Reduction
Many problems in the cities of the global South are often associated with a weak or inadequate SWM system, which leads to severe direct and indirect environmental and public health issues at every stage of waste collection, handling, treatment, and disposal [ 30 , 31 , 32 , 33 , 34 ]. Inadequate and weak SWM results in indiscriminate dumping of waste on the streets, open spaces, and water bodies. Such practices were observed in, for example, Pakistan [ 35 , 36 ], India [ 37 ], Nepal [ 38 ], Peru [ 39 ], Guatemala [ 40 ], Brazil [ 41 ], Kenya [ 42 ], Rwanda [ 43 ], South Africa [ 44 , 45 ], Nigeria [ 46 ], Zimbabwe [ 47 ], etc.
The problems associated with such practices are GHG emissions [ 37 , 48 ], leachates [ 40 , 44 , 49 ], the spread of diseases such as malaria and dengue [ 36 ], odor [ 35 , 38 , 50 , 51 ], blocking of drains and sewers and subsequent flooding [ 52 ], suffocation of animals in plastic bags [ 52 ], and indiscriminate littering [ 38 , 39 , 53 ].
Uncollected and untreated waste has socioeconomic and environmental costs extending beyond city boundaries. Environmental sustainability impacts of this practice include methane (CH 4 ) emissions, foul odor, air pollution, land and water contamination, and the breeding of rodents, insects, and flies that transmit diseases to humans. Decomposition of biodegradable waste under anaerobic conditions contributes to about 18% and 2.9% of global methane and GHG emissions, respectively [ 54 ], with the global warming effect of about 25 times higher than carbon dioxide (CO 2 ) emissions [ 55 ]. Methane also causes fires and explosions [ 56 ]. Emissions from SWM in developing countries are increasing due to rapid economic growth and improved living standards [ 57 ].
Irregular waste collection also contributes to marine pollution. In 2010, 192 coastal countries generated 275 million metric tons of plastic waste out of which up to 12.7 million metric tons (4.4%) entered ocean ecosystems [ 58 ]. Moreover, plastic waste collects and stagnates water, proving a mosquito breeding habitat and raising the risks of dengue, malaria, and West Nile fever [ 56 ]. In addition, uncollected waste creates serious safety, health, and environmental consequences such as promoting urban violence and supporting breeding and feeding grounds for flies, mosquitoes, rodents, dogs, and cats, which carry diseases to nearby homesteads [ 4 , 19 , 59 , 60 ].
In the global South, scavengers often throw the remaining unwanted garbage on the street. Waste collectors are rarely protected from direct contact and injury, thereby facing serious health threats. Because garbage trucks are often derelict and uncovered, exhaust fumes and dust stemming from waste collection and transportation contribute to environmental pollution and widespread health problems [ 61 ]. In India’s megacities, for example, irregular MSW management is one of the major problems affecting air and marine quality [ 62 ]. Thus, irregular waste collection and handling contribute to public health hazards and environmental degradation [ 63 ].
Most municipal solid waste in the Global South goes into unsanitary landfills or open dumps. Even during the economic downturn during the COVID-19 pandemic, the amount of waste heading to landfill sites in Brazil, for example, increased due to lower recycling rates [ 64 ]. In Johor, Malaysia, landfilling destroys natural habitats and depletes the flora and fauna [ 65 ]. Moreover, landfilling with untreated, unsorted waste led to severe public health issues in South America [ 66 ]. Based on a study on 30 Brazilian cities, Urban and Nakada [ 64 ] report that 35% of medical waste was not properly treated before disposal, which poses a threat to public health, including the spread of COVID-19. Landfills and open dumps are also associated with high emissions of methane (CH 4 ), a major GHG [ 67 , 68 ]. Landfills and wastewater release 17% of the global methane emission [ 25 ]. About 29 metric tons of methane are emitted annually from landfills globally, accounting for about 8% of estimated global emissions, with 1.3 metric tons released from landfills in Africa [ 7 ]. The rate of landfill gas production steadily rises while MSW accumulates in the landfill emissions. Released methane and ammonia gases can cause health hazards such as respiratory diseases [ 37 , 69 , 70 , 71 ]. Since methane is highly combustible, it can cause fire and explosion hazards [ 72 ].
Open dumping sites with organic waste create the environment for the breeding of disease-carrying vectors, including rodents, flies, and mosquitoes [ 40 , 45 , 51 , 73 , 74 , 75 , 76 , 77 , 78 , 79 ]. Associated vector-borne diseases include zika virus, dengue, and malaria fever [ 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 ]. In addition, there are risks of water-borne illnesses such as leptospirosis, intestinal worms, diarrhea, and hepatitis A [ 80 , 81 ].
Odors from landfill sites, and their physical appearance, affect the lives of nearby residents by threatening their health and undermining their livelihoods, lowering their property values [ 37 , 38 , 68 , 82 , 83 , 84 ]. Moreover, the emission of ammonia (NH 3 ) from landfill sites can damage species’ composition and plant leaves [ 85 ]. In addition, the pollutants from landfill sites damage soil quality [ 73 , 84 ]. Landfill sites also generate dust and are sources of noise pollution [ 86 ].
Air and water pollution are intense in the hot and rainy seasons due to the emission of offensive odor, disease-carrying leachates, and runoff. Considerable amounts of methane and CO 2 from landfill sites produce adverse health effects such as skin, eyes, nose, and respiratory diseases [ 69 , 87 , 88 ]. The emission of ammonia can lead to similar problems and even blindness [ 85 , 89 ]. Other toxic gaseous pollutants from landfill sites include Sulphur oxides [ 89 ]. While less than 20% of methane is recovered from landfills in China, Western nations recover up to 60% [ 90 ].
Several studies report leachate from landfill sites contaminating water sources used for drinking and other household applications, which pose significant risks to public health [ 36 , 43 , 53 , 72 , 75 , 83 , 91 , 92 , 93 , 94 , 95 ]. For example, Hong et al. [ 95 ] estimated that, in 2006, the amount of leachates escaping from landfill sites in Pudong (China) was 160–180 m 3 per day. On the other hand, a properly engineered facility for waste disposal can protect public health, preserve important environmental resources, prevent clogging of drainages, and prevent the migration of leachates to contaminate ground and surface water, farmlands, animals, and air from which they enter the human body [ 61 , 96 ]. Moreover, heat in summer can speed up the rate of bacterial action on biodegradable organic material and produce a pungent odor [ 60 , 97 , 98 ]. In China, for example, leachates were not treated in 47% of landfills [ 99 ].
Co-mingled disposal of industrial and medical waste alongside municipal waste endangers people with chemical and radioactive hazards, Hepatitis B and C, tetanus, human immune deficiency, HIV infections, and other related diseases [ 59 , 60 , 100 ]. Moreover, indiscriminate disposal of solid waste can cause infectious diseases such as gastrointestinal, dermatological, respiratory, and genetic diseases, chest pains, diarrhea, cholera, psychological disorders, skin, eyes, and nose irritations, and allergies [ 10 , 36 , 60 , 61 ].
Open burning of MSW is a main cause of smog and respiratory diseases, including nose, throat, chest infections and inflammation, breathing difficulty, anemia, low immunity, allergies, and asthma. Similar health effects were reported from Nepal [ 101 ], India [ 87 ], Mexico, [ 69 ], Pakistan [ 52 , 73 , 84 ], Indonesia [ 88 ], Liberia [ 50 ], and Chile [ 102 ]. In Mumbai, for example, open incineration emits about 22,000 tons of pollutants annually [ 56 ]. Mongkolchaiarunya [ 103 ] reported air pollution and odors from burning waste in Thailand. In addition, plastic waste incineration produces hydrochloric acid and dioxins in quantities that are detrimental to human health and may cause allergies, hemoglobin deficiency, and cancer [ 95 , 104 ]. In addition, smoke from open incineration and dumpsites is a significant contributor to air pollution even for persons staying far from dumpsites.
Composting is a biological method of waste disposal that entails the decomposing or breaking down of organic wastes into simpler forms by naturally occurring microorganisms, such as bacteria and fungi. However, despite its advantage of reducing organic waste by at least half and using compost in agriculture, the composting method has much higher CO 2 emissions than other disposal approaches. In Korea, for example, composting has the highest environmental impact than incineration and anaerobic digestion methods [ 105 ]. The authors found that the environmental impact of composting was found to be 2.4 times higher than that of incineration [ 105 ]. Some reviews linked composting with several health issues, including congested nose, sore throat and dry cough, bronchial asthma, allergic rhinitis, and extrinsic allergic alveolitis [ 36 , 106 ].
As discussed in the section above, there are many negative impacts of unsustainable SWM practices on the people and the environment. Although all waste treatment methods have their respective negative impacts, some have fewer debilitating impacts on people and the environment than others. The following is the summary of key implications of such unsustainable SWM practices.
Therefore, measures toward more sustainable SWM that can mitigate such impacts must be worked out and followed. The growing complexity, costs, and coordination of SWM require multi-stakeholder involvement at each process stage [ 7 ]. Earmarking resources, providing technical assistance, good governance, and collaboration, and protecting environmental and human health are SWM critical success factors [ 47 , 79 ]. As such, local governments, the private sector, donor agencies, non-governmental organizations (NGOs), the residents, and informal garbage collectors and scavengers have their respective roles to play collaboratively in effective and sustainable SWM [ 40 , 103 , 107 , 108 ]. The following are key practical recommendations for mitigating the negative impacts of unsustainable SWM practices enumerated above.
First, cities should plan and implement an integrated SWM approach that emphasizes improving the operation of municipalities to manage all stages of SWM sustainably: generation, separation, transportation, transfer/sorting, treatment, and disposal [ 36 , 46 , 71 , 77 , 86 ]. The success of this approach requires the involvement of all stakeholders listed above [ 109 ] while recognizing the environmental, financial, legal, institutional, and technical aspects appropriate to each local setting [ 77 , 86 ]. Life Cycle Assessment (LCA) can likewise aid in selecting the method and preparing the waste management plan [ 88 , 110 ]. Thus, the SWM approach should be carefully selected to spare residents from negative health and environmental impacts [ 36 , 39 , 83 , 98 , 111 ].
Second, local governments should strictly enforce environmental regulations and better monitor civic responsibilities for sustainable waste storage, collection, and disposal, as well as health hazards of poor SWM, reflected in garbage littering observable throughout most cities of the Global South [ 64 , 84 ]. In addition, violations of waste regulations should be punished to discourage unsustainable behaviors [ 112 ]. Moreover, local governments must ensure that waste collection services have adequate geographical coverage, including poor and minority communities [ 113 ]. Local governments should also devise better SWM policies focusing on waste reduction, reuse, and recycling to achieve a circular economy and sustainable development [ 114 , 115 ].
Third, effective SWM requires promoting positive public attitudes toward sustainable waste management [ 97 , 116 , 117 , 118 ]. Therefore, public awareness campaigns through print, electronic, and social media are required to encourage people to desist from littering and follow proper waste dropping and sorting practices [ 36 , 64 , 77 , 79 , 80 , 82 , 91 , 92 , 119 ]. There is also the need for a particular focus on providing sorting bins and public awareness about waste sorting at the source, which can streamline and optimize subsequent SWM processes and mitigate their negative impacts [ 35 , 45 , 46 , 64 , 69 , 89 , 93 ]. Similarly, non-governmental and community-based organizations can help promote waste reduction, separation, and sorting at the source, and material reuse/recycling [ 103 , 120 , 121 , 122 ]. In Vietnam, for example, Tsai et al. [ 123 ] found that coordination among stakeholders and appropriate legal and policy frameworks are crucial in achieving sustainable SWM.
Fourth, there is the need to use environmentally friendly technologies or upgrade existing facilities. Some researchers prefer incineration over other methods, particularly for non-recyclable waste [ 44 , 65 ]. For example, Xin et al. [ 124 ] found that incineration, recycling, and composting resulted in a 70.82% reduction in GHG emissions from solid waste in Beijing. In Tehran city, Iran, Maghmoumi et al. [ 125 ] revealed that the best scenario for reducing GHG emissions is incinerating 50% of the waste, landfilling 30%, and recycling 20%. For organic waste, several studies indicate a preference for composting [ 45 , 51 , 75 ] and biogas generation [ 15 , 42 , 68 ]. Although some researchers have advocated a complete ban on landfilling [ 13 , 42 ], it should be controlled with improved techniques for leak detection and leachate and biogas collection [ 126 , 127 ]. Many researchers also suggested an integrated biological and mechanical treatment (BMT) of solid waste [ 66 , 74 , 95 , 119 ]. In Kenya, the waste-to-biogas scheme and ban on landfill and open burning initiatives are estimated to reduce the emissions of over 1.1 million tons of GHG and PM2.5 emissions from the waste by more than 30% by 2035 [ 42 ]. An appropriately designed waste disposal facility helps protect vital environmental resources, including flora, fauna, surface and underground water, air, and soil [ 128 , 129 ].
Fifth, extraction and reuse of materials, energy, and nutrients are essential to effective SWM, which provides livelihoods for many people, improves their health, and protects the environment [ 130 , 131 , 132 , 133 , 134 , 135 , 136 ]. For example, recycling 24% of MSW in Thailand lessened negative health, social, environmental, and economic impacts from landfill sites [ 89 ]. Waste pickers play a key role in waste circularity and should be integrated into the SWM system [ 65 , 89 , 101 , 137 ], even to the extent of taking part in decision-making [ 138 ]. In addition, workers involved in waste collection should be better trained and equipped to handle hazardous waste [ 87 , 128 ]. Moreover, green consumption, using bioplastics, can help reduce the negative impacts of solid waste on the environment [ 139 ].
Lastly, for effective SWM, local authorities should comprehensively address SWM challenges, such as lack of strategic SWM plans, inefficient waste collection/segregation and recycling, insufficient budgets, shortage of qualified waste management professionals, and weak governance, and then form a financial regulatory framework in an integrated manner [ 140 , 141 , 142 ]. Effective SWM system also depends on other factors such as the waste generation rate, population density, economic status, level of commercial activity, culture, and city/region [ 37 , 143 ]. A sustainable SWM strives to protect public health and the environment [ 144 , 145 ].
As global solid waste generation rates increase faster than urbanization, coupled with inadequate SWM systems, local governments and urban residents often resort to unsustainable SWM practices. These practices include mixing household and commercial garbage with hazardous waste during storage and handling, storing garbage in old or poorly managed facilities, deficient transportation practices, open-air incinerators, informal/uncontrolled dumping, and non-engineered landfills. The implications of such practices include air and water pollution, land degradation, climate change, and methane and hazardous leachate emissions. In addition, these impacts impose significant environmental and public health costs on residents with marginalized social groups affected mostly.
Inadequate SWM is associated with poor public health, and it is one of the major problems affecting environmental quality and cities’ sustainable development. Effective community involvement in the SWM requires promoting positive public attitudes. Public awareness campaigns through print, electronic, and social media are required to encourage people to desist from littering and follow proper waste-dropping practices. Improper SWM also resulted in water pollution and unhealthy air in cities. Future research is needed to investigate how the peculiarity of each Global South country can influence selecting the SWM approach, elements, aspects, technology, and legal/institutional frameworks appropriate to each locality.

This study is qualitative research that center on the assessment of the solid waste management program in Bacon District in the school year 2017-2018. A total enumeration of 184 is the respondents of the study. The study focus on the activities undertaken by the schools, extent of implementation along with waste segregation, collection, re-use, reduction, recycle and compost. It includes also the problems met during the implementation of the program. Findings reveal that most of the activities undertaken by the schools to implement solid waste management programs were conduct on solid waste management campaigns, incorporate solid waste management in the lessons and activities that prioritize recycling, reduction and re-use. The extent of implementation along waste segregation is highly implemented while in terms of collection, re-use, reduce, recycle and composting is implemented. The study also reveals shortcomings in connection with the implementation of the program such as lack of facility to process recyclable materials, attitudes and awareness of the pupils when it comes to solid waste management, lack of training on recycling and composting of waste, inadequate and insufficient waste collection equipment and lack of resources or fund in maintaining Solid Waste Management Program. A project Waste Management Practices: A key to sustainable Solid Waste Management Program as the output of the study shall be proposing to address the said issues.

The article is based on the project activities done by Vatsalya, an NGO based in Lucknow from February 2019 to March 2019 on recycling of waste. The name of the project was "Mission Recycle" that was supported by Plan India. The project was operational as "My school mission recycling as a WASH issue related activity in the Government primary schools in Mall block of Lucknow district of Lucknow, Uttar Pradesh.There was one objective and 5 expected results of the study. The objective of the study on which the report is based was "Creating Awareness amongst the children and teachers of government schools towards recycle and reuse of PET (Polyethylene Terephthalate) waste". The five results that the study expected out of the activities done by the project were to increase awareness amongst students about recycle and reuse of PET. The second objective was to increase awareness about recycling and waste-reuse related activities. The third was to increase participation of schools at district and state level competitions on recycle and reuse. The fourth focused on cadre of trained teachers who will regularly engage the students in recycling activities and create curriculum/lesson plans that focus on the importance of recycling and re-use. The fifth centred on the quantity of PET & plastics being better managed at the end of the project for appropriate disposal / recycling.

Psychology and Education
This study aimed to evaluate the implementation of solid waste management (SWM) in public secondary schools within the Municipality of Matnog, Sorsogon, during the school year 2021-2022. The research focused on four key aspects of SWM: waste minimization, waste segregation, waste storage and collection, and waste disposal, as perceived by students, teachers, and school administrators. Additionally, the study sought to identify significant differences in perceptions among these groups and to propose an intensified action plan based on the findings. A descriptive research design was employed, utilizing a questionnaire adapted from the Department of Environment and Natural Resources (DENR) manual. The study involved 213 respondents, including school principals, assistant principals, head teachers, and students from four public secondary schools. Data were analyzed using weighted mean and ANOVA to determine the level of implementation and the significance of differences in perceptions among respondents. The results revealed varying levels of SWM implementation across the four domains. School administrators generally perceived the implementation as highly implemented, while teachers and students perceived it as moderately to slightly implemented. Significant differences were found between the perceptions of students, teachers, and administrators in waste minimization, storage, collection, and disposal, but not in waste segregation. The study underscores the need for an intensified SWM action plan to address the disparities in implementation and to enhance waste management practices in the schools and the broader community. These findings provide valuable insights for the Department of Education, local government units, and other stakeholders to strengthen SWM efforts in public secondary schools in Matnog.

The purpose of this study was to evaluate the implementation of Ecological Solid Waste Management Program (ESWMP). The study was conducted to find out the mass of wastes generated from Senior High School students, the mass of waste diverted to composting, recycling, residual, and special, and the perception of the students towards the implementation of ESWMP. The study utilized descriptive research design. Purposive sampling technique was employed to find out the mass of generated waste in SHS while random sampling technique was employed to the selection of respondents of the study. A total of 399 students (205 grade 11 and 194 grade 12 students) were drawn from the population of 796 students. Two research instruments were utilized in the study. To facilitate the analysis of data, Mean was used.

ABSTRACT THE LEVEL OF AWARENESS AND EXTENT OF PARTICIPATION ON WASTE DISPOSAL AND SEGREGATION IMPLEMENTATION IN THE SECONDARY SCHOOLS IN THE MUNICIPALITY OF DON CARLOS by Nelma B. Limpot, Master of Arts in Teaching, Major in Social Studies, Valencia Colleges (Bukidnon) Incorporated, Valencia City, Bukidnon. March 2016. Adviser: Elpedio Y. Lomarda, PhD This research aimed to gather data on the level of awareness and extent of participation in the programs on the implementation of waste disposal and segregation among secondary schools as perceived by the students in the five secondary schools of the Municipality of Don Carlos, Province of Bukidnon. This was conducted to help the country in finding solutions on the worst situation of our environment. Problems stated in this book had been answered according to the data gathered. The design used in this study was quantitative-descriptive- correlation research method in which interpretation of data involved the assignment of numerical values to variables. It utilized a researcher-made questionnaires as instrument in gathering the data needed from the respondents who were composed of students from different levels. The data gathered were tabulated and analyzed through the Statistical Package for Social Sciences (SPSS). The scoring procedure was done through the five-point Likert’s Scale. It used mean, frequency count, standard deviation, and percentage to determine the profile of the respondents in terms of age; gender; and grade level; level of awareness on the implementation of waste disposal and segregation in different secondary schools as perceived by the students; and the extent of participation of students on government programs on waste disposal. Standard deviation, and one-way ANOVA (Analysis of Variance) were utilized to find out the significant difference in the level of awareness and the extent of participation in the programs on the implementation of waste disposal and segregation when grouped according to profile and the significant relationship between the level of awareness and the extent of participation in the programs on implementation of waste disposal and segregation among the secondary schools as perceived by students. This study found out that there were more male respondents than female. Majority of the students are aged 14-16 years old. Most of the respondents are Grade 9 but almost equaled with the Grade 10 students. The level of awareness of students on waste management was with high extent and the extent of participation in the programs on the implementation of waste disposal and segregation in the secondary schools as perceived by the students was described as qualitatively high. It found out that there was a significant difference in the level of awareness on the implementation of waste disposal and segregation when grouped according to profile in terms of age non-significant in terms of gender. In the extent of participation in the programs on the implementation of waste disposal and segregation when grouped according to profile in terms of age and gender had been found out to be with significant difference. The test of significant relationship between the level of awareness and the extent of participation in the programs on the implementation of waste disposal and segregation among secondary schools as perceived by students was found to be significant. Through the findings gathered, the following were strongly recommended by this study: In order to elevate the level of awareness of secondary schools on waste disposal and segregation municipal officials, concerned government agencies, school administrators, non-government organizations, parents, teachers, and student should join forces to ensure full dynamic enforcement. The Department of Education, specifically the Division of Bukidnon planning officials should consistently appraise school performance. School administrators should include in their organization, the participation of the surrounding community, parents, and other stakeholders to advocate the proper waste disposal and segregation. Teachers should also take account of imparting the knowledge proper waste disposal and segregation and emphasize the benefits we can acquire when we apply it to our day to day life. Community should also accept their role as the laboratory of the students in testing what was learned in the four corners of the classroom, and adapt the scientific learning brought by the students to more widen the implementation of the studied government project.

Solid waste management is one of the challenges faced by many countries. Poor solid waste management will lead to various problems in health, environment and socio-economic aspects. Since, educational institution is an agent of change and through R.A. No. 9003, solid waste management concepts are being integrated in science education. In this study, descriptive – quantitative approach was utilized using the researcher made instrument - Solid Waste Management Awareness and Practices Questionnaire (SWMAPQ). A total of 332 Grade 12 students participated in the study from a State College, of which 68 are Science, Technology, Engineering and Mathematics (STEM) students, 166 are Technical Vocational Livelihood (TVL) students and 98 are General Academic Strand (GAS) students. Result shows that students have enough knowledge in terms on definition of solid waste, effect of improper solid waste disposal, solid waste prohibited activities, school initiatives towards solid waste, importance of solid waste management and students’ responsibilities. However, students have low knowledge on the different laws relevant to solid waste management. Television or radio, parents and social media are the sources of these awareness. The result also shows that students have good solid waste management practices in terms on segregation, reduction, reuse, recycle and disposal.

Efficient and effective handling of solid waste in educational institutions starts with determining its composition and methods adopted for disposal. Mapping of solid waste was carried out in four stages-(1) Nature of solid waste generated, (2) segregation of solid waste, (3) management of solid waste; and (4) quantum of waste disposed. The waste generated was categorized under 8 major heads (waste paper, plastic, electronics, furniture, garden, food, textiles and other wastes) and sub-heads to understand the waste stream from generation to final treatment and disposal. Results revealed that most of the waste generated in school was gathered at the main collection point of the school without segregation. Furniture and garden waste were the only two categories sorted/ segregated. More than half of the waste produced in selected schools was regularly discarded (51.60%), however, data also revealed that 15.17% of this waste was organic in nature which has the potential to be recycled to reduce the overall impact on the environment. In the light of the results obtained, it is essential to understand the need for incorporating corrective measures aimed at improving solid waste treatment and increasing awareness among school children.
