Materials Extraction

These batteries consist of heavy metals such as cadmium, mercury, zinc, and nickel, which are environmental pollutants. Hence recycling them instead of incinerating them together with household waste saves our environment. These valuable metals are recovered during the process of recycling and consequently, save energy by minimizing the use of raw materials. Several materials are extracted from the used batteries and are used to manufacture new ones. Manganese dioxide, which is normally used to catalyze the reaction that produces oxygen from hydrogen peroxide, is contained in the zinc carbon cell. Dry batteries also contain metallic zinc, which is usually ...

Questions over Case Study 11.1

Identify the weaknesses in each strategy. (Hint: How do you think the bond rating agencies reacted to California’s 2003 budget?)
The first dangerous strategy identified was -Delay maintenance and replacement of assets—and rely on hope (Starling, 2011). The weakness of this strategy is, in addition to posing a physical threat to the people who can be harmed by these delays, poses a very real threat to the budget. More specifically, Osborn an Hutchison (2004a) note that “avoidance becomes addictive, and the real problems fester and grow, ultimately requiring even more painful solutions (p.29)”
The second dangerous strategy ...

Structural Steel

Structural steels are the variety of steel customarily used for construction such as buildings, bridges and as reinforcements to concrete. It is used because of its strength and ductility (ability to deform substantially prior to failure). The form, shapes, and size of structural steels are dependent on the specific function that it will serve. There are several standards that must be followed when producing structural steels; these standards also include the specifications for the steel’s mechanical properties, chemical composition, specific cross section and shape profile (American Institute of Steel Construction np).
Structural steels have various chemical elements which ...

Alloy steels are basically carbon steels to which other metal alloys have been added so as to improve properties significantly. Three alloying compounds which are used in steel include manganese, chromium and nickel. The percentage of manganese present in steels ranges between 0.3% and 1.5%. It reduces effects of impurities gathered during the production process. It also works as a hardening agent, improves toughness and strength, non-magnetic properties and causes self-hardening to prevent abrasion. Chromium ranges between 0.3% and 4%. Its purpose is to improve wear, scaling resistance and oxidation. It also improves hardness and reduces ductility. Nickel ranges between ...

There has been increasing awareness of the role of waste in the production of greenhouse gas emissions and its impacts on climate change. Diminishing natural resources has led to the recognition that what is discarded as waste has the potential to be reused as resources. Governmental legislation on prohibiting toxic materials and prevention and control of the volume of waste has helped in decreasing adverse environmental effects. There is a growing public awareness about waste prevention and its beneficial effects. The society has to replace the linear model of extract-produce-consume-dispose to closed Loop's approach of resource recovery and waste ...

A fuel cell is a device that provides electrical energy. The cell is used to extract chemical energy from hydrogen gas and convert it to electrical energy. The fuel cell has two electrical terminals, an anode and a cathode, which supply electrical energy to an external electrical load. Inside the cell, hydrogen ions combine with oxygen to form water with the release of electrical energy. The hydrogen molecules are ionized to release electrons that travel through an external circuit thereby setting up an electrical current. The hydrogen ions are then reduced to water by reacting them with oxygen. A ...

Selling in Minnesota
Barbara Ehrenreich, the author of Nickel and Dimed, once more set her dreams on a fresh, idealized part of the country, Minnesota, where she hoped to get a slight more pleasant environment compared to her experience. However, Ehrenreich's hopes once again meet with a rough dosage of reality that she releases a defensive tone through a creep in her writing as if she has detected her enterprise is coming to existence: “If any enterprising journalist needs to experiment a low-wage form of life in the darkest Louisiana or Idaho, chief power to her. Name me gutless, ...

The increase in the average temperature of the earth's surface due to various greenhouse gases like Carbon dioxide emissions from deforestation or burning of fossil fuels due to which heat is trapped in the earth's atmosphere is called Global warming. Without this greenhouse effect, the heat would have escaped from earth's atmosphere. Micro-organisms that are found in the soil are very important for sustaining many ecological processes like nutrient cycling, the transformation of metals and decaying of plant matter. Soil micro-organisms contribute a lot to the consumption and production of greenhouse gases like methane, nitric oxide and Carbon dioxide ...
