The differences between PC manufacturing and Green manufacturing
PC manufacturing:
Used in soldering of printed circuit boards lead can harmful for blood systems and kidneys.
Mercury: used in batteries, switches. Mercury spreads out in water transforming into methylated mercury that can cause chronic brain damage.
Cadmium: used in resistors for chips and in semiconductors. Cadmium is classified as toxic, these compounds accumulate in the human body, particularly the kidneys.
Green manufacturing:
Manufacturing of green computing includes:
Bamboo: is becoming increasingly popular for making casings for computers and

Conclusion:
Technology is not a passive observer, but it is an active contributor in achieving the goals of Green Computing. IT industry is putting efforts in all its sectors to achieve Green computing. Equipment recycling, reduction of paper usage, virtualization, cloud computing, power management, Green manufacturing are the key initiatives towards Green computing.
Current challenges to achieve Green Computing are enormous and the impact is on computing performance. Efforts of governments and non-governments organizations (NGOs) are also appreciate-able.
The greenest computer will not miraculously fall from the sky one day; it will be the product of years of improvements. The features of a green computer of tomorrow would be like: efficiency, manufacturing and materials, recyclability, server model, self-powering and other trends. References:

Lead is usually used in cell phone screens, circuit boards and the buttons.Lead is commonly used as a stabilizer in products and for pigment in paint, rubber, plastics, and ceramics. Lead's chemical properties also make it easy to use in metal products.
Arsenic is element 33 on the periodic table and is in Group 15. Arsenic is obviously an extremely poisonous element; however, some people have found arsenic to have a restorative effect on them. Chemically, arsenic is a metalloid. Two common forms of arsenic are gray and yellow. (see Figure 1-A) Element 33 has an atomic weight of 74.9216 and the chemical symbol of As. It boils at 613ºC, melts at 817ºC, and has a density of 5.72. (see Figure 2-A) The element has been known for centuries and can be easily obtained from ores such as arsenopyrite (FeAsS), realgar (As2S2), orpiment (As2S3), and arsenic trioxide (As2O3). There are many uses for arsenic. Among them is in the manufacturing of glass to eliminate the air bubbles and the green color caused by contaminated iron compounds. Arsenic is also added to materials such as lead and copper alloys to increase the strength and better the corrosion resistance. Although it is well known that arsenic is often used in tales (both true and otherwise) as a killing agent, arsenic has been used as a curative as well. Before penicillin was introduced, arsenic played a significant role in the treatment of syphilis. Other good uses for element 33 are as insecticides and semiconductors. Gallium arsenide (GaAs) is a known semiconductor that is also used as a laser material. A good test for the detection of arsenic is the Marsh test, invented by James Marsh, an English chemist.
There is a debate that there is not actually one person who discovered cadmium. In the year 1817, a physician named Friedrich Stromeyer was one of the first ones who discovered cadmium. There were two more people named K.S.L. Hermann and J.C.H. Roloff that also discovered cadmium the same year. Cadmium is a naturally occurring metal. Cadmium was first discovered in vapors that came out of furnaces. It was found because zinc oxide was being roasted. Some of the early signs of it were in paints. People would want to make light colored paint darker so they would add cadmium, which would cause a brighter color. The pigments were primarily made from cadmium sulfide. Cadmium was also used for making leather gloves darker (Dartmouth, 2010). Cadmium toxicity is when a person eats food that has high levels, breathes in high levels, or drinks water with high levels of cadmium. Short-term or long-term exposer can be harmful...
Unfortunately, PCBs are hazardous to human and animal health, as well as to the environment. In studies published by the Agency for Toxic Substances and Disease Registry (ATSDR), the following health concerns are related to the ingestion of PCB's in people:
Lead has become both a blessing and a curse to the population. It has provided us with many tools in order to help us live but it has caused lots of health related incidents. People who have been exposed to lead products within their environment risk the chance of having developmental problems along with causing organs within the body to become infected. Young children are especially vulnerable to the effects of lead because they absorb as much as 5 times more ingested lead than adults. They can suffer
Energy consumption represents a major sustainability issue for the ABC, because the provision of broadcasting and online services is energy intensive. Increases within the creation and distribution of content by the ABC has essentially needed the installation of latest computer servers and instrumentation, increasing the ABC’s energy needs. The ABC seeks to offset these increases with efficiencies in alternative areas, like the introduction of “virtualisation” software systems to scale back the impact of computer server hardware on energy consumption. Operational selections are guided by the ABC’s Environmental Management Policy (internal) and corporate Responsibility
The Macbook Pro Retina is one of the most popular technological products in the current market. The Macbook Pro is marketed as the greenest notebook by Apple but there are elements of the product that are not environmentally sound. This is proven with the study from the process from cradle to grave of the new Macbook Pro Retina. The environmental impact of the Macbook Pro can be measured by the lack of recyclability in the creation stage, the level of emissions in the transportation stage, the facilitation of disposal by Apple and local governments, and the economic viability of the MacBook Pro.
The second key point for Apple is renewable energy their goal was to achieve 100 percent of renewable energy which they have accomplished. In their data center in Maiden, North Carolina they have several approaches of energy efficient element designs. Two of their energy efficient designs were a chi...
Going green in the workplace is a new trend in business. In choosing to go green in the workplace you may be challenged by an elevated initial start-up costs, however savings earned from this investment will more than pay for those initial costs in the future. Many people see this as a controversial issue, and granted it does have its own unique set of pro and cons, but if a business makes careful choices going green can prove to be very rewarding. Companies are doing this to save money on energy expenses as well as deploying it as a means to help reduce the carbon foot-print they are leaving behind.
When every IT professional starts their journey into the IT Sector, they are bound to come across social issues which will have to be dealt with professionally. One important Issue is being green in Information Technology. The earth’s resources are continuously becoming scarce whilst the demand for them increases sharply. Every IT professional should understand that power consumption does not cover the whole green IT spectrum. Recycling dangerous electronic waste, optimising/virtualising servers to distribute workloads, having a long term green policy, reducing your workplace carbon foot print such as the paperless desk and an efficient data centre-business continuity model; these are a few examples of issues that professional must consider as these issues all occur in the green IT world.
At one time, lead poisoning was common among those who worked with lead, but such workplace hazards have been largely curtailed. Lead has been used by humans since ancient times. It was used in ancient Egypt in coins, weights, ornaments, utensils, ceramic glazes, and solder. Lead is mentioned in the Old Testament. The Romans conveyed drinking water in lead pipes, some of which are still in operation.
It is important to understand clearly what a Green Business is and what makes a Business Green (Friend et al, 2009 p.2):
Another important aspect of green architecture is the integration of energy efficient mechanical systems and conservation methods. Green buildings are designed to reduce or eliminate the dependence on fossil fuels. Additionally, green designs further help to minimize waste through the use of gray water recycling and other sustainable energy strategies. Grey water is conserved or saved to be recycled to water gardens.
