Application of Six Sigma in the Environmental Clearance Process of Mining Projects in India Introduction The mining industry in India is a critical sector contributing to economic growth. However, environmental clearance (EC) processes for mining projects in India are often lengthy and complex, leading to significant project delays and increased costs. Six Sigma, a data-driven approach for process improvement, offers potential solutions to streamline these procedures, enhance compliance, and minimize environmental impact. This study led by Dr. Vinay Sahay examines how Six Sigma methodologies can be applied to optimize the EC process, making it more efficient and effective. Six Sigma Overview Six Sigma is a systematic approach to process improvement that helps to minimize defects and variability. It employs two primary methodologies: DMAIC (Define, Measure, Analyze, Improve, Control) for improving existing processes and DMADV (Define, Measure, Analyze, Design, Verify) for creati...

Challenges of Poor Environmental Impact Assessments in Mining Projects: A Critical Analysis for India Introduction Mining plays a pivotal role in India's economy, contributing significantly to Gross Domestic Product (GDP) and employment. However, the environmental impacts associated with mining activities cannot be overlooked. To mitigate these impacts, regulatory frameworks require thorough Environmental Impact Assessments (EIAs) before granting environmental clearance for mining projects. Despite these regulations, the effectiveness of EIAs in India has been questioned, leading to delays and controversies in the clearance process. It is important to collaborate and prioritize the integrity of the EIA process for the long-term benefit of the environment, mining industry growth and communities affected by mining activities. This article critically examines the challenges posed by poor EIAs in Indian mining projects. Understanding Environmental Impact Assessments (EIAs) Env...
