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.

Perceived social, economic, environmental and health effects of solid waste management practices in logia town, afar, ethiopia

Improper solid waste management in urban and semi-urban areas has led to adverse impacts on the environment, public health, and the economic well-being of communities. Therefore, this study analyzes the status of household solid waste management practices and their effects in Logia Town, Afar, Ethiopia. To achieve this objective, the study utilizes both descriptive and econometric models (binary logistic regression model). The descriptive results of the study revealed that there is general awareness of the importance of solid waste management (SWM) and its impact on the environment, economy, and human health among the respondents. Regarding respondents’ attitudes, the majority of households understand the responsibility of proper waste disposal and its impact. However, in terms of solid waste management practices, 80% of households do not properly segregate their waste, 59.3% do not separate solid waste (SW) before disposal, and 74% of households engage in improper disposal practices. About 95.9% of respondents were aware that improper waste management can lead to diseases such as diarrhea, typhoid, and cholera. Around 65% of the sampled households considered solid waste as a source of wealth, and, as a result, 56% of them reuse, recycle, and reduce waste. This indicates that solid waste has economic value for society. Regarding the environmental impact of SW, about 89% of respondents argued that SW adversely affects the environment by polluting rivers, lakes, wells, and air. This environmental impact negatively affects the well-being and economic status of the community. The binary logistic regression model found that having adequate solid waste landfills, access to door-to-door solid waste collection, knowledge of SWM rules and regulations, treating waste as a resource, and understanding the 3Rs (recycle, reuse, reduce) had positive and significant effects on the adoption of proper solid waste management practices in the study area. Therefore, to reduce undesirable effects and improve the value of SW, the relevant authorities should provide adequate solid waste landfills and door-to-door collection services, create awareness about SWM rules and regulations, and promote knowledge of the 3Rs.

ANALYTICAL ASPECTS AND SIGNIFICANCE OF MUNICIPAL SOLID WASTE GENERATION, MANAGEMENT PRACTICES AND PLANNING FOR RURAL AREAS

Solid Waste Management practices has been increased after keen initiatives of Government in the form of reforms, policies, regulations and laws. Actually cleanliness in a city is an attribute to the living beings and system adopted for cleanliness. Solid waste is mainly the dry form of refuse. The average density of the solid waste generated is around 300 to 600 Kg/ Cu.meter. Municipal Solid waste is usually collected by the carts, auto rickshaws, tractors and some special buses meant for this purpose only. These types of conventional practices have been redefined and performed in modern era too. The management of the solid waste’s collection, conveyance, transport, disposal or reuse, mode of disposal or reuse comprises the role of Municipality. It is just not a practice to collect the solid waste from each and every houses and then to dump at a place outskirts of a city. This management of the municipal solid waste should be incorporated equipped and comprises of additional art, science and technological use. Municipal solid waste management is an art of planning managing he various activities involved to dispose the solid wastes in dry form or wet form. Mainly the solid wastes are in dry form. In the present study efforts have been made to propose a plan of municipal solid waste management for total areas which could be better and efficient than the conventional approaches adopted for solid waste management. Also it was found during study that no one method of disposal of solid waste could be adopted perfectly but it must be a practice to adopt the combination of different methods of solid waste management especially in rural areas.

Assessment of household solid waste characteristics, quantity, and management practices in Dangila Town, Ethiopia.

Solid waste refers to the material that is discarded because of human activity. In developing countries like Ethiopia, rapid urbanization leads to the production of large amounts of solid waste in towns. As a consequence, it causes severe problems to human health, aesthetics, and the environment, particularly in Dangila Town. Therefore, this study aimed to assess household solid waste characteristics, quantity, and management practices. Data was collected for seven days in January 2020 from 73 households, which were divided into three income groups. Observations, interviews, field measurements, sorting, and open-ended questionnaires were used as data collection tools. The research showed that food waste and ash and dust were the most dominant fractions, comprising 41.04% and 26.18%, respectively. It was also revealed that 77.88%, 12.74%, and 9.38% of household solid waste was decomposable, recyclable, and disposable waste, respectively. Furthermore, the waste components showed a significant statistical difference among income groups, except for the metal and miscellaneous groups. The quantification result indicated that the per capita household generation rate was 0.26kg/day. The management practice assessment found that most households did not practice integrated solid waste management options. They disposed of waste indiscriminately, leading to environmental pollution. The results of this study suggest that the municipality needs to create awareness among households regarding proper solid waste management practices. It is crucial to apply appropriate solid waste management mechanisms and establish a well-organized institution that will collect solid waste in the town and achieve a circular economy.

Solid waste management awareness and practices in coastal communities

Effective solid waste management (SWM) is paramount for environmental sustainability and public health, particularly in coastal communities. This cross-sectional descriptive study determines SWM awareness and practices among 399 households in selected coastal barangays in the City of Mati, Davao Oriental, Philippines. Employing a structured four-point Likert-type survey through KoboCollect applications, this study evaluates SWM awareness and practices while examining the impact of socio-demographic factors on these aspects. The results reveal moderate SWM awareness (X̄=2.55) and practices (X̄=2.66) in these coastal communities, indicating a baseline level of environmental consciousness and waste management efforts. However, there was lack of familiarity with legal and regulatory frameworks (X̄=1.97), including the Republic Act 9003 and local ordinances related to SWM. Notable gaps are also identified in SWM practices, mainly in waste segregation (X̄ = 2.55) and avoidance to waste-burning (X̄=2.56). Socio-demographic factors, such as age, educational attainment, household size, and family income, significantly influence SWM awareness and practices. These findings underscore the need for targeted educational campaigns and community engagement strategies to enhance awareness of SWM regulations. Addressing these gaps is necessary for developing effective interventions to promote sustainable waste management practices in these coastal areas, thus protecting marine ecosystems and supporting the well-being of local communities.

Based on this research results, recommendations are made to improve gender involvement in solid waste management for sustainable development in Ibadan, Nigeria.

The Impact of Solid Waste Management Practices on Vector-Borne Disease Risk in Thiruvanathapuram

Vector-borne diseases (VBDs), including dengue, chikungunya, and malaria, present ongoing public health challenges, particularly in urban areas of tropical regions. Thiruvananthapuram, the capital city of Kerala, has seen a concerning rise in VBD cases, correlating with the city's rapid urbanization and inadequate solid waste management (SWM) practices. Poorly managed waste contributes to the proliferation of disease vectors, such as mosquitoes, by providing ideal breeding grounds, thereby exacerbating the risk of disease transmission. Despite the known association between inadequate SWM and VBDs, there is a paucity of localized studies that quantitatively examine this relationship in Thiruvananthapuram. This study seeks to bridge this gap by investigating the impact of existing SWM practices on the incidence of VBDs in the city. The findings aim to inform public health strategies and policy interventions that can mitigate the risk of VBDs through improved waste management. This cross-sectional study was conducted across 20 wards in Thiruvananthapuram, selected based on their varying levels of SWM effectiveness and reported VBD cases. Data collection involved field surveys to assess SWM practices, structured interviews with residents, and observational studies to identify potential breeding sites for vectors. Health records were analyzed to map the distribution of VBD cases in these wards. Statistical analyses, including correlation and regression, were employed to explore the relationship between SWM practices and VBD incidence. The study revealed a significant correlation between poor SWM practices and elevated VBD risk. Wards with inadequate waste management infrastructure exhibited a 40% higher incidence of dengue and chikungunya cases compared to areas with better-managed waste disposal systems (p < 0.01). Notably, 65% of households in the high-risk wards were found to dispose of waste improperly, contributing to the creation of vector breeding sites. Additionally, only 42% of residents were aware of the link between improper waste disposal and increased VBD risk, highlighting a critical gap in public awareness. This study concludes that inadequate SWM practices are a major contributor to the elevated risk of VBDs in Thiruvananthapuram. Addressing these challenges through improved waste management infrastructure and increased public awareness is crucial for reducing disease incidence. The outcomes of this research provide essential insights for local authorities and policymakers, emphasizing the urgent need for effective interventions to combat VBDs in urban areas.

This indicates a positive application of their knowledge in everyday activities, contributing to effective SWM at the college.

Solid health care waste management practice in Ethiopia, a convergent mixed method study

IntroductionHealthcare waste is any waste generated by healthcare facilities that is considered potentially hazardous to health. Solid healthcare waste is categorized into infectious and non-infectious wastes. Infectious waste is material suspected of containing pathogens and potentially causing disease. Non-infectious waste includes wastes that have not been in contact with infectious agents, hazardous chemicals, or radioactive substances, similar to household waste, i.e. plastic, papers and leftover foods.This study aimed to investigate solid healthcare waste management practices and develop guidelines to improve solid healthcare waste management practices in Ethiopia. The setting was all health facilities found in Hossaena town.MethodA mixed-method study design was used. For the qualitative phase of this study, eight FGDs were conducted from 4 government health facilities, one FGD from each private health facility (which is 37 in number), and forty-five FGDs were conducted. Four FGDs were executed with cleaners; another four were only health care providers because using homogeneous groups promotes discussion. The remaining 37 FGDs in private health facilities were mixed from health professionals and cleaners because of the number of workers in the private facilities. For the quantitative phase, all health facilities and health facility workers who have direct contact with healthcare waste management practice participated in this study. Both qualitative and quantitative study participants were taken from the health facilities found in Hossaena town.ResultSeventeen (3.1%) health facility workers have hand washing facilities. Three hundred ninety-two (72.6%) of the participants agree on the availability of one or more personal protective equipment (PPE) in the facility ‘‘the reason for the absence of some of the PPEs, like boots and goggles, and the shortage of disposable gloves owes to cost inflation from time to time and sometimes absent from the market’’. The observational finding shows that colour-coded waste bins are available in 23 (9.6%) rooms. 90% of the sharp containers were reusable, and 100% of the waste storage bins were plastic buckets that were easily cleanable. In 40 (97.56%) health facilities, infectious wastes were collected daily from the waste generation areas to the final disposal points. Two hundred seventy-one (50.2%) of the respondents were satisfied or agreed that satisfactory procedures are available in case of an accident. Only 220 (40.8%) respondents were vaccinated for the Hepatitis B virus.ConclusionHand washing facilities, personal protective equipment and preventive vaccinations are not readily available for health workers. Solid waste segregation practices are poor and showed that solid waste management practices (SWMP) are below the acceptable level.

Indigenous Knowledge Systems of Solid Waste Management in Bushbuckridge Rural Communities, South Africa

Indigenous knowledge systems related to solid waste management in economically marginalized communities have been largely overlooked in the scientific literature, even though the indigenous communities of developing nations struggling to manage solid waste rely on these practices. It is startling that indigenous solid waste management practices are scarcely documented in the scientific literature despite their position as potential alternative disposal methods. This gap persists amid limited municipal budgets, inadequate waste collection services, and poor infrastructure in economically marginalized indigenous rural communities in developing nations. Subsequently, in the discipline of solid waste management, this obstacle impedes the recognition and inclusion of indigenous waste management practices into integrated waste management plans. As a result, this causes a delay in their progress or elevation to the same level of credibility as mainstream scientific knowledge. In the process, this relegates the waste management practices of indigenous communities to the background. Against this background, the current study sought to investigate the indigenous solid waste management practices of rural communities in Bushbuckridge Local Municipality. As such, ten cases that captured the spatial cultural diversity of indigenous communities’ practices across Bushbuckridge Local Municipality (BLM) were selected for sampling. Data were collected using ethnographic research methods. Data analysis was carried out using the thematic analysis approach. Inductive logic was used in the interpretation of the current study results. The results of the current study indicate that indigenous communities of Bushbuckridge Local Municipality, in the absence of formal waste management services from the local authority, resort to an indigenous knowledge system to manage solid waste. Waste burning (100%), open-air dumping (100%), and backyard pits (90%) are some of the indigenous waste management practices espoused by the rural communities of BLM. The similarity in practices was corroborated by statistical inferences that revealed that between BLM communities, the amount of indigenous waste management practices is not significant (p > 0.05). However, there are concerns that despite the sustainability aspect associated with recycling (<25%) practices, these disposal methods are not common in the rural communities of BLM. This is a setback for an indigenous knowledge system that is supposed to advance environmental sustainability practices.

Factors influencing willingness to pay for improved solid waste collection services among households in urban cities in Uganda: empirical evidence from Lira City

Waste management in Lira City, Uganda faces significant challenges, particularly in the area of waste collection. Pollution and health risks from uncollected waste are rampant, posing serious threats to human health and the environment. This persistent problem demands urgent attention and effective solutions to improve waste collection and safeguard the well-being of the community and the natural surroundings. This study aimed to assess households’ willingness to pay for improved waste collection services, examine their waste management practices, and identify influencing factors. We employed a multistage sampling technique to randomly select 585 household heads and conducted key informant interviews with city officials and private waste collectors. Data analysis was conducted with STATA 17 and results showed that 48.12% of households were willing to pay an average of UGX 3012 ($0.84) per month for better services. Factors including education level, occupation, distance to waste collection sites, and environmental awareness significantly influenced this willingness. The study highlights a significant gap in public awareness and understanding of efficient solid waste management practices and concludes that enhancing public awareness is crucial for improving environmental health and safety in Lira City.
