The need to tackle the current environmental impact
of plastics is driving the development of new bio-based materials. Although these bioplastics
offer carbon footprint
reductions, their role in a more sustainable economy is still unclear. Herein, a systematic review was performed to understand the impact of producing bioplastics. This information was used to perform a life cycle assessment
considering different end-of-life scenarios. Then a Smart Use of Materials based on the assumption of only using certain materials in targeted applications was proposed. It was found that the dedicated use of bio-polyethylene terephthalate for packaging and polylactic acid for textiles can offer a carbon footprint reduction of up to 67% and 80% respectively. Therefore, we present a major opportunity to decarbonize our society using current technologies and supply chains. This concept contributes to building a society that understands the place of bio-based materials and addresses pollution from a material selection perspective.
