What are the advantages and dis-advantages of plastics?

Answer 1

the disadvantage of burning plastic is that it will release toxic gasses which can kill. that's it really i cant think of any advantages.

magiclollyl Says:

Advantages:

~Due to a high BTU content it generates more energy than wood or coal.

~Relatively clean if burnt by an incinerator.

Disadvantages:

~Releases toxic gasses and chemicals.

~Expensive for it to be done cleanly.

Hope this helped you further :)

Answer 2

Advantages

Plastic is very useful in the building and construction, electronics (laptops wouldn't work well if they were made from glass), packaging (Gladwrap), transportation industries. Very easy to make - water bottles, plastic bags, pens, cups etc etc

The main advantages of plastic materials are also the reason why plastic is such a problem. It lasts forever and it is very cheap to make. When I say it lasts forever, I mean it does not biodegrade. There is a flotilla of plastic the size of Texas in the Pacific Ocean. It gradually photo-degrades into tiny pieces that enter the marine food chain.

Plastic is light, strong and cheap to produce. There are many advantages to using plastic. It does not decompose but it can instead be recycled. This is done more easily than producing more plastic. Unlike aluminum cans, plastic bottles can be re-used and stored over and over again. Plastic is usually not breakable and it is see-through. It's light-weight and odorless. Plastic comes from a natural resource (oil) but CAN'T be re-made into bottles (but they can be re-made into other items. It takes a long time to break down...

Advantages

The advantages of plastics are: Light weight, chemically resistant, can easily be shaped, durable, easy to color in the mass, thermostatically insulating, acoustically insulating, electrically insulating, energy saving.

More Advantages

1.Good response to temperature changes, 2. excellent resistance to many chemicals, .An excellent insulator, the surface resistivity of pmma is higher than that of most plastics, 4.Despite the hard conditions of heat, cold, sunlight, and humidity, pmma maintain their original appearance and color. 5. shatter-resistant,earthquake safe, and burglar-resistant. 6.At the same strength and durability, it is only half the weight of glass.

DISADVANTAGES

It is a compound that is indestructible, even when it is melted the compound gas that is gives off is very harmful to our heath and environment; it weakens the ozone layer. Most plastic is produced from oil. The world is gradually running out of oil. Scientists are now developing plastics that are made from vegetable oil and other organic matter. This means that the plastic is more likely to be degradable, so it will be less of a problem in future.

Threatening Disadvantage Another disadvantage is pollution.

Plastic accumulation in the environment is a looming catastrophe!

Think about this: Plastics are manufactured from petroleum. This brings a host of issues (destruction of habitat, extraction of crude oil, security issues from the volatile countries where oil is produced, processing of petroleum, chemical manipulation into various types of plastics). The manufacture involves many chemicals, many of which have not been sufficiently tested for their toxicological impact on humans or animals. The final plastic product is often a chemical entity that in and of itself has had insufficient toxicological and ecotoxicological testing. An example would be PVC, forms of which are banned in Europe but exist widely in children's toys in America. Recent controversies over plastic bottles (many toxicologists recommending not re-using plastic water bottles and not storing food in Tupperware) have highlighted the potential risks. Exacerbating the problem is that science is only now advancing to where it can detect plastic components in human blood and then trace concentrations and link them to human ailments and diseases. The plastics industry itself often spins plastic and related plastic chemicals into a variety of products, some of which are hazardous and controversial (Teflon, PVC, Polyethylene, polystyrene, various silicone in body and hair care). Plastic-producing companies are often chemical companies or subsidiaries of chemical companies, both with poor track records when it comes to their adherence to regulatory compliance and their willingness to perform toxicological analysis on the products they make. Plastics often leech component chemicals, including hazardous chemicals, through common temperature changes. It is for this reason that toxicologists do not recommend storing very cold foods in plastics or heating foods (microwaving especially) in plastics. Plastics are durable materials. Thus, they are hard to eliminate once used and create tremendous waste. While some common plastics can be recycled (#1 and #2 plastics used in common soda and milk bottles), the vast majority cannot. They take up a lot of space in landfills and create air pollution when incinerated
