A cradle-to-gate life cycle assessment (LCA) is conducted on beer production by introducing the raw material planting and malting into the research system boundaries based on the brewing stage with the application of Gabi 5. 0 software. Global Warming Potential (GWP),Acidification Potential (AP),Eutrophication Potential (EP),Abiotic Depletion Potential (ADP),Human Toxicity Potential (HTP) and Photochemical Ozone Creation Potential (POCP) are analyzed as the environmental impact factors in the life cycle of beer production. The results indicate that the GWP is the main environmental impact in the beer production,which accounts for 43. 75% of the total environmental impact potential. Regarding the extent of environmental impacts,these factors tank as GWP,EP,AP,HTP,POCP and ADP. Across all the stages considered,the bottle filling stage shows the dominant influence on the environment with the contribution of 39.77% of the total environmental impact potential,and is followed by the raw material planting stage. The highest GWP,ADP,HTP and POCP values are recorded in the bottle filling stage,whereas the raw material planting stage has the highest EP and AP values. Cleaner production (CP) schemes are implemented to reduce the energy consumption and environmental impacts,including improving the transportation pipe of the bottle filling stage,heat recovery by using air compressors and steam reutilization. After the implementation of the CP schemes,the steam and electricity consumption is reduced by 247. 66 MJ and 4. 46 kWh,respectively,and the GWP in the bottle filling stage decreases by 19.18%,showing considerable environmental and economic benefits.
