Application of standards, certification schemes and labels has positive long-term effects on the overall development of the European bio-based product market. Good product information that presents correct claims to industry and public procurers is vital for the usage of these new products. Ensuring the sustainable sourcing of raw materials and the effective bio-content are important additional steps for public confidence. Clear indication of their (comparative) functionality and the optimal possible end-of-life options, needs to underline their positive impact compared to the regular products. Finally, public acceptance comes with clear and harmonized labels on products and packages. The Open-Bio project has assessed test methods, labels and available product information regarding bio-based products. They have developed determination techniques on direct and indirect biomass content and biodegradability tests. Practical solutions for stakeholders, lab and field tests or capability of a product being recycled or digested in a gasifier have also been studied. Some results have been introduced in European standards. In order to optimize market exposure a optimized product information list has been developed, which has been assesses via a database on bio-based products. Socio-economic research on what consumers and (public) procurers want to know about bio-based products via a set of target groups forms the basis of the questions asked for filling the database. This article explains some of the background of the project and zooms in on the work on the product information database and the social acceptance.
