Abstract

Purpose

Kumasi Metropolis, the second-largest city in Ghana is known to be bewildered with challenges relating to waste management. As a means of solving the waste management challenge, several suggestions are often made for the establishment of a waste-to-energy plant to manage the disposal of waste and generation of income. There have been no studies conducted to determine how economically viable such plants will be. This study aims to examine the economic viability of waste-to-energy generation in the Kumasi Metropolis to find out how economically viable such an approach will be.

Design/methodology/approach

To achieve this, a simple debt-equity ratio business model based on discounted cash flow technique was applied to estimate the internal rate of returns (IRR) as a measure of the economic viability and profitability of a modelled 50 MWH waste-energy generation plant in the Kumasi Metropolis. The analysis was performed using the RetScreen Expert Software.

Findings

The results show that the IRR and benefits cost ratio of the facility were 36% and 5.8%, respectively, indicating high levels of profitability and economic viability. The study concludes that waste-to-energy generation will be an economically viable venture in the Kumasi Metropolis.

Practical implications

It is, however, important for users of the findings of this study to take caution of the fact that the various assumptions although based on current knowledge and expert opinion may vary with time; therefore, the sensitive analysis on price and costs should always be considered. Practically, this study will contribute to solving the waste management situation in most cities, as well as generating revenue and helping close the energy deficit most developing countries are grabbling with.

Originality/value

The unique contribution of the study to knowledge is that it has professed an alternative analytical and methodological approach to measuring the financial viability of waste-to-energy plants in situations where there is none in the geographical jurisdiction of the proposed project.

Abstract

Purpose

Globally, waste management has been a topical issue in the past few decades due to the continual increase in municipal solid waste (MSW) generation that is becoming difficult to handle with conventional waste management techniques. The situation is much more pronounced in economically developing countries where population growth rate and urbanisation are becoming uncontrollable. The purpose of this study was to assess the potential for waste to energy generation in the Kumasi metropolis, the second-largest city in Ghana.

Design/methodology/approach

To address the objectives of the study, a quantitative research approach, namely, the questionnaire was adopted. The data analysis was done using the statistical package for social sciences version 25, including both descriptive and inferential statistics to give an in-depth meaning to the responses from the participants.

Findings

The results showed that several factors hinder waste to energy technology in Ghana; key among them was high capital cost, high operational cost and lack of governmental support and policy framework. The results also revealed that 1 m3 of biogas generated from MSW in Kumasi could generate 36 MJ of energy, equivalent to 10 kW/h.

Originality/value

The unique contribution made by the paper is that it combines expert opinions, empirical data that included time series data and opinion of key actors in the waste management chain in assessing the potential for waste to energy generation in the Kumasi metropolis of Ghana.

Abstract

Purpose

Egypt has set plans to transform into a green economy which requires major reforms in the waste sector as one of the most vital sectors crucial for this transformation. This study aims at inspecting the current status of the Egyptian waste sector to highlight the major policy reforms needed. Furthermore, it assesses the economic viability of establishing waste-to-energy (WtE) projects under the current regulations that govern the sector.

Design/methodology/approach

The study employed an inductive analytical approach to scrutinize the institutional and regulatory framework of the waste and WtE sectors. Furthermore, a novel techno-economic analysis was conducted to assess the profitability of a WtE plant that employs moving grate incineration technology.

Findings

The analysis of the waste sector revealed its deteriorating state and the dire need for immediate restructuring through more stringent regulations to establish an integrated waste management system (IWMS) that incorporates WtE technologies as well as a number of corrective actions that would help enhance the sector. Additionally, the techno-economic analysis revealed the need to amend the current WtE regulation to comprise a gate fee as an indispensable revenue stream for WtE projects.

Originality/value

This study is one of a few studies that uses a new technique of analysis to explore the potential role that WtE projects can play in Egypt as a part of an IWMS that aims at transforming the waste sector into a resource sector while providing a renewable and sustainable source of energy.

Abstract

Purpose

For India, with its low agricultural productivity and huge population, land acquisition has always been a serious policy challenge in the installation of land-intensive power projects. India has experienced a large number of projects getting stalled because of land conflict. Yet, there is a paucity of literature pertinent to India that tries to estimate future land requirements taking into consideration of land occupation metric.

Design/methodology/approach

In the present study, the dynamic land transformation and land occupation metrics of nine energy sources, both conventional and renewable, are estimated to further determine the magnitude of land requirement that India needs to prepare itself to fulfil its Intended Nationally Determined Contribution (INDC) commitments. This is illustrated through two different scenarios of energy requirement growth rates, namely, conservative and advanced.

Findings

This analysis suggests that, while nuclear energy entails the lowest dynamic land transformation when land occupation metric is taken into account, waste to energy source possesses least land requirement, followed by coal-fired source. Hydro energy source has highest requirement both in terms of dynamic land transformation and land occupation. It is also seen that land requirement will be 96% and 120% more in INDC scenario than business as usual (i.e. if India continues with its current share of renewables in its energy portfolio in 2030) considering a conservative and an advanced growth rate, respectively.

Research limitations/implications

Some policy recommendations are provided that may aid policymakers to better address the trade-off between clean energy and land and incorporate it into policy planning. This study has not been able to consider future technical efficiency improvement possibilities for all energy sources, which can be incorporated in the proposed framework for further insight.

Originality/value

This paper provides a framework for estimation of future land requirement to fulfil India’s INDC energy plans which is not available in existing literature. The authors confirm that this manuscript is an original work.

Abstract

Purpose

This study aims to explore the reasons behind the lengthy delays in completing a single public-private partnership (PPP) project in Indonesia and investigates how the transaction costs play a significant role in hindering the project’s success.

Design/methodology/approach

To broaden insight into the transaction cost theory, the authors used a single case study approach to provide a more in-depth analysis of a context whose complexity can be fully explored. As the primary data sources, 16 face-to-face semi-structured interviews were conducted with the stakeholders directly involved in the project’s initiation, design and execution.

Findings

This case study demonstrates that transaction cost issues, both political and economic, play a significant role. This study has identified four main problems associated with transaction costs hindering project success, namely, executing agencies’ lack of knowledge and experience, lack of coordination for such a complex governance structure that links too many stakeholders and the financial and political risk that increase the uncertainty and public distrust.

Research limitations/implications

This study contributes mainly to the PPP and transaction costs economics literature, providing empirical evidence on why major PPP projects may fail to be procured. The Greater Bandung waste to energy (WTE) Project case demonstrates that transaction costs, both political and economic, have played a significant role in the lengthy delay of the PPP project.

Practical implications

As the project involves many transaction cost issues, mapping the failure factors at the project sites can significantly contribute to the practitioners/stakeholders involved in the PPP WTE projects. Therefore, this study provides a lesson to the policymakers at all levels interested in PPPs to consider the issues of transaction costs related to the PPP projects. It can be used as guidance as well as a reference for future PPP WTE projects in Indonesia.

Social implications

Mapping the failure factors also signifying the response of the public in the PPP WTE projects undertaken. As the citizens become more rule-conscious and rights-conscious, they demand the opportunity to participate in creating rules and project plans. If the project failed to consult with affected communities and undermined democratic accountability, the angry citizens will confront the government to cancel the project. Therefore, political and economic influences for public attitude play significant roles in making the PPP WTE projects successful.

Originality/value

This study provides insight into the transaction cost issues that have hindered the completion of Indonesia’s PPP WTE project over the past 15 years. Additionally, the project feasibility analysis should include an understanding of transaction costs for partnering in PPP.

Abstract

The zero-waste term in municipal solid waste management has been the utopian objective of every waste management authority in the cities in developing countries, even though it comes with different perceptions, which are sometimes misguided. People can produce no waste unless they live with no consumption. The zero-waste term does not mean that we produce no waste, rather we dump no waste at the landfill site. It means we dispose of nothing at a landfill site since the issue of landfill site can be a culprit of waste management, for its reiterating city land demands that generate “headaches” to city authority because of NIMBYism (Not In My Back Yard issue). No one accepts living voluntarily next to a landfill site as it creates more harm than harmless. With zero waste at the landfill site in mind, the waste management authority attempts to deal with the complexity of municipal solid waste management, by reviving each element of the waste management stakeholders to concertedly move on to deal with waste. Individual households and communities, without which waste management will not be successful, were positioned as the main thrust of waste management. A multipronged approach was implemented with all stakeholders, i.e., lawmakers, regulators, waste producers, implementers, and pressure groups, appearing with different functions but a common point: zero waste at the landfill site. A stakeholder with a large capacity, i.e., local government focuses on creating a large project that has a large impact on overall waste management; private sectors may contribute to establishing recycling centers, and waste-to-energy projects. Meanwhile, the individual households, which are large in number but have a small capacity, establish community-based activities, i.e., waste banks. This chapter attempts to provide the overall picture of municipal solid waste management in 14 cities in developing countries toward their goal of zero waste at landfill sites.

Abstract

Purpose

This paper highlights how biological waste materials can be used for generating the much needed energy and obtaining nutrient-rich compost for agriculture through anaerobic digestion (AD). The paper further highlights the importance of small and medium enterprises (SMEs) in using AD for converting waste to energy (WTE), leading to many environmental benefits as well as clean energy generation. It would help to reduce pollution, water acidification and carbon emissions that eventually lead to climate change.

Design/methodology/approach

The researchers undertook an in-depth study to highlight the role played by an SME in converting WTE and helping towards achieving circularity. An exploratory case-based approach was used to understand value leakage for an AD plant operating on WTE principles in the UK. The plant is still currently active, and it is located in the Midlands, England. Fifteen semi-structured interviews were undertaken with different stakeholders.

Findings

This paper reveals the importance of WTE and the significant role played by AD in converting food waste into useful matter. It reports further into the value leakage issue faced in the AD plants. It demonstrates the importance of technological innovation in SME to capture value leakages in a circular model. Most importantly, it demonstrates how SMEs gain competitive advantage and generate value proposition, while they aim for zero waste to landfill objective.

Research limitations/implications

The research involves a case study based on an SME, operating on a circular business model. It will be worth investigating how other businesses could gain competitive advantage. For SMEs interested in AD for WTE, this paper introduces further technological innovation to the AD process to leverage further potential for reuse of waste liquid. Any SMEs entering WTE market ought to take into consideration such design implications.

Practical implications

The paper reveals how the use of waste by SMEs would lead to many environmental benefits as well as clean energy generation. It would help to reduce pollution, water acidification and carbon emissions that eventually lead to climate change. It is useful for addressing the needs of waste food producers and is a cheap raw material for generating energy. The benefits to the public are that it reduces the need for landfill and increases recycling.

Social implications

The WTE is an effective way of making use of last-stage waste.

Originality/value

Despite SMEs being the powerhouse of the European economies, there is limited research investigating how circular economy (CE) could unlock their potential. Moreover, development of AD in the UK has lagged behind other EU countries. We highlight value leakages and argue how technological innovation should be used to close the value chain loop in the WTE production process. This paper, therefore, demonstrates the important role of an AD process, which involves decomposition of biodegradable materials. It shows that AD is an economically viable and environmentally friendly process of obtaining clean energy at low cost.

Abstract

Purpose

Many waste-to-energy (WTE) plants are constructed and operated using the public-private partnership (PPP) mode in China. However, risk events of PPP WTE incineration projects sometimes occur. This study aims to clarify the relationship of risks in China's PPP WTE incineration projects and identify the key risks accordingly and risk transmission paths.

Design/methodology/approach

A risk list of PPP WTE incineration projects was obtained based on literature analysis. Moreover, a hybrid approach combining fuzzy sets, decision-making trial and evaluation laboratory (DEMATEL) and interpretive structural modeling (ISM) was developed to analyze the causality of risks, explore critical risks and reveal the risk transmission paths. The quantitative analysis process was implemented in MATLAB.

Findings

The results show that government decision-making risk, government credit risk, government supervision behavior risk, legal and policy risk, revenue and cost risk and management capacity risk are the critical risks of PPP WTE incineration projects in China. These critical risks are at different levels in the risk hierarchy and often trigger other risks.

Originality/value

Currently, there is a lack of exploration on the interaction between the risks of PPP WTE incineration projects. This study fills this gap by examining the key risks and risk transfer pathways of PPP WTE incineration projects from the perspective of risk interactions. The findings can help the public and private sectors to systematically understand the risks in PPP WTE incineration projects, thus enabling them to identify the risks that need to be focused on when making decisions and to optimize risk prevention strategies. The proposed hybrid approach can offer methodological ideas for risk analysis of other types of PPP projects.

Abstract

Purpose

It is no surprise that garbage is not garbage for some. It is money. This is why garbage has been overestimated to a point that money allocated for waste-to-energy (WtE) projects feed individual pockets. Many countries have already adapted WtE as a successful solution for both energy and waste crisis. Although in Sri Lanka six WtE projects were promised, the government abruptly decided that it would not have any more projects other than the two plants that were under construction. The purpose of this paper is to analyse barriers to the implementation of WtE projects in Sri Lanka.

Design/methodology/approach

An exploratory case study was selected as the research strategy to achieve the research aim. In total, two WtE megaprojects, which have been initiated implementation in Sri Lanka, were used as cases. A total of 12 semi-structured interviews with four personnel from each case and four government officials were used as the data collection technique. Data analysis was carried out using code-based content analysis. The barriers were extracted through analysis of case findings using an abductive analysis. The strategies to mitigate identified barriers were formulated based on attributes highlighted through case study findings and further validated through the opinions of three experts.

Findings

Barriers were analysed using the PESTEL framework to get ample insight into barriers that impact on the implementation of WtE projects in Sri Lanka. Less support from the government due to their less awareness on WtE, high investment and operational cost, lack of expert knowledge on WtE technologies in Sri Lanka, absence of a proper regulatory framework for implementation WtE technologies, lengthy process and delay in getting approvals from government process, poor attitudes of public and their protests due to the less awareness on WtE are the foremost barriers identified in this study. Further, strategies were proposed based on the empirical research findings to overcome barriers to facilitate the successful implementation of WtE projects in Sri Lanka.

Research limitations/implications

So far only two WtE megaprojects have been initiated the implementation in Sri Lanka. Therefore, the scope of the study was limited only to those projects. Moreover, the type of waste considered in this study is municipal solid waste (MSW), which has become a bigger problem in Sri Lanka.

Originality/value

The current study unveils an analysis of barriers for implementation of WtE projects in Sri Lanka, including strategies for mitigating identified barriers. The findings would enable relevant stakeholders, i.e. policymakers, industry practitioners, investors, government bodies and researchers to make informed decisions on implementation of WtE projects and thereby promote successful implementation of WtE projects in Sri Lanka.

Abstract

Purpose

This study aims to explore the critical influencing factors that lead to the site selection failure of waste-to-energy (WtE) projects in China under the influence of the “Not In My Back Yard” (NIMBY) effect, which can provide references to improve the decision-making process of similar projects in the future.

Design/methodology/approach

The fuzzy decision-making trial and evaluation laboratory (DEMATEL) method was used to propose an analytical framework for exploring the critical influencing factors affecting the site selection failure of WtE projects. The causal relationship between different influencing factors is finally determined on the basis of the opinions of 12 experts from universities, government departments, consulting units, planning and design units, construction units and WtE enterprises.

Findings

Results showed that six crucial factors resulted in the site selection failure of WtE projects from the NIMBY effect perspective: “Insufficient public participation,” “Near the place of residence,” “Nonstandard government decision-making processes,” “Low information disclosure,” “Destroys the surrounding environment,” and “Imperfect compensation scheme.”

Originality/value

Results can determine the priorities and causal relationships among the various influencing factors. The decision-making optimization suggestions can provide reference for decision- makers, thereby possibly promoting the scientific and standardization of site selection decision process.
