Abstract: Abstract Toilet-linked anaerobic digesters (TLADs), commonly called biogas toilets, are integral to ecological sanitation technologies implemented in Burkina Faso for over a decade to improve the population’s living conditions. However, the adoption of TLADs is low, and there is an incomplete understanding of the barriers hindering their dissemination within the community. Therefore, this study aims to provide initial insights into the determinants and constraints associated with adopting TLADs within rural households in Burkina Faso. From December 2022 to January 2023, data on household characteristics and their perception of TLAD were collected through a survey of 147 rural households, of which 76 are equipped with TLAD. Respondents were selected using a combination of simple random sampling and systematic sampling methods in the provinces of Burkina Faso, with a substantial number of TLADs constructed. Descriptive statistical methods, Fisher test, t-test, and regression analysis with marginal effects were employed to analyse the data. The study results reveal that all surveyed rural households (100%) positively perceive TLADs and their by-products. Additionally, there are significant mean differences between TLAD owners and non-owner households regarding pig farming and subsidy access. Regression analysis highlights the significant positive influence of access to subsidy on TLAD adoption. Conversely, water purchase has a significant negative influence on TLAD adoption. Furthermore, TLADs positively impact household health, environment, and finances by reducing traditional fuel consumption. The main constraints to TLAD adoption primarily revolve around the lack of financial resources needed for TLAD acquisition, limited access to water and household organic waste, technical limitations related to TLAD construction, and the inefficiency of communication strategies. The findings of this study lay the foundations for a deeper understanding of the factors that promote or hinder the adoption of TLADs in Burkina Faso and could contribute to the development of more appropriate policies and measures aimed at promoting the adoption of TLADs within rural households.
