The SOCIÉTÉ ANONYME DE PRODUITS ASPHALTIQUES, in short SAPA, is a subsidiary of Implenia, Switzerland’s biggest construction and construction services company, and a valued customer of the Wirtgen Group. SAPA supplies asphalt mixes of all kinds not only to its parent company, but also to other customers, mainly for use in smaller and medium-scale road construction projects.
The Swiss take sustainability and energy-efficiency very seriously. In view of this, the company planned the replacement of the old facilities at its headquarters in Satigny, not far from Geneva, with a new, next-generation asphalt mixing plant.
