The leading, patented recycling technology from BENNINGHOVEN allows plant owners to produce asphaltic mixtures from 100 % reclaimed asphalt. At the same time, the asphalt mixing plant meets the stringent official limits for air quality control, including the German TA-Luft regulation.
Providing asphalt in the required quality and quantity at the right time is already a challenging task that requires perfectly coordinated plant components. When maximum recycling content in asphalt production with minimum emissions are added to the equation, the BENNINGHOVEN hot-gas generator becomes indispensable.
BENNINGHOVEN offers integration of the hot feed system as new plants as well as a Retrofit solution for existing asphalt mixing plants.

While the recycling material containing bitumen would “burn” with direct firing or undergo an adverse change to its properties, the hot gas generator heats it only indirectly, gently bringing it up to its optimum application temperature.
At the same time, the process reduces emissions – for example because the total carbons in the exhaust flow are largely burnt off.
The recycling material is heated to the optimum processing temperature of 160 °C. All emissions are kept in the standard range and the contained bitumen is not burnt.
The hot gas generator technology allows fresh asphaltic mixtures to consist of 100 % reclaimed asphalt.
Working more efficiently with sustainable and economical technologies is the challenge of today and tomorrow. Benninghoven offers a variety of innovative solutions for increasing sustainability in asphalt production.
