Biobased guardrails

Rijkswaterstaat has launched a project for a biobased alternative to conventional guardrails.


In The Netherlands, guardrails are mainly made of galvanized steel. Galvanization is a method of applying a protective zinc coating to steel or iron for industrial use, in order to prevent rusting. While zinc is a natural substance and is necessary for human health, too much of element can be harmful to human health. The zinc particles sink into the soil. When farmers grow their crops, the zinc is then leeched into the food supply and again moves further up the food chain through consumption.


Rijkswaterstaat is responsible for the design, construction, management and maintenance of the main infrastructure facilities in the Netherlands. Together with the BBCT consortium (Biobased Composites Technologies) they have launched this project as a test at greencare parking Westkop. During this phase, various tests will be done to comply to the national safety requirements for guardrails along Dutch highways.
