Bio-based traffic signs for a sustainable traffic environment

Purpose and goal

The aim of the project is to contribute to a climate-neutral transport infrastructure by reducing energy consumption and carbon dioxide emissions that arise from the use of current traffic signs by introducing new and innovative products based on renewable raw materials. Through the project, a further purpose of the study is to verify a new value chain that uses residual products from the Swedish pulp industry to manufacture traffic signs.

Expected results and effects

During the project, demo products of renewable traffic signs will be produced and evaluated in an operational environment to evaluate the products´ mechanical performance compared to the commercial requirements. Results of the project are expected to be presented in the form of a possible implementation plan and a compilation of the feasibility study carried out. The results will further present the value of substituting fossil materials in traffic signs for a new lignin-based material with regards to durability, performance and economic feasibility.

Planned approach and implementation

The project is divided in 5 work packages: Recipe formulation and evaluation on a laboratory scale (AP1), Upscaling and production of demo products (AP2), Evaluation (AP3), Verification and tests in an operational environment (AP4), Compilation of feasibility and implementation plan (AP5).
