Many consumers are moving from single-use plastics to reusable alternatives, often assuming these have lower environmental impacts; however, reusable items frequently involve more resource-intensive materials and have notable use-phase impacts. This study used LCA to examine the GWP, water consumption, and primary nonrenewable energy use of reusable alternatives for single-use plastic kitchenware, calculating environmental payback periods. Findings indicate that reusable options can offset their initial environmental impacts, depending on usage frequency, consumer habits, and—specifically for GWP—the carbon intensity of the energy grid. A key takeaway is that consumer behaviour and usage patterns significantly influence the environmental impact of reusable kitchenware.
