INTRODUCTION OF ENVIRONMENT AND ENVIRONMENT ENGINEERING
Environmental engineering is the integration of sciences and engineering principles to improve the natural environment, to provide healthy water, air, and land for human habitation and for other organisms, and to clean up pollution sites. Environmental engineering can also be described as a branch of applied science and technology that addresses the issue of energy preservation, production asset and control of waste from human and animal activities. Furthermore, it is concerned with finding plausible solutions in the field of public health, such as waterborne diseases, implementing laws which promote adequate sanitation in urban, rural and recreational areas. It involves waste water management

RELATION BETWEEN ENVIRONMENT ENGINEERING AND CHEMICAL ENGINEERING
Chemical engineers have always been at the forefront of environmental protection. With a unique perspective that includes both science and engineering, they work in teams with other professionals. By designing complex solutions to our environmental challenges, chemical engineers are striving to save the world we live in. One success is the conversion of the sulfur oxides in power plant gases into gypsum for use in wallboard.
Environmental, Safety & Health
In almost every industry, chemical engineers are involved in areas that concern the environment, waste minimization, personal health and safety. The chemical engineer is employed to minimize the production of byproducts, if they are of no use, or find an appropriate use for them. Chemical engineers help minimize waste through process monitoring and control, and by designing new processes that are more

The honeycomb structure provides high catalyst surface area, which maximizes the contact between the catalysts and the pollutants in the hot exhaust gases.
It featured two distinct chemical engineering advantages:
It maximized the amount of catalyst-coated surface area to which the engine exhaust may be exposed, and
It minimized the amount of expensive precious-metal catalyst required.
Cleaner-burning fuels
Another way chemical engineers help reduce automotive air pollution is through advanced petroleum-refining techniques. One example is hydrotreatment, which uses hydrogen gas and a catalyst to produce gasoline and diesel fuel with significantly lower levels of sulfur and lead.
These techniques have made it possible to produce reformulated fuels that function as effectively as earlier leaded fuels, while releasing fewer pollutants
Reducing industrial air pollution
SO2 and NOx react with water to create acid gases, which in turn lead to acid rain. Acid rain damages cars and buildings, kills trees, destroys lakes and streams, and leads to
Some of the pollutants that GKN Aerospace produces stem from the use of solvents, degreasers, spraying of paints, spent fuel exhaust and chemical milling. GKN is aware of these pollutants and has taken steps to reduce the impact these pollutants have on both the environment and their workforce. One of the means they have taken is with the help of the State of Missouri Department of Natural Resources and the Occupational Safety and Health Association, also known as OSHA.
Catalytic converters have become a major importance in our world’s fight for global warming. Why? Because these catalytic converters are greatly reducing the amount of air pollution coming from the exhausts of our automobiles. “Two components of automobile exhausts that help form photochemical smog are nitrogen oxides and unburned hydrocarbons. In addition, automobile exhaust may contain considerable quantities of carbon monoxide” (Brown, LeMay, Bursten, Murphy, & Woodward, 2012). However, adding catalytic converters to the exhaust of automobiles will cause a chemical reaction to occur and help somewhat prevent the amount of pollution that exits the exhaust.
Chemistry is not used only in a lab environment, but it is used for every aspect of life. One way to look into a more in-depth view of chemistry is to apply it to a hobby, or something that may personally affect your everyday life. One of the biggest parts of my life and my main hobby is flying. Ever since I was little, I have always wanted to become a pilot. I am currently working towards my private pilot’s license and I am also attending the U.S. Air Force Academy starting in June to study aeronautical engineering. Since flying is such a large aspect of my life and is important to me, I wanted to break it down into an aspect of chemistry. I chose this topic because flying is very important to me and it will continue to be a large part of my life as it will end up being my career in the Air Force. Not only will researching the topic of aviation fuel help me to become a more knowledgeable pilot, but it will also help me to understand more about chemistry and expand on the concepts we have learned this semester. Chemistry is extremely important to planes and pilots. One of the most obvious aspects of flying that deals directly with chemistry is fuel. Without fuel, aircraft would not be able to run. The molecular formula of fuel and the combustion of fuel are just some parts that play into how fuel makes an aircraft run.
Chemists are the specialists in chemistry, that interact with chemical properties, and reactions. The earth is made up of different gases. Some of this gases are needed for life in the planet but other gases can be harmful to the living. Gas’s use in regular quantities are favorable to the earth. The world started to become more advance and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer.
Typical job duties include designing chemical plant equipment and devising processes for manufacturing chemicals and products. Applying principles and technology of chemistry, physics and engineering in everything they do. Chemical engineers design and plan the layout of equipment. They evaluate equipment and
The focus for future gasoline engine development will be on fuel economy improvements through improved combustion
Engineering is the cornerstone for human development. Engineers are problem solvers who search for quicker, better, cheaper, and more efficient ways to solve problems. Engineers use their knowledge in mathematics and natural sciences to produce and enhance modern technology. It combines different subsets of mathematics, science, and technology. The profession applies scientific theory to design, develop, and analyze technological solutions. It is generally accepted that the four major branches of engineering are mechanical, civil, chemical, and electrical. There are numerous other divisions derived from the concentrations, combinations, or extensions of the major
for the chemical engineer looks very promising. As new drugs and vaccines develop, the chemical
In today’s society, cars and other transportation vehicles produce pollution, harming the environment as well as one’s health. Engines produce toxic substances such as nitrogen oxides and sulfur dioxide. However, the invention of the catalytic converter has helped reduce the pollution. Catalytic converters were first used due to the contractions on toxic emission regulations in the 1970s. The catalytic converter “turn the harmful chemicals in vehicle exhausts into harmless gases such as steam” (Woodford). These catalytic converters are essential to creating a less polluted atmosphere. An engine with and without a catalytic converter differs greatly and the reactions occurring are very significant in understanding the role of the converter;
Chemicals are used in a wide variety of products and play an important role in the world economy. They are constituents of materials, are used in preparations and products and are embedded in complex physical systems. While chemicals are a significant contributor to national economies, sound chemical management across the life cycle - from extraction to disposal - is essential to avoid significant risks to human health and the environment, along with their associated economic costs, and to maximize benefits for human well-being. Growth in chemical production and use has slowed in many of the developed countries that previously dominated the market, while it has accelerated rapidly in a number of developing countries and countries with economies in transition. These countries are, increasingly, the drivers of global expansion in production and use of these chemicals.
Ever since I began studying science and mathematics at all levels of educations I have always had an interest in the production of useful materials. In the growing turmoil of today; a world full of global warming and diminishing resources, questions often arise in my mind such as, "can we make a more efficient, more durable and a renewable resource that will overshadow fossil fuels? and have less of an impact on our environment?" Up to now, I have not found a solution to these questions and answering these questions is a personal aspiration of mine which I aim to fulfil by achieving a degree in Chemical engineering and eventually I will contribute to the field in my own unique way. The debate surrounding sustainable energy fascinates me, having recently learned from personal research I have understood what an authoritative role chemists and chemical engineers play in the industry at the present time and how, by working as a team, they contribute to an improved future for the whole world. However, one of the main reasons that has single-mindedly driven me this far to want to study chemical engineering is a book I have read, “Beyond the Molecular Frontier: Challenges for Chemistry and Chemical Engineering” While reading this book, I had solidified my understandings of what chemical engineering is all about. Also, one of the main processes mentioned was polymerisation and is something I already study in A-level chemistry, it is something that not only interests me, but is a personal career aspiration of mine. Reading this book gave me a determination to be the person who helps improve the future of the industry and provide an answer to the questions I always ask myself by studying this degree.
...ree careers make sure that every day activities do not lead to the degradation of the environment. For these reasons, it is clear that chemistry is beneficial to the way of mankind.
Having a degree in chemistry opens the door to a wide array of careers. These jobs include chemical engineer, analytical chemist, and pharmacologist. The job that has me most interested is a Chemical Engineer. These top of the line engineers turn raw materials into useful products. They can make petrochemicals,
My father, being a chemical engineer, inspired in me an innate desire to be a chemical engineer myself. I appeared for the All India Engineering Entrance Exam (AIEEE) and was placed in the top 1% of the 1,100,000 students who had taken the exam. I chose Chemical Engineering as my undergraduate major at Visvesvaraya National Institute of Technology, Nagpur which provided me the opportunity to explore the breadth of chemical engineering. While the core courses provided the fundamentals of the field, the electives that I chose helped me gain an insight into the various facets of chemical engineering.
Environmental law is a broad form of law developed to regulate how human activities affect the physical and biological environment (Doremus et al 2008, 2). Environmental law can be large scale or small scale, global or local; but it takes the cooperation of many different agencies to be successful. Overall, environmental law has contributed to a healthier environment in many ways. Since the beginning of environmental law and regulation, society has seen advancements in sanitation, pollution, air and water quality disease control and prevention, and ultimately in quality of life.
