SEDIMENTOS DE UM ECOSSISTEMA LITORÂNEO: experimentações com pó de exoesqueleto de caranguejo orientado ao design sustentável

Abstract

In the course of human evolution, along with the countless benefits of advances in science and technology, exacerbated consumption, the unbridled exploitation of natural resources and the intense disposal of solid waste have caused significant environmental detriment. Therefore, in order to promote a favorable future prognosis, it is essential to reflect on and target effective and sustainable alternatives in order to optimize quality of life, offering prospects for future generations and the ecosystem. Reflecting on the immensity of the sphere of design and its domain of interference, it is essential to link the design process to environmental issues. Whether it's through reflection, creation and/or improvement of existing materials through the exploration of innovative ideas and technologies, enabling new applications and possible solutions to current environmental challenges. In view of this, this study addresses the use of sustainability-oriented composites through the allocation of crab exoskeleton waste discarded by bars located on Avenida Litorânea in São Luís - MA, in red ceramic mass. In this context, the aim is to analyze the effect of incorporating these materials and their characteristics in terms of physical and mechanical properties, as a proposal for application in new production cycles. The investigation was carried out using percentages of 5%, 10% and 15% waste. These were subjected to three firing temperatures: 950 °C, 1000 °C and 1050 °C. Based on the results, it is anticipated that the research showed a significant increase in the strength of ceramics made with 5% and 10% crab waste. These were subjected to a firing temperature of 1000 °C. Therefore, the results prove the importance of research that stimulates reflection on environmental impacts and new ways of elucidating or minimizing the effects generated by the form of disposal and consumption. It also encourages new studies on the subject, favoring the areas of product design, materials and engineering.
