Reducing Emissions

The VOC Reduction Device (VRD) is a standalone solution that can be added to any asphalt plant to filter fumes. VRD reduces VOCs by up to 70%, providing significant emission reductions without the need for continuous operation. The system features self-cleaning technology, eliminating the need for filter replacements. This ensures optimal plant uptime and reduced maintenance costs.

The Blue Smoke Treatment (BST) system captures emissions at the end of the asphalt production process, particularly during loading. BST captures, reroutes, and reuses the smoke in the combustion chamber, reducing visible emissions and lowering costs. The system features a multi-stage filtration process that removes oily particles and recycles condensed oil, ensuring high efficiency and minimal environmental impact.

The Ammann baghouse filter reduces exhaust particulates to well below the 10mg/Nm³ PM benchmark. This high-efficiency filter features proprietary rotor step mechanisms that gently clean the filter bags, reducing wear compared to pulse jet systems. The system provides 99.9% filtration efficiency, ensuring compliance with strict emission standards. Minimal moving parts reduce maintenance and improve reliability.

The comprehensive approach to reducing the environmental impact of asphalt production includes noise reduction, dust suppression, and odour control. Advanced technologies ensure compliance with environmental regulations and promote sustainability in every aspect of the production process. From quiet burners and stack silencers to efficient dust and odour control systems, Ammann provides solutions that make asphalt plants more environmentally friendly.
