The Importance Of Contextual Understanding For Engineering Practice

This was the motivating factor in my decision to pursue civil engineering in one of the premier universities of my country, namely Gitam University. As I started my coursework and explored the world of Civil Engineering, I surprisingly found it to be much more challenging and understood that it requires a multidimensional approach.

Identified wastes in the current processes using the seven wastes as a guide to what should be looked for. The question was asked, “Why did this waste occur?” and, “What can be done to prevent it?”.

The waste problem in our world has become atrocious. As explained in “A Dirty Dilema” by Zada Lipman, waste from factories is being dumped in rivers, lakes, and open areas with no one around it. In “The Truth About Recycling” written by Leo Hickman, it explains how waste is being checked for quality and how people are losing confidence about recycling. For my last article, "Recycling Rare-Earth-Metal Waste Using Hydrometallurgical Methods." by E. G. Polyakov and A. S. Sibilev, they explain how metals can be recycled for better use or better storage. Our environment is slowly being destroyed because of how we get rid of waste, but we are able to fix this problem.

If your waste could be useful to someone in need, make sure they get it even if it means an inconvenient trip to drop it off. Make the effort to ensure that what you consume or what you choose to dispose of is shown the respect it deserves as a product of a real person’s hard work.

A garbage crisis is at hand. As a nation, we have begun to worry that the growing mounds of wastes will only continue to increase as the means of disposal become further restricted. Government agencies and public officials are urgently trying to find a solution. The waste dilemma has become the centerpiece of the

The challenge taken on by EWB in Zambia with the assistance of the UNHCR, (the United Nations refugee agency) is focused on the Mayukwayukwa refugee settlement in the Kaoma District of Zambia’s Western Province. This settlement houses over eleven thousand refugees, most of which have been displaced due to the war of liberation in Angola. Other refugees in the settlement come from the Democratic Republic of Congo, Burundi and Rwanda. (UNHCR Zambia | EWB Challenge, 2016). EWB has taken the challenge of developing engineering and technological solutions to assist the integration and creation of sustainable livelihoods for the refugees thanks to pledges by the Government of the Republic of Zambia in 2011 and 2013

As has been asserted in a lot of research, how to handle human waste could be a major issue. Human waste including food waste and body waste. The human body waste will be focused in this report. According to GENECO, there are 75 million m3 of human sewage have been creating every year in Bristol. The human body waste could contaminate water system and lead disease if they haven 't been treat appropriately. As Tearfund and WaterAid(2002) has pointed out, four out of ten people, 2.4 billion, are suffering from the disease caused by the issue of poor sanitation. Therefore, action on sanitation and re-think how to use the human body waste will make work more effective. In order to address the research question ‘is it possible that human body waste could be use as renewable energy ', the technology of composting human body waste will be investigated, data and case study will be analyzed in terms of energy consumption, water use and air pollution, finally, how to make human body waste as a useful substance and achieve sustainable lifestyle will be answer.

The average resident produces seven and a half pounds of garbage every day that is buried down in landfills and litters lands costing a great amount of money. Nowadays, people face no more critical trouble than the need to save the weakening environment, mainly in urban areas, where solid wastes are uselessly dumped. It has been observed that cities have no controlled structure for garbage disposal. Each year, millions of dollars are spent picking up litter and more is thrown away in valuable materials that could be recycled. As humanity develops new technology and equipment, the level of waste increases every day. Due to the fact that there is a huge problem with garbage disposal, government representatives must contribute to resolving

A.O. Coaker ,C.G.Achi, M.K.C. Sridhor, C.J.Donnett(2015) studied the current institutional solid waste management in a Nigerian private institution of higher learning. Using key informant as interview and personal field observations, the waste generation rate, pattern and characterization was made. It was concluded that if all the organic waste streams from the kitchens ,canteens and animal house are utilized for the bioenergy and organic fertilizer and non-biodegradables can be sold in the secondary market and considerable amount of wealth can be recovered

Out of all the growing problems in the world, the massive accumulation of garbage seems to be the least of the people’s worries. Countless landfills are being satiated by trash of all shapes, sizes and composition; many now being paved over to serve as foundation for housing, airports, businesses, etc. If the situation were as simple to resolve as paving over the putrescent landfills, then there wouldn’t be debates or research about the environmental effects of pollution associated with improper discarding of waste materials. A majority of the types of waste can be recycled, but at what cost? Many will argue that recycling is the only way to eliminate such landfills and protect the environment from further damage. Several

We, humans, are producing waste every day, polluting and destroying our planet. To save the world, many people believe recycling is the obvious solution. It is the process of converting certain waste into a reusable material. Therefore, the recycle motto is “Reduce, Reuse, and Recycle”. However, have you ever wondered why the word recycle is placed at the end? Well, it’s because it is not the only way to reduce waste and save the world from global warming. Recycling may have many advantages, but its disadvantages’ list is not a short one either. Recycling may look very simple and easy method, but when there is a need for a new unit of waste recycling, it takes up a lot of space. Not to mention the amount of money the building costs along with paying the staffs, buying new utility vehicles, upgrading the recycling unit and different types of chemical disposals. It is not only expensive but also, unhygienic, unsafe and unsightly with piles of waste materials on every location. These wastes spread infectious diseases putting human health at risk. Aside from recycling

Proper waste disposal reduces the impact of waste into the atmosphere by observing the proper methods of disposing. Because improper disposal of our wastes imposes cost on others, waste disposal has been a big political issue. Dirty disposal methods such as dumping are big problems nowadays. Though the easiest among any method, it creates health risks for the public. Waste disposal was not always observed and monitored properly; therefore, everyone must comply with the methods used in order to achieve environmental advantages. Achieving this awareness in proper waste disposal is important to lessen the waste we dispose improperly.

Waste management applies to a variety of resources, from food to energy to water. Nature itself produces no waste,

The first is to manufacture recyclable products from the waste plastic that cannot be sold to recycling factories. The second is the development of a calendering machine to improve the efficiency of the Cartoneros. Social, environmental and economic constraints must be considered with regards to the waste problem to ensure that the final solution, is not only appropriate to the context, but is also useful for the residents, cheap to produce and not harmful for the environment.
