...of waste for energy production becomes increasingly interesting both from a waste management perspective - to deal with increasing waste amounts while reducing the amount of waste deposited at landfills and from an energy system perspective to improve the flexibility of the energy system in order to increase the share of renewable energy and reduce greenhouse gas emissions. The object of analysis is waste which is not reused or recycled, but can be used for energy production. Different Waste-to-Energy technologies are analyzed through energy system analysis of the current Danish energy system with 13-14% renewable energy, as well as possible future Danish energy systems with 43% (2025) and 100% renewable energy (2050), respectively. The technologies include combustion, thermal gasification, anaerobic digestion, fermentation, and transesterification technologies producing electricity, heat, or transport fuel. In the USA, according to the US energy recovery council, there are 87 WTE plants producing 2,700 megawatts that results into 17 million of kwh per year which is enough to meet the needs for power for 2 million households. In the EU incineration is more popular. According to the confederation of European Waste to energy plants (CEWEP) the plants in Europe can supply annually about 13 million inhabitants with electricity and 12 million inhabitants with heat. Waste to energy is produced mainly by biological material and thus the energy produced is mainly biomass energy along...

...GASTO ENERGETICO Introducción La Carga de Trabajo es "el conjunto de requerimientos psicofísicos a los que el trabajador se ve sometido a lo largo de la jornada laboral". Para realizar una valoración correcta de dicha carga o actividad del individuo frente a la tarea hay que valorar los dos aspectos, él aspecto físico y el aspecto mental dado que ambos coexisten, en proporción variable, en cualquier tarea. En general, gracias al progreso técnico implica un crecimiento de los requerimientos mentales en detrimento de los físicos en muchos puestos de trabajo, no es menos cierto que aún existen puestos en los que las exigencias físicas siguen siendo elevadas, por lo que es necesario evaluarlas y aportar las medidas correctivas para eliminar en lo posible los trabajos pesados que a la larga sean dañinos para el trabajador, y en ultimas para la productividad de la empresa. En esta parte del curso se pretende analizar y comparar diferentes métodos para determinar el gasto energético en una tarea, es decir, se centra en el componente físico del trabajo. Marco Teórico La sangre es el fluido que circula por todo el organismo a través del sistema circulatorio, formado por el corazón y un sistema de tubos o vasos, los vasos sanguíneos.

...Waste and Energy Paper Name ENV 100 April 11, 2011 Tamue L. Gibson, M.S. Waste and Energy Paper Pollution introduces contaminants or pollutants into the natural environment that causes unsteadiness and long-term effects to the ecosystem. Waste is slowly polluting the environment and killing humans, plant life, and animals. Waste comes in many forms: solid waste; plastic, hazardous waste material; nuclear waste, and fossil fuel; oil. The world has become a gigantic trashcan. With the expansion of technology, humans are gutting out the earth’s resources, the results are creating an imbalance in the climate, and millions are suffering from ill health. Biological diversity in parts of the world has become an important issue of discussion to environmental activist. Recommendations for illuminating waste are concerns of nations worldwide. Alternative solutions will make way for improvement to the environment and health for millions of people. Plastic bottles are washing ashore on beaches and polluting the oceans. Plastic bottles are the largest source of pollution (Plastic Pollution Collation, 2010). Such items as plastic utensils, straws, lids, and bottles are releasing chemicals into the ocean and destroying the marine life beneath. Although designed for temporary use, they remain around forever. The American Chemical Society studied water samples and found polystyrene, a commonly used plastic found in cutlery and Styrofoam, and went on to say that plastic is a new source...

...Waste and Energy Paper Team A ENV 100 February 13, 2012 Instructor - Onesimus Otieno Waste and Energy Paper Oil is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. Oil is then refined and separated into different products – such as gases, jet fuel, heating oil, diesel, and asphalt. Oil is also used to make petrochemicals, compounds used to make products such as fertilizers, plastics, paints, pesticides, medicines, and synthetic fibers (Berg & Hager, 2009). Most environmental problems associated with oil are caused by burning and transporting it. Burning oil produces carbon dioxide, which is a greenhouse gas, so it contributes to global warming. It can also lead to acid deposition because the combustion of oil is the leading cause of nitrogen oxides. Nitrogen oxides inhibit plant growth and they are involved in photochemical smog and acid deposition (Berg & Hager, 2009). They can also lead to acidification of soils, affecting the plant varieties that are able to grow in the soil. This leads to a decrease of diversity in the environment. Plants that cannot handle acidic soils die off. In turn, animal species in the area decrease as only the species that can live off of those particular plants will thrive. Others will move on to new areas looking for plants that they have become accustomed to. Another...

...of large amount of waste, then identify different ways to reducing the amount of waste people produce. By Latchaya Paknam Earth is confronting with many environmental crises, for instance global warming, overpopulation, resources depletion, energy and pollution. Luis F. diaz (2011) points out “These crises are interrelated and connected to waste and waste management”. World bank (2012) states that “Currently, world cities generate about 1.3 billion tonnes of solid waste per year. This volume is expected to increase to 2.2 billion tonnes by 2025.” Large amount of waste generated leads to serious problems. The world immediately needs effective sustainable methods to tackle this problem for our next generation. Firstly, this essay will examine 3main impacts of waste disposal and then will provide effective solutions based on this examine. Waste is not always a broken or expiration but waste is unwanted or un-useful material that human throws away. Waste disposal causes enormous environmental impacts. The first impact is Environmental impact. Waste creation drains a large number of natural resources. Giljum et al.,(2008),cited in Zaman, Lehmann 2013,p.124) state that a great deal of natural resources are consumed daily. 120-130 billion tonnes of those raw materials are used for news products and generate approximately 3.4 to billion tonnes of municipal solid waste every year. Energy is one of the resources significantly depleted by deposing waste. According to Zaman...

...WADING THROUGH THE WASTE: A LOOK INTO THE FAILURE Wading Through the Waste: A look into the failure of American landfills and how plasma gasification can fix it Joshua A. Valdez ITT-Tech Jacksonville, Fl GE117 Chambers Abstract America, a “throw away” society, is facing a tragic consequence of its lifestyle. Even with increased recycling efforts Americans are running out of space to put their trash. With stricter regulations and public policies, the number of landfills has significantly dropped; replaced by what are called “megafills.” Although safer, since the EPA’s introduction of strict regulations in 1988, environmental dangers still exist. That danger, amplified with the high operation costs of landfills, an alternative disposal method is needed. Plasma Gasification provides a cleaner and more efficient way of disposing waste while having the added benefit of producing energy. Wading Through the Waste: A look into the failure of American landfills and how plasma gasification can fix it “Did you know that the average person produces three pounds of trash a day? I would really like to know where it all goes,” a woman asks her therapist in the 1989 movie Sex, Lies, and Videotapes. Since 1989 our trash production has increased to 4.6 pounds per individual, based on a 2007 EPA study. (EPA, 2012) America, a “throw away” society, is facing a tragic consequence of its lifestyle. Even with increased recycling efforts, Americans are running out of space...

...ENVIRONMENTAL CHALLENGES IN NORTHERN NIGERIA: THE WAY FORWARD A position paper submitted to Northern Delegates at the National Conference Abuja By Yusuf Abdullahi Rigasa (PhD) yusuf.rigasa@gmail.com An Associate Chief Lecturer at the Department of Environmental Science Kaduna Polytechnic, currently on secondment to National Oil Spill Detection and Response Agency, NOSDRA, Federal Ministry of Environment Abuja. 2014 Introduction Northern Nigeria was a British protectorate which lasted from 1900 until 1914 and covered the northern part of what is now Nigeria. The protectorate spanned 255,000 miles (410,000 km) and included the states of the Sokoto Caliphate and the Kano emirate and parts of the former Bornu Empire, conquered in 1902. The protectorate was ended in 1914, when it was unified with Southern Nigerian Protectorate and Lagos Colony, to become Northern Province of the colony and protectorate of Nigeria or the Northern region. The Northern Region was one of Nigeria's federating units. It was created before independence in 1960, with its capital at Kaduna. In 1962, it acquired the territory of the British Northern Cameroons, who voted to become part of Nigeria. In 1967 the region was split into states - Benue-Plateau State, Kano State, Kwara State, North-Central State, North-Eastern State and North-Western State. Currently, the region comprises of 19 states and Federal Capital Territory Abuja. The climatic conditions in the northern part of Nigeria exhibit...

...attached at the center, which helps for a faster combustion process and also prevents incomplete combustion. The ash and the residue thus generated due to the combustion is forced at the periphery by this rotating shaft. The ash is pushed into an ash hopper and it gets collected there. A door is provided to dump the waste inside the incinerator. This door pneumatically operated and when opened shuts down the fan and the burner automatically. Not all the ash gets collected in the ash hopper. Some of the ash due to the forced air goes up to the chimney with the smoke. To remove this ash from the smoke a char eliminator is used. A char eliminator is similar to a filter paper. A sight glass is provided at the side of the incinerator to keep a watch at the burning process. All the processes are controlled with the help of a control panel that is fitted on or near the incinerator. Working and disposing Solid waste is put inside the incinerator through the waste door, in properly arranged stacks so that the chances of incomplete combustion are minimized. The oily sludge or waste oil is not directly put into the combustion chamber neither it is put through the waste door. A...

Reference……………………………………………………………………….page 7 1. INTRODUCTION Why is more environments destroyed in the 20 century & 21 century than before? Primarily, industrial revolution had turned hand-made into mechanization. The machine required energy to work. To get energy, people continuous depleted energy sources such as forest, and coal mine which need ten thousand years to generate. Consequently, this actions lead to a malignancy which environment is destroyed. I learned that in the nineteenth century, River Thames had a crisis. Because of the industrial revolution, factories littered the chemical materials in the river. Also as populations in London city grew, the amount of waste it produced expanded exponentially. British government didn’t recognize how serious it is, and there were no law to permit this action. For centuries, various wastes that came from human, animal, and industrial polluted England’s most famous river. Also River Thames had long been using as a water source even the water was polluted. River Thames had directly affected resident’s life. It brought diseases that caused...
