New research from Pattimura University in Ambon, Indonesia, highlights the potential of inorganic chemistry to address both environmental challenges and resource management. Professor of Chemistry Hellna Tehubijuluw has emphasized the strategic importance of transforming industrial waste and locally sourced materials into valuable, functional materials to support sustainable development.
A Shift in Inorganic Chemistry
Over the last two decades, inorganic chemistry has evolved beyond the study of compound structures. It is now being applied as a practical solution to issues related to the environment, energy, and materials science. This shift is particularly significant for Indonesia, a nation with abundant natural resources but also facing substantial industrial waste and underutilized local materials.
One example of this transformation is the re-evaluation of red mud, a byproduct of bauxite extraction traditionally considered an environmental problem. Researchers now view it as a potential source of metal oxides that can be converted into functional materials.
From Waste to Functional Materials
Through techniques like hydrothermal processes, sol-gel techniques, impregnation, and coprecipitation, red mud has been successfully converted into synthetic zeolite ZSM-5 and metal oxide-based composite materials. These materials possess unique properties, including controlled porous structures, high surface areas, and effective adsorption and photocatalytic activity.
These newly created materials are capable of both absorbing pollutants and actively breaking them down when exposed to light, making them potentially useful for treating domestic and industrial wastewater. Researchers have also modified iron-rich soils, including Humuturi soil in Maluku, into Fe-ZnO–based photocatalytic materials.
The research is described as practical and replicable even in laboratories with limited resources. Beyond academic benefits, this work could lead to the development of non-metallic minerals, the production of silica gel and zeolites, and the creation of new wastewater treatment solutions.
Future Potential
Professor Tehubijuluw believes that with collaboration between universities, local governments, and communities, Maluku could become a center for inorganic materials research, leveraging its local resources in eastern Indonesia. Further research could focus on refining these processes and scaling up production. It is also possible that similar approaches could be applied to other types of industrial waste and locally available materials across Indonesia.
