Greening manufacturing practices in a continuous process industry Case study of a cement manufacturing company

摘要

Purpose - The paper aims to observe a continuous process industry, the cement manufacturing industry with the aim of identifying greening opportunities in its production operations. The study analyses areas pertaining to the cement industry that impact the environment with specific focus on the industry within a developing, lower income country. Design/methodology/approach - A cleaner production (CP) approach was used in a case study approach, focussing on issues such as gaseous emissions and particulate emissions. Both capital intensive and less intensive options are proposed. Source reduction and pollution prevention operations that were used in this study include chemical substitution, technology modification and on-site reuse/recovery/recycling opportunities. Findings - The paper provides insights about how change is brought about within a continuous process industry. It suggests that successful leaders act as "integrating forces" on two levels: integrating the elements of corporate identity structures and mediating between the corporate branding structures and the individual. Capital interventions included redesigning the clinker conveyor, as well as restructuring the dust transportation system. There is a need for the developing countries to track and identify modern interventions that are available within industry and adopt them. Research limitations/implications - The paper focusses on a single cement factory in a low income country, as the case study approach was used. As such, findings and options generated may not be generalized, as the processes from one industry to another tend to differ in different economies. Practical implications - The paper includes implications for the development of greening manufacturing practices in the cement industry. Originality/value - This paper fulfils an identified need to study how greening practices can be enabled and enhanced in a continuous manufacturing industry. The work informs greening practices at any level, with a focus of production experiences in the cement industry in a lower technology, developing economy that is less industrialized.
