A road construction company from Altomünster in Germany demonstrates how a little brainstorming can turn into a lighthouse project.Christian Schweiger had the idea to run his asphalt mixing plant in Aichach with regenerative energy and achieve virtually carbon-neutral production in the future. To implement this bold plan, he contacted Benninghoven – the first point of contact for sustainable asphalt production. Around four years later, in September 2023, the first virtually carbon-neutral asphalt mixing plant has started operating, fuelled with wood dust instead of heating oil.
