COMMUNITY ENGAGEMENT ON WASTE MANAGEMENT: EMPOWERING LOCAL COMMUNITIES FOR SUSTAINABLE WASTE DISPOSAL

The research focused on assessing the waste disposal practices of residents and the waste management initiatives of the barangay council or community in Hugpa, Biliran. It specifically examined respondents' solid waste management practices in areas such as segregation, waste reduction, recycling and reuse, as well as the community's waste management activities. To collect data, the study employed a survey questionnaire as the primary instrument. A total of 30 respondents participated in the data collection process. The study utilized the descriptive research method, relying on surveys to gather information. Data were analyzed using statistical measures, specifically the weighted mean. The findings revealed that respondents rated their solid waste management practices, including segregation, as “moderately practiced.” Similarly, waste reduction and recycling efforts were also evaluated as “moderately practiced.” However, when it came to waste disposal and the broader waste management activities implemented by the barangay council and the community, these were described as “sometimes practiced”. The results indicate that while there is a baseline of moderate engagement in waste management practices, significant improvements are required. The respondents acknowledged the need for enhanced community participation and more effective strategies to strengthen the overall efficiency of waste management efforts. This suggests that while the community is making efforts in waste management, more comprehensive and sustained initiatives, supported by the barangay council, are essential to address gaps and promote better environmental practices.

Implementation of Community-Based Waste Management to Improve Environmental Health in Villages

Waste management has emerged as a critical environmental issue, particularly in rural areas where population growth and changing consumption patterns have led to increased waste generation. This research focuses on the implementation of community-based waste management in villages, aiming to understand its impact on environmental health and the factors influencing program success. Utilizing a quantitative analytic approach with a cross-sectional research design, the study surveyed 4,345 family heads, with a sample size of 98 participants.The findings revealed that 54.1% of respondents did not engage in waste management activities. Among these non-participants, 70.4% had low educational attainment (elementary or junior high school). Additionally, 53.1% cited a lack of infrastructure as a barrier to participation, while 64.3% reported poor knowledge of waste management practices.The results indicated that infrastructure availability significantly influences community participation, with a p-value of 0.006 and an odds ratio (OR) of 3.911. Furthermore, knowledge levels were crucial; those with inadequate knowledge were less likely to participate (69.2% did not engage), whereas those with good knowledge showed higher participation rates (63%).Effective waste management is essential for improving environmental health by reducing pollution and disease risks. Therefore, enhancing education and infrastructure is vital to encourage community involvement in waste management initiatives. This study underscores the importance of addressing knowledge gaps and infrastructural challenges to foster sustainable waste management practices in rural communities.

Characterizations of Some Selected Clay Types for Cost Effective Wastewater Treatments

Water pollution poses a significant challenge to water consumption, particularly in relation to drinking purposes. Various factors such as industrial discharge, improper waste management, waste build-up, and natural activities contribute to the contamination of water bodies. Adequate water treatment plays a crucial role in the preservation of water quality and compliance with environmental regulations. The treatment process typically involves the application of physical, chemical, and biological techniques, with a common reliance on chemical substances and intricate systems. Recent studies have increasingly explored the utilization of cost-efficient natural materials for water treatment, highlighting benefits like affordability, user-friendliness, health advantages, and widespread availability. This particular investigation aimed to assess the suitability of selected natural substances for the treatment of wastewater, focusing primarily on methods like adsorption, absorption, and filtration. A number of earth materials, notably three distinct types of clays prevalent in Sri Lanka, were singled out for examination. The findings unveiled that these clays predominantly consist of over 75% iron in their mineral composition, with certain samples displaying finer particles to enhance porosity and permeability. These raw materials exhibit potential for the fabrication of wastewater treatment systems intended for the elimination of suspended particles, dissolved solids, heavy metals, pathogens, oils, and toxic compounds. Their distinct chemical properties render them appropriate for catalytic reactions and advanced chemical processes

Riverine macroplastic survey along the segments of Tullahan River in Metro Manila, Philippines

The Philippines is one of the world’s main contributors to global marine plastic pollution. However, field data remains scarce, so model estimates of riverine plastic pollution may be inaccurate. This paper aims to characterize the macrolitter observed along the Tullahan River, with focus on plastics, passing through the barangays of Quezon City and Valenzuela City in Metro Manila. The impact of solid waste management and land use activities on plastic flux were also investigated. For the floating litter, visual counting and float method were used to determine the plastic flux and river velocity, respectively. Riverbank litter was collected manually to characterize it based on plastic product and polymer type. Results show that the macroplastic flux was lowest on the site where residential houses are farthest from the stream. Waste characterization revealed that riverbank litter was primarily plastic – 30%–41% were residuals, and 5%–21% were recyclables. Both methods revealed that wrappers and thin PE plastics are the top contributors to riverine macroplastic pollution. Therefore, the entry of macroplastics into the river may be due to land use activities and weak enforcement of existing solid waste management (SWM) policies. The points discussed in the study can help in improving SWM and land use planning. The results can also increase the accuracy of model estimates.

Identifying Strategies to Cultivate Students’ Attitude Towards Circular Economy

Circular economy (CE) in Technical and Vocational Education and Training (TVET) refers to an economic approach that promotes efficient use of resources, material recovery, and waste reduction through vocational education. Despite various activities and programs conducted by TVET instructors to promote the circular economy, reports indicate that students' attitudes towards the environment remain at a moderate level. This paper aims to identify strategies that can be implemented to foster students' interest in practicing the circular economy within the context of TVET. This study uses the Nominal Group Technique (NGT) as an alternative approach to suggest initiatives that can foster students' attitudes towards the circular economy. The process involved silent idea generation, round robin, discussion, two rounds of initial voting, and a final stage survey to determine the priority list. Five content experts participated in the NGT meeting. Initially, 50 strategies were identified. Through the NGT process, 20 important strategies were selected to cultivate students' attitudes towards the circular economy. These strategies include waste management workshops, environmental programs and activities at institutions, conducive public sector ecosystem (EKSA) in institutions, homes and neighborhoods, information boards, simulation outside the classroom, daily routines, campaigns, neighborhood activities, sale of used oil, sale of recycled goods, innovation, waste segregation, cultivating student awareness, application in teaching, motivation, moral support, cleanliness and cheerfulness competitions, environment week, incorporating circular economy in the syllabus, and cross-curricular elements. The identified strategies are expected to assist stakeholders in overseeing the implementation of environmental awareness programs in schools, colleges, and TVET institutions, with the goal of improving student attitudes and transforming TVET education towards greater circular economy awareness.

Formation of an electronic waste management system based on the use of key principles of the best available technologies

Abstract The article substantiates the expediency of the transition of modern industry from a development model based on economic growth to a model built on the principles of the best available technologies (BAT), including the industries responsible for waste management. This is especially true for e-waste management, which is one of the fastest growing categories of waste. Today in Russia, as a transitional stage to the principles of BAT, integrated environmental permits (IEP) issued to enterprises by Russian Environment Ministry are used, which are a document that, in accordance with Art. 31.1 of Federal Law No. 7-FL of January 10, 2002, “is issued for a separate facility that has a negative impact on the environment” and contains a number of requirements and standards enshrined in clause 10 of Article 31.1. Nevertheless, this process is tepid, which is associated both with the lack of development of the issuance procedure itself, and with the non-compliance of the companies’ technological processes with the standards for permissible emissions and discharges. The article formulates the principles that must be observed while issuing an IEP. The procedure for issuing IEPs is considered, its main stages are analyzed. Differences from the similar order in European countries are revealed. The dynamics of issuing IEP for the period from 2019 to 2022, including in the field of waste management, is analyzed. The existing problems in the implementation of waste management activities by regional operators are identified. The analysis and grouping of data on the generation, processing, disposal, neutralization, disposal of production and consumption waste, submitted by Russian companies in the report on the 2-TP form by federal districts, as well as by the category “electronic waste”, was carried out. The structure of these wastes was also analyzed according to hazard class. The increase of the highly hazardous waste mass was found although their share decreased over the specified period. The results obtained made it possible to formulate the most important directions for reforming the system for issuing environmental permits, considering the principles of BAT. Further research will be directed to the formation of a waste management system for the electronics industry at the regional level.

Development of a Seafloor Litter Database and Application of Image Preprocessing Techniques for UAV-Based Detection of Seafloor Objects

Marine litter poses a significant global threat to marine ecosystems, primarily driven by poor waste management, inadequate infrastructure, and irresponsible human activities. This research investigates the application of image preprocessing techniques and deep learning algorithms for the detection of seafloor objects, specifically marine debris, using unmanned aerial vehicles (UAVs). The primary objective is to develop non-invasive methods for detecting marine litter to mitigate environmental impacts and support the health of marine ecosystems. Data was collected remotely via UAVs, resulting in a novel database of over 5000 images and 12,000 objects categorized into 31 classes, with metadata such as GPS location, wind speed, and solar parameters. Various image preprocessing methods were employed to enhance underwater object detection, with the Removal of Water Scattering (RoWS) method demonstrating superior performance. The proposed deep neural network architecture significantly improved detection precision compared to existing models. The findings indicate that appropriate databases and preprocessing methods substantially enhance the accuracy and precision of underwater object detection algorithms.

A local-to-global emissions inventory of macroplastic pollution

Negotiations for a global treaty on plastic pollution1 will shape future policies on plastics production, use and waste management. Its parties will benefit from a high-resolution baseline of waste flows and plastic emission sources to enable identification of pollution hotspots and their causes2. Nationally aggregated waste management data can be distributed to smaller scales to identify generalized points of plastic accumulation and source phenomena3–11. However, it is challenging to use this type of spatial allocation to assess the conditions under which emissions take place12,13. Here we develop a global macroplastic pollution emissions inventory by combining conceptual modelling of emission mechanisms with measurable activity data. We define emissions as materials that have moved from the managed or mismanaged system (controlled or contained state) to the unmanaged system (uncontrolled or uncontained state—the environment). Using machine learning and probabilistic material flow analysis, we identify emission hotspots across 50,702 municipalities worldwide from five land-based plastic waste emission sources. We estimate global plastic waste emissions at 52.1 [48.3–56.3] million metric tonnes (Mt) per year, with approximately 57% wt. and 43% wt. open burned and unburned debris, respectively. Littering is the largest emission source in the Global North, whereas uncollected waste is the dominant emissions source across the Global South. We suggest that our findings can help inform treaty negotiations and develop national and sub-national waste management action plans and source inventories.

Analysis of the Application of Environmental Accounting in Solid Waste Management in Karawang Health Center

This research aims to determine the application of environmental accounting in waste management activities as well as the stages of accounting treatment of environmental costs by referring to PSAK 2015 No.1 carried out by the Karawang Community Health Center. The method used in this research is descriptive qualitative with a case study approach. The results of the research found that the Karawang Community Health Center had incurred costs related to waste management and had managed its waste well, namely in collaboration with third parties. However, the storage of solid or B3 waste at the Karawang Community Health Center is still not in accordance with applicable standards. And in the accounting treatment stages, the Karawang community health center has not fully carried out these stages because there is no specific presentation of environmental cost reports, therefore the Karawang community health center has not implemented environmental accounting properly. The inhibiting factors in implementing environmental accounting at the Karawang Community Health Center are HR (Human Resources), level of understanding and development.

Water, Sanitation, Waste Management, and Professional Activities in Relation to Diseases with Neighboring Citizens of Congo Rivers in the Brazzaville Agglomeration (Republic of Congo)

Situated on the right bank of the Pool Malébo, in the Congo River basin, the city of Brazzaville is rich in potential water resources. These resources are polluted by human practices that deteriorate the quality of the soil and, consequently, the quality of the water. The aim of this study is therefore to inventory the activities carried out by the population around watercourses, to investigate waste management and to assess the impact on water and soil quality. The survey sample was selected on the basis of impacted zones located between 250 m and 750 m around watercourses. The aim of this study is therefore to inventory the activities carried out by the population around watercourses, to investigate waste management and to assess the impact on water and soil quality. The survey form was drawn up using Sphinx Plus2-Edition Lexica-V5 software. The survey data was entered into the same software, then transferred to Excel to generate the graphical. 880 people were surveyed, the most dominant age group was 25-48 years old, i.e. a rate of 66%. The most dominant gender was female, with a rate of 54%. The average age of the respondents was lower secondary school, and they were generally employed in the private sector. Commercial activities (restaurants/bars, pharmacies, grocery stores/ butchers, markets, etc.) are the most common economic activity, with a rate of around 70%; 59% of these activities are located close to or very close to the watercourse (750-1000 m). The activities that contribute to soil degradation, and consequently water degradation, in the city of Brazzaville are: 59% the dumping of household waste and/or wastewater on the ground and 32% uncontrolled urbanization. The study shows that soil and water pollution in Brazzaville is caused by poor management of household waste and uncontrolled urbanization.

Eco-Friendly Urban Design: Investigating Innovative Approaches and Sustainable Construction Practices Across Afghanistan’s Diverse Climate Zones

Climate change serves as a pervasive catalyst globally, significantly influencing urban growth and construction dynamics. The interplay of population growth, heightened consumption, increased waste production, and rising CO2 emissions presents a substantial threat to biodiversity and plant life. Creating vibrant, environmentally conscious cities requires integrating architectural, design, and landscape components into the urban development process. This study employs a descriptive approach to examine the intricate dynamics among urbanism, urbanization, and climate-responsive design across Afghanistan's diverse climatic zones. The findings reveal a significant shift from traditional to contemporary global standards, marking a significant evolution within the construction sector. However, there remains a notable lack of climate awareness, resulting in a gap between evolving construction features and climate-responsive methodologies. The Afghanistan National Environmental Protection Agency’s strategies are often too generalized, failing to address specific climatic requirements effectively. Unplanned urban growth has led to limited access to proper housing, increased poverty, and greater vulnerability to climate impacts. Key issues include uncontrolled carbon emissions from heating, transportation, waste management, and industrial activities, severely affecting precipitation patterns and living quality. The research emphasizes the necessity for tailored climate-responsive design and sustainable construction practices, advocating for integrating green technologies and enhancing regulatory frameworks to promote energy efficiency and reduce the environmental footprint of urban developments in Afghanistan.
