The Olympic Development Authority (ODA) is ahead of its target to re-use 90 per cent of material from demolitions.
Head of sustainable development and regeneration, Dan Epstein said it was an unprecedented achievement for such a large project.
"Much of these materials will then be integrated into the designs of the new venues and parklands, ensuring there is continuity between the history of the site and its future as the largest new urban park in Europe," he added.
The ODA said it has reclaimed 80 lampposts, 160 manhole covers, two tonnes of red bricks and 41 tonnes of paving.
In addition to re-using the man-made materials on site, the project intends to recycle complete buildings to be re-assembled off site and translocate wildlife and create new habitats to the north of the park.
The preparations for the Olympics in 2012 are costly, however the area should benefit from additional commercial lettings and new offices.
