Instead of piling it up in a big landfill, we re-use it in stone paper. Thus, we make an infinitely recyclable product, out of waste. The calcium carbonate is ground to a fine powder and combined with the heated resin. Pneumatic systems work this process. The heated resin 'glues' the stone elements together.

Many studies use high levels of calcite, such that most of the calcite acts as a filler. Studies using lower additions, 1–10 wt.%, confirm that mineralogical changes result but are not readily comparable with the approach developed here. An analysis and interpretation of the literature will be presented in a subsequent paper [13].
