Sustainability key facts

  • 98% of material from Olympic Park demolition work was reclaimed for reuse and recycling – exceeding a target of 90%
  • 64% of construction materials were transported to the Olympic Park by rail or water, thereby reducing the project’s carbon footprint
  • 88 ‘light pipes’ in the Copper Box let natural light into the venue, achieving annual energy savings of up to 40%
  • 100% sustainably sourced timber used to build the Velodrome
  • 650 bird and bat boxes installed across the Olympic Park
  • 4,000 colour-coded recycling bins and composting bins are being placed throughout venues and the Olympic Park, aiming to achieve 70% re-use, recycling or composting during the Games
  • 10,000 tonnes of steel used to create the unique design of the lightest ever Olympic Stadium
  • 2 million tonnes of soil were cleansed of pollutants and more than 80% of soil was reused on site in the UK’s largest ever clean-up of contaminated land
  • 14 million sustainably sourced meals will be provided by LOCOG during the Games

 

Parklands – did you know?

  • The first of 4,000 new semi-mature trees are taking root in the Olympic Park and Olympic Village, in what is thought will be the largest one-off planting of its kind in the capital

Soil cleaning – did you know?

  • Five soil-washing machines have successfully completed cleaning most of the one million cubic metres of soil contaminated with oil, petrol, tar, cyanide, arsenic and lead
  • More than 220 buildings demolished with 98 per cent of the materials by weight recycled, well over the 90 per cent target
  • Over 5km of riverbanks replaced or refurbished and 30,000 tonnes of silt, gravel and other materials dredged from the rivers

Aquatics Centre – did you know?

  • Includes two 50m swimming pools and a 25m diving tank – contain over 10 million litres of water and will be and lined with 180,000 tiles

  • Curved steel structure made up of more than 2,500 sections of steelwork. Shape is designed to reflect the geometry of the cycling track, rising in height by 12m from shallowest point to the highest
  • At 30kg/m2, roof weighs roughly half that of any other covered Velodrome
