Meat industry is facing major challenges due to excess consumption of water, production of air pollutant emissions and waste generation which have an impact on environmental performance. International Organization for Standardization (ISO) standards’ implementation and lean are considered the main tools and techniques to achieve the highest level of process improvement benefits. ISO 14001 is potentially considered the most effective tool to improve the environment performance which focuses on degeneration, environment protection and sustainable utilization of natural resources. On the other hand, lean along with its tools and techniques has been adopted in meat industry to eliminate wastes in meat processing which also in turn leads to better environmental performance. Therefore, a conceptual framework is proposed which integrates ISO 14001 and lean elements in order to achieve synergetic environmental performance effectiveness and benefits that could be applied to meat industry.
