Lingenheld invests in green technology
The Alsace-based Groupe Lingenheld has demonstrated its commitment to sustainability in many different ways. As one example, the company has invested in a fleet of electric vehicles for its employees and has used tree-planting to balance out all of its CO₂ footprint. Alongside road-building, Lingenheld also offers a number of specialized services, such as the decontamination of buildings and terrain polluted with toxic substances.
The company is also a pioneer in the asphalt production segment, where it is now investing in eco-friendly recycling technology from Benninghoven. Lingenheld has recently acquired a type TBA 4000 asphalt mixing plant with a hot-gas generator. Offering market-leading recycling technology, this plant converts up to 90 + X% of reclaimed asphalt into new asphaltic mixture while simultaneously reducing emissions – especially total carbon (TC). To ensure the plant also meets stringent requirements for low-dust operation, a high-performance Benninghoven filter system with a capacity of 90,000 Nm³/h also extracts most of the dust produced.
The TBA 4000 also offers a huge performance boost. The 320 t of asphalt that Lingenheld can now produce and deliver per hour represents a doubling of the old plant’s capacity. Other components have been expanded accordingly, with a hot bin section of 130 t, a loading silo of 341 t in four bins (as well as 13 t of direct loading), which means that Lingenheld can store and process both large and small quantities of asphalt. A wide choice of feed systems ensures that many different recipes can be implemented. Additives, granulates, and adhesives can be dosed directly into the mixing process. All of which means that the target of 100,000 t of various high-quality asphaltic mixtures per year is easily achievable.
