Recommended: Waste management in the Philippines brief intro

1. Introduction
Developing countries are characterized by rapid industrialization and a high population growth. As a result, the amount of generated organic wastes has increased. With the predominant methods of waste disposal, incineration and landfilling, there are problems associated. Incinerators produce flue gases containing bioaerosols, which cause environmental pollution. Though the use of landfills has been termed as efficient and to some extent environmentally friendly, most developing countries lack sufficient landfill capacities to handle the generated waste effectively. For example, according to the research conducted by Gautam, Baral and Herat (2009), when Gorkana, the largest landfill in Nepal got filled up, the waste management authorities started dumping wastes along the banks of River Bagmati. Conversion of organic wastes to biogas through anaerobic digestion offers the best solution to organic waste management (Zhang et al. 2014). Similar trend is seen in Malaysia where the landfills are almost reaching their life span due to improper management (Jereme 2013). This technology does not only provide disposal solution but also acts as an alternative to the existing sources of energy thus boosting the overall available energy for economic activities (Zhang et al. 2014).
The project investigates the health, environmental, cultural and economic impacts of anaerobic digestion in developing countries. The paper presents an overview of biogas production, biogas composition, biogas applications and finally the health, environmental, cultural, and economic impacts of biogas in developing countries.

...echnology does not only offer a solution to waste management but also acts as a substitute source of energy. Due to increased expenses on conventional biofuels, the need to reduce pollution and the ease of handling and disposing of organic wastes, biogas technology is widely employed nowadays.
Biogas technology has more positive impacts than negative ones in developing countries. It has reduced air pollution and improved hygienic conditions of developing countries. It has reduced environmental pollution by reducing the amount of carbon and its compounds in the atmosphere. Young girls have been empowered in society and education has been promoted. The technology has saved on costs by offering an alternative means of waste disposal and as a cheap source of energy. Finally, biogas technology has boosted agriculture by offering as an alternative to chemical fertilizers.

    In conclusion to this investigation one thing is clear and that is that recycling reeks benefits to the environment, Recycling material when compared to making material from raw material is a more efficient energy saving and more environmentally friendly way to reuse material that is usually consider as trash such as empty glass, and plastic bottles, or old newspapers. Recycling helps reduce the possible carbon emissions greatly and does reduce the human carbon footprint. But Recycling doesn’t resolve the pollution that is around the world today. Leading to new questions, questions like what about the landfills are they sustainable, and if so for how long. How long until the air becomes unbreathable? How long until Earth becomes its own furnace?

  • Importance Of Climate Change Essay

    1379 Words  | 3 Pages

    The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human

  • Biofuels Essay

    3324 Words  | 7 Pages

    Introduction:The idea of biofuels is a old concept, reaching as far as the ending of the 19th century. Solid in its idea but flawed in its presentation. Biofuels are a alternative energy to fossil fuels that are made from natural methods such as plants and crops and are key in solving the apparent flaws of fossil fuels. While fossil fuels have been in use for over a century, Biofuels have now risen to the popularity and been exposed to the press. At one point of time biofuel were being considered by some of the most brilliant minds ever in human history such as Henry Ford and Rudolph Diesel who believed that biofuels had the potential to be the new evolution s on only to reappear a century later. Now the world faces the struggles of global warming and the depletion of fossil fuels slowly dimming by day. Throughout the last century biofuels have proven to have a place in our society as a new alternative fuel source. Specializing in Being Natural and healthier than fossil fuels, biofuels have had a rough beginning against its competitor due to key situations such as pricing, Side effects, to fuel power. However the idea was passed on a to the later generations, and continued to pasand prolong usage. However through the last decade they have been highly advertised by politicians and Government officials claiming it to be the future of a powerful working society, and to help in making a new energy free world. Through belief Some even claiming that “By 2050, a new generation of sustainable biofuels could provide over a quarter of the world’s total transport fuel, according to a recent report by the International Energy Agency” (last name). With such improvement biofuels should be the obvious answer to providing a better future to th...

  • Biodiesel Essay

    548 Words  | 2 Pages

    Biodiesel is considered an environmentally friendly alternative because it reduces the amount many toxic substances. Plants such as soybeans require carbon dioxide from the air to produce their stems, roots and leaves. During biodiesel production from soybean oil, carbon dioxide is produced and released in the atmosphere. Carbon dioxide is considered a green house gas (GHG). However, this cycle of GHG emission does not neccersarily contribute to the atmospheric carbon dioxide levels. This is because the next soybean crop will reuse the carbon dioxide emitted for its growth. Another important environmental benefit is that biodiesel reduces particulate matter (PM), hydrocarbon (HC) and carbon monoxide (CO) emissions. These benefits occur because biodiesel contains 11% oxygen by weight. Oxygen allows the fuel to burn better, resulting in fewer emissions from unburned fuel. And lastly, biodiesel fuels do not contain any sulfur and does not have an unpleasant smell when it is emitted from vehicles.

He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.

  • Innovative Waste Disposal

    911 Words  | 2 Pages

    Traditional methods of waste disposal have proven to be ineffective and have caused harmful effects on the environment. The most popular and inexpensive way to get rid of garbage is burial, but burying your problems does not necessarily mean getting rid of them. Landfill sites pose as severe ecological threats as these mass garbage dump yards overflow with trash and frequently contaminate our air, soil and water with hazardous wastes. About 400 million tons of hazardous wastes are generated each year1. A large-scale release of these materials can cause thousands of deaths and may poison the environment for many years. For example many industrial companies around the world cannot afford to enforce the strict pollution regulations set by many developed countries. This usually forces these types of companies to move to developing countries where pollution regulations are very lenient. These developing countries knowingly accept environmentally hazardous companies usually because they are in desperate need of employment. The harmful effects of these companies were clearly illustrated in the 1960s and 1970s when residents living near Minamata Bay, Japan, developed nervous disorders, tremors, and paralysis in a mysterious epidemic. The root was later found to be a local industry that had released mercury, a highly toxic element, into Minamata Bay. The disaster had claimed the lives of 400 people1. Since 1970 you can bet that a lot more than 400 people have died as a result of waste disposal. If the type of waste disposal were cheaper and effective we wouldn’t have to deal with waste problems, which still plague mankind today.
