Indeed, two thirds of the steel used in the stadium’s entire roof is recycled, cutting construction costs by a cool half a million quid.
Something like two thirds of all steel is recycled you fool!
The metals industry has a recycling rate higher than just about any other: vast networks of scrap dealers all over the world collecting the stuff, chains of refineries that suck it in and process it. Because it\’s valuable and people can make a profit from it, naturally.
Hell, Nucor, one of the largest steel producers in the world, uses nothing but scrap as an input.
No waste will go to landfill, for the first time in any Games.
That\’s bollocks. There was some thorium contamination found on site. While it is possible to extract it no opne would be stupid enough to do so: hoick it into landfill and I\’m certain that\’s what they did do.
As The Sunday Telegraph has revealed, 350 tons of ore must be mined to produce each gold medal.
That sounds bloody strange.
If they were from virgin material that would still sound strange.
The London 2012 Olympic medals weigh 375-400g, are 85mm in diameter and 7mm thick.
– The gold medal is made up of 92.5% silver and 1.34% gold, with the remainder copper (a minimum of 6g of gold).
Gold ore these days is about 1 gramme Au per tonne ore. Ag and Cu are of course far, far higher than this. So quite where the idea of 350 tonnes of ore comes from I\’m not sure. 350 tonnes of rock moved, that might make sense, but not 350 tonnes of ore (for only a small portion of the rock you move to get at the ore is actually ore).
The precious ore for the medals has been supplied by London 2012 sponsor Rio Tinto and was mined at Kennecott Utah Copper Mine near Salt Lake City in America, as well as from the Oyu Tolgoi project in Mongolia. For the small amount of non-precious elements that make up the bronze medals, the zinc was sourced from a mine in Australia as well as from recycled stock, while the tin originates from a mine in Cornwall.
Although that does explain the 350 tonnes bit. They\’re mining copper at Kennecott and gold is only extracted as a byproduct. You wouldn\’t open that mine just for the gold in it. But if you calculate the ore moved to get the gold you\’ll vastly overstate what has to be moved, because you\’re ignoring the fact that you\’re getting vast amounts of copper at the same time as that small amount of gold.
I do understand why they do this: Kennecott gives the ore for free as a sponsor. But given that we\’re still recycling gold and silver from the Paharoahs, from the Temple in Jerusalem, as well as granny\’s gold tooth from her funeral last week, recycling copper from motors, power lines, telephone cables and ships\’ propellers, there is no necessity to produce from new at all. In fact, the recycling of all of these metals outweighs the new production.
The campaign draws on a drive by its other founder – Dale Vince, head of the green energy firm Ecotricity – to turn his Conference League football team, Forest Green Rovers, into the world’s most environmentally friendly.
The club has banned red meat for players and fans, installed solar panels, and established the world’s first organic football pitch, free of artificial fertilisers and herbicides and mowed by a sun-powered robot.
Doesn\’t that just sum up the tosspottery of these people?
