Use of bio-based products and innovation procurement by Dutch province for road works

Located in the south-west of the Netherlands, the Province of Zeeland’s government recently undertook an innovation procurement to commission a public works contract to widen a major road in the Netherlands (N62 Tractaatweg) - from one to two lanes, and to build four new viaducts. To take into account the challenges of purchasing bio-based solutions (such as geotextiles, biodegradable underground tree anchoring systems, etc), as these are not widely available on the mainstream market, Zeeland carried out a process of competitive dialogue.

This type of approach enabled them and potential contractors’ greatest flexibility in meeting their needs. During the dialogue process, the companies who responded to the initial expression of interest were asked to deliver two specific bio-based products, plus one or more products from a pre-identified list of market-ready bio-based options for on-site piloting.

The company who was awarded the contract chose one of each of the proposed solutions for the products’ application and piloting. The bio-based products were applied to the road construction itself for construction of the road’s under-layer. Piloting of was undertaken for the installation of cabinets for traffic light installations made from bio-based composites.

A case study of the Province of Zeeland’s experience has been published as part of the EU-funded InnProBio project. The case study is available here.
