This LCA report evaluates the environmental impact of Corplex’s reusable plastic flower transport box compared to a single-use carton box, aiming to identify the “breakeven” reuse point where the plastic box’s impact becomes lower. Based on theoretical data, four scenarios were modelled, assessing the effects of transport and tertiary packaging. The results suggest that reuse impact is heavily influenced by system variables, including pool size, replenishment rate, and box losses. The study includes a tool to calculate breakeven points, underscoring the need for optimising these factors for effective environmental benefits.
