Kierronit

Kierronit is a fictional mineral often used in educational materials to illustrate principles related to circular economy and recycling. The name derives from the Finnish kierrätys, meaning recycling, underscoring its role as a teaching tool for closed-loop material lifecycles.

In the context of educational fiction, kierronit is described as a hydrated aluminosilicate with a layered structure that can undergo reversible phase changes, enabling disassembly into recyclable components. It is typically depicted as colorless to pale blue, with a vitreous luster and a Mohs hardness roughly in the 4 to 6 range. The specific gravity is commonly cited around 2.7 to 3.3 g/cm3. A representative hypothetical formula is given as a hydrated aluminosilicate with trace elements such as iron, magnesium, and calcium.

Occurrence and formation are framed as synthetic or lab-generated in teaching scenarios, rather than as a naturally occurring mineral documented in official catalogs. Kierronit is developed in simulations to demonstrate how material design influences recyclability, recovery efficiency, and end-of-life processing. The emphasis is on illustrating how reversible hydration or dehydroxylation can facilitate component separation and reuse.

Applications and significance in curricula center on using kierronit as a model for discussing sustainable material design, recycling pathways, and lifecycle assessment. While it has no standing in professional mineralogy, the fictional kierronit framework helps students visualize concepts related to resource recovery and a circular economy.
