Drivers and barriers to green supply chain management in the South African cement industry

Abstract

Background: The cement industry in South Africa is lagging behind the green supply chain management (GSCM) revolution that has influenced many sectors to re-evaluate their supply chain systems. Objective: This study was conducted to determine the significant drivers of and barriers to the implementation of GSCM in the South African cement industry, and thus to investigate the impediments to the implementation of GSCM in the cement industry. Method: A mixed-method approach was used to collect data from various role-players in the cement value chain. Geometric means were calculated from the scores of the survey conducted. Interviews were also conducted to confirm the results of the survey. An analytical hierarchy process technique ranked the individual drivers and barriers using the results from pairwise comparisons conducted. After ranking the drivers and barriers, a Pareto analysis was applied to determine the most significant drivers and barriers for the South African cement industry. Results: Overall, the seven most significant sub-drivers fall into three categories of main drivers: financial performance, competitors and organisational style. Ten barriers were identified as most significant and were categorised into five themes, namely, high capital costs, poor supplier commitment, high certification costs, weak marketing positioning and lack of awareness of GSCM. Conclusion: The identification of these drivers and barriers contributes to further research on improvements to GSCM process in the cement industry. The study shows that drivers of and barriers to the implementation of GSCM are not universally standard, and the ranking varies from one industry to another and from one country to another.
