RECYCLINGBIOPLASTICS Waste Framework Directive. Packaging and Packaging Waste Regulation (PPWR): Design for Recycling guidelines by January 1, 2028. Packaging is to be recyclable by January 2030. By 1 January 2038, recycled at scale: sufficient capacity for collected packaging waste to be directed to recognised waste streams through established industrial processes. Ecodesign for Sustainable Products Regulation (ESPR). This is not an exhaustive list. Additionally, European legislation on bioplastics is still developing and can be inconsistent across European Member States. Improve circularity and resource efficiency via practical application of the circular bioeconomy. Scale up effective sorting and recycling schemes for bioplastics. Increase the recycled content in new products from recycled bioplastics. Improve environmental performance across the value chain compared to fossil or biobased benchmarks. Raise social acceptance of circular biobased solutions and products. Efficient sorting is crucial for achieving high-quality recycling outputs for all plastics. Efficient sorting can be performed using existing NIR equipment at sorting and recycling facilities, provided the respective spectral libraries for those plastics are utilised. Bioplastics do not affect the recycling or recyclability of other plastic waste streams, as it has been demonstrated that they can be separated. To achieve high-quality recycling outputs, continuous improvement in sorting efficiency is necessary.
