Instead of being discarded as waste, soapstone is being given a new life as a valuable component in the Sand Battery. This reduces the need for extracting and processing new materials.

“The principles of the circular economy challenge the mining industry to seek new solutions. For instance, we’ve started using recycled ceramics in some of our new fireplaces. This innovative Sand Battery cooperation is one example of the fresh thinking we need more of,” said Heikki Vauhkonen, CEO of Tulikivi.
