Olivine more sustainable than CO2 storage in soil

UTRECHT, 12 Dec 2009
Adding finely ground olivine to garden soil, potting soil and as a semi-hardening for road and roof covering is more sustainable and cheaper in the long term than storing CO2 in the ground. This says Eddy Wijnker of Olivine Group. On Saturday afternoon, Eddy handed out a thousand sachets of greenSand to the Dutch delegation for the climate conference in Copenhagen. The delegation, including Minister Jacqueline Cramer of VROM, left Utrecht for the Danish capital on a special Copenhagen Express. 'The absorption of a ton of CO2 by finely ground Olivine currently costs us 65 euros,' Wijnker calculates. 'As more Olivine is used for road construction, roofing and the garden, the price goes down by leaps and bounds.' An opinion shared by Professor Olaf Schuiling of the University of Utrecht, who was the first to demonstrate the CO2-reducing effect of olivine and has been advocating the large-scale use of olivine for years.
By distributing sprinkle bags of olivine, greenSand wants to bring the mineral to the attention of politicians, citizens and entrepreneurs. With 640,800 tons of Olivine, CO2 can be cleaned up by 0.8 megatons. This amounts to spreading 0.2 mm greenSand over an area of ​​1,068 km2 (one third of the province of South Holland).
