The provincial governments of Zuid-Holland, Brabant and Zeeland are currently incorporating biobased procurement into their procurement policies. For example, the provincial government in Zeeland, in collaboration with the Centre of Expertise Biobased Economy, has developed a method for biobased procurement. One of the results is a procurement model which businesses can use to make the added value of their biobased products clear to purchasers. The idea is for this method to be rolled out more extensively within the Biobased Delta. In addition to this the method is also going to be introduced nationally, as a way of encouraging biobased procurement throughout the Netherlands.
Government bodies can play a role in creating possibilities for testing new biobased products. One example is the biobased crash barrier used by Rijkswaterstaat [Directorate-General for Public Works and Water Management] or the noise barrier made up of lightweight fibre-reinforced concrete (elephant grass) at a provincial roadworks depot.
The government also offered biobased possibilities in the tender for the Tractaatweg Terneuzen-Gent. The provincial government of Zeeland made it compulsory for tenderers to include existing biobased infraproducts in their tender. In addition, when the tender was put out, various options were presented for biobased innovations.
The tender was eventually awarded to Boskalis. Among other things, they are going to use a biopolymer semi-paving. In addition, Boskalis is going to launch a pilot to make traffic light units from biocomposite material.
Besides creating possibilities, the government has also set up a biobased showroom at the Westkop depot, on the Grevelingendam near Bruinisse. This presentation space has been created by Rijkswaterstaat Zeelanden Delta and focuses on biobased construction in the groundwork, road and hydraulic engineering sectors.
Fifteen ecological innovations, which are contributing to a further reduction in CO2 emissions, are on display in the showroom. The innovations are accompanied by explanations in the form of information signs. These include a 60% biobased lamppost and a crash barrier made from biocomposite. In addition to this the Westkop depot has become a testing location for innovative, sustainable materials such as biobased posts, drainage pipes and building blocks.
