Kaumera and the Calcite factory: two state of the art showcases for resource recovery in drinking and wastewater treatment
Two innovative showcases of circularity in water treatment will be visited: the Calcite Factory (drinking water) and the Raw Materials Plant (waste water). The Calcite Factory is an innovative factory where calcite (a byproduct of drinking water softening) is processed and made suitable for various product applications.
This pilot plant was built in the port of Amsterdam in cooperation with Advanced Minerals. Waternet reuses part of the processed calcite in the softening process. The calcite from this factory is used in the backing of carpet tiles, lime to produce glass and as a scrub for the cosmetics industry. In this way, the Dutch drinking water sector works towards the noble goals of a circular economy, leads to lower costs and the reuse of sustainable calcite.
Kaumera Nereda® Gum is a new biological raw material that is extracted from the sludge granules that form during the Nereda® purification process. This year, the first plant in the world to produce this innovative raw material will be built in Zutphen. Due to the unique properties of the biopolymer Kaumera, there are infinite possibilities for applications that previously could only be realised with chemical raw materials.
Kaumera can retain water but also repel it. These properties can be strengthened depending on the form in which Kaumera is used. It is also a large anionic molecule with many binding sites. This makes Kaumera extremely suitable as a binder and raw material for the production of co-polymers or composite materials.
