Abstract

Purpose

Increased disposal costs and reduction in number of landfills have created a need for implementing effective waste management in the construction industry. As every construction project is unique in its way of development, benefits from the waste management may also differ from project to project and thus project characteristics should be taken into consideration when implementing the strategy. This study seeks to investigate how different project characteristics affect perception on benefits, from construction waste management, based on the survey results from 66 industry experts.

Design/methodology/approach

A literature review was conducted to gather information on project characteristics and its classification, construction waste management, waste management plan and its benefits. Subsequently, a set of questions was formulated to gain insight and opinion on the selection of project characteristics and particular benefits of construction waste management. A set of questions pertaining to different project characteristics linked with benefits of waste management was sent to each of the personnel for their views.

Findings

The results of this study establishes that the key materials used in projects, project size in terms of total installed costs, and project type have perceptual impacts on benefits from construction waste management.

Originality/value

Understanding how project characteristics will affect the benefits can help the construction industry to identify projects to which the waste management should first be applied, maximizing its benefits.

Abstract

Purpose

The purpose of this paper is to examine the medical waste management practices of a hospital in Southern Africa.

Design/methodology/approach

A case study methodology was utilised.

Findings

The results revealed that the hospital does not quantify medical waste. Segregation of medical waste into infectious waste and non‐infectious waste is not conducted according to definite rules and standards. Separation of medical waste and municipal waste is however practiced to a satisfactory extent. Wheeled trolleys are used for on‐site transportation of waste. Off‐site transportation of waste is outsourced to a private firm. Incineration is used in the final disposal of infectious waste. Non‐infectious waste is disposed using land disposal method. There is no policy and plan in place for managing medical waste. A number of problems were identified with respect to medical waste management.

Originality/value

The paper gives recommendations with the aim of improving medical waste management in hospitals.

Abstract

Subject Area

Environment Management, Solid Waste Management.

Study Level

This case is suitable to be used in advanced undergraduate and MBA/MSc level.

Case Overview

This case revolves around the challenges pertaining to waste management in Iran. Poor waste management practices can result in soil contamination, water pollution, and air pollution, can cause respiratory problem, and can create permanent adverse health effect. Thus, a solid waste management system is needed for safeguarding the public health, safety, and welfare. However, it seems not an easy task for the developing countries, and Iran is not an exception to this. Recycling has three particular steps: collection and processing, manufacturing, and purchasing new products which made from recycled materials which require heavy investment. Lack of investment in the Iranian recycling sector has made this issue more complicated and lagging behind. This case highlights the challenges faced by the Iranian Municipality in this regard.

Expected Learning Outcomes

The learning objectives are as follows:

  • to expose students to an actual situation where they will be aware of the necessity to care for the environment and reduce and reuse the products that they are utilizing in their every days’ life;

  • to highlight the need of a municipal waste management system to make route optimization for waste collection and transport system, storage, recycling plan, compost and incineration facility, proper site for landfill, etc.; and

  • to emphasize the required support from all stake holders in managing waste.

Abstract

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

Abstract

Sustainable recycling activities in higher education institutions (HEIs) are crucial as it serves as a common benchmark to a community that is socially and environmentally responsible. This chapter presents a suitable case study of HEIs in Malaysia reporting on recycling rate, monitoring the recycling patterns, and matching the significant recycling policy in the HEIs. Therefore, four HEIs including Universiti Teknologi Malaysia (UTM), Universiti Malaya (UM), Universiti Kebangsaan Malaysia (UKM) and Universiti Putra Malaysia (UPM) were selected as the suitable case studies to examine the practices of recycling activities. These four HEIs are Malaysian research universities that are ranked in the top 300 in the UI Green Metric World University Rankings. Several findings and previous works were reviewed; further steps to set a recycling target were identified and served as a guidance of the standard recycling rate. Results showed the selected HEIs reflected the low percentage of recycling rate in the range of 0.03–29.26%, depending on its practices and policy. Three phases of planning have been structured to target the recycling rate at HEIs in Malaysia with the First Plan (2025), Second Plan (2035) and Third Plan (2040) towards the recycling rates of 20%, 30% and 40%, respectively. The recommendations for the HEIs formulate recycling policies and recycling rates, and for waste management, academia and research centres to play a more active role in increasing the efficiency of recycling activities for a positive impact on the recycling rate in HEIs.

Abstract

Purpose

The construction industry’s contribution to environmental deterioration is widely established in the literature, implying that addressing this issue will require a coordinated effort from all stakeholders. According to literature, stakeholder involvement without stakeholder management (SKM) is not enough, in ensuring efficient construction waste management (CWM). This study investigates the impact of SKM on efficient CWM by aggregating all relevant SKM variables and measuring their degree of influence on efficient CWM.

Design/methodology/approach

This study used a four-stage research approach that included a literature review, a pilot study, a questionnaire survey and statistical analysis. After a thorough examination of the literature, nine essential SKM factors were identified and tested by a questionnaire survey following a pilot study. A total of 310 questionnaires were filled out and returned for analysis (exploratory and confirmatory factor analysis).

Findings

The study established that SKM is a unidimensional construct since all the variables extracted unto one underlying component with total variance explained (TVE), accounting for 58.938% of the total Variance in the measure of SKM in efficient CWM. Additionally, the reliability and validity test results satisfied the recommended thresholds, thus justifying the factorability of the construct. Furthermore, the hypothesis test revealed that SKM has a statistically significant impact on efficient CWM, implying that increasing SKM will have a beneficial impact on efficient CWM.

Research limitations/implications

The study is limited to material waste management in the construction industry and the outcome was determined solely by a field survey in Ghana. Extending the study to other jurisdictions would have improved its findings and made them easier to generalise.

Practical implications

The study’s findings are helpful for practitioners and researchers, especially regarding the influence of the eight SKM variables on efficient CWM.

Social implications

The study’s findings will reduce pollution, thus enhancing public health and encouraging social inclusion through the creation of jobs in the waste management chain.

Originality/value

The uniqueness of this study is anchored on the fact that no CWM study has considered all the eight SKM variables measured in this study at the same time. Also, this study has contributed to the literature by establishing the determinants of SKM in efficient CWM in Ghana.

Abstract

Purpose

In less than a decade to sustainable development goals (SDGs) there is a threat of household waste emanating from sub-urban sprawl especially in developing countries. Private approaches with government-enabling environments have been proved a successful platform for urban services such as housing provision and telecommunication in developing cities. Still private solid waste management (PSWM) seems different in Nigeria. Therefore, this paper aims to investigate the possible perceived hindrances facing PSWM organisations and proffer feasible policies to enhance sustainable clean and healthy cities.

Design/methodology/approach

Seven communities within Benin City sub-urban environs were adopted as the study area to accomplish the research’s objectives via a phenomenology type of qualitative research design. The study analysed the collated data from the knowledgeable participants via a thematic approach.

Findings

Lax legislative, absence of institutional framework, inadequate economic motivation, inadequate technical operations, among others, emerged as the encumbrances faced by PSWM firms. Wastes dumped along unethical locations such as streets, roads, uncompleted buildings, culverts and drainage channels, and undeveloped plots emerged as the encumbrance outcomes. Findings show that proffering feasible policy solutions to tackle identified hindrances can promote the achievement of SDGs across semi-urban locations in Nigeria.

Research limitations/implications

This research is restricted to urban household waste management by PSWM within Nigeria. Also, the study identified the challenges and proffer policy solutions to enhance improved clean environment within the sub-urban and urban cities.

Practical implications

As part of this study’s implications, results from this research intend to guide government policymakers and PSWM firms to encourage collaboration in designing appropriate strategic and educational programmes for the householders (customers) in sub-cities. It will be achieved via feasible policies that are tailored towards achieving sustainable health and environment-friendly sub-urban locations.

Originality/value

This paper intends to enhance proper PSWM and create sustainable cities via collaboration. Also, the paper engaged key stakeholders via a qualitative research design to proffer possible solutions to the menace of sub-urban and urban household waste management.

Abstract

Purpose

This study aims to discuss to what extent are WMPs practical tools for circular and sustainable waste management in universities, presenting, therefore, a case study of the usage of WMP in the Brazilian public universities and comparing this scenario with the international context.

Design/methodology/approach

The WMPs were identified by online search and analyzed according to qualitative indicators (spatial-temporal distribution, year, extent and virtual availability), and through circularity and sustainability criteria, using a proposed checklist.

Findings

Even being mandatory instruments, only 17% of the 103 public universities in Brazil had a WMP identified, and, among these plans, 55% were restricted to healthcare services waste, only 15% covered all university campuses. Although most of the available plans indicate measures for more sustainable waste management (e.g., recyclable waste collection on campus), they lack specific deadlines for presented goals on waste management, treating waste management at a more emergency pace than in well-structured long-term planning.

Originality/value

Numerous studies have discussed waste management strategies for universities worldwide, but few have addressed the usage and structure of WMPs. A case study of the Brazilian situation in light of the international scenario is of great value in understanding the differences between universities in terms of waste management, and with strong potential to support the structuring of more solid environmental policies in universities, especially in developing countries.

Abstract

Purpose

The capacity of landfills will reach saturation in the 2020s. There are more than 50,000 buildings in Hong Kong over 30 years old and which may require extensive refurbishment under the Mandatory Building Scheme. Additionally, most new owners/tenants tend to renovate their premises before moving in. Hence, there is an urgent need in Hong Kong, to explore strategies and measures to enable the development of effective refurbishment and renovation (R&R) waste management for such projects. The objectives of this paper are to investigate the process of R&R for identifying the perceived barriers and thereby the strategies for minimisation and management of R&R waste in Hong Kong.

Design/methodology/approach

Desktop study, semi-structured interviews, site observations and document reviews were used as the data collection methods to achieve the objectives of this research. Considering the nature and characteristics of the industry structure, the snowball sampling process was deployed for data collection. Thematic analysis and content analysis were used for data analysis. Waste minimisation and management strategies for R&R projects were then discussed and developed by the research team and a focus group meeting was held to validate the research findings. Six strategies were then proposed to the government.

Findings

R&R projects contribute 10–20% of the construction and demolition waste. The barriers to recycling of R&R waste can be grouped into six major categories: (1) lack of sorting and storage spaces, (2) high cost, (3) insufficient government supporting policy, (4) complicated recycling processes, (5) immature recycling market and (6) insufficient public education. Also, six strategies are proposed in this study, which include (1) pre-refurbishment audit, (2) development of recycling market, (3) sea reclamation, (4) incineration, (5) government support and (6) education and research.

Originality/value

The strategies and measures proposed in this research could most adequately serve as reference for the government officials, building professionals and academic researchers. Such knowledge would make possible the development of effective strategies and measures for minimising and managing R&R waste.

Abstract

Purpose

In developed and developing countries, organizations need to do sustainability reporting. The purpose of this paper is to identify the vital linkages of sustainability, which helps to capture the existing waste management practice in sustainable organizations.

Design/methodology/approach

This paper reports a mixed-method approach for sustainable organization. Initially, the waste management and sustainability factors have been linked together for finding the relation between them through the situation, actor, process, learning, action, performance (SAP-LAP) linkages framework; it has been used as qualitative design details to achieve sustainability in the organization. The waste management and sustainability factors linkages have been used as a reference to guide the cause and effect relationship through decision-making trial and evaluation laboratory (DEMATEL) to upgrade knowledge for a sustainable organization.

Findings

The proposed method has been used to meet the functional requirements of sustainability in the organization. Waste management has been analyzed as the most significant benchmarks to achieve sustainability in the organization. The causal relationship reveals that the social image of an organization as a sustainable organization is the effect of its governmental directives, followed by the organization. The governmental directives is the most influencing dimension, and waste management efficiency and energy consumption are the most related, whereas wastivity is the most flexible dimension of sustainability in the organization. To increase its customer satisfaction, profit share and market value, these factors must be considered as vital factors of organization's sustainable performance.

Research limitations/implications

The scope of the present research has been limited to benchmark sustainability by analyzing eight waste management factors and ten critical sustainability factors that have been grouped into four dimensions in the service sector, which could be generalized. The expert's view has been captured for DEMATEL based on “ratings provided by experts,” which may be biased.

Practical implications

Benchmarked sustainability factors have been proposed to increase the value and performance of the organization. The cause and effect relationship is useful to present the capability of waste management to act as a strong foundation for establishing a sustainable organization, where governmental directives, wastivity, waste management efficiency, and energy consumption act as the benchmarking factors to compare sustainable organization performance in developing the county's viewpoint. The present study considered the fourth dimension of sustainability “government and customer” as the dynamic dimension of sustainability, which can absorb and diffuse the changes in sustainable organization with time and can improvise social acceptance.

Originality/value

The research improves the existing method of measuring the performance of the sustainable organization by using well-established methods.
