Can fossil-based plastics be completely substituted by biobased bioplastics?

Today, there is pretty much nothing that bioplastics cannot do. For practically every conventional plastic material and application, there is a bioplastic alternative available that offers the same or, in some cases, even better properties and functionalities. The main challenge faced by the bioplastics industry is not of technical nature but the lack of effective policy measures or regulatory incentives to encourage a full-scale market entry. According to a PRO BIP study conducted by the University of Utrecht already in 2009, bioplastics could technically substitute around 85 percent of conventional plastics. To make all plastics from biobased materials, however, is not a realistic short- or mid-term development.
