Author comment: The evolution of life cycle assessment in the food and beverage industry: A review — R1/PR5

Life cycle assessment (LCA) has been progressively used as an tool to quantify and compare environmental impacts in the food and beverage industry. This paper reviews LCAs on single-use food and beverage plastic products from January 2000 to June 2022. Studies are also analysed in the context of marine plastic pollution which is a global concern. A total of 91 studies were reviewed with 44% conducted for the European region. Findings suggest that most studies follow the traditional approach and structure of LCA with some studies focusing on global warming potential and others incorporating aspects such as life cycle costs and mass-based indicators. A total of 62% of reviewed studies had a cradle-to-grave scope. LCA studies can be influenced by public discourse, for example, the rising concern surrounding plastic marine pollution. From 2019, additional environmental indicators have been included in LCAs wherein the product is a major contributor to pollution. To date, six studies have proposed marine litter indicators. In future years, we can expect further development of life cycle impact assessment methods to reflect concerns in the public discourse. This includes methodologies for assessing circularity or plastic pollution. Furthermore, product foci will continue to follow popular trends.
