A holistic cradle-to-cradle assessment Of liquid food packaging

Abstract

This research investigates the ecological impact of the production processes of two packaging types in malt beverage marketing: plastic bottles and aluminum cans. The cradle-to-cradle life cycle assessment facilitates the analysis of carbon dioxide emissions and energy consumption associated with each packaging alternative, thereby allowing for comparisons rooted in sustainability principles. The findings suggest that polyethylene terephthalate (PET), commonly utilized in food packaging, possesses a detrimental environmental profile attributable to its substantial energy requirements and considerable carbon emissions associated with its production and processing phases. Conversely, while polypropylene, often utilized in plastic production bottle caps, exhibits a lower environmental impact than PET, it nevertheless fails to exceed the intrinsic sustainability benefits associated with aluminum. Aluminum displays considerable environmental advantages, characterized by reduced carbon emissions and energy requirements throughout the production process. Its elevated recyclability facilitates reintegration into the production cycle without compromising its physical and chemical properties, which is a crucial element in reducing environmental impact. The ongoing usability of materials diminishes the necessity for virgin raw materials, consequently conserving natural resources and reducing the generation of solid waste. The available evidence suggests that prioritizing aluminum cans represents a viable approach to improving sustainability in food packaging, especially within the malt beverage sector, to reduce negative environmental impacts. Similarly, the establishment of public policies that prioritize ecological education and sustainability is critical for promoting responsible consumption practices.
