Community-Level Household Waste Disposal Behavior Simulation and Visualization under Multiple Incentive Policies—An Agent-Based Modelling Approach

The classification and recycling of household waste becomes a major issue in today’s urban environmental protection and domestic waste disposal. Although various policies promoting household waste classification have been introduced, the recovery rate failed to reach the expected result. Existing studies on incentive policies for household waste recycling tried to integrate subjective and objective factors in human behavior decisions. To explore how effective interventions can promote household waste classification in communities, this article developed an Agent-Based Model (ABM) based on Theory of Planned Behavior (TPB) to simulate the participation of households under eight different policy scenarios. The result shows that: monetary incentive is most effective in inducing participation, while social norms have different impacts on household decision under different policy intervention. Under policy stimulus, the participation rate of garbage sorting increased from 18% to 76%. This model has been applied into an online community-based participatory virtual simulation 3D system, which aims to help university students better understand how policies affect household recycling behaviors, which end up affecting the environment.

The imperative of communication signals in boosting business strategies of the bioplastic packaging industry

AbstractDespite the rapid growth of sustainable innovations in bioplastics for packaging industries, their diffusion into established markets has so far been hampered by ambiguous and asymmetrical communication between bioplastics producers and consumers (both businesses and end consumers), particularly related to bioplastics materials and their waste disposal procedures. This study looks into the communication processes, identifies barriers and investigates business strategies that can be adopted by bioplastic packaging industries to influence consumer adoption and proper disposal behaviour of bioplastic packaging. Based on a systematic review of 68 journal articles and guided by the signalling theory, the study found that connections with various signallers at the end‐of‐life of bioplastic packaging materials are required beyond the purview of the industrial sectors utilising the packaging. The paper proposes a conceptual framework incorporating new signal constructs specific to consumer‐facing sustainable innovation. The framework extends the signalling theory to be used as part of the bioplastic packaging industry's business strategy. The paper also emphasises the importance of altering the communication mechanisms in order to boost bioplastics industrial practices, which will subsequently contribute to the reduction of the detrimental impacts of fossil‐based plastics on the environment.

The role of behavior accessibility and individual risk perceptions in chronic wasting disease risk mitigation behaviors among Minnesota deer hunters

ABSTRACT Human activities, including the movement of harvested cervids, pose significant risks for spreading chronic wasting disease (CWD) to new locations. This study used hierarchical agglomerative clustering to compare Minnesota, USA hunters’ carcass disposal habits and likelihood of CWD testing as a function of individual differences in risk perceptions and hunting area. We utilized a survey of Minnesota hunters conducted during Spring 2020 that included a random sample of individuals that hunt statewide and in a local disease management zone (N = 5,000, response rate = 33%). We did not detect a significant difference in disposal behaviors as a function of CWD risk perceptions, but rather because of increased accessibility of low-risk disposal methods. Conversely, we found perceived likelihood of conducting CWD testing was positively associated with perceptions of risk. These findings have implications for vector tracing for future CWD outbreaks and highlight the benefit of understanding constituent habits and regulation compliance in disease management.

Exploring the factors influencing consumer behaviours and practices towards sustainable WEEE management in Putrajaya, Malaysia

The disposal practises and preferences of household waste from electrical and electronic equipment disposal (WEEE) are essential components in material flow analysis (MFA). Nevertheless, the synergistic of consumers’ behaviours and preferences with the disposal of different WEEE has yet to be investigated in depth. This study examined several consumer features of WEEE management using a quantitative questionnaire survey, including consumers' disposal behaviours and preferences. As a Malaysian federal government administrative centre, and model of a contemporary and sustainable Malaysian city, Putrajaya was chosen as the study area. Using stratified random sampling, the questionnaire was distributed through face-to-face and online surveys among households across 20 precincts within Putrajaya. From June 2021 to January 2022, 500 surveys were distributed over seven months, and IBM SPSS Statistic version 26 was used to analyse the data. The result shows that 80% of respondents have a good knowledge of WEEE management and are fully aware of the dangerous materials they have in their WEEE. 75% said they would recycle their WEEE, but only 44% said they would separate it from other household wastes. It was also shown that 88% of the household were willing to pay a collection fee of at least RM 10 for each collection. This analysis found that Extended Producer Responsibility (EPR) mechanisms can assist in overcoming weaknesses in WEEE management by including beneficial schemes to incentivise consumers to improve current waste policies. In the meantime, governments, media, and local non-governmental organisations may help by increasing awareness of effective and sustainable WEEE management.

University students' awareness of e-waste and its disposal practices in Pakistan: a construction of the conceptual framework.

Pakistan is among the few countries generating and receiving enormous e-waste, which posits a threat to itsfuture generations. A systematic literature review also suggests exploring e-waste awareness in Asia to understand awareness and behavior. Therefore, the present study explored university students' awareness of e-waste and the factors hindering the disposal of laptops, personal computers, and cellphones and suggested a conceptual framework. The study used the qualitative research approach and non-probability sampling. We collected data through four focus group discussions (FGDs) with students at a Pakistani university. After data saturation, we developed themes from FGDs and found computer sciences and engineering students with better awareness than others. The factors hindering e-waste disposal were lower monetary benefits for disposal, breach of sensitive information, nostalgic association with devices, and non-availability of disposal facilities. Other variables like lower resale value and high family sharing increased the storage of e-devices and reduced e-waste disposal. The research is among a few initial attempts to explore e-waste awareness and factors hindering disposal behavior in e-waste-receiving countries (e.g., Pakistan) and provides evidence from students who are the primary users. Our findings are crucial for policymakers to take corrective actions, introduce monetary benefits, and secure disposal to reduce e-waste.

Female Consumers’ Involvement in Intentional Non-Sustainable and Unintentional Sustainable Apparel Decisions: An Emerging Market Perspective

This study is aimed at determining consumers’ sustainable apparel involvement in the purchasing or disposing of apparel in an emerging market context (EMC). Consumers in developed countries show increased interest in sustainable apparel behaviour, contrary to emerging markets such as South Africa, which is indicative of the lowest level of sustainable apparel consumption. An exploratory descriptive qualitative research design was used to determine consumers’ involvement and was facilitated through eleven digitally recorded small focus groups with female apparel shoppers who make use of a custom-made apparel designers. The findings reveal intentional non-sustainable apparel decisions manifest through eco-uninvolved in- store purchases and once-off commissioned designer apparel orders. Unintentional sustainable apparel behaviour is characterised by (1) in-store apparel purchases: signifying quality clothing, observed in the material and stitching, resulting in clothing items worn for longer and handed down from generation to generation, sensitivity to the origin of the garment and (2) apparel disposal behaviour such as (a) keeping apparel as cleaning material and repurposing into wearable apparel; (b) permanent disposal through handing down items and (c) temporary disposal through exchanged items. Applying the Elaboration Likelihood Model, it was possible to explain the lack of elaborated involvement in sustainable apparel practices resembling the peripheral route of the model. Unintentional sustainable practices have not been identified in the South African context, indicating the valuable contribution consumers in an emerging market context (EMC) can make if better awareness is created by the government and the retail sector specifically to address intentional non-sustainable purchasing behaviours in future.

Think before you throw! An analysis of behavioral interventions targeting PET bottle recycling in the United States

The United States generates 42 Mt of plastic waste each year and is one of the biggest contributors to ocean plastic waste. Consequently, plastic has become synonymous with the linear economy, and many scholars are studying and proposing circular economy solutions to mitigate plastic pollution. Recycling has received much attention from both social sciences and engineering as a circular economy strategy, but no study has yet quantified how behavioral interventions could asymmetrically affect different populations. This study combines agent-based modeling, material flow analysis, system dynamics, and life cycle assessment to assess the effect of four behavioral interventions on the collection rates of polyethylene terephthalate bottle waste, displaced virgin plastic manufacturing, and avoided greenhouse gas (GHG) emissions. Results show that, while behavioral interventions would require about 300–900 GJ of additional energy at end-of-life due to improved collection rates, they would avoid about 500–700 thousand metric tons of GHG emissions. Results also illustrate the importance of habits in disposal behaviors and show that different forms of interventions can be better adapted to particular social contexts than others. While the circular economy and its application to plastic waste should certainly not be restricted to recycling, this study demonstrates that improved collection rates and recycling technologies can contribute to reducing the amount of plastic waste polluting our oceans.

Plastic Use Among Sri Lanka's Metropolitan Population: A Study of Environmental Consciousness and Behaviour

This study seeks to evaluate customers' purchase and disposal patterns for plastic and polythene and whether their environmental consciousness matches with actual behaviour. Data were collected from 117 households in metropolitan areas in Sri Lanka and analysed using descriptive statistics and paired sample t-test. Before data analysis, the scales' reliability and validity were evaluated. Findings showed a significant gap between actual behaviour concerning plastic consumption and environmental consciousness. Although most customers have positive opinions regarding environmental awareness, these beliefs have not necessarily converted into the corresponding behaviour to the same degree. As per results, 39% of the respondents burn their waste, including plastics, in open, while 4% have engaged in open dumping. The findings of this study can be taken into consideration to minimize the harmful effects of plastic and polythene disposal behaviour in Sri Lanka through an understanding of consumers’ actual behaviours. Especially relevant authorities shall initiate awareness campaigns and proper garbage disposal systems.

Identifying the determinants of face mask disposal behavior and policy implications: An application of the extended theory of planned behavior

A study in Nigeria examined the psychological factors affecting face mask disposal behavior (DB) during the COVID-19 pandemic. The Theory of Planned Behavior (TPB) was used, with awareness of consequences and institutional barriers added. 1183 respondents completed an online survey, and structural equation modeling was used to analyze the data. The original TPB model revealed that attitudes, perceived behavioral control, and subjective norms explained 65% of the variance in respondents' behavior. Behavioral intention and perceived behavioral control accounted for 59.3% of the variance in DB. The extended TPB model, which included awareness of consequences and perceived institutional barriers, improved the model's explanatory power by 12.8%. Both TPB models adequately predicted face mask (FM) disposal behavior, with implications for policymakers and waste management authorities to design interventions to promote proper FM disposal behavior.

The veterinarian's role in and attitude to the disposal of unwanted pharmaceuticals

A wide range of pharmaceutical chemicals have been documented in rivers, streams, lakes, coastal waters, groundwater, sewage sludge, landfill leachate, soils, air, and plant and animal tissues nationwide and around the world. Veterinarians’ unique relationship with pharmaceuticals compared to other health professionals provide a wide breath of potential pathways. Given the role that veterinarians can play as both a source of new pharmaceuticals to the environment and a method of drug disposal, as well as their role as trusted professionals, the veterinarian is key to keeping unused and unwanted medicine out of the environment. However, little is known about their behaviors. The objectives were to: learn about the drug disposal practices of the veterinarian and their clients from the veterinarian's perspective; learn about the importance of the topic of drug disposal to veterinarians; and determine the outreach needs and preferences of veterinarians and how best to educate about this issue. This research was conducted through a cross-sectional online survey of licensed veterinarians in states within the Great Lakes region working with those states’ veterinary medical associations or licensing boards. The 587 respondents were 72% female, 81% small animal practice, and 52% practicing in suburban geographic areas. Legal disposal requirements were the biggest factor influencing veterinarians to change pharmaceutical disposal behaviors followed by avoiding misuse and abuse. Veterinarians discussed disposal with clients in only 11% of appointments with clients. The most notable barriers include not remembering to mention, not enough time, not high enough priority, or not enough information known by the veterinarian. Continuing education opportunities need to be provided across the spectrum of practicing veterinarians so they can have a greater understanding of the problem of pharmaceutical waste and potential avenues they can implement to mitigate.

Perceived values to personal digital archives and their relationship to archiving behaviours: An exploratory research based on grounded theory

Personal digital archiving (PDA) is a type of personal information behaviour related to personal memory and identity construction. The aim of this study is to discover and define individual’s perceived values in relation to personal digital archives, and to explore their relationship between PDA behaviours. Based on the grounded theory, drawing on in-depth interviews with 14 Chinese college students, both the perceived values in relation to personal digital archives and the PDA behaviours were coded through open, axial, and selective coding processes. This study found the perceived values in relation to personal digital archives mainly include subject value, object value, intermediary value, value to other subjects and social value, PDA behaviours mainly include accumulation behaviour, use behaviour, appraisal behaviour and disposal behaviour. Moreover, the value cognition of personal digital archives is the intermediary link between perceived values and PDA behaviours and is the core connecting the two. Value cognition can be divided into judgement on whether personal digital archives are valuable, subdivision of value types of personal digital archives, value evaluation of personal digital archives, and cognition of enhancing or weakening the value of personal digital archives. The study comprehensively analysed the perceived values, value cognition that drive PDA behaviours, built the relationship between perceived values, value cognition and PDA behaviours, and answered the question of why individuals want to archive from cognitive and behavioural perspectives. The findings of the study can help librarians to conduct more targetted PDA education and improve the public’s awareness and literacy in PDA.

Does Food Shopping Behaviour Determine Food Waste Vulnerability in Private Households? Quantitative Analysis on Case Studies from Germany

The discussion about food waste is conducted from many different scientific perspectives. Studies from the perspective of retail geography have hardly been part of this so far. Within the framework of own empirical studies 2020–2022 for case studies from Germany, postal and online surveys were conducted in urban and rural areas in order to correlate psychographic attitudes according to self-assessment about food and shopping with practical shopping and disposal behaviour. Four different clusters can be distinguished, demonstrating that food waste realities are associated with characteristic attitude sets of groups of people as either unconscious wasters or conscious savers. Waste baskets are visualised via relational networks, which help to capture the complexity and completeness of sources of food waste in private households. This approach makes it possible to expand the causes of food waste not only in private households themselves, but also from upstream purchasing practices and the retail geographical characteristics of individual business formats. This study shows that the differences between groups and their receptiveness to the issue of food waste do not diverge systematically, but that niche-like variations in attitudes or purchasing behaviour can make a big difference.

Determinants of household waste disposal practices and implications for practical community interventions: lessons from Lilongwe

Open waste disposal has a negative effect on local ecology, economy, and public health. Understanding factors influencing waste disposal decisions is necessary for developing solutions to curb open waste disposal. This paper discusses the associations between household’s social demographic and spatial characteristics with preference for domestic waste disposal. The paper also utilizes this knowledge practical community action. This was achieved by gathering and examining a novel dataset of the waste disposal patterns of 200 randomly chosen households in Malawi. We observed that households were likely to dispose of their waste openly when the residential unit was closer to an existing open waste disposal site. A multinomial logistic regression model showed that the likelihood of choosing waste disposal methods, such as private garbage collection services, is higher when the household head is a woman, the housing unit is owned by the occupants, or in situations where a fence is present around the housing unit. We presented these findings to the neighborhood community development committee. A short-term community waste management plan was created using a participatory community planning approach. The plan included co-designing waste disposal solutions with landlords, setting up community waste bylaws, and intensifying civic education activities. In conclusion, our study provides insights into the factors that influence households’ disposal behavior. This unique case study highlights a potential approach for developing waste management policies using a bottom-up approach.

Pharmaceutical waste disposal practices: a case study of an Australian public hospital pharmacy department

AbstractBackgroundIn Queensland, each hospital and health service (local hospital network) has its own waste reduction and recycling plan to comply with the Queensland Government's Waste Reduction and Recycling Act 2011 (Qld). The aim is to reduce both the hospital's carbon footprint and waste handling costs. Hospital environmental waste services staff do not audit pharmaceutical waste bins as this requires the presence of a registered pharmacist.AimSince previous published studies of healthcare waste disposal practices have not included pharmacy waste bin audits, this study aimed to investigate waste disposal behaviours in a hospital pharmacy department.MethodThis sequential, two‐phase mixed methods study was conducted in a metropolitan, tertiary public hospital's pharmacy department in Queensland. Phase I involved semi‐structured interviews of hospital pharmacists and pharmacy technicians while Phase II comprised bin audits of the pharmacy department's waste streams.ResultsThe bin audits revealed 36.1%, 23.8%, and 4.9% of recyclable waste in the clinical waste stream for each of the three bin audits respectively. In the general waste stream, the two bin audits of this stream revealed 14.3% and 44.4%, respectively. The reasons were identified in the interviews: there were no recycling bins in the main dispensing areas and there was confusion surrounding correct disposal of original containers and non‐contaminated packaging waste. Non‐paper waste was found in the confidential (shredded) waste stream in the two bin audits of this stream (10.1% and 16.7%, respectively).ConclusionProvision of commingled recycling bins and clean office paper waste bins in dispensing areas and education of staff on correct waste segregation processes will improve waste segregation in hospital pharmacy departments with both financial and environmental benefits for the hospital and the general population.

What makes people hesitant from circularity: An analysis of risk, marketing mix, cost and inconvenience

AbstractThe circular economy (CE) concept has attracted significant research and practical momentum. Nevertheless, knowledge about its relationships to consumption and disposal from consumers' standpoint is still fragmented. Most CE consumer‐centric research ends with a consumer's intention to purchase. As a result, this study intends to fill several research gaps by presenting a framework that goes beyond purchase intention and, consequently, incorporates both actual purchase behaviour and circular disposal, as well as their predictors. We gathered survey data from 489 Indian consumers and the proposed research claims were tested by adopting a structural equation modelling approach. The findings demonstrate that pricing advantage and product quality negatively impact perceived risk and positively impact perceived value. The main results confirm that the perception towards marketing mix plays a significant role in generating positive purchase intention. Furthermore, the indirect influence of the perception towards marketing mix on actual purchase behaviour is stronger than the direct influence. Both actual purchase behaviour and disposal convenience positively impact circular disposal behaviour. Meanwhile, the higher disposal costs discourage customers from circular disposal. This research has important implications for researchers and managers seeking to understand how to foster the circularity rate among consumers.

Proposed solutions for marine debris in the Windward Islands- perspectives from key policy makers and policy influencers

With the rise of regionalization and globalized approaches to dealing with the associated sources and impacts of marine debris, it is often a challenge to properly capture the unique context and special needs of small island developing states (SIDS) worldwide. In the SIDS context, locals’ perspectives should have a voice in scientific research, as well as in devising potential solutions, at all and different scales. With the view to tailor solutions for the prevention, reduction and mitigation of marine debris, this research explores the professional opinion of local knowledge holders including policy makers from government organizations (GOs) and key policy influencers in non-governmental organizations (NGOs) in the five English-Speaking Windward Islands of the Eastern Caribbean. To achieve that objective, surveys were conducted with these two groups in Barbados, Dominica, Grenada, St. Lucia and St. Vincent and the Grenadines. On the causes of the debris problem, the survey revealed that the lack of a proper waste management systems on islands, recycling limitations and inappropriate disposal behaviors of the population are generally thought to be the main contributory factors to the accelerating problem of marine debris. Further, phenomena such as Sargassum influxes, sea level rise and extreme weather events exacerbate the problem including most especially tropical storms and hurricanes. On the recommended solutions, over eighty percent of the participants identified monitoring and policing services as a main constraint that prohibits sound coastal and marine litter handling. Ninety-five percent identified establishing feasible recycling systems and sixty-seven percent identified changing social behaviors (including a combination of product and consumer literacy, disposal habits, compliance with laws and regulations) as national priorities for enabling on-the-ground actions for better coastal and marine litter prevention and reduction going forward. These findings reinforce recently published work which indicates the need for effective solid waste management systems in the Eastern Caribbean for cleaner and healthier oceans. An additional recommendation was proposed to address a major source of the marine litter problem- upstream producers. Furthermore, given the natural events component, this research proposes incorporating the Sendai Framework for disaster risk reduction in future proposed mitigation measures with a view to building the resilience of SIDS and local communities in combating the impacts of marine debris.

Embedding Ecopreneurial Behaviour: Proposed Social Marketing Interventions From Value-In-Behaviour Perceptions of Plastic Waste Ecopreneurs

Background Plastic waste is a growing social and environmental problem in developing economies due to poor waste management infrastructure and improper disposal behaviours. This study explores how ecopreneurship can be embedded as a long-term strategy for managing plastic waste in Zimbabwe. Focus of the Article This study focuses on Zimbabwe, a developing country that is grappling with plastic waste. Value-in-behaviour perceptions of plastic waste ecopreneurs were explored. Research Questions This study attempts to answer the following questions: (1) What are the specific set of values that motivate ecopreneurs to start ecopreneurial ventures in Zimbabwe? (2) What are the challenges confronting ecopreneurs in Zimbabwe? (3) What is the potential role of social marketing as a strategy intervention to embed ecopreneurial behaviour in Zimbabwe? Importance to the Social Marketing Field This study extends the value-in-behaviour theory to deepen the current understanding of the relationship between ecopreneurship and social marketing in the context of a developing economy. Methods A qualitative research method was employed. Twenty-one in-depth interviews were conducted with ecopreneurs in Zimbabwe involved in plastic waste collection, recycling and eco-innovations. Interview data was analysed using thematic analysis. Findings Economic value, social value and ecological value emerged as the major value perceptions that motivate ecopreneurs. Funding, limited availability of plastic waste management infrastructure, low market value affixed to eco-innovations, derogatory connotations associated with waste collection and lack of community based support in sorting plastic waste were identified as the major stumbling blocks. Recommendations for Research or Practice Social marketing interventions for embedding ecopreneurial behaviour in Zimbabwe are proposed. Ecopreneurship may be promoted by disseminating educational messages that emphasize on economic, social and ecological benefits. Challenges confronting ecopreneurs such as lack of funding and plastic waste management infrastructure need to be addressed. Limitations This study focused only on ecopreneurs in plastic waste management. Thus, the findings cannot be generalised to ecopreneurs involved in other forms of ecopreneurship. Secondly, the study was conducted in a developing economy where waste collection infrastructure is limited.

Mediating Effect of COVID-19 Pandemic on Single Use Plastic Production, Usage and Disposal Management Models Correlations

This research examines the consequences of the COVID-19 epidemic on the production, use, and disposal of single-use plastics. This research explores the intricate relationships between the impacts of COVD-19 on single-use plastic production, usage, and waste management with a focus on the mediating effects of the pandemic related to model parameters and correlations to develop a trustworthy approach. The report examines first the increasing evidence regarding the pandemic’s influence on various users and industries, and then the consequences for waste management and the environment. The research then examined the relationships and modelling framework correlations between the variables utilised to estimate the influence of COVID-induced changes in production, consumption, and management on single-use plastics. The study variables captured the influence of production, usage, and disposal on the environment. The study’s parameters are equally linked to types of usage, have a pronominal effect, and disposal plays a vital role in the environmental impact, which makes them extremely dynamic for parameters in this study. Single-use plastic aggregation in the environment is predicted to be a dominant mechanism by disposal behaviour.

The effect of local consensus and group integration on rural residents’ household waste classification and disposal behavior

The effect of local consensus and group integration on rural residents’ household waste classification and disposal behavior
