The pile, over 10ft tall and just as wide in clear plastic bags,demonstrates how much street litter is collected each day at a cost of £4m ayear.
The council says that cost is the equivalent of running a library service for a year; repairing 100,000 potholes; providing 210 residential care places for the elderly; or building half a primary school.
One side of Clapham High Street was cleaned as normal this morning while the other was left dirty.
It was all to show the amount of litter that is dropped in 24 hours.
Lambeth was just one of the local authorities that took part in a social experiment this weekend, in partnership with Keep Britain Tidy, to reveal the extent of the nation's littering behaviour.
The group say £1billion is spent cleaning the UK's streets every year which could pay for 4,400 libraries, 27,000 paramedics or 32,000 fire fighters.
The charity Keep Britain Tidy today released the results from its biggest litter count yet.
Volunteers helped to count the amount of litter on our streets.
In London, 55 people signed up, and they counted more than 2,230 pieces of litter.
