SIR - Congratulations are due to those concerned with our landfill problem - now sorted. A simple, effective plan, according to a circular received today, ie: "...this will help to minimise the uncontrolled quantity of excess waste currently put out for collection and going to landfill".

Why didn't we think of it before? Of course. Just use the PURPLE plastic bags they have now delivered instead of the old BLACK ones! Hooray!

Oh well.
