Biobased traffic signs

During a 3-year project funded by InfraSweden, biobased traffic signs were designed and tested outdoors. The signs were made of LigniSet® resin and reinforced with fibers and fillers. Three demonstrators showed good reflective foil adhesion and outdoor durability for 6 months, facing a tough winter in Karlstad. The lignin used in the signs was provided by Södra, the signs were produced by NPSP, a Dutch biocomposites specialist, and installed by Provia AB, a leading distributor of temporary road equipment in Sweden, with the supervision of Trafikverket.

A Eurostars-funded project in collaboration with NPSP is ongoing to further explore LigniSet®-based bulk composites for a wider variety of road equipment, and the development of fully bio-based traffic signs is set to continue through new pending project applications.

Focusing on temporary then permanent signs at first, we are striving to soon bring fully biobased traffic signs to the Swedish and European markets as our first commercial product!
