Urban Waste Management

Solid wastes are those organic and inorganic waste materials produced by various activities of the society, which have lost their value to the first user. Improper disposal of solid wastes pollutes all the vital components of the living environment (i.e., air, land and water) at local and global levels. There has been a significant increase in MSW (municipal solid waste) generation in India in the last few decades. This is largely because of rapid population growth and economic development in the country. Due to rapid growth of urban population, as well as constraint in resources, the management of solid waste poses a difficult and complex problem for the society and its improper management gravely affects the public health and degrades environment. The population of Mumbai grew from around 8.2 million in 1981 to 12.3 million in 1991, registering a growth of around 49%. On the other hand, MSW generated in the city increased from 3200 ton per day to 5355 ton per day in the same period registering a growth of around 67% (CPCB 2000). This clearly indicates that the growth in MSW in our urban centers has outpaced the population growth in recent years. This trend can be ascribed to our changing lifestyles, food habits, and change in living standards.

Waste referred as rubbish, trash, garbage, or junk is unwanted or unusable material.
According to European councils’ directive “Waste is any substance or object which the holder discards or intends or is required to discard." Waste if it is hazardous or toxic, it could even be a harbinger of disease and death, not just for living beings, but for all that sustains life, for example, water, air, soil and food.

Solid waste can be defined as any solid or semi-solid substance or object resulting from human or animal activities, discarded as useless or unwanted. It is an extremely mixed mass of

The Great Pacific Garbage Patch

...The Great Pacific Garbage Patch This article is about the trash that ends up in the oceans and builds up into a giant garbage patch. When people throw their garbage on the ground it ends up in a small body of water and eventually travels into the ocean and gets stuck in this unbelievably large collection of trash. I think it is terrible when people litter because that litter ends up in the oceans and can hurt many animals. This problem is very serious and needs to be looked at as a bigger problem. Even though there are a lot of other problems going on in the world today, this is a big one that is affecting harmless animals all over. Plastic bags are mistaken for jellyfish, bottle caps are also, and are fed to baby birds. This is proven when birds die and left inside the body are tons of bottle caps and broken down plastic. I think this problem can be solved or at least made a little better. One possible solution is to ban plastic bags so people use the reusable ones. They could also make recycling a law. I am not sure how much can be done of what is already in the garbage patch, but we can try to keep it from getting worse. Because the water flows so far, there could always be places set up to pick up garbage that was missed earlier. This garbage patch is out of control and is only going to get worse, unless we decide to do something about it. It hurts animals, our water and will eventually hurt...

...is a moral issue because some people just do not care how much electricity they waist or that by using certain products they could save our planet from pollution. Pollution is another issue that is big concern in our world today. The community where I live has a chemical plant not far from it and over the years there have been many struggles to get them to dispose of their wastes properly. This is our world and if we do not take care of it by conserving energy and limiting pollution what will it be like for our children and grand children? Will there even be a world? Will there be diseases worse than cancer? These issues I believe are more of moral issue than anything else and it all comes down to respecting others as well as our homes and environments. To solve these issues I believe that there should be training available in the schools, work places and communities. Factories that have chemicals or cause any other kind of pollution should be punished for not obeying the laws and regulations on dumping wastes. Every employee should be made to take part in training for how to properly expose of waste without polluting our environment. I mean every employee that works for them. By providing training to them all then if they heard or seen something done wrong they could help resolve it. To help with using less energy, I believe some of the products on the market are way too expensive for the average household so they should be made less...

...Carry reusable shopping bags at least some of the time, and save on plastic and paper bags. Waste less. There are hundreds of opportunities to nurture a zero waste culture. Use both sides of a paper, carry your own mugs to coffee shops and bring your own bags when you go shopping, or get printer cartridges refilled instead of replacing them. Compost food scraps, avoid bottled water and other packaged products, upgrade computers rather than buying new ones... the list is endless! Reduce, Reuse and Recycle. Make it a habit to reduce the things we need or we consume. Purchase only things that we only need and eat only what you can. Let us do our share not to be part of the problem or should I say part of the garbage problem. Reuse all the things that can still be repaired/fixed or those things that are still okay. Recycle things to conserve our resources, collect old newspapers, books, magazines, used papers, bottles (plastic and glass), and any other things that you could sell in junkyards. There is money in garbage and at the same time we’re doing our part in recycling process.  Be responsible with your garbage, dispose them properly. Also try to use segregation scheme with your trashes, separate those decomposable from those that are not. You may utilize a compost pit to house all of your organic trashes and eventually use this as your fertilizer for your backyard garden or to your plants.

Environment Pollution

...How to Prevent Pollution “This entire planet is our home. We are the only species that systematically destroy our own habitat."- Marianne Williamson Pollution prevention is an exceptionally major global concern because of the harmful effects of pollution on the person’s health and on the environment. Environmental pollution comes in various forms, such as: air pollution, water pollution, soil pollution, etc. Everyone is a stakeholder as we are all inhabitants of this one and only mother earth. Each person has something to contribute to advance an effective pollution prevention awareness initiative. Environmental protection is caring for us, loving our children and ensuring a sustainable future for generations to come. "If we heal the earth, we heal ourselves." You and I should therefore accept personal responsibility for the success of the environmental protection programs of our respective community by cooperating and actively participating in making the atmosphere pollution free. Help stop pollution today. Although on an individual basis we can help combat pollution in our own immediate environment, efficient control can be best institutionalized through legislation. Thus, most countries have already addressed the issue by passing some form of pollution prevention measures. Averting the onset of pollution in any area, i.e. be it on air, water or land, could be the start and the simplest preventive solution to the problem. This calls for a conscientious effort to adopt...

Fenugreek Facility Management Report

...FENUGREEK RESEARCH COMPANY LTD. FACILITY MANAGEMENT REPORT EXECUTIVE SUMMARY This ten-page facility assessment report presents the findings from a three-week period of investigation in Fenugreek Research Company Ltd and relates recommendations both operationally and strategically which the Fenugreek management is advised to take to resolve the issues that surfaced during the period of investigation. Seven most pressing concerns coming from the Fenugreek staff were each dealt with in detail and suggestions for them were subsequently discussed for its feasibility. The findings of the investigation brought this Facility Manager to the conclusion that there is general dissatisfaction with the current working conditions of Fenugreek Research Company, which must be addressed individually in face of a period of uncertainty and change as the company owners look to float the firm and make it a public concern. The recommendations presented were judged for their practicability and immediacy of solution to the pressing concerns of the Fenugreek employees. INTRODUCTION Although facility management has long been practised by military, government and schools, it is a fairly new business and management discipline. As the role of the physical work environment on performance and productivity started to become more and more evident in studies, so has the field become more and more involved in a business context. In a compilation of over 40 studies of productivity improvement, changes in performance...

Environmental Racism

...Racism 2 In this current disenchanted world, there is no meaningful order of things or events outside the human domain. When the forests and the farms are no longer considered sacred and the spirits we tempted with food and sacrifice have no mysterious risks associated with the systematic rape of mother Earth. Then a disenchanted nature is no longer alive. The living Earth commands no respect, reverence or love. It is nothing but a giant machine, to be mastered to serve human purposes. The animists(1) took care of this planet on up to the last few hundred years. As man accidentally discovers the beginnings of commerce that opens the doors to an industrial nation, then an industrial world will soon discover industrial waste. Whether the notion that a mountain or a tree is to be regarded as a person is taken literally or not, the attempt to engage with the surrounding world as if it consists of other people might possibly provide the basis for a respectful attitude towards living things. If your disenchantment is over the environmental problems and destruction, then the environmental racism byproduct can be regarded as an attempt to reveal to you that we are part of the world collective and that we are in a sense, the world itself. Environmental racism(2) is one of the biggest problems the world faces today. Issues created by corporate polluters produce trouble in the form of economic, as well as, physical. For some individuals and cultures, it affects them every...

...irrigation, human consumption, as well as livestock consumption. Since water is a flow resource, it is affected by activities that have nothing to do with it. For example, a small feedlot may be on top of a hill, when the livestock waste runs to lower ground, it runs in the nearby canal, which then empties into the creek will affect neighboring water tables. This can contaminate the drinking water in the wells. The Federal government has imposed regulations of waste water through the Department of Environment Quality. Early in our history, America was quite delinquent with our management of waste. Perhaps the land seemed vast and lack of scientific knowledge led to poor waste management. Because of these practices, many drinking water sources were contaminated with harmful toxins. The Love Canal was a catalyst that got the federal government involved. “Though the federal government had established a long history of oversight of water resources…it was not until 1965 that the federal government finally put the solid waste problem on par with protection of water resources” (Roberts, 2011, sec. 1978-1980). State regulating agencies such my home state, Oregon Department of Environmental Quality, have the latitude to regulate how citizens put in their waste systems. It is easier for state agencies to have a better idea of managing these guidelines since onsite visits would nearly be impossible if the...

Wal Mart Japan Case

...Japanese tends to prefer quality over low prices, which constrasts with Walmart core value as Wal mart's motto is Every Day Low Price. Also, Japan is a small country with limited spaces, which has several implications for Walmart. Small housings and apartment sizes, with high rent prices means that Japanese would need to minimize their purchases. Japanese are having trouble with lack of storage room to store purchases. For example, a typical apartment in Japan would be 1 room apartment with Living, Dining, and Kitchen area. A normal size of Japanese apartment are an average of only 27,55 sqm. Japanses likes to make several small purchases frequently. They minimize purchases, they would make their purchases several times a week, in small quantities. This means that stores would have to be readily available within reasonable distance, and bulk purchasing is discouraged. Compared to Walmart usual practice of centralized, big stores, with bulk purchasing to save costs, a neighborhood convenience store would be more suitable for the Japanese people. Japanese have high operating costs, especially because of the prices of rent and buildings in general. An average commercial land prices in Japan is 156,857 Yen (USD 2,017)/sqm, with average commercial land price in Tokyo reaching 1,551,400 Yen (USD 19,956)/sqm, followed by Osaka with average commercial land price of 493,700 Yen (USD 6,360)/sqm.

Man Versus Nature: Technology Versus Environment: Money Versus Wild Life

...Man versus Nature: Technology Versus Environment: Money Versus Wild Life Bristol Bay Although the fishing industry has long been associated with the contribution of marine pollution little work has been done on the effects on the industry itself of marine debris and other pollution. The fishing industry is responsible for discarded nets, hooks, fishing poles, and many times sunken boats, among other gear. In many circumstances this is not the intended plan when going fishing to catch their paychecks. In fact the fishing industry pays a high price for these losses from the time they have to replace their nets to the pulling of old nets and trash out of their new nets on a regular basis. When questioned about the effects of marine debris on their fishing activities, Shetland fishermen responded that 92% had recurring problems with accumulated debris in nets, 69% had had their catch contaminated by debris and 92% had snagged their nets on debris on the seabed. Many also experienced fouled propellers and blocked intake pipes. On average, 1-2 hours per week were spent clearing debris from nets. Debris could cause a restricted catch and many boats avoided particular fishing areas altogether due to the high concentrations of debris. It has gotten to the point for many fishers that they can no longer fish certain areas known to be well stocked with money fish due to the time consuming issues with trash and fishing debris in those specific waters due to left behind gear.
