In Europe, inkjet technology has prevailed over other traditional tile decorating techniques, such as screen-printing and rotogravure, due to its higher productivity rates and lower manufacturing costs. However, the ink products used generate high volumes of hazardous wastes, which are increasing due to the growing demand for large decorative ceramic slabs.Ceramic inkjet inks are commonly made up of complex mixtures consisting of a heavy metal-based solid component along with inorganic pigments, refractory materials, ceramic frits, organic solvents and different additives. The presence of heavy metals, along with the organic nature of the solvents used, in the formulation pose a significant health risk and threat to the environment.Currently, all inject ink waste in the EU is sent to landfill following the chemical and a physical separation of the solid fraction. Although this waste management generates harmful wastewater in the cleaning stages, alternatives are not readily pursued due to the complexity of the separation process, the sub-micron particle sizes required, and the non-aqueous nature of the solvents present in the ceramic inkjet ink wastes. The use of ceramic inkjet inks generated 2,399 tonnes of hazardous waste in 2019, costing €14.4 million in disposal. Spain is responsible for 641 tonnes/year and Italy around 503 tonnes/year, representing a total annual cost more than €6 million. ... for more info please visit https://webgate.ec.europa.eu/life/publicWebsite/project/details/5702
