    Discuss The Extent To Which Sustainability Can Be Achieved

    Waste management is all about the need to change our attitude to waste. The four methods of managing waste at the moment are: landfill, composting, recycling and energy recovery (incineration). To be sustainable, waste must be managed in a way that is maintainable for the foreseeable future and will not be hurtful to the environment or the population. Waste is a problem at the moment because the amount of waste we use is increasing and therefore so is toxicity along with the time that the rubbish is toxic for. We are also running out of landfill sites. Therefore, another method of waste management must be found that will solve these problems.…

    Mass Wasting

    In our previous unit we learned about the rock cycle. Part of this cycle is the external processes we have come to know as weathering, mass wasting, and erosion. These processes occur near the surface of the Earth and are powered by the energy from the sun. In this essay I will talk about the process of mass wasting (Lutgens, Tarbuck, & Tasa, 2011).…

    mass wasting

    Mass Movement is defined as the down slope movement of rock and regolith near the Earth's surface mainly due to the force of gravity. Mass movements are an important part of the erosional process, as it moves material from higher elevations to lower elevations where transporting agents like streams and glaciers can then pick up the material and move it to even lower elevations. Mass movement processes are occurring continuously on all slopes; some act very slowly, others occur very suddenly, often with disastrous results. Any perceptible down slope movement of rock or regolith is often referred to in general terms as a landslide. Landslides, however, can be classified in a much more detailed way that reflects the mechanisms responsible for the movement and the velocity at which the movement occurs.…

    Water Waste

    Since all natural waterways contain bacteria and nutrients, almost any waste compounds introduced into such waterways will initiate biochemical reactions (such as shown above). Those biochemical reactions create what is measured in the laboratory as the Biochemical oxygen demand (BOD). Such chemicals are also liable to be broken down using strong oxidizing agents and these chemical reactions create what is measured in the laboratory as the Chemical oxygen demand (COD). Both the BOD and COD tests are a measure of the relative oxygen-depletion effect of a waste contaminant. Both have been widely adopted as a measure of pollution effect. The BOD test measures the oxygen demand of biodegradable pollutants whereas the COD test measures the oxygen demand of oxidizable pollutants.…

    Waste Management

    GROUP NUMBER 4 LEVEL 200 INDEX NUMBER: BIT/DP/09/10/1063 NAME: DANQUAH ASIAMAH EMMANUEL TERM PAPER TOPIC: WASTE MANAGEMENT IN ACCRA OR TEMA THESIS: The effective waste management can be done by public education on environmental cleanliness, enough dumping grounds for the waste generated, the practice of the polluter pays all, inspection of sanitary inspectors, reduction of waste of a firm or individual, re-used in the production process, recovery of waste, rendering harmless, Recycling of waste, disposed off, and the provision of resources needed to manage the waste. The waste challenge in Ghana leaves much to be desired. Its herculean nature has occupied the attention of successive governments, local authorities and international community. Ghana like all other third world countries is confronted with the challenge of municipal waste which is all over the place. These wastes include garbage, energy, water containers, food and everyday items such as products packaging, glass chippings, clothing, food scraps, furniture, bottles and newspapers. This threatens the environment as well as the health of ordinary people (Benneh et al. 1993). The problem of how to manage waste has been a problem especially in the big cities in Accra, Tema, Kumasi, Sekondi-Takoradi and Tamale. Waste management has been everyone’s business. Therefore, individuals, societies, and government must initiate these useful measures to prevent it effects. Public education on environmental cleanliness should be made available to all and sundry in order to create the necessary awareness. By this, the citizenry will know their responsibilities and contribute their quota to environmental management. This will help in managing waste in Ghana especially Accra or Tema. There should be enough dumping grounds for the waste generated to enhance their evacuation to the sites. The unavailability of such sites discourages waste management firms from carrying their assignment…

    Waste Water

    Water waste management is the field of handling waste water to make it suitable to either be recycled into a water system or to be disposed of in an environmentally-conscious manner. This is one of the larger problems facing most major cities in the modern world, with overflow causing severe pollution problems and increasing population densities stretching existing infrastructure to the breaking point. Both mechanical and biological processes are used to manage wastewater to get rid of undesirable particulate matter and to eliminate any potentially harmful pathogens.…
