Electronics Recycling

Electronics Recycling

Society’s technological advancements have grown significantly over the years. Electronics devices such as telephones, cell phones, radios, CD and DVD players, televisions, and computers are products that are used in every household. These items are just a few of the many electronic devices that can cause serious environmental damage due to their toxic components. Electronics that are in need of disposal are referred to as e-waste, or electronic waste. Because of the advancement of electronic products, there has been a growing concern about the hazards of electronic waste. Some of these concerns include: improper disposal of toxic materials, health and safety concerns for people disposing of these items, as well as dangers to the soil and water supply. For instance, electronics are made using a considerable amount of toxic substances such as lead, cadmium, aluminum, zinc, copper, and plastics which can all leak poisonous material in the ground and water. These environmental concerns have resulted in the establishment of electronic recycling facilities and industries who take old electronics such as computers for the purpose of recycling and safe disposal.

Electronics containing materials such as metals, plastic, are valuable to the recycling companies. Disposing of electronics through a recycling company will result in fewer electronic devices going into landfills and lower carbon emissions.

Recovering Raw Materials: Recycling electronics involves recovering raw materials from the electronic equipment. Materials such as steel, copper, wires, aluminum, brass, plastics, glass,etc., are extracted and sold to smelters so they can create raw materials. Depending on the type of metal being extracted, they can be processed and used in products required by such businesses as the steel, construction and cement industry. Plastics and wood can be used as fuel to provide heat to industrial furnaces which converts to steam. Metals such as copper are sold to metal refineries.

Plastics: Plastics from such items as computers, computer mice, and keyboards, are sent through shredding processes and machine sorted. They are then sent to other recyclers for further processing.

Larger Electronics: Items such as televisions and computer monitors are dismantled by hand. The leaded glass cathode ray tubes are removed and disposed of safely. Plastics, copper, and circuit boards are removed, separated, and processed.

Hazardous Items: Toxic items are removed from electronic devices and disposed of safely. Toxic substance can include leaded glass, rechargeable batteries, non-rechargeable batteries (i.e.alkaline, lead acid, cell batteries) mercury in lamps and switches, parts containing polychlorinated biphenyls, as well as ink and toner cartridges. The remaining non toxic materials are processed and the recyclable materials are recovered. The materials are shredded and separated according to type. For instance, they can be divided into such materials as steel, copper, aluminum, and plastic.

Refurbished Electronics: There are now many companies that acquire used computers, repair and update them, and resell them at a much lower price. This is a great way to keep electronics out of landfills and make technology more affordable.

Donate Your Computer: If you are getting rid of your old computer because of a recent upgrade, consider donating it to charity. Many schools and non profit organisations are in need of computers. There are companies and businesses that will take your computer, refurbish it, and donate it to a needy cause. Make sure your computer is wiped clean of all information before donating it. Donating your computer helps the community and the environment.

We are fast becoming a technology dependent society. When it comes to protecting and conserving our environment, we have to adapt and change our technological practices to ensure a sustainable future. Recycling electronics is a great way help the planet.

Know that repairing a computer or laptop repair Toronto is not cheap, but it can be cheaper than having to replace the computer. If you run into these situations, you will need to hire a onsite computer repair service Toronto.

Are Tsunami’s Caused by Global Warming?

Are Tsunami’s Caused by Global Warming?

Throughout the history of our planet it has endured a constantly changing climate. It endured an ice age and has also experienced long periods of heat. But over the last two hundred years, give or take, the temperature of our planet has been steadily increasing. This change in the climate on earth is known as global warming, and global warming is the direct result of the industrial revolution.

Because of the industrial revolution, people are constantly burning fossil fuels such as oil and coal. But by burning these fuels dangerous greenhouse gases like carbon dioxide (CO2) are then released into the earth’s atmosphere. These gases block heat rising from the earth from being able to escape into space. The same basic function that glass panels on greenhouses have, hence the name. Our burning of fossil fuels causes more than three quarters of all carbon dioxide emissions. Power plants and other stationary sources contribute more than half of that amount.

Along with increasing CO2 emissions, deforestation is on the increase as well. This is disastrous, because trees recycle CO2 and release oxygen back into the atmosphere. Because of the rise in deforestation levels the fossil fuels we burn are seriously jeopardizing our planet. We know that global warming is the cause of glaciers getting smaller and for the rise in sea levels. Plants and animals show clear and undeniable signs that they are affected in many different ways. Earth is experiencing longer seasons which results in rivers and lakes freezing later than usual and melting sooner. Without a doubt, global warming causes many changes and affects our planet in many ways but can it also cause a tsunami?

Nobody will ever forget the utter destruction, grief and loss left behind after the huge tsunami that hit parts of Asia on December 26th, 2004. Hundreds of thousands of people were killed, injured and traumatized. The areas it hit were left completely destroyed.

Generally speaking a tsunami is made up of a series of waves. More often than not the first one is the mildest. Prior to the arrival of the first wave, the shoreline recedes dramatically and often leaves the ocean floor exposed. They mostly occur where the water is shallow but they can also occur around coastal areas. In deep water a tsunami appears as a big wave and nothing more. In shallow water this is not the case. The wave can reach as high as one hundred metres, although, in all honesty, this is not at all common.

We know that tsunami’s can be caused by an earthquake, but this is not the only cause. They can also be caused through volcanic eruptions and landslides. Another cause is if a large amount of water is somehow displaced, such as when meteors happen to fall into large bodies of water. Tsunami’s are caused by events that can be, and are, affected by global warming, however global warming itself does not directly trigger the formation of a tsunami. Basically, it is an indirect cause.

One thing is certain, global warming is not a myth as some suggest. The planet is displaying clear signs that we dare not ignore.
