Plastic Waste Management



Over 23 MILLION TONS of the world’s yearly trash load every year is plastic. Plastics are so durable that they will not rot or decay as do natural products such as those made of wood. As a result great amounts of discarded plastic products accumulate in the environment as waste. They do not burn easily; instead, they melt and simply accumulate at the bottom of the incinerator.
Here are the different types of plastics that have a detrimental impact on the environment:

Of course, plastics are generally very lightweight. When plastics are buried in a landfill, they occupy about 25 percent of the space. Putting plastics into landfills is not always the best disposal method. There are two other alternatives: recycling and incineration.

These methods recover some of the value from the plastic. Recycling recovers the raw material, which can then be used to make new plastic products. Incineration recovers the chemical energy, which can be used to produce steam and electricity. Land filling plastics does neither of these things. The value of land filled plastic is buried forever.
