Green Outdoors Local: inspiration during class

Location: Megchelen

Cleanup potential: 12 tons

In 2010, greenSand olivine was first applied in the outdoor garden at St. Martinus primary school in Megchelen, designed by Nico Wissing. The classroom is a green oasis, furnished with sustainable materials and focused on nature education. On days with good weather, this outdoor space offers an inspiring place for students who may also be allowed to do the "spa red test" to see that olivine dissolves carbonic acid (CO2) and turns into spa blue (not literally).
