Sustainable stones and sand

All gradations offered by greenSand are 100% natural and come from olivine-rich rocks such as serpentine and/or dunite. Before greenSand is offered on the market, it is first extensively researched. On this page you can read more about the research into Olivine.

according to ISO 9.001

Initial quality control Olivine

Before we offer our products to the market, the rock is extensively tested for the purity and quality of the mineral Olivine. These so-called batch inspections are carried out by the international certification and inspection agency SGS.

A common problem with rocks is the excess of asbestos. Asbestos is a natural mineral that is veined through the earth's crust. Thanks to SGS, we can guarantee every batch that our rocks are safe and below the permitted asbestos standard.

Both the mines and SGS have the ISO 9001 standard.

in accordance with ISO 14.001 & EMAS

Standards for sustainable mining

greenSand only works with mines that annually renew their sustainability management systems and have them inspected. Two of these systems are ISO 14.001 and Eco-Management and Audit Scheme (EMAS). These two systems are internationally recognized and are a requirement for cooperation.

In accordance with NEN 5896

Polarization microscope research

We want to be sure of our business and of the products we market. That is why, in addition to SGS, we have engaged an external party to examine the rock. Thanks to the external party Eurofins, we can now say with 100% certainty that there is no form of asbestos in our rocks.

The following asbestos types have been excluded by means of a polarization microscope: Chrysotile, Amosite, Crocidolite, Tremolite, Actinolite, Anthophyllite.

Life Cycle Assessment (LCA)

Soon available for all our greenSand Olivine grades.

Environmental Cost Indicator (MKI)

Soon available for all our greenSand Olivine grades.

Voor het Ministerie van Infrastructuur en Waterstaat is er in 2020 door de Inspectie Leefomgeving en Transport een onderzoek uitgevoerd met als doel te beoordelen of wij voldoen aan de Europese REACH-verordening
Er zijn monsters genomen en deze zijn op asbest onderzocht door SGS.
