A WORLD LEADER IN PLANT CHEMISTRY AND A COMPANY OF THE FIRMENICH GROUP, DRT HAS BEEN CREATING AND PRODUCING BIO-SOURCED INGREDIENTS SINCE 1932 TO HELP DEVELOPING SUSTAINABLE CONSTRUCTION.
Recognized and proven within the industry, DRT’s pine-based ingredients are especially appreciated for asphalt, bitumen or concrete applications, combining a renewable approach with optimal technical properties.
DERTOPHALT™ is a plant-based binder, obtained by distilling co-products of the pulp & paper industry. For road building, DERTOPHALT™ offers a high performance and sustainable solution to drastically reduce the environmental impact of construction. Mainly composed of rosin and fatty acids and 100% natural, its binding performance makes it the perfect partner to produce asphalts with a higher renewable content. It paves the way for sustainable roads, cycle lanes, curbs, parking lots and much more.
Going further, DERTOPHALT™ is also the perfect additive to recycle asphalt on site. Actually, processes have been developed for which old degraded bituminous pavements are mixed with DERTOPHALT™ in mobile facilities and directly applied again, leading to a brand-new road with even more resistant asphalt. As they are rejuvenated on site, the old road components no longer require to be carried around by trucks from the production site to the construction site which saves transport emissions and costs while contributing to an even greater environmentally friendly approach!
