Since LCA measures both direct and indirect environmental impacts, it is thought to be the most comprehensive approach to creating a more sustainable controlled-environment agriculture system. In this study, the current version of openLCA (Version 2.1.1) and EcoInvent database was used to analyze the environmental impact of the structure, the aquaponic and hydroponic systems and the crop production materials, along with the other objectives of the research which are evaluation of plant growth and make a comparative economic analysis. From the results acquired, it was found out that hydroponics exhibits lower environmental impacts compared to aquaponics across all assessed categories, particularly in freshwater eutrophication (5.3354 x 10−3 and 1.0823 x 10−1) , global warming, (1.9566 x 101 and 8.8671 x 101), and terrestrial acidification, (8.3737 x 10−2 and 3.0855 x 10−1). The tilapia cultivation in aquaponics is the major environmental hotspot while for the hydroponics are polypropylene granulate production, as well as the utilization of fertilizers. For the plant growth, the aquaponics system initially promoted leaf breadth of 1.7457 cm and plant height of 2.5292 cm. However, by the end of the six-week period, the hydroponics system led to larger leaf breadth of 8.9333 cm and plant height of 12.5083 cm compared to the aquaponics system with 8.3542 cm and 11.7920 cm for leaf breadth and plant height, respectively. For the yield, the hydroponics system yielded more lettuce (1.168 kg) compared to the aquaponics system (1.074 kg), with generally higher yield per pipe, except in two instances. And for the economic analysis, both systems showed a positive ROI which are 51.027% and 28.508% for hydroponics and aquaponics system, respectively.

A common method for assessing the emissions and resource consumption of aquaculture and agriculture is life cycle assessment (LCA).
