The main objective of this paper is to utilize a multi-criteria analysis (MCA) to evaluate Waste-to-Energy (WTE) technologies and identify constraints when examining the placement of a WTE facility. From this, the focus is best summarized by determining the optimal WTE technology in developed countries and how the process would change if implemented in developing nations. In this study, incineration, gasification, and pyrolysis technologies were reviewed and evaluated. The MCA evaluated the different WTE technologies based on a variety of criteria considering environmental, financial, social, technical, and waste quality and quantity. Different weighted factors were used for the two MCAs and different alternative weighted factor scenarios were produced to perform a sensitivity analysis on the results. Overall, pyrolysis was found to be the preferred option for the developed and the developing nation in all scenarios. For developed countries, the highest difference in the overall index score (7 %) was found in incineration between the baseline and scenario 4. In developing countries, the highest differences in the overall index scores were found in scenario 3 for incineration (9 %) and pyrolysis (10 %). Although pyrolysis had the highest overall capital cost due to it being the newest technology, the environmental, social, associated risk, and waste benefits were seen to be more significant on the findings.

The clear differences between developing nations and developed nations have posed an enormous problem in trying to design a “one-size-fits-all” theory of Electronic Commerce (EC) adoption. Most prior studies have proposed that generalizing findings of developed countries to the context of developing countries are of worry (Rahayu & Day, 2015; J. Tan, Tyler, & Manica, 2007). Table 1 shows the ICT Development Index (benchmarking tools to monitor information society developments worldwide) of some countries that have hosted the earlier literature on EC International Telecommunications Unions (ITU, 2017). These statistics may well indicate that businesses in developed countries and developing countries vary with regard to information technology and EC context<strong>.</strong> The latest ITU report in 2017 on ICT Development Index, ranks Ghana as the 112th country regarding ICT development in 2016, which shows a slight decline in the ranking compared to 111th in 2015 (the IDI value increased from 3.75 in 2015 to 3.99 in 2016). This may suggest that Ghana does not have appropriate infrastructure for effective e-business compared to countries like Singapore, China and USA.

With a major proportion of research on Electronic Commerce (EC) undertaken on large corporations, and focused primarily on developed countries, little is known about the determinants of EC in Small and Medium-sized Enterprises (SMEs) of developing nations. This chapter explores the extent of EC use by SMEs, and provides some empirical evidence of how internal factors of firm and owner are influencing EC adoption among smaller businesses in Malaysia. The methodology and results of this study may be applicable to other developing countries. Findings confirm the low level of participation in EC by SMEs. The age of enterprise, as well as the owner’s gender and education were found to be significant in determining the level of EC adoption. Though some of the results contradict those of previous studies, they may have a greater implication for government authorities in drawing up guidelines, approaches, and formulating more effective frameworks to promote EC use among SMEs in developing countries.

The Sustainable Development

&lt;p&gt;Water is a key element to the economic development and plays vital role in various activities including commercial, households, services, water-landscape, and water transport etc. A good water environment in cities has been achieved in developed countries (for e.g. Japan) through implementation of central wastewater treatment and sewerage systems. However, the development of sustainable water management and introducing a new sewage management method is challenging for the cities of developing nations in Asia in terms of having high capital, energy consumption and the technologies. This paper is evaluating the role and importance of sustainable development of water management methods and systems. Our findings suggest that the developed and developing countries must come forward and work together for the sustainable development of the cities in developing nations particularly by providing skills and efficient technologies for the improvement of water quality and wastewater treatment systems. For this, the progress of a systematic supported decision-making tool to allow investors and consumers to contribute to the development of sustainable water management methods and sewage treatment systems through bi- and multilateral investments. In addition, the active involvement of multi-stakeholders (citizens, local municipalities, industries, policy makers) with financial and non-financial institutions would help to create a &amp;#8220;sustainable cities&amp;#8221; in developing countries.&lt;/p&gt;

The digital economy is a key catalyst for the economic growth of developing nations. However, because developing nations often lack the resources needed to grow in this area, it is essential for a developing nation to focus on identifying obstacles and to strategize toward long-term improvement. We study the current state of digital economies among developing nations, and evaluate the causes of their limitations. Specifically, we use the Russian Federation’s strategy for the development of their digital economy as a case study for identifying common issues that developing nations face in this area.

The concept of smart cities has become a buzzword in most developing countries. Most professionals within developing countries are quick to adopt this idea in their every day discuss on developing the state of their nation, without actually considering what this concept means to the average individual on the streets. Even lesser consideration is given to the readiness of these developing nations in terms of adopting the concept of smart cities. It is based on this notion that this study, through the review of existing studies, assessed the readiness of cities in Nigeria in adopting the concepts needed for achieving smart cities. The study gives an insight on the challenges impeding the attainment of city smartness in the country. It was observed that solving the problems caused by rapid urbanization within cities is the first step towards making these cities "smart ready". Therefore, if cities in Nigeria are to attain city smartness, first looking inward and solving the endemic problems within these countries is necessary before adopting concepts of smart cities that have been mastered in developed countries. Although the submissions of this paper form part of a much larger ongoing study, it contributes to the body of knowledge as it brings to light the challenges that must be solved if cities in Nigeria are to ever become smart.

The dominant technology for large Waste-to-Energy (WTE) facilities is combustion on a moving grate of “as-received” municipal solid wastes (MSW). However, there are circumstances where a low-capacity plant (<100,000 tons per year) is required. This study examines the technical, economic, and environmental aspects of some small-scale WTE technologies currently in operation. The Energos technology was developed in Norway, in order to provide relatively small communities with an economically efficient alternative to mass-burn incineration with equally low emissions to the atmosphere and flexibility in feedstock. All operating plants treat MSW plus additional streams of commercial or industrial wastes. Prior to thermal treatment, the materials are shredded in a high-torque, low-rpm shredder and ferrous metals are removed magnetically. The feedstock is partially oxidized on a moving grate in the gasification chamber where the fixed carbon is completely burnt off. The volatilized gases are fully combusted in a second chamber and the heat is transferred to a heat recovery system for steam generation. The Energos gasification technology is currently in operation at six plants in Norway, one in Germany, and one in the UK. As expected, the capital cost per ton of annual ton of capacity increases with decreasing plant capacity, while there is a linear relationship between energy recovery and capacity. Some other small-scale technologies are investigated in this study and will be reported at the NAWTEC meeting. Low capacity (<80,000 tons) WTE facilities require a relatively small footprint (1.5 to 2 acres; <1 hectare) and it is believed that these facilities can be built at a capital cost per ton that is as low, or lower, than that of large mass burn WTE facilities.

Developing countries have their own particular political, economic and cultural circumstances. There are, therefore, no unique solutions. However there are some factors which are common to all or most of them, namely the lack of human and financial resources and in most cases an absence of a political commitment to the advancement of science. Such situations are in a sense not peculiar to developing nations because in some developed countries astronomy has a ‘developing’ status. Even in countries where astronomy is well established, the commitment and allocations required to maintain the status quo need to be continuously addressed. Hence strategies for fighting this “constant battle” are relevant to all astronomers of the world, while being especially vital to those in the developing world.

Biotechnology entrepreneurship is now associated with a sustained flow of innovations and tools, offering dramatic improvements in human health and a compelling value proposition for health care and agricultural consumers as a result of entrepreneurial orientation being applied. Biotechnology entrepreneurship in developed and developing nations like that of Japan, China, India and that of Nigeria and even some Asian countries is relatively new and distinct field of entrepreneurial endeavors. Most current empirical researches are conducted in the developed economies and cannot be directly extrapolated to the developing economies. This research used a qualitative research method. The data collection methods were interviews, documents review and observations, which improved the quality of the research through data triangulation. In addition, some factors that influence the process of biotechnology entrepreneurship in developed and developing countries were identified as regulation, funding, infrastructure, skills, entrepreneurial and commercialization capabilities, etc. Biotechnology entrepreneurship in developed countries predominantly uses the “system approach” and the “individual approach” in developing nations. The process of biotechnology entrepreneurship in developed countries differs from the process in developing nations due to the differences in the environmental factors that influence biotechnology entrepreneurship, and management strategies, in these economies.

Abstract It is critical for reliable infrastructure planning to address the Food-Energy-Water-Waste (FEW2) nexus at system level. This paper presents the applicability of the systematic modelling platform resilience.io across water, energy and waste sectors with focus on waste-to-energy pathway, aiming to establish the optimal FEW2 nexus based on economic and environmental indicators. A rich array of technology options, including water production facilities, clean energy technologies and waste-to-energy conversions are evaluated to meet the demand of water and energy (mainly gas and electricity), and the treatment requirement of waste and wastewater. A case study of Hunter Valley, the largest region in Australia, is presented in this study, featuring the supply and demand context of developed countries. A full set of scenarios, including business-as-usual (BAU), water and wastewater, power plant decommission, waste-to-energy and policy intervention, is created to present FEW2 nexus from the perspective of individual nodes and the whole system. The results signal the benefits of biogas and syngas generation from anaerobic digestion and gasification for waste-to-energy pathway, alongside findings in water and energy sectors. The outcome of this analysis can then form the foundation of regional planning involving relevant stakeholders, with the modelling tools supporting scenario evaluation and collaborative learning to reach consensus in view of different performance indicators.

For decades, reputation of the construction industry has been tainted by poor cost performance caused by project cost overrun. In addition, studies by scholars worldwide have also found cost overrun to be more serious in developing countries compared to the developed countries. Despite the numerous researches addressing the issue of cost overrun in the construction industry through the years, the issue remains. Acknowledging that maintaining good cost performance is a key factor of project success and that the issue has persisted for decades, this study aims to explore the distinction of cost overrun studies that has been conducted between developed nations and developing nations. In achieving this aim, a systematic literature review is performed by following the integrative steps of PSALSAR (Protocol, Search, Appraisal, Synthesis, Analysis and Report) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) for screening and selecting the retrieved studies. The synthesis and screening of literatures have yielded with 152 articles which are then classified into their countries, developed countries (44) and developing countries (108). The results indicated a significant difference in the domain of research on cost overrun between the 2 nations. Despite the numerous studies on cost overrun in the developing nations compared to developed nations, the majority of the studies are not directed to any specific type construction while developed nations have moved forward to focus on more specific projects. The project with the highest attention in the developed nations is transport infrastructure construction projects, particularly rail infrastructure projects. The findings of this study have shown that there have been broad studies conducted on cost overrun in both developing nations and developed nations. However, there is a slight lacking in comprehensiveness of cost overrun studies in the developing nations, perhaps future studies on cost overrun in developing nations can be directed to more specific areas of construction projects such as those that have been performed by researchers of the developed nations.
