Abstract: The objective of this study is to identify the potential implementation of green manufacturing concepts on medium scale tea industries in Sri Lanka. Five medium scale tea factories located in southern province were selected as the sample and case study approach was followed. The data were collected through regular factory observations and secondary sources including published reports and documents of the companies. Material and energy flow diagram was used as the main tool for the analysis. The result reveals that there are significant environmental issues such as large-scale raw material wastage, and high level of energy, water consumption and harmful emissions. This study suggests that energy consumption can be reduced by introducing new equipment, methods and systems such as installing variable speed motors, power factor correction capacitors, variable frequency drivers, replacing light emitting diodes (LEDs) with compact fluorescents, implementing well-planned production schedules, and fixing net metering system and solar panels.
