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.
