This research investigates factors affecting the intention to sort waste. Specifically, this research aims to develop a waste-sorting intention model by extending the theory of planned behavior (TPB) model and to test the model to ensure the model's goodness-of-fit, validity and reliability.

This research used a quantitative research methodology. Data were collected from 460 respondents using an online questionnaire. Some statistical analyses were performed to analyze the data: descriptive statistics, factor analysis, confirmatory factor analysis-structural equation modeling (CFA-SEM), SEM and Cronbach's alpha analysis.

The result shows that the intention to sort waste was directly affected by attitude, subjective norms, perceived behavioral control (PBC), moral obligation and facility support. Environmental concerns, waste-sorting knowledge and time availability indirectly influenced the intention to sort waste. The testing indicated that the proposed model was fit, valid and reliable.

The model provides a more comprehensive understanding of waste-sorting intention. The central and local governments can use the results to encourage waste-sorting intention in the community.

This research is believed to be the first study to develop and test the waste-sorting intention model that extends the TPB model by incorporating moral obligation, facility support, policy and regulation support, environmental concerns, waste-sorting knowledge and time availability into the traditional TPB model.

The research objectives are as follows: to understand the situation of solid waste management in the Makham Tia Subdistrict Administrative Organization, Surat Thani Province, Thailand; identify the patterns in household waste generation and 3Rs behavior (recycle, reuse and reduce waste); and formulate sustainable municipal solid waste management guidelines.

This study aimed to propose the solution by using data analysis and a participatory research approach to set the guidelines for sustainable community waste management in a low-budget area. A survey of household behavior was done with questionnaires. Mixed clustering using the Gower coefficient was performed to assess the categorical socio-demographic variables along with the numeric variables related to the 3Rs behavior. The guidelines for waste management were generated based on the characteristics of the household groups.

The guidelines for waste management were generated based on the characteristics of the household groups. An appropriate practical plan for municipal solid waste management in Makham Tia Subdistrict was proposed in this work. The study showed that the guidelines were implemented and revised by members of the community, and this led to the development of sustainable community solid waste management for the future.

The goal of this study was to provide a solution for sustainable community waste management in a low-budget location by using data mining techniques and a participatory research approach. The study showed that the guidelines were implemented and revised by members of the community, and this led to the development of sustainable community solid waste management for the future.

With rapid industrialization and urbanization, municipal solid waste (MSW) management has become a serious challenge worldwide, especially in developing countries. The Beijing Municipality is a representative example of many local governments in China that are facing MSW management issues. Although there have been studies in the area of MSW management in the literature, less attention has been devoted to developing a structured framework that identifies and interprets the barriers to MSW management in megacities, especially in Beijing. Therefore, this study focuses on identifying a comprehensive list of barriers affecting the successful implementation of MSW management in Beijing.

Through an extensive review of related literature, 12 barriers are identified and classified into five categories: government, waste, knowledge dissemination, MSW management process and market. Using an integrated approach including the decision-making trial and evaluation laboratory (DEMATEL), maximum mean de-entropy algorithm (MMDE) and interpretive structural modeling (ISM), a conceptual structural model of MSW implementation barriers is constructed to provide insights for industrial decision-makers and policymakers.

The results show that a lack of economic support from the government, imperfect MSW-related laws and regulations, the low education of residents and the lack of publicity of waste recycling knowledge are the main barriers to MSW management in Beijing. Combined with expert opinions, the paper provides suggestions and guidance to municipal authorities and industry practitioners to guide the successful implementation of MSW management.

The findings of this study can provide a reference for MSW management in other metropolises in China and other developing countries.

This study proposes a hybrid DEMATEL-MMDE-ISM approach to resolve the subjectivity issues of the traditional ISM approach and it analyzes the barriers that hinder MSW management practices in Beijing.

To examine and create an ideal pathway model that can implement aiming to change the current improper practices in managing municipal solid waste (MSW) to sustainable practices. To acquire a better understanding of public participation and community culture helps in achieving the aim of reducing the amount of waste generation, sending less waste to landfill sites and encouraging the reuse and recycling of materials instead. To help students whom the awareness in the community regarding the importance of protecting the environment and acting in a civilization way has increased. To improve the MSW sustainability practices and enhance the waste sustainability practices together with energy and material conservation. To have more extensive knowledge and awareness of issues in waste management and some of the dilemmas managers of strategic and operations face.

Abu Dhabi’s center of waste management is known as Tadweer is a governmental entity under the Abu Dhabi Executive Council. Tadweer is responsible for managing every MSWs includes collecting, transferring, segregating, treating, recycling, reusing and tracking all kinds of wastes. CEO of Tadweer Dr Salem Alkabi called his team that manages various departments such as strategy, operations, projects and licensing. The meeting was to discuss Tadweer’s future directing and strategy for mismanagement of solid waste dumping into landfills in Abu Dhabi. Dumping in landfills is the main challenge Tadweer faced. Mr. Abdulrahman Albloushi’s strategy and business development executive director of Tadweer highlighted to Alkaabi how Tadweer could improve the waste management practices to make it more sustainable. Furthermore, assisting the center gets more benefit from the waste s instead of losing this valuable waste into landfills. Consequently, Mr. Abdulrahman must grapple with some difficult questions: how much the effectiveness in collecting waste from where it generated and removing it out-of-sight?

This case study is designed for undergraduate and postgraduate students, and executive MBA students of business management programs, especially for waste management, environmental management and strategic management courses.

A sustainability audit of Holme Lacy College is described. The approach adopted a “triple bottom line” assessment, comprising a number of key steps: a scoping review utilising a revised Royal Institution of Chartered Surveyors project appraisal tool; an environmental impact assessment based on ecological footprinting and a social and economic impact assessment. The college has a number of unsustainable features. Its ecological footprint is equivalent to 296 ha and some 866 tonnes of CO₂ were emitted from the site over a one‐year period. The social impact of the college and its staff is significant over a wide range of stakeholders and the region. The economic impact indicates that the college contributes up to £5.3 million to the local and regional economy.

The purpose of this paper is to explore informational structures producing and organising the construction of waste sorting in Sweden. It shows how the issue is constructed by it being searched for in Google and how this contributes to the specific informational texture of waste sorting in Sweden. It is guided by the following questions: who are the main actors and which are the central topics featuring in Google results on popular, suggested searches for waste sorting in Sweden? What do the link relations between these tell the author about the issue space that is formed around waste sorting in Sweden? How is the construction of the notions of waste sorting and waste shaped in the information available through Google’s features for related and other relevant searches?

Waste sorting is discussed as a practice structured along moral rules and as a classification exercise. The study brings together two types of material, results from searches carried out in Google and lists of Google query suggestions for relevant search terms. These are analysed with a mixed method approach, uniting quantitative network analysis and qualitative content analysis of query suggestions. A sociomaterial approach theoretically grounds the analysis.

Waste sorting in Sweden emerges as an issue that is characterised by dense networks of rules and regulation, focused in public authorities and government agencies, which in turn address consumers, waste management businesses and other authorities. Search engine use and waste sorting in Sweden are shown to be joined together in various mundane everyday life practices and practices of governance that become visible through the search engine in form of search results and suggested searches. The search engine is shown to work as a fluid classification system, which is also created and shaped by its use.

The study offers a novel methodological approach to studying the informational structures of an issue and of its shaping through it being searched for. The sociomaterially grounded analysis of Google as a fluid classification system is original.

This study aims to examine the role of personal and subjective norms in predicting waste sorting, an increasingly relevant pro-environmental behavior.

This study obtained data from a sample of 300 respondents from three Indonesian cities. Purposive sampling was employed to obtain information from specific segments of Indonesian population. The analysis consisted of a two-stage procedure including confirmatory factor analysis and covariance-based structural equation modeling.

Results demonstrated that both subjective and personal norms significantly and directly predict waste sorting behavior (WSB) bypassing intention to behave.

The fact that norms held by individuals are able to single-handedly drive pro-environmental behaviors implies that previous studies and social marketing campaigns may have overstated the role of intention.

In designing marketing communication programs promoting WSB, this paper argues that targeting normative tendencies of the audience may provide a more effective strategy than focusing on explicit pro-environmental intentions and attitudes of the public.

This study provided a new experimental test and confirmation of the role of subjective norms, the normative component of the theory of planned behavior and of personal norms, the normative component of the norm activation theory, in predicting WSB.

The purpose of this paper is to assess the reliability of questionnaires as a method of quantifying household food waste (FW), thus providing context regarding the validity of existing Italian estimates.

A total of 30 households were involved in a diary study that was conducted for one week. The participating households were first asked about their FW quantities in a questionnaire. Half of the households who filled their diaries properly were then audited through waste sorting analysis performed on their garbage. Non-parametric tests were used to test for differences in FW estimates between audited and non-audited households, as well as differences among estimates obtained through different quantification methodologies.

Edible FW was estimated to be 489 grams per week based on questionnaires, and 1,035 grams per week based on diaries. In the audited sub-sample of households, FW estimates were 334 grams per week based on questionnaires, 818 grams per week based on diaries and 1,058 grams per week based on waste sorting analysis.

Given the small sample size in the present study, future studies can utilize larger samples to assess whether the differences identified in estimates can be replicated. Future studies can also inquire into the behavioral biases that led consumers to underestimate their FW.

Results of the present study point against the use of questionnaires to quantify household FW, hence raising some doubt on the reliability of existent Italian estimates. Where waste sorting is unfeasible, the use of adjustment methods or diaries is suggested to better inform policies.

This study is one of the first on FW quantification that tests three different methodologies on the same sample, and is the first to do so in Italy, where estimates are still very poor.

The paper aims to ascertain whether residents in Nguyen Du ward still sort their waste at source following the end of the 3R project that ended in 2009. Additionally, this paper aims to explore the relationship between waste separation practices and social bonds.

The Travis Hirschi theory of social control was applied, together with the mixed method research design which included a structured questionnaire survey. Twelve semi-structured interviews were also conducted with residents and the data processed by SPSS software, using Chi-Square test, Independent-Samples t-test and Pearson's correlation analysis.

A proportion of respondents has continued practicing waste separation since the 3R project ended. The study also indicated that the greater the involvement in family and neighborhood activities the more the participants were likely to practice waste separation.

The small sample size limits the extent to which the most influential factors can be determined and therefore the degree to which the findings can be generalized.

The study includes implications for rerunning the waste separation programs for households as together with community campaigns to improve individuals' attachment and commitment and thus their participation in pro-environmental behaviors.

To the author’s knowledge, this is the first study to take a sociological approach to investigate factors affecting household waste separation, which has attracted little attention in previous studies. Useful information is also provided to local authorities for a policy-making process to implement effective domestic waste policies.

This paper aims to analyse the factors influencing refurbishment site managers’ waste management efforts.

Twenty-seven semi-structured interviews were held with managers from two large contractors involved in housing and office refurbishment projects in Sweden. Also, a web and postal questionnaire survey was sent to 232 refurbishment site managers and received a 34 per cent response rate.

Site managers devise waste management strategies based on environmental inventories and project size. In smaller projects, waste contractors are employed only for physical activities rather than providing advice. Site managers’ waste management efforts are influenced by project-related factors, organizational and personal factors, technical factors, industry culture and legislation. The level of contract detail, specific client demands related to waste management and project size are important factors.

Policies and guidelines for projects of different sizes should be developed at least for large contractors; scale influences site managers’ waste strategies. Waste management efforts in refurbishment projects can be improved by addressing simple technical problems including providing clear labelling of containers and ensuring shelter from rain and snow.

This is a pioneer survey of refurbishment site manager opinions and practices. Inefficient waste management in building refurbishment projects can be costly and harmful to the environment. There are many opportunities to improve waste management efforts.
