85% of fluid milk in the USA is packaged in monolayer HDPE packaging, with the result that any reduction in the amount of plastic used can have a major impact on reducing the carbon footprint.
This presentation discusses the results of studies of a progression of ways in which the amount of plastic used in the creation of gallon jugs can be reduced.
–Light-weighting through container design.
–Adding calcium carbonate as a filler.
–Light-Weighting + optimizing for calcium carbonate filler.
These results meet recommendations coming out of the Life Cycle Analysis study conducted by the Innovation Center for US Dairy which recommended light-weighting or container weight reduction as a key focus area for improvement in the supply chain impact of fluid milk.
A recipe for the gallon jug of the future is presented, and the hypothesis made that “Integrated Design” will be the next frontier in creating a more sustainable gallon jug for milk.
