The report assesses the environmental impact of KeepCup’s reusable cups compared to single-use cups (paperboard, compostable) and other reusable options (bamboo, polypropylene). Using Life Cycle Assessment (LCA), the study evaluates factors like carbon emissions, water use, and energy consumption. It finds that KeepCups generally have a lower environmental impact over time, particularly when used frequently. Recommendations include promoting energy-efficient washing practices, using alternative materials, and improving recycling options. The goal is to support sustainable alternatives to disposable cups.
