Online food shopping has emerged as a fast-growing market. However, the retail online food supply chain (ROFSC) is attracting increasing attention due to its social, environmental and financial impacts. This study aims to empirically evaluate food waste prevention and mitigation (FWPM) strategies in a real-world case study within the UK ROFSC.

Advanced methodologies are required to explore and address FWPM problems across ROFSC. Surveys and interviews were conducted with practitioners. Hard and soft data were collected from the case online retailer. Experts from an FWPM non-profit organization checked and validated the data collected.

Results revealed that inter/cross-organization integrated collaboration and visibility in the ROFSC influence FWPM. Findings established that consumers are the main source of food waste, followed by suppliers and online retailers, with 18, 11 and 1%, respectively. Worryingly, only 1% of respondents expressed that there is a strong commitment to a zero-waste strategy, emphasizing the necessity for more effective waste reduction initiatives and awareness.

The research outcome calls for further efforts by policymakers and practitioners to guide consumers toward efficient food waste management practices.

The study extends previous literature by proposing a holistic framework for reducing food waste from suppliers and consumers. The study captured interesting insights on food waste, including measuring, reasoning and destinations of online food waste.

The purpose of this study is to identify and evaluate supply chain strategies (SCSs) that drive financial performance to guide practitioners, especially in liquefied natural gas (LNG) networks, to review and adopt SCSs that drive competitiveness and value creation for investors.

Analytical hierarchy process (AHP) was deployed to prioritise SCSs according to their relative impact on financial performance in LNG networks. Interviews with experts were analysed using template analysis to establish latent drivers of financial performance specific to LNG networks.

Results support the significant role of SCSs in improving financial performance. Although findings prioritised collaborative strategy as the most important driver of financial performance in LNG networks, to fully optimise financial outcomes, all the SCSs should be implemented across LNG networks as no single strategy in isolation is a standalone driver of financial performance.

The AHP model provides a novel ranking for SCSs and measures to guide decision-makers. LNG practitioners may exploit the results to make informed decisions.

The study extends previous literature by proposing a framework and a new LNG empirical model that facilitates understanding of how SCSs contribute positively to financial performance and support practitioners in making strategic supply chain decisions.

This study investigates food waste within the food supply chain (FSC), for the case of fresh and short FSC (FS-FSC), aiming to (1) reveal the major causes of waste across FSC (2) identify the food waste mitigation strategies, (3) measure food waste impacts at each supply stream, and (4) propose practical initiatives to support decision/policymakers in strategic food waste management, especially in the case country.

This study adopts a mixed-method approach to investigating food waste, examining existing literature using template analysis. The focus is on three key elements: factors enabling food waste, its final destinations, and strategies to reduce it. The study then gathers information from a prominent regional retailer and consumers through interviews and surveys. The empirical data collected is then analysed using template analysis and descriptive statistics.

This research highlights key waste enablers across the food supply chain networks, including procurement and storage, processing, operation strategy, people, and consumers. The enablers differed in the amount of food waste produced, and the research outcome demonstrates that the end consumers were the largest contributors to the food waste generated. The changes in people's habits and tastes significantly affect the FS-FSC. Interestingly, results demonstrated that 40% of consumers utilise food leftovers as pet food.

The proposed food waste management initiatives can help companies minimise and mitigate food waste at each supply chain stage. Practitioners can use the identified causes and mitigation strategies to implement mitigation efforts and translate them into actionable plans.

The article outlines a practical approach for addressing food waste in an FS-FSC case throughout the entire chain, encompassing supply, distribution, catering, delivery, and consumption. The study not only sheds light on the primary reasons for food wastage but also provides insights into potential solutions that are not only effective but also feasible in real-world scenarios.

Despite the increasing demand for renewable energy (RE) as a low-carbon energy source, the transition to RE is very slow in many regions, including Oman, the case country for this study. It is critical to offer strategic insights to energy supply chain participants towards the sustainable transition to renewable energy (STRE). The purpose of this study is to identify viable RE sources in Oman as a case study of a GCC member country, develop a comprehensive framework of STRE, and suggest future research opportunities.

The paper addressed this problem through a country/regional study of Oman by conducting a systematic literature review (SLR) of RE-related peer-reviewed publications spanning over 21 years from January 2000 to February 2021. The qualifying articles are evaluated using template analysis qualitatively to identify viable renewable energy sources, build a holistic framework of STRE and recommend future research opportunities.

Findings confirm the potential of solar, wind, biomass and geothermal energies driven by environmental, economic and social sustainability concerns. However, results suggest that to fast-track the STRE, more emphasis should be accorded to solar and wind energies owing to the geographical composition of Oman. Findings reveal that policies and regulations, advanced and cost-effective technologies, subsidy regimes, grid connectivity and capacity, storage capacity and land availability influence the STRE. Gaps in the literature are identified from the results to clarify and suggest future research opportunities.

To the best of the authors’ knowledge, this is the first study that conducted an SLR that was evaluated using the template analysis technique to build a novel and updated framework that facilitates a crystalline understanding of STRE to guide policymakers and professionals in strategic decision-making.
