This article aims to optimise energy use and consumption by integrating Lean Six Sigma methodology with the ISO 50001 energy management system standard in an Irish dairy plant operation.

This work utilised Lean Six Sigma methodology to identify methods to measure and optimise energy consumption. The authors use a single descriptive case study in an Irish dairy as the methodology to explain how DMAIC was applied to reduce energy consumption.

The replacement of heavy oil with liquid natural gas in combination with the new design of steam boilers led to a CO₂ footprint reduction of almost 50%.

A further longitudinal study would be useful to measure and monitor the energy management system progress and carry out more case studies on LSS integration with energy management systems across the dairy industry.

The novelty of this study is the application of LSS in the dairy sector as an enabler of a greater energy-efficient facility, as well as the testing of the DMAIC approach to meet a key objective for ISO 50001 accreditation.

The purpose of this paper is to develop an integrated theoretical framework for energy security concept and to shed light on the policies and strategies applied by the European Union countries to confront the challenges that faces them.

The research paper uses Regional Security complexes theory, which mainly developed in Copenhagen school for security studies, that founded by Barry Buzan. This school tried to clarify the untraditional security aspects, through expanding its scope by adding new dimensions than military perspective.

Despite the consolidated efforts exerted by the European Union to assure safe levels of energy security, and their continuous pursuit to be liberated from Russian energy over dependence, but the results are still limited.

The value of this research paper stems from the fact that it encompass the theoretical aspect by shedding light on all the developments occurred to energy security concept, in addition to the Empirical side, by analyzing various European energy security challenges and their confrontation strategies.

Energy is a driving force of economic development in the modern world, while as a commodity group it holds the greatest share of the world seaborne trade. Oil, natural gas and coal are the three most important sources of energy for the European Union which, as a bloc, represents 17% of the total energy consumption. The aim of the present paper is to explore the economics and trade issues of these three major energy commodities and investigate the role of the maritime transport in the energy trade within the context of the EU-25. A number of factors are considered in order to discuss contemporary opportunities and challenges that arise in this context for the shipping business. The examination reveals the critical dependence of EU-25 energy supply on seaborne trade and the considerable reliance of the maritime transport on such commodities for the generation of shipping business within the realms of the EU-25. Among the parameters regarded as conducive to the demand of shipping services in the context of the EU energy trade are the energy demand factor, the import dependency factor, the cost effective production element, and seaborne trade related parameters while consideration is also given to environmental issues.

As the Malacca and Singapore Straits are part of the shortest route between Europe and Asia any impedance to shipping has serious commercial and strategic repercussions. What would be the consequences to tankers and container shipping if access was restricted or prevented? This issue is addressed by examining the costs of using alternative tanker routes to the Straits and the flow-on consequences of removing a mega-hub port from the container-shipping network. The analysis highlights differences between tanker shipping, where the ship itself is the prime unit of interest, and container shipping, where the door-to-door network is of paramount importance.

The purpose of the study is to analyse municipal solid waste (MSW) disposed of in Jimeta-Yola metropolis for landfill gas (LFG), methane and project viability potential.

The data was collected daily from landfills for four weeks. About 7,329.55 Mg/year of waste was analysed. These waste were separated into bio-degradable components i.e. paper and textile (263.66 Mg), non-food organic (681.45 Mg), wood and straw (189.50 Mg) and food and kitchen waste (1797.20 Mg). Non-degradable components include plastics, polythene bags, metals, sand, stones, cans etc. (4397.73 Mg). The component's characteristics such as a number of samples, weight, volume, landfill age etc. were measured. The waste, methane (CH4) and energy potential were also analysed using LFG energy cost model.

The landfills received 15 Gg/year of MSW and emit 0.31 Gg/year of LFG having CH4 content of 82.95 Mg in 2016. These can produce 33.78 GWh of heat energy equivalent to 10.14 GWh of electricity analytically. Therefore, between 2016 and 2022, about 2.24 Gg CH4 and 5201.32 MWh of electricity were wasted. Henceforth, proper management of these waste substances can produce 186.4 Gg CH4 which will generate 432.52 GWh of electricity. The most economically viable project is an electricity project generating 418 kW/year at a sale price of $1.14/kWh (58.38/kWh) and a payback period of 11 years.

Raw LFG collected can be used in heating brick kilns, boilers, furnaces and greenhouses. When treated, the LFG can produce renewable natural gas (RNG), which is used in energy generation and various domestic, vehicle and industrial applications.

The analytical energy generation can provide gross revenue of ₦19.46bn at an average of ₦192.71million/year. Using Landfill Gas Emissions Model (LandGEM) model, the gross and net revenue will be $0.42m and $0.28m yearly, respectively. The project can provide jobs and economic boost to the immediate community through associated ripple effect.

The research is a pre-feasibility study for LFG to gas or electricity projects in Jimeta-Yola. The study contributed to the body of knowledge as a source of literature for further studies locally and globally.

The purpose of this study is to find out the future development of the Panama Canal after opening of the new waterway (third set of locks project), in terms of the change of cargo throughput, further deployment of fleets by the shipping companies and competition for the canal.

The research of this paper is based on an empiric study by collecting the relevant data from annual report of the Panama Canal Authority, publications related to the same field. Graphs pertaining to toll revenue also are made based on statistical data provided by the Panama Canal Authority.

The findings show that the opening of the new waterway of the Panama Canal generates more toll revenue for Panama government by allowing mega-vessels to transit, expediting further economic development of the country largely from behind. At the same time, shipping operators also can enjoy earning more revenue by deploying New Panamax vessels transiting the Canal.

Ingenuity in tabling the users of the Panama Canal by incorporating the logo marks of the shipping companies/implication is drawn through empirical analysis to provide the shipping companies and ports authorities concerned with more understanding toward the very significance of the new waterway expansion of the Panama Canal.

This paper aims to explore what environmental justice (EJ) can offer to sport management research and highlights the urgency for sport management scholars interested in environmental and ecological issues to engage with EJ as an important research agenda.

This paper is primarily a position and conceptual paper. Drawing from multidisciplinary literature (e.g. critical human geography, environmental sociology, Indigenous studies and postcolonial studies), it provides an overview of the major conceptualizations of EJ and discusses important premises for sport management researchers to engage with EJ topics.

EJ offers opportunities for sport management researchers to form stronger analyses on existing racial, socio-economic, and gender-related inequities manifest in the sport industry. The incorporation of EJ can strengthen the emerging sport ecology research in sport management and offer opportunities for sport management researchers to form stronger analyses on existing racial, class and gender-related inequities manifest in the sport industry.

It provides a critical and original intervention to the sport management literature. EJ's emphasis on power and its position at the convergence of social movements, public policy, and scholarship hold important potential for sport management researchers to advance scholarship with “actions,” addressing environmental harms and seeking practical solutions for enhancing communities' well-being.

This study investigates how cruise corporations, which have shown consistent and high growth rates in recent years, address the Sustainable Development Goal 17 (SDG17) “Partnership for the Goals” to meet the UN 2030 Agenda. This study aims to fill the existent gap in the literature, as also highlighted by practitioners in the First Research Conference on Tourism, through the lens of stakeholder theory.

This study focuses on the analysis of partnerships and collaborative governance of cruise corporations’ endeavours to meet the UN 2030 Agenda. This study is supported by the sustainability disclosure framework and stakeholder theory, based on the dependence of resources and descriptive and instrumental approaches to describe, analyse and map, through multi-stakeholder partnerships, the sustainability initiatives and practices adopted by cruise corporations. A systematic manual content analysis has been developed on sustainability reporting published by corporations.

According to the descriptive and instrumental approaches and the dependence resources construct of the stakeholder theory, this study highlights the typology and nature of partnerships with SDGs, and their strategic role in achieving them, although cruise corporations do not highlight in their sustainability reporting the measures of effectiveness regarding the relationship between single partnerships and targets reached for each SDG.

Recommendations at the managerial level are put forward to support cruise corporations’ initiatives and practices to meet UN 2030 Agenda. This study suggests to governors of corporations the cooperation between the cruise industry and institutions at the local, national and international levels for promoting institutional interventions at the infrastructure and economic level.

This study provides further insights into the under-researched topic of sustainability disclosure within the cruise industry, adopting the lens of stakeholder theory from the partnerships’ perspective. To the best of the authors’ knowledge, this is the first study to adopt the analysis of the SDG practices under the lens of the stakeholder theory, based on the dependence of resources and descriptive and instrumental approaches to identify, map and analyse the multi-stakeholder partnerships as an enabling key to meet UN 2030 Agenda in the cruise industry.

Due to the globalization of trade, hundreds of millions containers pass every year through world ports. Such a situation is extremely challenging in terms of securing freight transport operations. However, costs and lead-times are still very important components of supply chains' performance models. Therefore, the drive for enhanced safety and security cannot be made at the expense of these other two factors of competitiveness, and the processes implemented by the global supply chain links, including the maritime port one, should tend to a joint optimization of trade facilitation and operational safety / security.

The research on which this paper feeds back falls within the frame of this mixed performance requirement. More specifically, the paper presents a decision-support system dedicated to managing the risks associated with land and maritime container transportation; this system is based on the modeling of the knowledge of a group of experts, and covers the three phases of risk identification, assessment and avoidance / mitigation.

This study aims to analyze information on vessel traffic between the two Koreas with a probability distribution for each route/vessel type. The study will then conduct an estimate for maritime transport patterns of inter-Korean trade in the future. To analyze the flow of inter-Korean coastal shipping, this study conducted visualization analysis of shipping status between North and South Korea by year, ship type, and port using navigation data of three years from Port Logistics Information System (Port-MIS) sources during 2006 to 2008, which saw the most active exchanges between the two governments. Also, this study analyzes shipping status between the two governments as a probability distribution for each port and provides the prospects for future maritime transport for inter-Korean trade by means of Bayesian Networks and simulation. The results of the analysis are as follows: i) when North-South routes are reopened, the import volume for sand from North Korea will be increased; ii) investment in the modernization of ports in North Korea is required so that shipping companies can generate profit through economies of scale; iii) the number of the operating vessels including container ships between the two governments is expected to increase like when the tensions and conflict on the Korean Peninsula was release, especially between Busan port in South Korea and Nampo port in North Korea; and iv) among container ships, transshipment containers imported and exported through Busan Port will be shipped to North Korea by feeder transportation.
