Transcript: E-Waste Presented by PERSON for COMPANY About What is E-Waste E-Waste is the process of getting rid of your electronic devices. These devices can be phones, computers, Televsions, printers and scanners. Digitally responsible Why should we be Digitally Responsibe? Stats Statistics We generate around 40 million tons of electronic waste every year. Only 12.5% of E-Waste is recycled. 80% of E-Waste in the US and most of other countries are transported to Asia. MAP MAP CHART CHART What does it mean to be digitally responsible Digital Being digitally responsible means to have the right to privacy and freedom to any digital devices. It is the action of disposing of your electronics in a safe way. Why should we be digitally Responsible? why? We should be digitally responsible because it keeps the environment clean and sustainable. If we dispose of our electric devices in the correct way than toxic gases won't be released into the air and cause sicknesses. Being digitally repsonsible creates a safer workspace online and prevents any online problems. How Can we be Digitally Responsible? how? In order to be digitally resposnible we need to respect the right of privacy and freedom in personal expression online .Once we are done with our devices, instead of shipping them off to a country illegally, you can either hand them into your nearest recycler or resuse old batteries.

Transcript: E-waste presentation E-Waste E-Waste E-Waste is the rejection and abandoning of Electronic devices and machines that are still able to be salvaged. Things such as phones, TVs and electronic toys make up most of this percentage. Recent discovery has said that only 12% of current e waste is being recycled and e waste sent to landfill equals about 70% of overall toxic waste. According to another survey in America, Americans dump phones containing $60 million dollars worth of gold per year. The subjects that will be discussed are effects on the environment, the waste of reusable minerals and metals. Issues of E-Waste Issues of E waste E-Waste has a lot of issues connected to it, but some of the biggest issues of E waste are its affects on the environment, the amount of people wasting and the amount of waste of reusable minerals and metals. E waste is a very harmful thing when it comes to the environment, and it can sometimes lead to death. Most electronics include zinc and copper which are hazardous to the environment and if it gets into the water stream and is ingested, it can affect the kidneys really badly. another effect is that since most e waste has gold and silver and other expensive minerals. if the amount of e waste per year is taken into account, there is a lot of gold being wasted. Why E Waste is an issue Why it should be dealt with E Waste is a really big issue for not only the environment, but for us humans too as there are many dangerous chemicals and materials in electronics, like led, mercury, glass and chromium, that can be harmful to our health. it is especially dangerous in third world countries were most e waste is thrown into a pile and burnt, sending poisonous fumes into the air and endangering the lives of the children and adults living there. Solutions for E-Waste. Solutions There are many different ways we can prevent E-Waste and its problems. Lots of people and companies have already started on decrease the amount of e waste being produced. An example of this would be companies like Telstra, which have set up electronic waste and broken electronics bins at most if there shops, which is supposedly sent to a recycling site. Another company has taken e waste and put it in a machine that separates all the different components of the electronic, and they use the plastic to make 3 d printed objects like limbs, and then extract the valuable materials like carbon fiber or gold and silver. This amazing machine was created b Prof. Veena Sahajwalla. The best Solution The best solution Though there are lots of great and convenient ideas for solving E-Waste, the best and most practical one would be Professor. Veena Sahajwalla's "Mini Factory" invention. This small machine separates the individual items by using a small but concentrated laser at the object, which creates a small explosions that has separated all the materials apart. the metals, glass, and the small coding boards. this invention turns the plastic into ammo for a 3D printer that prints things like prosthetic limbs.

This is because if the same organism enters the body, the immune cells will recognize it and will make an efficient resistance against it.The pros of vaccinations are: It can wipe out diseases and prevent them very well. Taking the measles vaccination makes you 35x less likely to contract the virus You only have to have the vaccinations once, although sometimes you have to have boosters that keep the level of the drug up in your body. Pros of antibiotics Unlike antibiotics that help the problem after it has arisen vaccinations are given in an injection form and are dead or damaged micro-organisms of the virus you are being treated for. vaccination prepares the body and improves the immunity to a particular disease. The micro-organism is usually killed by heat or chemicals. Vaccinations and antibiotics Cons of antibiotics Pros for vaccinations Antibiotics are taken orally, topically or injected. They are drugs that kill bacteria which is caused by microorganisms , in minor cases such as acne or in more serious cases like pneumonia (lung infection) Antibiotics are not as effective on viruses as they are not alive.Whereas living bacteria are living organisms that multiply daily. Antibiotics The pros of antibiotics are: You can take them at home Most people can take them, only 1 in 15 people have an allergic reaction The advantages of antibiotics include controlling diseases, easy of use, and low side effects. They are available from the NHS and are free for people under 18. They can save lives and are able to effectively kill bacteria within the body. The antibiotics work quite quickly. The pros of using antibiotics Some people have adverse reactions and can have mild side effects such as headaches , nausea and swelling and soreness around the injected area. Sometimes side effects of the virus you are trying to treat. Few people suffer from major side effects although there haven't been many studies or supporting information to link the two together. Cons for vaccinations Vaccinatons Side effects such as diarrhea they can kill the healthy bacteria in the body, leading to other infection within the body. Research
Transcript: E-waste is a serious problem in developing countries like India, Ghana and china etc because of the toxic chemicals found in e-waste. The only reason countries like Ghana, India and China are affected by e-waste is all down to money. It costs 20 US dollars to recycle electronic devices in the US, but it costs just 2 US dollars in India to recycle E-waste in India! Why is e-waste a problem? E-Waste!!!!! But to retrieve these valuables safetly it cost lots of money and equipment which is not available in developing countries. So what is the solution Examples of E-waste in India E-Waste Everyday items like toasters and laptops have the potential to become e-waste.As most of them contain valuable elements like gold,copper and silver. In Mustafa Bad, a remote part of east Delhi, a narrow street is home to tiny workshops filled with hard workers. Inside, dozens of people, many of them children, spend tiring hours picking through the remains of old computers and mobile phones - hoping to find reusable parts to sell on for a tiny fee. According to the United Nations, 20-50 million tonnes of electronic waste - or e-waste - is produced every year. A large amount of it goes to recycling plants like this. E-Waste in China A massive e-waste landfill in Guiyu, in southern China's Guangdong province, is much more than a graveyard for old computers, says an investigative US writer based in Shanghai. E-waste is short for electronic waste. Electronic waste is discarded electronic devices that are no longer wanted, or needed by the consumer. no body knows,

TVs, monitors and screens. LED bulbs. Vending machines. Effects of E-Waste on the Environment Effects of E- Waste E-waste can pollute our soil and water systems and an increased risk of chronic diseases later in life. Electronic Waste could also lead to cardiovascular disease. Statistics surrounding E- Waste 44.7 million tonnes of e-waste around the world every year. That consists of 65 billion US dollars worth of materials like gold, silver and platinum. Last year, E-Waste was estimated to increase 17% to 52.2 million tonnes. E-waste represents 2% of America's trash in landfills. Statistics Images
Transcript: E- Waste Types of E-Waste Types of E-Waste Major appliances - refrigerators, washing machines, dryers, etc. Small appliances - vacuum cleaners, irons, blenders, fryers, etc. Computer and telecommunication appliances - laptops, PC's, phones, etc. Consumer electronics - video/audio equipment, musical instruments, etc. Lighting devices - incandescent light bulbs, fluorescent tubes, lamps, etc. Electrical and electronic tools - drills, saws, gardening devices, etc. Vending machines What E-Waste includes E-Waste includes: - non ferrous and precious metals - alloys - glass - ceramics - organic polymers with toxic content - and other substances like stabilizers, fillers and pigments. Effects of E-Waste The Negative Effects on Air The Negative Effects on Air The air pollution caused by e-waste impacts some animal species more than others, which may be endangering these species and the biodiversity of certain regions that are chronically polluted. Over time, air pollution can hurt water quality, soil and plant species, creating irreversible damage in ecosystems. The Negative Effects on Soil When large particles are released from burning, shredding or dismantling e-waste, they quickly travel into the ground to the soil. The amount of soil polluted depends on a range of factors including temperature, soil type and soil composition. These can remain in the soil for a long period of time and can be harmful to the soil and plants. Animals and wildlife relying on nature for survival will end up consuming these affected plants, causing internal health problems. The Negative Effects on Soil The Negative Effects on Water After soil contamination, heavy metals from e-waste, such as mercury, lithium, lead and barium, then leak through the earth even further to reach groundwater. When these heavy metals reach groundwater, they eventually make their way into ponds, streams, rivers and lakes which creates toxic water. This is unsafe for animals, plants and communities even if they are far away from a site. The Negative Effects on Water The Negative Effects on Humans The Negative Effects on Humans Electronic waste contains toxic components that are dangerous to human health, such as mercury, lead and lithium. The negative health effects of these toxins on humans include brain, heart, liver and kidney damage. it can also effect the system of the body and how it functions. The growing of e-waste will only worsen if we are not conscious of the effect it causes on our environment. Facts about E-Waste - In 2009, discarded TVs, computers, peripherals (including printers, scanners, fax machines) mice, keyboards, and cell phones totaled about 2.37 million short tons. - E-waste represents 2% of America's trash in landfills, but it equals 70% of overall toxic waste. - 20 to 50 million metric tons of e-waste are disposed worldwide every year. - Cell phones and other electronic items contain high amounts of precious metals like gold or silver. - Only 12.5% of e-waste is currently recycled. Statistics surrounding E-Waste Images and examples showing the everlasting effects of E-Waste Images and examples of effects of E-Waste Countries that have implemented policies to minimize E-Waste? Governments, in countries such as Japan and the Netherlands, have implemented policies that focus on minimizing e-waste. Successful e-waste recycling systems in Japan and Finland pay special attention to small electronic wastes, which is especially relevant to consumers.
