Lifecycle Assessment of a Non-Phase-Transition Drying Pyrolysis and Mass Conversion Technology

A lifecycle model was established to explore the efficiency, economy, and greenhouse gas emissions of a non-phase-transition drying pyrolysis mass conversion technology, based on principle assessment. The evaluation scope included straw collection transportation, crushing, biomass pyrolysis, charcoal processing, waste heat utilization. results show that energy output/input ratio for 20.43, efficiency high. pure profit from treating wet USD 45.32 per ton, margin sales 52.11%, economic benefit equivalent emission CO2 34.10 g·MJ−1, demonstrating high environmental benefits. Therefore, technology is potential utilization with energy, economic, ecological
