The purpose of this study was to improve the overall equipment effectiveness (OEE) of the production process of the shredder operation of ABC company, an industrial waste management company which supplies pre-processed industrial waste as alternative fuel to a cement plant.


This case study investigated all possible availability and performance losses that caused the shredder system’s OEE and various problem-solving techniques, such as root cause analysis and Pareto analysis, were used to find the root cause of the reduced OEE.


After analysing this case study, three significant loss factors were identified from all the availability and performance losses, which caused the shredder system’s OEE losses. Practical solutions were found for the effect of those loss factors to improve the machine’s OEE and productivity.

Research limitations/implications

This case study has been concentrated on only analysing of losses and improvement of OEE in the production process and not about cost analysis between loss and improvements.


This paper shows how to improve the OEE of a production process through various problem-solving techniques by identifying its losses and how to achieve the best solutions for those losses in a practical manner.



The authors wish to express their heartfelt and profound gratitude to Dr Asela Kulatunga and Department of Manufacturing and Industrial Engineering, University of Peradeniya for the valuable guidance, assistance, and inspiration throughout the span of this research. Furthermore, they would also be thankful to ABC waste management company, department manager, colleagues, maintenance department employees, and all other third-party employees who helped to make these new initiatives succeed to improve the machine overall equipment effectiveness and keep continuous improvement to achieve the research targets.
