Inovações tecnológicas para o aproveitamento sustentável dos resíduos de mármore: uma revisão

Abstract

The massive generation of waste from marble extraction and processing represents an environmental and economic challenge. This literature review, based on relevant sources, examined research, methods and technologies for the sustainable use of this waste. The studies demonstrate the technical, environmental and economic feasibility of using marble waste as aggregates in concrete, mortar, road bases and as organo-mineral corrections in the remediation of contaminated soils. The methodology was based on scientific production published in the Scopus database, with publications covering the last ten years. 37 articles were selected, resulting in the identification and classification according to their research area, distributed into three groups: sustainable use in the construction industry (31 citations), reuse of mining areas and rehabilitation of degraded soils (08 citations), resource management and circular economy (08 citations). The application of characterization methods such as granulometry, mechanical resistance tests, durability, microstructural and chemical analyzes are crucial for the use of marble waste. Innovations include the view of waste piles as elements with potential for requalification and tourism, and the synergistic use of waste with other materials for soil remediation. In this way, the reuse of marble waste contributes to the circular economy, reducing the environmental impact, enabling the optimization of these resources, with fewer landfills and new extractions. Continuous research is vital to overcome challenges such as material variability and expand applications.
