If we return to using glass bottles, they will have to be delivered, collected and cleaned and deposits will have to be paid on them. The damage to the environment of all that waste of energy has to be taken into account and I am sure it will be. I know such a system will not necessarily be imposed without taking these considerations into account, but in other countries I have seen the huge difficulties that can arise over taking deposits. Such bottles have to be cleaned and transported, which uses energy, and a health issue also arises. We will have to tackle such problems through discussions with the industry.
