A Comparative Study of Carbon Emission of Wormwood Viscose Fiber and Flax Fiber for the Production of Antibacterial Nanofibers Based on GaBi Software

Because of its antibacterial properties, wormwood can be used in the production of nanobiomaterials. In this paper, each stage of the production process of wormwood viscose fiber and flax fiber was determined. The carbon emission of each stage of the production process of 1 ton wormwood viscose fiber and flax fiber was analyzed by GaBi software, and the environmental impact of the production process was evaluated by using the CML2001 method provided by the software. The results showed that a total of 1690.04 kg of carbon dioxide was emitted in the production of 1 ton of wormwood viscose fiber, 60% in the preparation stage, 36.36% in the acid bath stage and 3.64% in the treatment stage. A total of 1541.41 kg of carbon dioxide was emitted in the production of 1 ton of flax fiber, with the pretreatment stage accounting for 39.95% of the total amount, the alkali cooking stage accounting for 50.06% of the total amount, and the pickling stage accounting for 9.99% of the total amount. The results can provide support for the production of antibacterial nanofibers.
