Mayor Ken Livingstone has launched the country's first text service aimed at making recycling easier in London.
The move will allow residents to request details of collections by texting RECYCLE and their postcode to 63131.
Adverts will be displayed across the capital after 27% of Londoners admitted that they were unsure which day their waste is collected for recycling.
Eighty per cent of London residents now have access to a recycling collection, with the new initiative aimed at raising awareness. .
