Quartz sand, an increasingly scarce material, has not yet been replaced. Unlike concrete and other high-consumption materials, glass can be infinitely recycled. It can even be regrinded back into sand, which means the material is in a closed cycle if the additives are harmless. Unfortunately, many glasses are not. “From the ashes” is 100% natural glass, with no toxic or limited additives and made for generations to come.

The solution: using waste from renewable raw materials. Private wood-burning stoves are also a valuable source, and many more have been tested, such as grills and fire pits. These renewable raw materials are available in large quantities in many cities and have so far been discarded. Potassium carbonate can be extracted from wood ash. A forgotten flux that was used in earlier years. Sea shells are largely composed of calcium carbonate and were formerly part of limestone. Finely ground, they give glass its well-known durability.

This new glass uncovers infinite supply chains by using waste that previously had no value: wood ashes from pizzerias and shells from seafood restaurants.
