Asphalt production: Innovative and Sustainable Solutions

Efficient and Environmentally Friendly Asphalt Production

As an asphalt producer, you are confronted with numerous challenges, such as dust emissions, bitumen fumes and odour pollution. Harmful volatile organic compounds (VOCs), including benzene, and polycyclic aromatic hydrocarbons (PAHs) cause nuisance. The increased demand for circular asphalt makes the situation even more complex. Moreover, it is often not easy to integrate the necessary downstream techniques into an existing asphalt plant. At Lybover, we understand these challenges and come up with innovative customised solutions, from a simple replacement to a complete upgrade.

Why Invest in the Modernisation of Your Air Treatment System?

Comply With Increasingly Strict Emission Standards

Legislation regarding emissions of dust, VOCs and fragrances is becoming increasingly strict and inspections are more frequent. Our experts, supported by a technologist, are familiar with the legislation and follow it closely, so that your installation always meets the latest standards with the best available technology. This also applies to increased use of recycled asphalt.

Ensure You Comply in Time
Create a Healthy (Working) Environment

In addition to complying with stricter legislation, investing in a modern asphalt plant is essential for the protection of employees and local residents. Limiting dust and odour nuisance is not only important to keep the neighbours happy, but also to ensure a healthy and pleasant workplace for one’s own employees.

For a Pleasant and Healthy Workplace
Choose Technology That Is Truly Sustainable

Take all parameters into account. You will only achieve a truly sustainable result by making the right choice or the right combination of technologies and by ensuring they are correctly dimensioned. Look at both the long and short term, whether you are working in phases or going for a full upgrade. Choose a technology that suits your process and your site, but also your capex/opex.

Together We Determine Your Business Case
Work Safely, Efficiently and Ergonomically

Adapting your plant on a limited surface area is not easy. That is why we design and draw in 3D. We walk through the design together in Virtual Reality. We take all movements on the site into account and thus create a safe, efficient, and ergonomic working environment.

A Design Completely Tailored to Your Needs
Reliable Operations

It is not only crucial that your asphalt plant remains operational, but also that the air treatment is functioning optimally. That is why we offer you extensive support during commissioning and preventive maintenance to extend the lifespan of your installation. Our service engineers provide a detailed air treatment report after each intervention.

Have Your Installation Checked Periodically
Look At the Bigger Picture

There is also often great potential for efficiency gains in the supply and distribution of raw materials. We would be happy to sit down with you to see how we can improve these processes as well. With our extensive experience in sorting techniques, we can also advise you on how to monitor the quality of recycled content at the input level, as well as how to recycle asphalt mixtures.

Optimise Your Supporting Processes

What Will We Be Covering on Your Site?

At Lybover, we tackle problems at the source. With our targeted and well-considered approach, we identify all emission sources and choose the appropriate filtering techniques for the various process steps. This is how we reduce the environmental impact and improve public perception. We take a broad view and can also monitor the supply and disposal of raw materials and the quality of recycled content.

The drying and heating of raw materials takes place in a drying drum. This involves both new granulates as well as asphalt granulate. In the latter, the old bitumen is re-liquefied, resulting in specific emissions:

  • High temperatures
  • High humidity
  • Dust
  • Odour, benzene, VOCs and PAHs

After the dried granulates have been weighed and measured, they are combined in the mixer and the bitumen and fillers are added. The asphalt mixture is stored as a final product in the final silos awaiting the loading of the trucks. Here we are confronted with:

  • Medium temperatures
  • Bitumen vapours
  • Dust
  • Odour, VOCs and PAHs

When filling the storage tanks for bitumen, the incoming bitumen displaces the same volume of air from the tank. This displaced air has been in contact with bitumen for a long time and thus causes undesirable emissions. At this point we encounter:

  • Concentrated bitumen vapour
  • Odour, VOCs and PAHs

We take a broad view of the asphalt production process and also examine the peripheral processes. We are happy to look at how we can optimise these further. This includes:

  • Supply and removal of raw materials
  • Monitoring the input quality of recycled content
  • Recycling asphalt mixes

Customisation With a Broad Perspective

Each installation is given a custom-made filter system, where design and dimensioning are specifically calculated and designed based on the amount of air flow, the amount of dust, the development of smoke, odour and VOC concentrations and other specific requirements for your site.

  1. In the first phase, we will work together to identify the problematic emission points.

  2. After that, we will use proven ventilation models to determine the best ventilation technique. This way, we can avoid diffuse emissions.

  3. To work as accurately as possible, we first make a 3D scan of your plant and the surrounding area.

  4. Based on this, we create a three-dimensional design. The chosen ventilation model can be tested against this design with a CFD simulation.

  5. In our own production department, we build customised components that we combine with high-end components from exclusive technology partners.

  6. A two-stage filtering system first removes the dust and bitumen fumes using a suitable filtering technique. Then an activated carbon filter removes the remaining odours and (toxic) VOCs. Depending on the process, an intermediate filter can be placed to provide the activated carbon filter with extra protection.

  7. Our assembly team will take care of the installation. We use a total station to accurately and efficiently mark all anchoring points.

  8. After delivery, it is time to put your new installation into operation. Our specialists will take care of the commissioning and training of your operators.

  9. You can also always count on Lybover for maintenance and service, both reactive and preventive. Relieve the burden on your own employees and receive clear and detailed reports.
