How can we turn the marble industry into a circular economy?

Marmorello, the marble pastry roller, is a handy kitchen utensil that helps you to archive the perfect dough height for your pastry goods. Due to its exchangeable silicone rings, three different dough heights can be preset. The heights chosen are the standard heights used in professional bakeries, which are 2mm, 3mm, and 4mm. The product consists of a core sample of a marble quarry, which has the form of a very long stone roll with a diameter of 5,7cm. The core sample naturally breaks into smaller parts. For the pastry roller, all parts of the core sample that broke in a length between 35cm and 45cm or, in the longer version, between 56cm to 60cm are selected. The only work that has to be done to them is two little indentations with a distance of 30cm to norm the length of the pastry roller. Then, the exchangeable silicone rings for the dough height are added, which fit perfectly into the indentations. The intentions for the production of the pastry roller are the usage of leftover material and the application of very few processing steps, while still archiving a normed product. Since the core samples are not used after their geological analysis, they currently are disposed regardless of their perfect cylindric form. By turning them into a useful object the precious marble can be preserved and is thus not going to waste, while the pre-given form by the drill saves energy and labor forces in production.
