An environmental lifecycle assessment(LCA) in Germany has said that beverage cartons-across the fresh milk,juice and UHT milk market segments-offer environmental advantages to alternative forms of packaging for liquid dairy and juices.Reusable packaging options,such as glass bottles that are returned to food or beverage producers to be used again,are often assumed to be the best option for the environment.Based on an in-depth analysis of all three market segments-fresh milk,juices and UHT milk-the study said beverage carton performs at least as well,or in the case of fresh milk,even better than reusable glass bottles.It also found that both beverage cartons and reusable glass bottles outperform PET bottles for fresh milk,juice and UHT milk.Where no re-usable system is installed,beverage cartons are clearly advantageous.
