Sir - Waste takes up a good deal of space in your paper, week after week. Excessive packaging is rightly blamed for the huge amount sent to landfill. One of the worst examples of all the unnecessary packaging must be the bubble packs for pills.

They are not even practical - as often as not, the wretched pill shoots out and disappears from sight. Manufacturing them must increase the price, and involve a "carbon footprint". And they are placed in a cardboard box - which is handed to the customer in a plastic bag . . .

Can we persuade the pharmaceutical companies to go back to using little bottles - which are much more convenient, and can even be reused many times?
