In this study the mechanical, thermal, surface properties and fracture behvaiour of ALQEMITE® material containing 10% and 15% recycled industrial spill are evaluated and compared to the control group made of virgin ALQEMITE®. Additionally, this study explores potential sustainable applications for these materials without determining an optimal mixture. The study includes a Life Cycle Analysis to evaluate the environmental advantages of using recycled ALQEMITE® in the development of possible applications, thus promoting sustainable manufacturing practices.
The methodology adopted involves a comprehensive analysis of the properties of the material and an evaluation of potential applications. Initially, mechanical properties are examined to assess the tensile and flexural strength, fracture toughness and hardness of the material.
The thermal properties are evaluated to ascertain the materials' short-term heat resistance, stiffness and thermal stability. Furthermore, surface finish and fractography are used to analyse surface roughness and fracture behaviour respectively, to individualize surface parameters and to understand the causes of failure.
Subsequently, potential applications are evaluated, leading to CAD modeling and finite element analysis simulations of the chosen application.
Ultimately, a comparative life cycle analysis is performed to assess the environmental impact of the chosen application created with the recycled mixtures versus the control material.
The study reveals that while the reference material generally exhibits superior performance, the results of 10% and 15% mixtures closely follow it, indicating that the two recycled groups did not decrease significantly compared to the control group. The 10% and 15% groups excel in specific tests, Vickers hardness and Charpy unnotched tests, respectively.
The 15% group showed a slight improvement in thermal characteristics, but the result was negligible compared to the reference, indicating that there was no loss of stiffness in short-term thermal scenarios. The surface analysis demonstrated that the control material has the smoothest surface and that the surfaces of 10% and 15% mixtures did not worsen excessively, remaining within the fine surface finish range.
In terms of fractographic analysis, the results indicate that the recycled content modifies material integrity and fractural behaviour. From these results, a structurally sound shelf was designed and its life cycle analysis demonstrates the environmental benefits of recycling. These findings support the potential for the reuse of discarded materials in new applications, which reduce the environmental impact.
