The management of offshore platforms at the end of their production phase is a complex issue for technological, socioeconomic, ecological and safety reasons. The decommissioning or reconversion of offshore platforms in the context of a circular economy (CE) will lead to new knowledge acquisition, changing values and changing behaviours towards sustainability consistent with the 'new' business objectives. Multiuse platforms at sea (MUPSs) represent an interesting solution for development of marine infrastructures, including areas in which to start and develop various creative economic activities that are in harmony with the needs of environmental protection including renewable energy, sea shellfish farming, decarbonisation plants, tourism, and recreation. Particularly, the research activity focused on a deep literature review of offshore platform decommissioning and sustainable business model (SBM) in a CE context. This allowed us to access the sustainable business model canvas (SBMC), a conceptual tool that represents a holistic view of the different managerial multiuse options and their social and environmental impacts. Besides, to test the SBMC, we adopt an empirical analysis by semi-structured questionnaires given to a sample of stakeholders in the decommissioning industry. The methodology was enriched by interviews with key informants to better investigate the business ecosystem and the feasibility of decommissioning applied to the case of an Italian offshore platform located in the Adriatic Sea. This article aims to contribute to supporting SBMs development following a holistic approach in relationship with all stakeholders and propose a multi-criteria decision-making analysis for evaluating and comparing alternative decommissioning options.

The growing complexity of environmental challenges has progressively led to the emergence of Sustainable Business Models (SBMs) able to embed economic, environmental, and social flows in a unified value network. All sectors are demanding innovative and sustainable solutions, including the oil and gas industry, which aims to address the issues about the decommissioning of offshore platforms. However, although the relevant literature highlighted the potentialities related to a multi-reuse of these structures, the effect of Sustainable Decommissioning (SD) on macro-environmental factors is still an open question. Based on these considerations, this study follows a Political, Economic, Social, Technological, Legal, and Environmental (PESTLE) analysis according to semi-structured interviews conducted with oil and gas key informants and stakeholders in the Italian context. The results of the analysis can provide a novel thinking for addressing the challenges related to a sustainable decommissioning of offshore platforms and shed light on the importance of synergistic efforts by local entrepreneurship and institutional arrangements to combine economic and environmental sustainability with social needs. This paper can contribute to the emerging field of sustainable business models related to the decommissioning of offshore platforms and suggests avenues for future research.

Purpose of the paper:The decommissioning of offshore platforms represents a significant and controversial challenge that has gained attention over the years due to its environmental, social, and economic impact. This work aims to investigate stakeholders' perceptions regarding the future of offshore platforms and to explore dimensions of sustainability related to decommissioning.Methodology: An analysis was carried out based on two rounds of empirical inquiry, a range of primary data collected through multiple-choice questionnaires and in-depth interviews.Findings: The analysis shows that stakeholders perceive reuse as an opportunity to minimise the impacts according to an environmental, economic, and social perspective. While the multipurpose platform represents an opportunity for the future, it also presents challenges. Research limitations: The study relies only on qualitative analysis techniques and on a limited sample and geographical area.Practical implications: The analysis offers several insights into the decommissioning scenario according to a sustainable and circularity perspective and contributes to the decommissioning debate by providing information about decommissioning programs, stakeholders' impacts, and future planning considerations. Originality of the paper:The study contributes knowledge to the field and useful managerial insights, highlighting stakeholders' perception in the Italian context and exploring dimensions of sustainability and main SDGs related to the issue.

The post-modern consumer is an entirely new figure and represent one of the strategic factors in terms of consumer beahaviuor and purchase intentions. The studies on grocery retailing industry is considered constantly a priority in marketing research and in managerial practice. The retailers that operate in grocery retailing, in order to propose an adequate offering system to customers, want to know what drives a consumer to make their daily purchasing and what are the factors that fosters this process. Therefore, the aim of this paper is to investigate the purchasing behaviour and explore the factors of a local context. The research is based on an explorative approach on a sample of consumers residing in Campania Region. The qualitative methodology was administrated in the three following points: 1) first, data was collected through the diary tool; 2) subsequently, were conducted in depth interviews, on the same respondents of the diaries; lastly, 3) a content analysis was carried out on the results of the diaries and interviews. The research partially confirms the evidence emerging from recent studies on Marketing Performance Measurement (MPM) in Fast Moving Consumer Goods (FMCGs) industry, referred to share of wallet's creation. Moreover, offers a new interpretation of the conceptual model on MPM, in the perspective of consumer behaviour. The research methodology is based on the individual's daily observation during his monthly purchasing process, influenced by cultural factors. The first evidences could be useful for grocery ratailing's managers to modify the business model, in the decisions on offering system, in the distribution format and in terms of pricing strategies (that is, HILO and EDLP strategy). Therefore, the future scenario is of a great interest, both for the evolutionary trends in purchasing behaviour than for the business model's innovations in grocery retailing.

The decommissioning of offshore platforms has been increasingly discussed due to its economic, social, and environmental impacts. The high complexity of this multilevel context pushes for the adoption of a service ecosystem view to explore the value propositions and actors' relations involved in resource exchanges. This study follows a mixed-method approach based on semistructured interviews conducted with oil and gas stakeholders and content analysis of the secondary data collected.The results highlight the ecosystem elements and identify the main drivers for sustainable growth in the process of the reconversion of oil and gas assets. A "meta" level is theorized to investigate how the actors' purposes can be harmonized with an ecosystem's goal to encourage the diffusion of a sustainable-oriented culture in the context of offshore decommissioning. In this sense, the study provides several insights for researchers and professionals in both the local and national governance field and the oil and gas industry.
