Transcript of Polymer Waste

Problems with polymers By Safa Saeed :) Problems How can we help? We can help by... ...Ideas .... More info: How can burning polymers affect our lives? What will happen if I burn them? Why are polymers a problem? The best way... Never burn polymers: Now... Whats happening in the future? You shouldn't burn polymers because they give of toxic products such as: New processes are being developed by which polymers can be cracked to give new alkenes, waste products are now being used for fuels, for example power generators.
...The New polymers are being produced are compostable and biodegradable. ...is to recycle the polymers, however there are further problems with this. Recycling them can be difficult as there are different types of polymers therefore difficult to separate. As it's difficult to separate it costs allot of money to do so. Plastics that are made from recycled polymers are low quality therefore there is a less chance of businesses buying recycled plastics which can lead allot of recycled plastics, wasted. Polymers such as polyethene contain non-polar bonds (e.g. C-H) or strong bonds (e.g. C-F), because of these bonds it makes them unreactive.
Most people who burn their plastic domestic waste do not realize how harmful this practice is to their health and to the environment. Current research indicates that backyard-burning of waste is far more harmful to our health than previously thought. It can increase the risk of heart disease, aggravate respiratory ailments such as asthma and emphysema, and cause rashes, nausea, or headaches, damages in the nervous system, kidney or liver, in the reproductive and development system. The burning of polystyrene polymers -such as foam cups, meat trays, egg
containers, yogurt and deli containers releases styrene. Styrene gas can readily be absorbed through the skin and lungs, which is not good at all. ...making useful products that you can sell, use or gift... For more information ask any chemistry teacher or a polymer expert for more information on how polymers are a problem:

For reusing polymer ideas check on YouTube.

As polymers don't react, it makes them non-biodegradable. Therefore they persist in the environment and cause litter problems. It is particularly hazardous to burn poly(chloroethene)
aka PVC, as toxic compounds such as HCL and poly chlorinated biphenyls (PCB s) are formed. Carbon monoxide, oxides of nitrogen or hydrochloric acid, depending on the polymers structure. Chemists are finding ways of removing toxic compounds: for example, HCL is removed as hydrochloric acid, by passing the waste gasses up into special spray towers. How the spray towers work is sadly top secret. For example, Polymers formed from isoprene are used to make babies' nappies and photographic film. ... for helping the environment and each other we can get ideas from many sources including each other on how we can use polymers without wasting them.
