The study was conducted to analyze the factors affecting the use of pig wastewater for crop cultivation in Hanoi city. Through the application of the Theory of Planned Behavior to develop the theoretical framework and structural equation modeling, the study showed that the behavior intention influenced the recycling behavior. Attitude toward the behavior (AT), social norms (SN), and perceived behavioral control (PBC) were important influencing factors on the intention to perform this behavior with standardized regression coefficients of ß = 0.96 (P <0.001), ß = -0.826 (P <0.001), and ß = -0.34 (P <0.001), respectively. These research results serve as the initial reference for policies and studies related to the use of pig wastewater.
