The Olympic Delivery Authority has announced that nearly 2M.t of contaminated soil has been cleaned for reuse on the Olympic Park in the UK’s largest ever soil-washing operation.
The green clean-up of the 2.5km2 Olympic Park, much of it contaminated through decades of industrial use, has consistently beaten its tough sustainability targets since it began nearly four years ago. The ODA also published this week a map showing the ‘Green Build’ of the Olympic Park venues and parklands is on track and details of the London 2012 sustainable transport plans.
Five soil-washing machines have successfully completed cleaning most of the IM.m3 of soil contaminated with oil, petrol, tar, cyanide, arsenic and lead. Over 80% of contaminated soil has been cleaned for reuse on the Olympic Park using soil-washing, bioremediation beds (large-scale composting) and sorting machines, and over 98% of demolition materials on site have been recycled.
ODA chief executive David Higgins said: “Delivering one of the UK’s most complex and greenest clean-up operations on time and on budget is a major milestone. With the soil washing complete the focus now moves on to the ‘Green Build’ and ensuring sustainability remains at the heart of our work to deliver the venues and parklands for the Games and legacy.”
