Have you ever wondered how much waste your city produces during the holiday season? As well as pondering the question, London's Lord Mayor Vincent Keaveny went one step further by building a Christmas tree made entirely from trash collected in the city.

Far from being disgusting or messy, the whole thing is meticulously held together by a giant mesh structure, creating a colourful sculpture. But up close, there is no doubt – this particular tree is adorned with trash rather than the usual baubles and garlands.
