The environment means life, and we take care of it.
Since July 1, 2005, the disposal of untreated waste in landfills has been prohibited in Germany. For this reason, a large proportion of the municipal and commercial waste generated is sent to thermal recycling plants. In addition to the energy potential that these materials offer, the resulting bottom ash and boiler ash also contain valuable substances.
In 2020, around 6 million tons of fresh bottom ash were produced in Germany. This goes through various processing stages at our sites, resulting in different fractions. One of these is recovered metals, including iron, copper and aluminum.
On average, these make up around 10% of the slag produced.
These recovered metals can now be fed directly into the economic cycle. This type of recycling protects the environment to a high degree, as classic metal extraction is an energy-intensive process.
Our contribution to climate protection
The STORK Group extracts around 240 tons of metals every day. This corresponds to an annual output of almost 57,240 tons.
We therefore achieveCO2 equivalents of 172,444 tons per year.
For comparison:
- A beech tree has to grow for around 80 years in order to utilize one ton ofCO2.
- The average German citizen emits around 8.9 tons ofCO2 per year.
