How The Green Dream of Eddy Wijnker started with a Stone ... greenSand

Falling Stones

Founder and Director of greenSand Eddy Wijnker: "In 2008 I lived and worked in China and saw after the middle of the country was effected by a shallow, heavy earthquake - green coloured stones were falling down the hill, and this stone nearly hit my head.... Curious as I am, I picked up the stone. It turned out to be Olivine, an igneous rock. Olivine is formed in magma which is rich in magnesium, and arrives during volcanic eruptions as lava."


The Mineral Olivine

"Back in the Netherlands, I joined Olaf Schuiling, emeritus professor of geochemistry - Utrecht University. According to Schuiling the 'China' stone is called Olivine and the key to Climate Change. One of the excellent features of the stone is sequestering CO2 with Olivine by enhanced weathering! I also met Nico Wissing, garden designer and Founder of the 'NL Green Label' who is in search of sustainable garden products. Schuiling and Wissing were sharing their experience and knowledge of the magic stone 'Olivine'. That is how my green dream was awakened."



"Inspired by the natural simplicity in which olivine is cleaning up CO2 and based on the research of Professor Dr. ir. Olaf Schuiling, I have been wanting to make olivine accessible to everyone. In order to clean up CO2 and combat Climate Change through enhanced weathering like the Earth has been doing for millions of years.

Thinking back to my primary school 'The Hour-glass' the company name and logo were born! It became my green mission spreading Olivine for the future of our planet. The simple, natural and age-old method of binding CO2 with olivine is the key to Climate Change."


Mine it, mill it, spread it

There are still 25 million dollars ready for the winner of the Virgin Earth Challenge. The contest was announced in 2007 by British entrepreneur Sir Richard Branson. The aim is to develop a commercially viable, scalable technology to get a billion tons of greenhouse gases out of the air annually, for at least ten years.

Of the 2,600 submissions, 11 were selected, including Schuiling’s plan. In Schuilings contribution to this ‘challenge’, the main role is reserved for the mineral Olivine. He wants to scatter Olivine over fields. Mine it, mill it, spread it. More information about Schuiling’s plan and applied, technical and scientific research: The Olivine Foundation SmartStones
