Abstract
Faced with the growing consumption of energy worldwide, humanity is in search of a sustainable energy matrix. Such a change is extremely important and necessary so that the current challenges related to climate change, scarcity of natural resources, pollution, energy security, sustainable development and access to energy are faced. The transition to renewable energy sources is crucial to reducing greenhouse gas emissions, ensuring energy availability in the future, promoting a cleaner and healthier environment, stimulating economic growth, as well as enabling access to energy in regions and communities that still do not have adequate access. It is a fundamental shift towards a more sustainable and resilient future. The hydrogen-based economy should be part of a possible solution to the energy problem. Hydrogen is the known fuel with the highest calorific value on a mass basis, and the simplest and most abundant gaseous element on the planet. The generation of hydrogen can be obtained by metallic ways, for example, by the oxidation of aluminum in an alkaline solution. The use of recyclable metals, such as aluminum in this study, is an option for sustainable hydrogen generation processes. However, like any chemical reaction, part of the products generated are waste, some of which are harmful to the environment, thus making the production of sustainable fuels unfeasible if an appropriate industrial technological destination is not found for them. In this context, the Optical Emission Spectroscopy with Inductive Coupling Plasma (ICP-OES) technique was chosen as an essential characterization tool for studying the waste, particularly aiming for conscious disposal. Through this technique, it is possible to obtain information about the chemical composition of the samples, identifying the elements present and allowing complete control of the reaction. This provides a completely sustainable chain of processes for hydrogen production as a renewable energy source, making it a promising perspective for technological advancement and the transition of the energy matrix towards a more sustainable future. Consequently, besides gaining better control and safety in the reaction, these insights into the generated waste are valuable. Not only do they help comprehend the environmental implications, but they also aid in making decisions about waste management and recycling processes, with a primary focus on appropriate disposal and optimizing their applications.
