The data for a life-cycle analysis of mineral water that is packaged in 333 ml PET bottles or aluminium cans are:
The bottles and aluminium cans are sourced in France and in both cases they are transported 1150 km to a company in Wales by train. While mineral water is packaged in 333 ml PET bottles or aluminium cans in the company. Then in both cases the products are transported 240 km to the Brookes Café by 32 tonne truck. On arrival, it is refrigerated for 72 hours on average before consumption. After use the university has a policy of recycling the bottles or cans.
