Bauma 2022 – sustainable asphalt production

Bauma 2022 innovations: sustainable technologies in asphalt production

Benninghoven offers sustainable and economical technologies for reducing the carbon footprint

Benninghoven will be showing at Bauma 2022 how owners of asphalt mixing plants can meet the challenges of our time. The focus is on increasing efficiency and substantially reducing emissions that are damaging to the environment. When it comes to the emission of substances such as CO2 and Ctot (total carbons), asphalt mixing plants offer great savings potentials that should be fully utilised.

At Benninghoven, the mission of “sustainability in asphalt production” comprises several central elements. These are: re-use of asphalt, correct storage of virgin mineral and recycling material, use of temperature-reduced asphalt, electrification of bitumen tanks and use of renewable energies, i.e. the fuels of the future.

Reducing the CO2 footprint

Benninghoven solutions provide more energy efficiency and reduce the carbon footprint, making greenhouse gas savings of up to 54 % CO2 per year possible.

Hot and cold recycling feed systems

Benninghoven offers a wide range of “hot and cold” recycling feed systems for reusing reclaimed asphalt, obtained with Wirtgen cold milling machines, among other things. The recycling systems can also be retrofitted on existing asphalt mixing plants.

Roofs for dry storage

Roofs for dry storage of virgin mineral and recycling material save a large amount of fuel and therefore CO2 during drying and heating of the material.

High potential for saving energy

Reduced-temperature asphalt offers a high potential for saving energy and CO2: The key contribution comes from the production, i.e. from a Benninghoven asphalt mixing plant with the appropriate technologies.

Electrically heated tanks

Electrically heated tanks with optimum energy insulation from Benninghoven make bitumen storage efficient with zero local emissions.

Use of renewable fuels

Using renewable fuels today: Benninghoven EVO JET burners can also burn biomass-to-liquid fuel (BtL) or wood dust.
