What happens to free newspapers?

What becomes of the freesheets we abandon on the Underground?

In addition to Metro, City A.M. and assorted magazines aimed at Aussies, Kiwis and South Africans, the commuters of London can now avail themselves of 800,000 extra free papers each weekday in the form of new launches thelondonpaper and London Lite.
Which means a huge addition to the 20 tonnes of newsprint already being dumped every day on the seats and floors of the London Underground (sadly, there are no litter bins, dating back to the security risk posed in the days of the IRA).
