal stipulations and, where possible, to go beyond these obligations.

Waste water

If hydrocarbons such as oils or fuels are washed away with rain water, this waste water is treated in separating facilities consisting of a sludge trap, a petrol/oil separator and a coalescence separator. The treated waste water can then be directed to the drain. Dewatering of chip areas takes place in our emulsion splitting plant. The treated waste water is then directed to the municipal sewage network.

All facilities as well as the related sewage network are inspected regularly with regard to leaks. Additionally, our waste water is monitored at regular intervals by an independent test laboratory. ​

Hazardous substances

In order to reduce the polluting potential of the hazardous substances used, we strive to use alternative substances. All hazardous substances used are recorded in a database and corresponding safety data sheets are available. Employees are well-trained in the handling of these substances.


The metal recycling economy has committed itself to exclude scrap and commercial items which show radioactivity above the natural inherent radiation of the metal from the economic cycle.

For this reason all scrap is inspected for radiological abnormality prior to acceptance and again prior to leaving the sites. In the event of alarm, a clearly defined process is implemented to prevent any danger to humans and the environment.

Scrap and chip storage

Scrap is stored in areas sealed with concrete and HDPE film. This prevents pollution of the soil and groundwater from any contaminating substances associated with the product. The construction of storage areas was monitored by sworn experts, and the documented results submitted to the regulatory authorities. Swarf and grinding sludge are contaminated with water-endangering cutting oils and drilling emulsions. These materials are therefore stored on suitably reinforced surfaces which are connected to emulsion splitting plants. ​
