Tarkett – Walk on (residual matter from) water

GOAL & TARGET
Tarkett is the first company that uses (calcium carbonate) lime for the production of carpet tiles. The lime is a residual product from drinking water production, from Dutch drinking water companies.
Tarkett – Walk on (residual matter from) water
solution

Carpet manufacturer Tarkett has succeeded in developing lime-based carpet tiles: a residual product from the production of drinking water. Tarkett works together with Reststoffenunie, a group of Dutch drinking water companies for this.

Upcycling of lime from drinking water

It is the first time that calcium carbonate (lime) is used worldwide for the production of carpet tiles. Tarkett cooperates with Reststoffenunie, an association of drinking Tarkett Carpet Tiles It is the first time that calcium carbonate (lime) is used worldwide for the production of carpet tiles. water companies, for up-cycling lime. The lime itself comes from the drinking water companies Brabant Water and WML (Water Maatschappij Limburg). When processing drinking water, a lot of calcium carbonate remains after the groundwater has been softened. Softening is a necessary step in making groundwater suitable for drinking water. Softening is also important for another circular reason: softened water prolongs the life of household appliances because it reduces calk. The remaining lime now also has a high-quality use. This lime form has now been positively defined in accordance with the Cradle-to-Cradle criteria and is now used for the production of EcoBase carpet tiles. Thanks to the processing of this lime, this product is 100% recyclable in Tarkett’s own production process.

Ambitions Tarkett, Brabant Water and WML

Tarkett is committed to the development of products suitable for intake and recycling in a non-toxic closed loop, the foundation for a regenerative circular economy. The use of the lime is a next step in realizing this ambition. As the first climate-neutral drinking water company in Europe, Brabant Water’s ambition fits in seamlessly with this. WML is already recycling 99% of its residues and sees its collaborations around circular innovations increase.

A local breakthrough

With the help of Sibelco, a supplier of industrial minerals, the size and distribution of the calcium carbonate particles for Tarkett has been tailored to suit. This has enabled Tarkett to organize the acquisition and processing of the lime on a local scale. This can therefore rightly be called an innovation in the value chain. In its continuous ambition, Tarkett reached an important milestone in 2017: 3,400 tons, an equivalent of 170 full truckloads, of upcycled chalk was used in Tarkett carpet tiles.

The Best Practices

Holland Circular Hotspot (HCH) wants to support international cooperation on the circular economy, with the aim of creating business opportunities and promoting the exchange of knowledge and innovation.
