Solid Waste Disposal on Inland Water Wetlands

Generation of solid waste precedes the surge of urbanization. The earliest waste dumping is recorded in Greece as early as 500 BCE, the conservancy workers in France, wastewater treatment in London, and aqueduct systems in oriental civilizations. The magnitude of waste has been compounding annually with the rise of global population, urbanization, and economic growth. Waste has been overtly and irresponsibly dumped in inland water bodies and the wetlands around it causing inherent damage to the fluvial, pond, or riverine ecosystems. The United Nations has declared this decade to be for ecosystem restoration, and hence, this chapter intends to ponder and establish the concerns of health, species modification, ecosystem endangering, pollution of the surface and subsurface water, impact on the vegetation along the water stretches, to name a few. The objective of this chapter is to evaluate the impact on the ecospheres while arriving at sustainable restoration options.

Assessment of heavy metal contamination in soil around Piyungan Landfill, Yogyakarta, Indonesia

One of the negative impacts of the landfill as solid waste disposal is soil contamination by heavy metals. This study assessed heavy metals impact, especially Pb, Cu, Zn, and Cd, in the soil in Piyungan landfill, Bantul, Yogyakarta, Indonesia. The assessment was conducted by analyzing 15 soil samples from 25 cm depth in the study area, which was divided into three-zone. The study results showed that generally, the highest content of metals was found in zone II, which is located near or directly situated in a landfill site. The pollution index (PI) calculated showed in order Cd>Cu>Pb>Zn. The result also indicates that Cd has the highest pollution index and even the highest risk compared to Pb, Cu, and Zn. The eco-risk index (RI) calculation showed that the value was 29 to 70 demonstrating a low class. The result also indicates that the accumulation of heavy metals investigated in this study was normal, and that the ecological risk was relatively low.

The problem of solid waste: origins, composition, disposal, recycling, and reusing

Solid waste disposal is a major challenge in many industrialized and developing nations, both in metropolitan regions as well as rural ones. The collection and disposal of municipal solid waste (MSW) is a serious issue facing metropolitan areas in many nations today. An effective MSW management strategy must satisfy all of these criteria: financial viability; technical feasibility; social and legal acceptability; and ecological friendliness. Small and large cities alike have a major difficulty in dealing with solid waste management. One of the current study topics is the valuation of food organic waste. Existing waste disposal methods include the typical landfill, incineration, composting, and other methods of handling solid waste. Composting and anaerobic digestion have traditionally been the most widely employed methods for the treatment and exploitation of the organic part of MSW (AD). The amount of organic solid waste (OSW) being generated globally is rising at an astronomical rate. Agricultural waste, domestic food waste, human and animal wastes, etc. comprise the majority of OSW. They're often used as animal feed, disposed of in landfills, or burnt. OAWs are made up of protein-, mineral-, and sugar-rich components that may be employed as substrates or raw materials in other processes.

Study of Potential of Marine Macroalgae Biochar for Acid Dyes Removal

The goal of this investigation was to check the feasibility of Ulva lactuca carbon could be used to adsorb acid yellow 19 dyes from an aqueous solution. A series of studies were carried out to determine the best conditions for acid dye adsorption. 90 percent colour removal was achieved when pH 3, 1 gm dose, 100 mg/L dye concentration were used for dye adsorption. During the analysis, it was discovered that as the carbon dose was raised, the dye elimination rate rose. The main objective of this study is to reduce solid waste disposal while also addressing the issue of seaweed and developing an effective plan

FORMATION OF MATHEMATICAL APPARATUS OF METHODS OF FIRE AND EXPLOSION SAFETY CONTROL OF LANDFILL

The authors analyze the fire and explosion hazards of solid waste disposal facilities, taking into account current trends in the introduction of biogas (methane) collection and utilization systems. Methane is considered an alternative energy source for power plants. The authors determined the initial and limiting conditions of the mathematical apparatus of the method of combating fire and explosion hazards of solid waste disposal facilities based on the results of analysis and synthesis of factors of occurrence and spread of man-caused danger, existing mathematical models, and methods of counteracting man-caused danger. This is the basis for the further development of appropriate emergency response techniques. During the analysis, the authors found that humidity, the temperature of the landfill (household waste), the presence of sufficient oxygen at some point in time initiate the formation of explosive concentrations of methane in the array and contribute to the spread of hazards in landfills or dumps. The specific weight of the organic component, the value of the density of the array, the height of the landfill affect the process of counteracting the danger, namely the prevention of dangerous events and prevention of emergency from the object to the highest level of distribution (local level), primarily in the first group priorities, such as the number of victims and injured civilians and specialists of the units of the State Emergency Service of Ukraine. The team of authors has defined a system of equations of connection of the existence of the mathematical device taking into account initial and boundary conditions. A system of communication equations is determined taking into account the initial and boundary conditions of the mathematical apparatus, which allows to further develop a control algorithm for emergency response related to fire and explosion hazardous landfills close to settlements.

The Health Effects of Chunga Dumpsite on surrounding communities in Lusaka, Zambia.

ABSTRACT Background: Dumpsites in low and middle income countries (LMICs) are commonly used for solid waste disposal as opposed to landfills. However, these are naturally unsanitary hence provide ideal conditions for breeding of disease transmitting agents and become predisposing factors for spread of diseases and infections to surrounding communities. This study aimed at determining the Health Effects of Chunga Dumpsite on surrounding communities in Lusaka, Zambia. Design and Methods: This was a mixed method design and employed a cross sectional approach and case study conducted concurrently. Communities were stratified by distance into Stratum One (within 250 meters radius) and Two (above 250 to 500 meters). Quantitative data were collected from total 200 households thus 100 households from each stratum by using self-administered questionnaires. Qualitative data were collected from Two Key informants from the Local Authority and 15 participants using semi-structured interview guide. Both data were collected from December 22nd, 2018 to February 18th, 2019. Results: Results revealed that smoke and various gasses emitted from burning and decomposing waste compromised quality of air in surrounding communities. Communities were infested with flies, mosquitoes and vermin. Consequently, (73.5%) complained of persistent coughing, (65.1%) suffered from malaria, (72.6%) complained of persistent headaches and (62.2%) had frequent diarrhoea cases in stratum one. Respiratory problems were more pronounced at night possibly due to high humidity which hindered pollutants to easily escape. However, these cases reduced drastically in stratum two. Conclusions: Unsanitary dumpsites in LMICs including Zambia are commonly used as solid waste disposal facilities as opposed to sanitary landfills and become predisposing factors for spread of diseases. Short proximities to dumpsites by unplanned human settlements cause serious environmental challenges leading to public health risks to surrounding communities.

Scenario of Municipal Waste Management in Malaysia

Malaysia has rapidly modernized, with most of the population now residing in cities and the remainder in rural or remote areas. The amount of municipal solid waste generated has increased in tandem with the country's rapid urbanization in response to that statement. Due to a lack of connectivity in rural areas, there may be insufficient infrastructure for a proper waste management system. As a result, illegal waste dumping was common, and landfills' massive volumes of waste may contribute to greenhouse gas emissions. The Malaysian government has responded by taking the necessary steps to upgrade the country's current waste management system in order to better manage municipal solid waste disposal. This research looks at how energy recovery from accumulated waste can be used as a renewable energy source, as well as the current issues, challenges, and proposed solutions. Methane gas produced as a byproduct of waste decomposition in landfills or disposal sites was used to generate electricity more efficiently and sustainably, resulting in a positive economic and environmental outcome.
