One of the primary objectives of the London 2012 Organizing Committee was to achieve an environmentally-friendly Olympic edition. Thinking back to what the industrial and degraded area of Stradford used to look like prior to the British capital being awarded with the organization of the Games, that same area where the Olympic Park now stands, one is suddenly struck by the realization of just how much work must have gone into transforming the entire district into one of the greenest areas of the city. Suffice it to say that around 90% of construction waste from the demolition of the buildings present on the territory prior to the start of the works was used to build the new structures. In addition, many of the Games sporting facilities have been designed to be dismantled at the end of the competitions and reused for other purposes. Mondo has also played its part to contribute to a "green" Olympiad: the majority of the materials supplied by the company will remain property of the Organizing Committee, while around 30% will be returned to Mondo at the end of the Games for future use.
