E-Waste - Presentation
Transcript of E-Waste - Presentation
- The circuit board, is made up of mined, raw materials like copper, gold, lead, nickel, zinc, beryllium, tantalum, coltan, and other metals. Input 2 Output Materials Processing LINEAR PROCESS Packaging and Transportation Useful Life End of life Recycling-Reusing-Disposing Material Extraction Materials Processing crude oil Processing copper Cell phones are 40% metals, 40% percent plastics, and 20% ceramics and other trace materials
- Copper, gold, lead, nickel, zinc, beryllium, tantalum, columbite-tantalite, and other metals
- crude oil, sand, and limestone
- liquid crystalline substances, glass, plastic, and a rechargeable battery
some of these materials need to be processed before use Crude oil + Natural Gas + Chemicals ---> Plastic.
This is done in a processing plant. Copper needs to be mined, ground, heated, and treated with chemicals and electricity before it can be used to make circuit boards and batteries. Finished processed materials - After processing, materials are shipped out to the manufacturers
- Transformed into the actual products
- Circuit board is a combination of plastic and fiberglass Step #1 Step #2 - Circuit board is plated with gold
- Circuits and wires are also put together to form the board
- These are mostly made of copper
- The circuits and wires are attached to the board with protective glues and other substances Step #3 - Two parts are need to produce the battery
- Electrolytes touch each electrode
- Outside source of electricity (e.g. an outlet) is applied to the electrode
- A chemical reaction occurs between the electrodes and the electrolytes
- This allows an electric current to be carried throughout the battery and the battery to function Packaging - Packaging protects products from damage
- Helps identify contents and provides useful information
- Excessive packaging is wasteful
- Most packaging comes from natural resources such as
- Paper (from trees)
- Plastic (from crude oil)
- Aluminum (from ore) Transportation - Typically made in China or the Unites States
- After packaging it needs transportation to global markets
- This is usually achieved with planes, trucks or trains
- Once it has arrived it is typically delivered to a warehouse and then divided up into smaller trucks to be taken to distributors.
- Transportation causes the burning of fossil fuels and the release of carbon dioxide into the air Cradle-to-Cradle Reduce, reuse, recycle/compost Material Re-utilization All materials used in cell phones must not have an impact on humans or the environment.
- This can work with using Bioplastic instead of regular plastic. bioplastic is plastic made out of plants and other composted things. Material Health The Cradle-to-Cradle cycle for e-waste isn't an easy one because not everything in cell phones or other electronic material can be replaced by something easily degradable with current technology.
- We have to try not to create more waste by recycling and using products for a reasonable amount of time (i.e. not buying every single new model of cellphone just because it is new). The C2C cycle Solar panels can make up the outside of a cell phone so that it can wirelessly charge and be completely renewable without using a battery. 100% renewable energy Water Stewardship Those involved in the process of creating cell phones must be payed well, allowed to live in fair conditions and not be discriminated against by their gender. Social Responsibility 18 months 1. Cell phones are thrown in the trash.
2. Taken to landfills - buried in the ground -they can also be burned in incinerators
- Contain hazardous substances including different metals, plastics, and chemicals.
- In Asia (where most of e-waste recycling takes place), parts of recycling sector remain unregulated. The recycling of e-waste has been poorly studied; information concerning its impact on the environment, the health of the recycling workers, and surrounding communities remains unknown. Parts Storage, Acid Processing, Burning, Residue dumping Water used in any part of the process used to make cell phones must be cleaned before being returned to streams, lakes, rivers or oceans. It must also be ensured that poisonous water does not impact local drinking water health - Majority of the substances contained in a cell phone are Persistent Bioaccumulative and Toxic (PBT) Chemicals.
- Very toxic
- Remain in the environment for a long time after disposal/transfer quite easily between air, water, and land.
- Biggest hazards are phone chips that contain circuit board, liquid crystal display, and batteries.
- Plastic casing is also hard to recycle.
- Handsets draw radio waves close to people’s heads .This can cause potential health risks. Ewaste recycling companies like Shift Recycling have been putting together initiatives to stop companies from sending their ewaste to be recycled in developing nations. International agreements prohibit the import and export of hazardous waste to developing countries, but still ewaste is sent to Kenya, India, and China to be broken apart and recycled. Green Technology Solutions, Inc. is working on bringing efficient and environmentally friendly e-waste recycling processes to places in need of them. The low regulations have made illegal dumping of e-waste from developed nations (like the US) an increasingly popular way to dispose of accumulated e-waste. In a measure to prevent this from continuing, Green Technology Solutions, Inc. is alerting the public about the situation at hand Since February of 2006, Verizon Wireless accepts used cell phones, cell phone batteries and accessories, as well as dead rechargeable batteries. People can drop off these items at any Verizon Wireless store, where they will recycle the e-waste at the company's Communications Stores. In 2005, Verizon Wireless collected and refurbished more than 850,000 cell phones. How to create Social responsibility for C2C - Enforce fair trade laws on cell phone companies who manufacture overseas
- Would also be useful to have labels for products, marking them as contributors to fair pay, gender equality and other initiatives. The same way as we have the ingredients listed on the back of cereal boxes. Renewable energy for C2C - No Plug
- Solar energy is 100% renewable
- The cellphone charger must be produced according to the initiatives (i.e. not with environmental harmful chemicals and definitely not in China).
- This would update the lifecycle of cellphones by implementing renewable energy technology (as long as it lasts). Safety for Workers - People in developing countries are often sent e-waste to be taken apart and it is very dangerous for the people who have to do this task
- All cell phone companies should take back their phones when people are finished with them
- They need to ensure that they won’t be sending them to developing countries Recycle - Taking apart old phones + reusing their pieces is very important
- Cellphone companies should be legally liable for the recycling of their toxic materials.
- Incentive wise, people could receive money for recycling cellphones Works Cited List http://www.etftrends.com/wp-content/uploads/2012/06/oil.gif
