Abstract: This paper investigates patterns of sustainable behaviour in the use of sewage sludge (STW) in agriculture. The object of the study is a literature analysis of farmers‘ behaviour in using waste as a resource in agricultural activities. At the center of the analysis is the object of study - the behavioural patterns through which pro-environmental business attitudes and/or practices related to the use of sewage sludge are formed and manifested, considered in the broader context of sustainable waste management in agriculture. The main objective of the study is to identify and analyze the patterns of behaviour that determine choices and influence farmers‘ decisions regarding the sustainable use of SSSW sludge as an alternative resource and as a tool for sustainable agriculture. The theoretical framework builds on four established behavioural models: the Theory of Planned Behaviour, the Theory of Expected Utility, the Theory of Collective Action and the Diffusion of Innovations Theory. Each of these models provides an analytical toolkit for interpretation. Through their application, a better understanding of the individual-motivational, social and institutional factors influencing farmers‘ environmentally responsible behaviour is sought. The analysis aims to provide a conceptual basis for developing policies and practical mechanisms to promote sustainable waste recovery practices in the agricultural sector. The research methodology includes a critical review of existing scientific literature and a comparative analysis of foreign experiences in order to outline the behavioural profile of the sustainable farmer in the context of the circular economy. The research objectives include:- A review of relevant literature with respect to leading behavioural theories;- Analysis and clustering of behavioural models applicable to the context of sustainable waste management;- Presentation of international examples and best practices illustrating the actual application of these models to the management of sewage sludge in agriculture;- Draw conclusions on the applicability of the models in the European and Bulgarian agricultural context. The expected results are related to the derivation of a theoretically-integrated model that can serve as a basis for promoting sustainable behaviour in the use of sewage sludge in agriculture. Also to contribute to a better understanding of green transformation processes in the sector by shaping adequate policies, incentives and educational measures in this regard. Consequently, also to draw the basis for adapting successful European practices to the Bulgarian agricultural reality.
