Having milk delivered to the workplace is a simple step any organisation can take towards a more sustainable food supply. Many local delivery companies still use and re-use glass bottles instead of plastic.
Using a local dairy will ensure your pints haven’t travelled far, support the local economy and are fresh and delicious. If you use a significant quantity, it’s worth finding a milk provider who can deliver in large containers, to further reduce packaging, and see if other organisations around you want to do the same.
