A Conceptual Framework of the Sustainability Challenges Experienced during the Life Cycle of Biobased Packaging Products

Biobased packaging products are framed as products that have environmental value. They are promoted by many institutions and companies as a way of addressing climate change challenges by decreasing carbon footprints and providing alternatives for the fossil fuel-based economy. The use of biobased packaging products has started to become widespread, and they are increasingly commercially available. Despite the acknowledged benefits of such products, there are several challenges associated with the use of them. This paper provides a state-of-the-art review of biobased packaging products and presents a conceptual framework of the sustainability challenges experienced over their life cycles. The framework categorizes the identified challenges by their environmental, social, and economic impact, as well in terms of the different life cycle stages, from beginning of life to middle of life to end of life. In addition to increasing the understanding of the challenges associated with biobased packaging materials and their use, the proposed framework benefits the analysis of these challenges in different organizations, the identification of potential greenwashing, and the development of mitigation strategies to overcome the challenges. Furthermore, this study reveals gaps in the literature to be considered in future research into biobased packaging products.
