Meanwhile, the Sea Stone collection presents Sea Stone within a series of products with a more polished aesthetic. Recycled seashells are mixed with wood, soil and sand to create incense holders, trays and pencil cases.
Newtab-22’s largest use of the material is a decorative wall panel. Called Shelluminator, it is available in two texture variants, terrazzo or 3D stripe, and four different colours: ivory, black, blue and green. The tiles look no different from regular concrete tiles except for the natural iridescence of the seashells.
Currently based in South Korea, where the issue of seafood waste is rife, Newtab-22’s Sea Stone project highlights the value of discarded materials. However, its potential as a replacement to concrete is limited. At present, Newtab-22 carry out the process manually to avoid the use of heat, electricity and chemical treatments and ensure the process is as sustainable and affordable as possible.
An energy-intensive heating process would be required to replicate the strength of traditional concrete necessary for large-scale projects like buildings. This would be comparable to the method used to make cement, which accounts for half of all the CO2 emissions that result from using concrete.
Nevertheless, the studio is currently developing the material for commercial purposes and other ways to use Sea Stone sustainably as an alternative to concrete.
