Waste-to-energy

plants produce energy by first compressing U-235 uranium into small pellets and loaded into tubes. Dozens of these tubes are loaded into the core of the nuclear reactor. The core of the reactor is put into a steel tank filled with water to moderate the fission. They start fission by adding one extra neutron which causes the nucleus to split and releasing more neutrons, causing a chain reaction. The reaction heats the water, turning it into steam to turn turbines above. (“Nuclear Energy”) Nuclear power

How solid wastes have impact on climate change? The Earth’s atmosphere contains so many types of gases, such as water vapour, carbon dioxide, methane, nitrous oxide, and ozone and these are collectively known as “greenhouse gases.” Some of these gases occur naturally while others are result of human activities. The global temperature is regulated by these green house gases and is known as green house effect. The various human activities like burning fossil fuels and dumping solid waste, however,

Nuclear Energy as Alternative Energy As humans continue to generate more carbon emissions and other harmful gases to the atmosphere, climate change and global warming slowly happens. People have sought ways to reduce carbon emissions by switching to other sources that are both renewable and clean. Over the centuries, people were able to harness energy from other resources besides coal and petroleum. Alternative energy resources produce little to no carbon at all thus, reducing carbon emissions. Alternative

that 30 years from today our waste management system will be falling apart. By falling apart, I mean literally coming apart at the seams. There are at least 2,900 active Municipal Solid Waste (MSW) Landfills in the US which use Flexible Membrane Liners that average 1 leak per 1000 feet of seam. In addition, leaks can result from manufacturing and installation errors. An alarming fact is that there has been little to no research on the effects of chemicals and hazardous waste coming in contact with these

is transformed into another form of energy such as, mechanical or electrical. For a long time people have been using nuclear fission as an efficient and sustainable source of energy. However, the use of this form of energy is associated with a unique set of consequences including environmental, social and ethical. In this paper I will discuss nuclear energy and its impact on the environment. History of Nuclear Fission (Reactors) The discovery of nuclear energy goes back to 1980, when Henri Becquerel

of energy, like renewable energy resources. Solar energy, wind energy, different thermal and hydro sources of energy, biogas are all renewable energy resources. But, biogas is distinct from other renewable energies because of its characteristics of using, controlling and collecting organic wastes and at the same time producing fertilizer and water for use in agricultural irrigation. Biogas does not have any geographical limitations nor does it require advanced technology for producing energy, also

2.2 LANDFILL GAS GENERATION AND COLLECTION FROM WASTE Landfills are designed structures built into or on top of the ground to ensure refuse isolation. The design and operations act to ensure that there are minimal effects to public and environmental health. MSW landfills have 6 components: 1] Bottom liner systems, 2] Refuse wells 3] Storm-water drainage system, 4] Leachate collection systems, 5] methane collection systems, and 6] a covering cap. These components promote methane capture [Sawyer, 2007]

modern technology and science has played a significant role as measure to resolve energy crisis and global warming issues which resulted in life sustaining remedies and causes of mass destruction. However, many scientists agree that the earth’s fossil fuel supplies are dramatically depleting and this challenge will be a meaningful hurdle for future generations. Therefore, many countries may need to find new productive energy sources in order to tackle this problem. Many proponents of nuclear power suggest

alike, Nuclear energy has exploded, both figuratively and literally. Although in this case Nuclear energy is made for all ages. We all need energy and the solution of getting rid of nuclear power is not the long term solution. We want electricity and also safety at the maximum level. Nuclear power is one of the main go to energy sources when it comes to protecting our planet. It provides clean, safe and non toxic electricity. Other options that are trying to replace nuclear energy have the downsides
