Construction company Eberhard Unternehmungen is active in various areas: demolition, remediation, recycling and civil engineering. This breadth forms the basis for Eberhard's pioneering role in the field of circular economy. The transformation process at Eberhard was not driven by efficiency—but by closing the material cycles.

Currently, the company employs more than 580 employees working at 12 locations, and boasts several additional open vacancies.

Problem

Materials from deconstruction represent Switzerland's largest waste stream: around 15 million tonnes of construction waste is generated every year.

Solution

40 years ago, the company started to develop in the direction of the circular economy, putting a stationary plant for the processing of construction waste into operation. The plants makes separating and reusing construction and demolition waste easier. Since its inception, the plants' activities have expanded. 20 years ago, Eberhard opened what is still the largest recycling centre for building materials in Switzerland, in Rümlang. Of total investment in sustainability, more than 20% is currently flowing into Eberhard. In 2021, a new recycling centre was put into operation, which can also recycle mixed rubble in addition to concrete rubble. In this way, Eberhard can increasingly close the material cycle.

Outcome

Building materials from the demolition of buildings are now practically 100% reused at Eberhard, and around 70% for the remediation of contaminated sites. 50% of the recycled building materials (secondary building materials) are used in road construction, to a large extent directly by their customers.
