Raw material Kaumera

Energie- en grondstoffenfabriek / Grondstof Kaumera

Kaumera (‘chameleon’ in Maori) is extracted from sludge granules from the Nereda purification process. This saves 20% – 35% of sludge from being transported and destroyed, which saves a lot of energy and CO2-emissions. It is a binder and adhesive material, it is fire resistant and can absorb water but is also water repellent. Kaumera can be applied as coating for seeds and fertilizers and it ensures hardening of concrete and thereby prevents cracking. Omlab uses Kaumera as a binder in the 3D-printing paste.
