Quantification of construction and demolition waste disposal behaviors during COVID-19 using satellite imagery

The COVID-19 pandemic disrupted conventional municipal solid waste (MSW) management practices and affected waste generation rates. While MSW streams have been extensively studied and reported, the impact on construction and demolition (C&D) waste remains overlooked. This research develops an innovative analytical framework utilizing satellite imagery to quantify C&D waste disposal rates during COVID-19 restrictions in a mid-sized Canadian city. Supervised classification of Landsat-8 images is conducted to derive the settlement area over a period of 8.8 years (2014–2022). The C&D disposal rates and settlement area relationship is evaluated using regression analysis. Results reveal a 73.4% reduction in mean weekly C&D disposal in 2020 compared to pre-pandemic years, reflecting diminished construction activity. The settlement area exhibits a strong positive correlation (R2 = 0.812) with per capita C&D disposal rate, providing spatial evidence of urbanization patterns affecting C&D waste generation. Among socioeconomic factors examined, the value of building permits issued most influences C&D quantities (R2 = 0.934). The satellite imagery-based approach allows indirect estimation of disrupted C&D waste streams when on-site auditing is restricted during pandemics. The framework offers municipal authorities spatial decision support to formulate data-driven C&D waste management policies that are essential to smart cities and resilient to future public health emergencies.

Can Dynamic Normative Feedback Enhance Household Kitchen Waste Separation? Evidence from Two Field Intervention Studies

Imagine if more and more households in your community started separating waste, would this trend inspire you to do the same? Previous research on social norms has been predominantly static, focusing on individual behavior and neglecting the potential of leveraging group dynamics. To address this gap, we conducted two field studies using group feedback to activate dynamic norms. Using an A-B-A time-series design in two communities, we collected 21,555 observations of waste disposal behavior. During the intervention period, we publicly displayed the weekly changing participation rates of household kitchen waste separation within the community, a strategy referred to as dynamic normative feedback. Both communities experienced a significant increase in participation in waste separation. Furthermore, the feedback effect persisted for up to three months after the intervention was removed. Our findings demonstrate that group dynamic normative feedback could be an effective strategy for promoting long-term separation behavior and have implications for waste management.

Menstrual waste behaviour of young adolescents: a theory of planned behaviour approach

ABSTRACT There is a significant rise in the pile of non-biodegradable menstrual waste. Still, the majority of the studies focused on the variety and quality of menstrual products, and only a few investigated the sustainable and safe disposal of used menstrual material. The theory of planned behaviour serves as the foundation upon which the paper constructs its theoretical framework to study menstrual waste disposal behaviour among adolescents. It finds that a variety of social contexts and circumstances influence adolescents' intentions to dispose of used menstrual products carelessly, indirectly contributing to environmental degradation. This paper is an attempt to examine the existing gap in the literature and understand the attitudes and intentions that underlie such an activity. This paper also suggests ways for policymakers and implementors to influence the behaviour of adolescents resulting in hygienic and environmentally safe disposal of menstrual waste.

Predictors of Students’ Proper Waste Disposal Behavior in School Environment: a Partial Least Squares Structural Equation Modeling Approach

It is evident from various reports and statistics that there is a significant gap between the desired environmental state and the current situation, primarily due to improper waste disposal. This study used a predictive-correlational design and structural equation modeling to examine the predictors of proper waste disposal behavior. The research instrument was validated and used to survey 293 high school students across three public schools in Nueva Ecija, Philippines. Using WarpPLS 8.0, the results revealed that (1) accessibility of trash bins, perceived consequences, environmental concern, and perceived behavioral control predict proper waste disposal behavior, and (2) environmental concern and perceived behavioral control sequentially mediate the effect of perceived behavioral control on proper disposal behavior. This study proposes a structural model with meaningful predictive accuracy that can help educational institutions design effective waste management programs empowering education to promote eco-friendly behavior. Future studies may be conducted to test the revised model presented in this study.

Navigating E-Waste Disposal: Formal Practices among Residents of Bukit Sentosa, Rawang, Selangor

Electronic waste (e-waste) contains harmful materials that require specialized end-of-life handling. This study aims to analyse formal e-waste disposal practices among residents in Bukit Sentosa, Rawang, Selangor. Employing a quantitative research approach, data were collected from 367 respondents residing in Bukit Sentosa to examine the relationship between knowledge, awareness, and attitudes towards e-waste disposal practices. Spearman's correlation test revealed positive correlations between knowledge, attitudes, and awareness, and formal e-waste disposal practices. These findings indicate that improved knowledge, attitudes, and awareness lead to more responsible disposal behaviours, including increased recycling, reduced waste production, and proper disposal of hazardous materials, thereby mitigating environmental pollution. The findings suggest to enhanced public awareness and education can foster better e-waste management practices among urban households. Furthermore, the results highlight the potential for collaboration between policymakers, government agencies, local authorities, and NGOs, contributing to the development of more comprehensive and effective waste management regulations.

Association of Opioid Disposal Practices with Parental Education and a Home Opioid Disposal Kit Following Pediatric Ambulatory Surgery.

The majority of opioid analgesics prescribed for pain after ambulatory pediatric surgery remain unused. Most parents do not dispose of these leftover opioids or dispose of them in an unsafe manner. We aimed to evaluate the association of optimal opioid disposal with a multidisciplinary quality improvement (QI) initiative that proactively educated parents about the importance of optimal opioid disposal practices and provided a home opioid disposal kit before discharge after pediatric ambulatory surgery. Opioid disposal behaviors were assessed during a brief telephone interview pre- (Phase I) and post-implementation (Phase II) after surgery. For each phase, we aimed to contact the parents of 300 pediatric patients ages 0 to 17 years who were prescribed an opioid after an ambulatory surgery. The QI initiative included enhanced education and a home opioid disposal kit including DisposeRX®, a medication disposal packet that renders medications inert within a polymeric gel when mixed with water. Weighted segmented regression models evaluated the association between the QI initiative and outcomes. We considered the association between the QI initiative and outcome significant if the beta coefficient for the change in intercept between the end of Phase I and the beginning of Phase II was significant. Safe opioid disposal and any opioid disposal were evaluated as secondary outcomes. The analyzed sample contained 161 pediatric patients in Phase I and 190 pediatric patients in Phase II. Phase II (post-QI initiative) cohort compared to Phase I cohort reported higher rates of optimal (58%, n = 111/190 vs 11%, n = 18/161) and safe (66%, n = 125/190 vs 34%, n = 55/161) opioid disposal. Weighted segmented regression analyses demonstrated significant increases in the odds of optimal (odds ratio [OR], 26.5, 95% confidence interval [CI], 4.0-177.0) and safe (OR, 4.4, 95% CI, 1.1-18.4) opioid disposal at the beginning of Phase II compared to the end of Phase I. The trends over time (slopes) within phases were nonsignificant and close to 0. The numbers needed to be exposed to achieve one new disposal event were 2.2 (95% CI, 1.4-3.7]), 3.1 (95% CI, 1.6-7.4), and 4.3 (95% CI, 1.7-13.6) for optimal, safe, and any disposal, respectively. A multidisciplinary approach to educating parents on the importance of safe disposal of leftover opioids paired with dispensing a convenient opioid disposal kit was associated with increased odds of optimal opioid disposal.

Medication Disposal Patterns and Practices with Awareness of Environmental Contamination Caused by Pharmaceuticals among the General Public in Malaysia.

The proper disposal of pharmaceuticals has become a prime concern in contemporary healthcare and environmental management. The evolving awareness highlights the ecological and public health risks associated with pharmaceutical waste. Therefore, evaluating medication disposal patterns and public awareness regarding pharmaceutical-related environmental issues is crucial for promoting responsible practices. The primary aim of this study is to identify the determinants of participation in the Medicine Return Program (MRP) among Malaysians. This cross-sectional study employed snowball sampling and an online questionnaire, disseminated via multiple social media platforms. Results: Out of 389 respondents, 46% were 18 to 29 years old, 61% were female, and 69.7% attained a tertiary educational level. Most of them (71.5%) reported disposing of their unused medicines into the rubbish bin, indicating that this disposal method is prevalent among Malaysians. Only 26.2% participated in the MRP program. The study revealed that 73.0% of respondents were aware of pharmaceutical-related environmental contamination. Furthermore, significant associations were demonstrated between a factor of receiving advice from healthcare professionals (p < 0.001), awareness level on environmental pharmaceutical contamination (p < 0.001) and MRP (p < 0.001) and willingness to participate in MRP (p < 0.001) with MRP support. This study provides valuable insights on Malaysian pharmaceutical disposal practices and the factors influencing MRP participation. These findings can inform targeted interventions and public health campaigns to improve medication disposal behaviors and reduce pharmaceutical waste's environmental impact.

Social competition drives collective action to reduce informal waste burning in Uganda

Improving urban air quality is a pressing challenge in the Global South. A key source of air pollution is the informal burning of household waste. Reducing informal burning requires governments to develop formal systems for waste disposal and for residents to adopt new disposal behaviors. Using a randomized experiment, we show that social competitions between pairs of neighborhoods in Nansana municipality, Uganda, galvanized leadership and inspired collective action to reduce informal burning. All 44 neighborhoods in the study received a public health campaign, while 22 treated neighborhoods were paired and competed to reduce waste burning over an 8-mo period. Treated neighborhoods showed a 24 percent reduction (95% CI: 11 to 35 percent) in waste burning relative to control neighborhoods at the end of the competition period. There is no evidence that treated neighborhoods experienced a rebound in waste burning several months after the competitions. Community leaders reported greater effort in coordinating residents and more pride in their neighborhood when assigned to the competition treatment. These results suggest that creating focal points for leadership and collective action can be an effective and low-cost strategy to address policy problems that require broad participation and costly behavior change.

Delivery Garbage Behavior Detection Based on Deep Learning

In the context of rapid urbanization, the challenge of effective garbage disposal has become increasingly significant. Traditional methods for addressing illegal littering by pedestrians are not only inefficient but also resource-intensive, demanding considerable manpower and materials. This study introduces a deep learning-based approach for detecting improper garbage disposal behavior. Leveraging advanced deep learning technologies, this approach focuses on object detection, tracking, and human posture analysis to identify and alert against illegal dumping activities captured in video footage, specifically targeting incidents outside designated times or areas. The primary aim is to facilitate prompt detection and mitigate associated health risks. The system uses three deep learning models, YOLOv5, DeepSORT and MobilePose. YOLOv5 is used to identify the human body and garbage bag, DeepSORT is used to track the two, and MobilePose identifies the key points of the human body for posture estimation. The tracking algorithm is used to determine whether to throw garbage.

This research aims to determine the factors related to household behavior in disposing of waste in Kp. Pulo Timaha RT.08/RW.08 Bekasi Regency 2023. This research is a type of quantitative analytical research using a cross sectional design. Data collection was carried out by means of interviews using questionnaires and observation. The sampling method uses Random Sampling Technique. The sample in this study consisted of 71 Family Cards. The analysis used is univariate and bivariate analysis (ChiSquare Test). Univariat results of respondents with unfavorable behavior were 53 (74.6%), education &gt;9 years as many as 45 (63.4%), poor knowledge as many as 57 (80.3%), negative attitudes as many as 63 (88.7%), socialization of health workers who were not socialized was 48 (67.6%), and infrastructure was not available as many as 52 (73.2%). The results of bivariate research show that there is a relationship with waste disposal behavior, namely household knowledge (Pvalue &lt;0.001 PR=6.389 CI=3.035-13.488), household attitude (Pvalue 0.003 PR=3.938 CI=2.061-7.523), and socialization of health workers (Pvalue &lt;0.001 PR=10.435 CI=3.325-32.483). Meanwhile, there is no relationship between education and infrastructure on waste disposal behavior. Therefore, there is a need for socialization about proper and correct waste disposal to increase household knowledge, attitudes and behavior in disposing of waste.

To Study the Consumption and Disposal Behaviour of Women in Delhi Towards Undergarments

This project aims to study and understand the approach towards undergarments usages and disposal behavior in Indian society (primarily among Indian women). Indian undergarment market is undoubtedly one of the unique markets among the world's primary market today. High functionality and the demand, for now, are the main reason for sudden expansion [1]. The consumption increment ultimately will lead to disposal increment [2]. The industry needs to follow a sustainable method for this small piece of clothing. This research study is an effort to know the consumption &amp; disposal behavior of women towards their undergarments. This research study also helps understand the consumer attitude towards recycling the undergarments &amp; find alternative ways to sustain them. Undergarments are a largely neglected part of women's clothing, which, this research study argues, is nonetheless as important as 'outward' dress. Indeed, undergarments are more interesting in some ways because it is hidden from view, but still appears to have considerable social/discursive importance [3]. The research model used for this research is qualitative, formulated to the conceptual framework, and studied to quantify in numbers. Research methodologies used are historical, Comparative, Descriptive, Correlation (between two results accordingly), and Evaluation.
