    Most plastic bags are produced using oil. Oil drilling is harmful to the environment and our addiction to oil is making our nation less secure, while damaging our economy. (Though of course there are other problems with security and economy.)

    In addition, plastic bags that are not recycled will eventually end up in a landfill or in the ocean. Plastic does not even begin to biodegrade for hundreds of years. This allows it plenty of time to wreak havoc in ecosystems. For instance, sea turtles mistake plastic bags for jellyfish, and eat them. The plastic blocks their digestive tracts, causing painful deaths.

    Have you ever heard of the Pacific Garbage Patch? It's a plastic continent, at least twice the size of Texas, floating in the Pacific. It's composed of waste, most of which originated on land.

    Recycling plastic bags is essential, but even this uses considerable energy, which pollutes the air.

    Banning plastic bags would alleviate these problems. However, plastic must be replaced with reusable bags, not necessarily paper.

    The problem is, people are accustomed to cheap, convenient lifestyles, and many are unwilling to switch to reusable bags. But I use cloth bags at Target and Winn-Dixie, and I find them to be much more convenient than plastic or paper, because they are sturdier and hold more stuff.

    So the only real disadvantage that I can think of is that the plastic bag industry would suffer, which is not good is this economic climate. Others might disagree, but IMHO the environment is more important than big business.

    A final note: As Plastic bags do not account for all of the plastic waste we produce. Most items in stores are over-packaged and use excessive plastic, because the packaging is used for advertisement, not just to protect the product. In order to solve the problems caused by plastic waste, we must recycle, decrease and/or eliminate all plastic, not just bags.

    Nowadays, Landfill and burning waste plastic is not the only way to disposal waste plastic. Moreover landfill and burning will cause pollution to environment and also waste lots of land. And now waste plasticcan recycle by waste plastic recycling machine then pyrolysis waste plastic to fuel oil and diesel under some conditions.

    But, what benefits we can get from recycling waste plastic?

    First, we can get fuel oil, carbon black by pyrolysis. In Mexico, our customer told us, fuel oil price is about 650usd per ton. And also diesel oil has a nice price about 800usd per ton. Let’s see a profit analysis from Macedonia client his material is waste tyres, waste plasic have a good price and good oil quality than tyres:

    Profit analysis from Macedonia customer(10 tons tires capacity)

    No Item Cost of each batch

    1 10 tons of waste tire 10T*USD 42.5/T=USD 425

    2 0.4 tons of coal 0.4T*USD 70/T=USD 28

    3 Electricity and water 244kwh*USD 0.26=USD63.44

    4 Workers 4*USD 15=USD 60

    Total cost USD 576.44

    Income for one batch

    1 Crude oil 4.5T*USD 960=USD 4,320

    2 Steel wire 10T*15%*USD 350/T=USD 525

    3 Carbon black 3T*USD 20/T=USD 60

    Total income USD 4,905

    Profit

    1 Daily profit USD 4,328.56

    2 Month profit USD 4328.56*25 days=USD 108,214

    3 Annual proft USD 108,214*10month=USD 1,082,140

    In addition, in some place, the recycler of waste tyres can get some allowance from the local government. Waste tyres recycling machine become more and more popular.
