Impact of Mining on Environment and Waste Management: Challenges and Solutions

This comprehensive overview explores the profound environmental effects of mining, including acid drainage and habitat destruction, and highlights the crucial role of reducing consumption of minerals and metals such as aluminum, iron, copper, and more. It discusses the complexities of solid and hazardous waste management in the United States, the fate of waste materials in landfills, and the importance of recycling and sustainable practices. Furthermore, it addresses federal legislation, pollution issues, and innovative remediation strategies like bioremediation, emphasizing the need for environmental justice in waste management.
