A new study has shown that DW Reusables’ recently launched Fillbee reusable system for beverages generates around 46% less CO₂ compared to aluminum cans with plastic wrap, and 64% less CO₂ compared to single-use glass with cardboard.

A sustainable development master student at the Copernicus Institute for Sustainable Development at Utrecht University compared for his thesis the primary and secondary packaging: a Fillbee used in combination with reusable glass bottles, aluminum  cans wrapped in plastic film and cardboard packs with one-way glass bottles.
