Abstract:The packaging for eggs is mostly disposable with great consumption. Its main materials are generally pulp molding and polyvinyl chloride, etc. Based on life cycle assessment (LCA) methodology, the environmental impacts of egg packaging with two different kinds of materials were built models and evaluated by using eFootprint software and database. The functional unit was based on a single egg packaging which could hold 30 eggs with the size of 292 mm in length, 245 mm in width and 35 mm in height. The setting of system boundary included the main processes of the egg packaging, such as packaging material processing, pressing, die cutting and packaging products etc. The results showed that the evaluation objects contributed a lot to GWP, WU and PED. The environmental impacts of pulp molded tray for eggs were 90 g, 0.17 kg, 1.3 MJ, while the polyvinyl chloride tray for eggs were 720 g, 4.27 kg, 9.84 MJ. According to the evaluation results, the influence on the environment from the pulp molded tray for eggs was smaller than that of the polyvinyl chloride tray, therefore, pulp molded tray for eggs should be preferred. On the premise of ensuring products quality, it was suggested to give priority to the materials and additives which had little impacts on the environment for product design and production, and reduce the impacts on the environment of packaging products by selecting PVC materials with higher gram weight and modifying the structure design of egg tray.
