A Zero Waste Strategy in mining is a comprehensive, long-term organizational plan that defines the targets, initiatives, technologies, partnerships, and governance frameworks required to progressively eliminate waste generation across all stages of mining and processing in bauxite, gold, iron ore, and diamond operations. It provides the roadmap for transitioning from conventional waste-generating operations toward a circular, resource-efficient model in which all material flows — solid, liquid, and gaseous — are systematically managed to minimize environmental impact and maximize resource recovery. A robust Zero Waste Strategy typically begins with a detailed waste inventory and characterization exercise to understand the types, volumes, and composition of all waste streams generated, followed by the identification and prioritization of waste reduction opportunities using a waste hierarchy framework: eliminate, reduce, reuse, recycle, recover, and dispose as a last resort. In bauxite mining, a Zero Waste Strategy addresses bauxite residue management and aims to find beneficial uses for red mud. In gold mining, it targets tailings reprocessing, reagent recovery, and the elimination of hazardous waste from cyanide handling. In iron ore, it addresses silica-rich reject material and process water recycle. In diamond mining, it targets kimberlite utilization and chemical reagent minimization. The strategy establishes measurable targets, assigns clear ownership, allocates investment budgets, and defines reporting mechanisms to track progress — ensuring that zero waste becomes embedded as a core operational commitment rather than an aspirational slogan.
