Environmental impacts of food packaging: Is it all a matter of raw materials?
The packaging sector and the environmental impacts stemming from its various materials and applications are currently at the forefront of scientific and political debate. To estimate the environmental impacts associated with raw materials and identify the role of industrial processes, this study presents a cradle-to-grave Life Cycle Assessment applied to two distinct packaging formulations for chocolate bars, namely oriented polypropylene-based and paper-based packaging. The product systems related to the two alternatives were compared by focusing on the contribution of each resource input and emission of the production phase, to identify respective environmental trade-offs and potentials for future improvements throughout the life cycle. Our study also proposes a laboratory-based approach to develop robust assumptions concerning the modeling of end-of-life material treatment and provide support to decision-making toward environmentally sustainable waste management practices. From the outcomes, a relative preference emerges for paper-based packaging, from a minimum of 10 to a maximum of 16 out of 18 environmental categories, depending on the evaluated scenario. The hotspot analysis highlighted a significant influence of the processing phases, with raw materials being generally characterized by lower percentage contributions to the final impact. In conclusion, the findings underscore the importance of considering the entire life cycle when assessing packaging sustainability. Moreover, the proposed laboratory approach offers valuable insights for policymakers and industry stakeholders to optimize end-of-life strategies and minimize the overall environmental footprint of packaging materials.
期刊介绍:
Sustainable production and consumption refers to the production and utilization of goods and services in a way that benefits society, is economically viable, and has minimal environmental impact throughout its entire lifespan. Our journal is dedicated to publishing top-notch interdisciplinary research and practical studies in this emerging field. We take a distinctive approach by examining the interplay between technology, consumption patterns, and policy to identify sustainable solutions for both production and consumption systems.
