The Stone Sludge Circular Coating is a natural paint made from waste sludge from the stone industry and minerals. It can be mixed with natural pigments or granules to create various surface effects, allowing users to transform spaces and craft creative items.

To make the coating more accessible, R2R was developed—a portable, organized, and user-friendly toolbox for easy display. The outer box features three stone textures in monochrome foil-stamped black, reducing printing to align with environmental principles.

Inside, the toolbox has four layers for organizing coatings and tools. The first layer holds instructions, coatings, and pigments, while the second contains mixing and application tools. The third and fourth layers store testing samples. The entire structure is made from recycled paper materials, reinforcing the eco-friendly ethos. Measuring spoons and powder bags are paper-based, sealed with paper-coated wire ties to minimize plastic use. The test samples are secured with a snap-fit design for easy handling and display.

This toolbox embodies innovation in circular design and sustainability, enhancing the reuse of stone waste and providing a platform for users to blend creativity with practical application.
