Like paper, when plastic has been used, it can go to one of two places: The landfill or the recycling center. In a landfill, plastics make up 7% of the waste by weight, and 18% by volume. Of the 44,100 million pounds of plastic products made each year, 26,700 million pounds ends up as municipal solid waste.As landfill useage decreases each year, it is becoming more popular to incinerate our garbage. Today, with the requirement of emission controls on smoke stacks, burning garbage is 99.9% cleaner than in days of yore. About 10% of all garbage is burned, of this, plastic makes up, as previously stated, 18%.
One of plastics greatest assets is its recycleability. To recycle almost any kind of plastic is to mearely re-melt, and re-form. The re-melting will sterilize, allowing any recycled plastic to be used in even hospital grade products. And plastic can be re-formed into anything, many times over before it becomes brittle, whence it can be made into an ashtry or a mouse pad. If society were to implement a strict plastic recycling, an enormous percentage of plastic would efficiently be used, again.

Plastic Bag Litter
Even when citizens try to manage their plastic bag disposal wind plays a role in carrying them away as litter. This litter is not biodegradable and thus where it lands it tends to stay for long period of time. A bag that is eventually ripped to shreds from high winds or other factors doesn't disappear but instead is spread in smaller amounts throughout the area. This can cause more problems as these smaller pieces are carried away through storm drains and often end up in the waterways.
Plastic bag litter is often also the result of human laziness. The plastic bag might make for a good carry on to the beach for the day but once all of the pretzels and chips are consumed an estimated one in three consumers simply allow the bag to disappear into the wind and waves.
With more the 500 billion and possibly as many as a trillion plastic bags in circulation annually this can lead to a catastrophic littering problem. Not only is littering unattractive but it is also a very serious environmental hazard.

The Effects of Plastic Bags in Waterways
One of the greatest problems is that an estimated 300 million plastic bags end up in the Atlantic Ocean alone. These bags are very dangerous for sea life, especially those of the mammal variety. Any hunting mammal can easily mistake the size, shape, and texture of the plastic bag for a meal and find its airway is cut off. Needless deaths from plastic bags are increasing every year.
Porpoises are the most common victim. Because they eat sea nettles and jelly fish they are the most likely to mistake the plastic bag for food. If they survive the swallowing of the bag, it is unlikely that they are able to continue with normal digestion and thus eventually die a slow and painful death from toxicity or intestinal blockage.
The environmental balance of the waterways is being thrown off by the rate of plastic bags finding their way into the mouths and intestinal tracts of sea mammals. As one species begins to die off at an abnormal rate, every other living organism in the waterway is impacted. There are either too many or too few and changes within the environment continue to kill off yet more organisms.

The Effects of Plastic Bags on Land
The indefinite period of time that it takes for the average plastic bag to breakdown can be literally hundreds of years. Every bag that ends up in the woodlands of the country threatens the natural progression of wildlife. Because the break down rate is so slow the chances that the bag will harmlessly go away are extremely slim. Throughout the world plastic bags are responsible for suffocation deaths of woodland animals as well as inhibiting soil nutrients.
The land litter that is made up of plastic bags has the potential to kill over and over again. It has been estimated that one bag has the potential to unintentionally kill one animal per every three months due to unintentional digestion or inhalation. If you consider the number of littered plastic bags ranges from 1.5 million to 3 million depending on location, this equals a lot of ecosystem sustaining lives lost.
Without the balance of the ecosystem food sources dry up and starvation occurs. With an increase in plastic bag use throughout the world, the eventual effects could be literally devastating even to the human population.

Recycling Plastic Bags
While it's a noble thought to place the plastic bags in the recycling bin every week, studies have proven that there are very few plants that actually recycle them. Most municipalities either burn them or send them off to the landfill after sorting. This is because it can be expensive to recycle this type of plastic. It doesn't melt down easily and is often not realistically able to be reused from its original form without considerable overhaul to the facility.
The premise of recycling these bags is nice. Yet funding for the upgrades just has not happened and thus less than 1% of all bags sent to recycling plants world wide end up in the recycling project. Most are left to become a pollution problem in one way or another.

Plastic impacts in two ways: First, it hits the environment in its use of electricity when being manufactured. More than half of the power needed to make plastic bags is generated by nuclear fission. While controversial, it is argued that nuclear power puts no direct harm or detriment into the environment. The only drawback to nuclear power is the radioactive waste, which is, so far, being safely disposed of in deep underground caves. And, in deep sea trenches where the nuclear waste is subjected into earths mantle and incinerated.Pertaining to the rest of the electricity needed to make plastic bags, coal fire does pollute. But, plastic can be burned. In fact, the burning of plastic will yield from 10,000 to 20,000 btu per pound, of which 60% can be recovered. As stated above, plastic is burned to create electricity, hence, we could use plastic to make plastic, and reduce sulfur emissions from coal.
There is the question, though, of recovery of energy by burning plastic. This, too, causes controversy but only because of mental block. If 93% of all oil is burned straight away, why can't the 4% used as plastic have a second life as energy? The burning of plastics isn't without its drawbacks. Inks and additives to some plastics can create dioxins, and emit heavy metals when burned. Also, after being burned, the toxic ash still needs to be disposed of in toxic wase dumps. Another problem with the incineration of plastic is the argument that the energy produced by the process doesn't justify the misuse of a limited natural resource. The plastics already produced are better utilized by making new plastic materials by recycling.
The second way plastic impacts is through landfills. Plastic will never break down; It will never disappear. Biodegradable plastic is a misnomer because wood fiber has been mixed with the plastic so when buried, the wood dissolves leaving a million tiny pieces of plastic, instead of one bag. As stated, plastics make up 18% of waste by volume, and 7% by weight. If plastic were to be replaced in its uses by other materials, rubbish weight would increase by 150%, packaging would weigh 300% more, and energy consumed by the industry would increase by 100%. It has been found that the reduced weight of plastic has spillover benefits, elsewhere. Reduction of weight in aircraft saves an average of 10,000 gallons of fuel per plane, per annum, world over. In automobiles, it is directly responsible for doubling the fuel efficiency since the 1970's. Applied to plastic bags, they reduce weight in landfills; They take up less space. This being in light of the discovery that most landfills are air tight, not allowing decomposition, leaving readable newspapers and chicken bones with meat still on them.
