Green Operations Initiatives in the Formal Brick Manufacturing Industry: A Case Study of Vhembe District, South Africa

The growing global emphasis on sustainable industrial practices has catalyzed the transformation of traditional manufacturing sectors, including brick production. This study explores the integration of green operational practices within a formal brick manufacturing company in South Africa, highlighting its potential contribution to sustainable industrial development and principles of the circular economy. A qualitative case study approach was employed using field visits, semi-structured interviews with key personnel at FMB Bricks Ltd, and direct assessment of production activities to identify environmentally sustainable practices. The data collected were analysed thematically, revealing core sustainability initiatives such as enhanced material efficiency, internal reuse of kiln ash and broken bricks, dust and emissions control, and energy optimisation. These practices reduce environmental impact and align with circular economy strategies by promoting resource recovery and minimising waste. Despite these advances, notable challenges persist, including the plant’s vulnerability to power outages, resulting in continued reliance on energy-intensive clamp kilns, and the absence of an air quality monitoring system. To strengthen environmental performance, the study recommends gradually shifting toward renewable energy sources and adopting real-time environmental monitoring technologies. The findings suggest that with strategic investment and policy support, formal brick manufacturers can serve as catalysts for low-carbon, circular, and resilient industrial development.
