Goal: The need to discuss reverse logistics processes with a detailed and analytical approach, aiming at improving the reverse channel efficiency is notorious in the literature. Therefore, this research aimed to analyze and describe in detail the activities that make up the reverse logistics processes and, in addition, to propose a conceptual framework for a better understanding and definition of RL processes. . Design / Methodology / Approach: This was achieved through a systematic review, which considered 3.517 papers, analyzing the RL concepts, definitions and objectives, as well as identifying its processes and activities. The activities were categorized as information (I-RL process) or materials (M-RL process) related. Results: This research provides an entire RL activities blueprint. This approach promotes greater transparency, allowing to identify stages most impacted on the reverse channels, besides standardizing logistical procedures and also allowing to insert control points for measuring performance. Limitations of the investigation: It is possible for a paper that focuses on one of the activities of the framework not to have been shown during the database if it doesn’t mention the keywords “reverse logistics”, “green logistics” and “sustainable logistics”. Practical implications: The concepts of reverse logistics activities presented in the framework can be implemented in reverse supply chains, serving as a basis for organizational strategies for managers involved with such processes. Originality / Value: The authors of this paper believe that the results achieved can greatly contribute to the expansion of debates in the RL area, as well as serve as a basis for managers involved with RL processes.

Research on implementation of Product-Service Systems (PSS) in manufacturing companies has grown steadily and many methods have been published. This paper aims to identify and analyses existing methods on the implementation of PSS through a systematic literature review, focusing on methods with information considered enough for effective application. It was identified 1716 papers published among January 2006 and December 2018. Forty-six methods were identified; of which only 5 met the criteria established in the research for practical application. There is no convergence in the literature for indication of a predominant method, or even a guide to select the appropriate method for the business context. The approaches, procedures and characteristics of the methods are equivalent. No predominance of some over the others, about better results or efficiency, was observed. Despite the large volume of information identified, there is a gap in the literature, which is the lack of papers that guides effectively to develop a PSS and with detailed information for implementation.
