Paper vs Plastic: A comparative Life Cycle Assessment (LCA) of two flower packaging solutions

Abstract: The concept of sustainability is currently a prominent topic of discussion within the field of packaging. In the context of numerous product manufacturing enterprises, the integration of sustainability principles into their operational framework is often perceptible to external observers solely through the packaging of the final product. In addition to the established criteria, fundamental concepts and principles, the predominant discourse surrounding the pursuit of sustainable packaging goals primarily revolves around the specific models and practices implemented by the industry. Growing environmental concerns from industry and consumers have driven the development of innovative bio-based materials as alternatives to fossil-derived plastic polymers for packaging applications. This thesis project is in collaboration with the Swedish-Finnish company, Stora Enso Oyj; a paper mill company specialized in packaging, biomaterials, wooden construction and paper solutions, made by renewable materials, such as wood and biomass. The study involves the execution of a comparative Life Cycle Assessment (LCA) to evaluate two distinct packaging solutions. The EcoFlowerBox (EFLB), a packaging solution developed by Stora Enso, is specifically designed to cater to the needs of the floral industry. It serves as an alternative to the conventional flower bucket, fulfilling the essential functions of flower storage and transportation. The materials that were compared in the study are corrugated board and plastic, respectively. The main objective of the study was to determine the most environmentally sustainable option based on the greenhouse gas emissions generated throughout their entire life cycle. In addition to the criterion related to material composition, the ecological durability of the products was assessed by considering their end-of-life treatment and potential.  The assessment methodology discussed in this study covers the complete life cycle of the products being examined. This includes the extraction of raw materials, the manufacturing and utilization processes, and the eventual end-of-life stage.  The research findings indicate that the EcoFlowerBox (EFLB), produced by Stora Enso, exhibits a carbon footprint that is 29% lower compared to the PP bucket in the baseline scenario. This suggests that, from a climate standpoint, the EFLB functions as a more environmentally advantageous packaging solution, in terms of greenhouse gas (GHG) emissions, in comparison to the PP bucket. Additionally, the study identified that the recycling rates and the weight of the PP bucket are crucial factors that exert a substantial impact on the study's outcomes. The results underscore the significance of addressing these areas of concern in order to improve the environmental performance of the EFLB when compared to other PP buckets, and to attain more sustainable packaging solutions for flowers.
