  7. Abstract:
  8. Nowadays, cement has become the cornerstone of any modern society especially in developing countries. But, cement production process is highly energy intensive and emits significant volumes of carbon dioxide.According to the latest reports, Iranian cement industry accounts for about 14.5% of total industrial sector’s energy consumption and this indicates the importance of sustainable development for cement industry concerning national energy and environmental constraints.Based on these facts, current study assesses the technology improvement opportunities particularly waste heat recovery power generation (WHRPG) technology for Iranian cement industry. This needs identifying optimized mass and energy streams while performing trade-off balance between energy costs, irreversibilities and carbon externalities on the one hand and capitalizing for improved technologies on the other hand. To achieve this goal, the study applies an optimization bottom-up model with a cost minimizing objective through Iran’s 1404/2025 vision horizon regarding exergy destruction and carbon externality costs.The results reveal that integrating waste heat recovery power generation system and improving other production process technologies will induce a reduction in electricity demand of cement units as much as 43% in 1404 horizon
