Abstract

The chapter illustrates the relationships between concepts, theories, and processes presented so far in the book.

The cases explored show how this model can be recognized first and foremost in publicly owned waste operators linked to the territory where the service is provided. The content that justifies and legitimizes their presence is that of the integral recovery of materials through the zero waste strategy.

Innovation, responsibility, stakeholder engagement, and knowledge sharing have been highlighted as the four key drivers of sustainable urban waste management. These drivers reciprocally reinforce each other in a virtuous exploitation system that generates a positive circular path of new managerial and technical resources and competencies, and new responsibility schemes shared among managers, policymakers, employees, and users.

Further, each key driver impacts the economic, environmental, and social performance of urban waste operators, increasing the overall impact and strengthening the effect of the other drivers in a virtuous exploitation of benefits for waste operators and stakeholders beyond the served territory.

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

Purpose

Reducing construction waste generation and carbon emission in the construction industry is crucial for the “dual carbon” goal. Evaluating the efficiency of reducing construction waste generation and carbon emission in the construction industry at the regional level is an important evaluation basis for the sustainable development of the construction industry. It provides a basis for formulating construction waste and carbon reduction policies tailored to local conditions and comprehensively promote the sustainable development of the construction industry.

Design/methodology/approach

A three stage SBM-DEA model based on non-expected outputs is proposed by combining the SBM-DEA model with the SFA method. The proposed model is used to evaluate the efficiency of construction waste and carbon reduction in the construction industry in 30 regions of China from 2010 to 2020. Moreover, the study explores the impact of environmental variables such as urbanization level, proportion of construction industry employees, resident consumption level, and technological progress.

Findings

From 2010 to 2020, the efficiency of construction waste and carbon reduction in China’s construction industry has been increasing year by year. Provinces with higher efficiency of construction waste and carbon reduction in the construction industry are mainly concentrated in the eastern coastal areas, showing an overall pattern of “East>West>Northeast>Middle”. There is a clear correlation between the level of urbanization, the proportion of construction industry employees, residents’ consumption level, technological progress, labor input, machinery input, and capital investment. The construction waste and carbon emission efficiency of the construction industry in various provinces is greatly influenced by environmental factors.

Practical implications

The research results provide policy makers and business managers with effective policies for reducing construction waste generation and carbon emission in the construction industry, especially circular economy policies. To provide empirical support for further understanding the connotation of construction waste and carbon reduction in the construction industry, to create innovative models for construction waste and carbon reduction, and to promote the multiple benefits of construction waste and carbon reduction in the construction industry, and to provide empirical support for countries and enterprises with similar development backgrounds in China to formulate relevant policies and decision-making.

Originality/value

The construction industry is a high investment, high energy consumption, and high pollution industry. This study uses the three stage SBM-DEA model to explore the efficiency of construction waste and carbon reduction in the construction industry, providing a new perspective for the evaluation of sustainable development in the construction industry, enriching and improving the theory of sustainable development.

Abstract

Purpose

Wool fiber is accepted as one of the natural and renewable sources and has been used in the apparel and textile industry since ancient times. However, wool fiber has the highest global warming potential value among conventional fibres due to its high land use and high methane gas generation. This study aimed to recycle the wool fabric wastes and also to create a mini eco-collection by using the produced yarns.

Design/methodology/approach

This manuscript aimed to evaluate the fabric wastes of a woolen fabric producer company. Fabric wastes were opened with two different opening systems and fiber properties were determined. First, conventional ring yarns were produced in the company’s own spinning mill by mixing the opened fibres with the long fiber wastes of the company. In addition, opening wastes were mixed with different fibres (polyester, long wool waste, and Tencel fibres) between 25% and 70% in the short-staple yarn spinning mill and used in the production of conventional ring and OE-rotor yarns. Most of the yarns contained waste fibres at 50%. Recycled and virgin yarns were used as a weft and warp yarn and a total of 270 woven fabric samples were obtained and fabric properties were examined. Also, a fabric collection was created. A life cycle assessment (LCA) was made for one of the selected yarns.

Findings

At the end of the study, it was determined that it was possible to produce yarn and fabric samples from fiber blends containing high waste fiber ratios beyond 50%. All the woven fabric samples produced from conventional ring and OE-rotor yarns gave higher breaking, tearing and stitch slip strength values in the weft and warp direction than limit quality values of the company. In addition, abrasion resistance and WIRA steam stability properties of the fabric samples were also sufficient. Environmental analysis of the recycling of the wastes showed a possible decrease of about 9940034.3 kg CO2e per year in the global warming potential. In addition, fiber raw material expenses reduced yarn production cost about 50% in case of opened fabric waste usage. However, due to insufficient pilling resistance results, it was decided to evaluate the woven fabrics for the product groups such as shawls and blankets, where pilling resistance is less sought.

Originality/value

The original aspects of the article can be summarized under two headings. First, there are limited studies on the evaluation of wool wastes compared to cotton and polyester fibres and the number of samples examined was limited. However, this study was quite comprehensive in terms of opening type (rag and tearing), spinning systems (long and short spinning processes), fiber blends (waste 100% and blends with polyester, long wool waste and Tencel fibres) and yarn counts (coarser and finer). Recycled and virgin yarns were used as a weft and warp yarn and a total of 270 woven fabric samples were obtained using different colour combinations and weave types. All processes from fabric waste to product production were followed and evaluated. Life cycle assessment (LCA) and cost analysis was also done. The second unique aspect is that the problem of a real wool company was handled by taking the waste of the woolen company and a collection was created for the customer group of the company. Production was made under real production conditions. Therefore, this study will provide important findings to the research field about recycling, sustainability etc.

Abstract

Purpose

The paper focusses on various ways of global circular economies’ resource optimisation. The paper examines corporations’ corporate social responsibility (CSR) initiatives in bringing circularity. This paper identifies research gaps in waste management in linear economies such as India. It concludes with a proposition for waste management advocating the ADKAR model framework of change.

Design/methodology/approach

This paper reviews the academic repositories and reports to find answers to the circularity gaps. Databases such as Emerald, Web of Science and Springer were used to construct the theory. The author used keywords such as “circular economy”, “circular economy and SDG”, “circular economy and CSR”, and “circular economy and waste management” to locate the relevant literature to build the theory. Based on the theory, the waste management gap is identified and analysed.

Findings

The paper collates and examines the interdependency factors promoting circularity. An analysis of exemplary circular economies and corporations gives a pathway for linear economies. Finally, a framework is formulated for India’s transition from a linear to a circular economy using the best practices of different circular economies’ waste minimisation techniques. It summarises the findings of circular economies, formulating an ADKAR framework for waste management to aid circularity in India.

Research limitations/implications

This research must be validated with the practical implications of an economy’s ecosystem. The economies’ binding policies and statutory regulations must be gauged through valid metrics for each circular economy, ultimately determining its efficacy in transitioning from linear to circular economy.

Practical implications

The circularity in production and responsible consumption by all the stakeholders leads to sustainability. Embracing new sustainable practices, CSR initiatives will lead to circularity at the nano, micro, meso and macro levels for a populous economy such as India. The ADKAR model proposed can bring a positive change in India.

Social implications

The United Nations’ sustainability goal 12 (Responsible consumption and production) focusses on resource optimisation. This paper proposes ways to involve stakeholders to minimise waste at the source through a multi-level approach.

Originality/value

This paper attempts to assess an economy’s sustainability by analysing its circularity gaps and highlighting the best practices of circular economies. It also outlines the framework for circularity through waste reduction and minimisation using the ADKAR model.

Abstract

Purpose

An efficient e-waste management system is developed, aided by deep learning techniques. Here, a smart bin system using Internet of things (IoT) sensors is generated. The sensors detect the level of waste in the dustbin. The data collected by the IoT sensor is stored in the blockchain. Here, an adaptive deep Markov random field (ADMRF) method is implemented to determine the weight of the wastes. The performance of the ADMRF is boosted by optimizing its parameters with the help of the improved corona virus herd immunity optimization algorithm (ICVHIOA). Here, the main objective of the developed ADMRF-based waste weight prediction is to minimize the root mean square error (RMSE) and mean absolute error (MAE) rate at the time of testing. If the weight of the bins is more than 80%, then an alert message will be sent to the waste collector directly. Optimal route selection is carried out using the developed ICVHIOA for efficient collection of wastes from the smart bin. Here, the main objectives of the optimal route selection are to reduce the distance and time to minimize the operational cost and the environmental impacts. The collected waste is then considered for recycling. The performance of the implemented IoT and blockchain-based smart dustbin is evaluated by comparing it with other existing smart dustbins for e-waste management.

Design/methodology/approach

The developed e-waste management system is used to collect the waste and to avoid certain diseases caused by the dumped waste. Disposal and recycling of the e-waste is necessary to decrease pollution and to manufacture new products from the waste.

Findings

The RMSE of the implemented framework was 33.65% better than convolutional neural network (CNN), 27.12% increased than recurrent neural network (RNN), 22.27% advanced than Resnet and 9.99% superior to long short-term memory (LSTM).

Originality/value

The proposed E-waste management system has given an enhanced performance rate in weight prediction and also in optimal route selection when compared with other conventional methods.

Abstract

Purpose

This study aims to provide insights into the drivers of student engagement in food waste reduction strategies in educational institutions. The proposed research model integrates social media celebrities' attractiveness, expertise and trustworthiness with the value belief norm (VBN) theory to explore their influence on students' behaviour towards food waste reduction.

Design/methodology/approach

The data were collected from 417 students enrolled in public and private universities in the Riyadh and Macca regions of Saudi Arabia to evaluate the proposed model. The partial least squares-structural equation modelling (PLS-SEM) was employed to analyse the responses.

Findings

The results showed that VBN theory's components, such as values (biospheric, altruistic and egoistic), beliefs (new ecological paradigm, awareness of consequences and aspirations of responsibility) and norms significantly and positively influence food waste reduction behavioural intentions. It was also discovered from the results that social media celebrities' attractiveness, expertise and trustworthiness influence food waste reduction behavioural intentions.

Originality/value

This study contributes significantly to the literature by identifying factors influencing student engagement in food waste reduction strategies in educational institutions where limited research exists. It fills this research gap by developing a novel theoretical framework integrating social media celebrities' attributes with the VBN theory to explain these factors.

Abstract

Purpose

The purpose of this short communication is to shed light on the accuracy of quantification methods of household food waste (HFW).

Design/methodology/approach

Thirty-seven recently published studies in HFW were surveyed for this commentary. Exemplary methods and findings of these studies were compared.

Findings

It is challenging to draw conclusions on the amount of the HFW per person/town/country due to the inconsistent and heterogeneous methodologies used. We recommend using direct measurements or triangulation of methods to help ensure valid findings. Governments should incentivize consumers to deliver their food waste to designated locations where weights could accurately be assessed. Monetary or tax incentives could help stimulate an accurate accounting of waste and encourage reductions. Food waste measurements should be consistently reported as kg/person/week.

Social implications

Food and water security must be provided for all. It is estimated that one-third of edible food for humans is currently lost or wasted globally. According to the World Food Program (WFP), this is about 1.3 billion tons of food per year and at the same time this wasted food could be sufficient to feed two billion people.

Originality/value

The aim of this paper is to fill a gap in the literature about the magnitude and significance of HFW and its impact on the environment and social welfare. Currently, there are no generally accepted uniform methods of food waste quantification at the household level. This original communication brings the importance and challenges of the quantification of HFW to light.
