The temporary structure, which is one of four McDonald’s restaurants in the park, is designed to be reused and recycled after the London Games.

The company spent three years planning the design and structure of the restaurant to ensure it would create a contemporary and welcoming atmosphere, with minimum impact on the environment.

"London 2012 is set to be the most sustainable Games and this ambition inspired us not only to fulfil our role as official restaurant in the catering operation behind the event, but also to bind sustainability into the heart of our state-of-the-art Olympic Park restaurants," said McDonald’s UK CEO Jill McDonald.

After the Games, 75% of the restaurant will be reused and most of the remainder will be recycled.

"With around 15 new restaurants planned to open during the next 12 months and McDonald’s major restaurant redesign programme on schedule for completion by the end of the year, every reusable fixture and piece of equipment will be used again," a spokesperson said.
