About us Thermal treatment of tar-containing asphalt Products Services Contact NL EN D Roofing Bituminous roofing felt In addition to tar-containing asphalt, REKO also processes tar- and bituminous roofing to a high grade. Tar- and bituminous roofing felt often contains polycyclic aromatic hydrocarbons (PAHs). In the thermal treatment plant, these PAHs are completely destroyed by high-temperature incineration. The hot flue gases released in this incineration process are used to generate steam and electricity, just as they are when processing tar-containing asphalt, and are then cleaned in the flue gas cleaning system. The energy content in the tar- and bituminous roofing also provides a significant saving in the consumption of natural gas required for the thermal cleaning of asphalt. The recovery of energy and its beneficial use leads to huge reductions in CO2 emissions.

About us Thermal treatment of tar-containing asphalt Products Services Contact NL EN D Gypsum gypsum Within our thermal treatment process, much attention is paid to the optimal cleaning of the released flue gases. The goals we have set for ourselves are that no waste products are created during the treatment process and that we comfortably comply with the applicable requirements. Tar-containing asphalt contains a lot of sulphur. This sulphur burns and forms sulphur oxide. To remove this sulphur oxide, REKO opted for a so-called wet flue gas scrubber, in which the sulphur oxide is converted into gypsum using lime. For some time now, REKO has been supplying the gypsum produced to the gypsum processing industry, which uses it to make plasterboard and anhydrite. These products are widely used in construction for new buildings and renovations. Thus, this flow is 100% reused too.
