What is plastic waste ? ? Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products, sometimes completely different in form from their original state. Since plastic is nonbiodegradable, recycling it is a part of global efforts to reduce plastic in the waste stream, especially the approximately eight million metric tones of waste plastic that enter the earth's ocean every year. This helps to reduce the high rates of plastic pollution.
The recycling materials Plastic recycling includes melting down soft drink bottles and then casting them as plastic chairs and tables. However, this kind of "recycling" is rather a misnomer since plastic beverage bottles (soda, juice, milk) are never truly reformed into new beverage bottles, as this requires virgin plastic. So there is actually no true cycle in the "recycling" of plastic beverage containers, which actually and more precisely should be referred to as "downcycling".
Plastics are also recycled during the manufacturing process of plastic goods such as polyethylene film and bags. A percentage of the recycled pellets are then reintroduced into the main production operation. This closed-loop operation has taken place since the 1970 s and has made the production of some plastic products amongst the most efficient operations today.
The quantity of post-consumer plastics recycled has increased every year since at least 1990, but rates lag far behind those of other items, such as newspaper (about 80%) andcorrugated fiberboard (about 70%).  Overall, U. S. post-consumer plastic waste for 2008 was estimated at 33. 6 million tons; 2. 2 million tons (6. 5%) were recycled and 2. 6 million tons (7. 7%) were burned for energy; 28. 9 million tons, or 85. 5%, were discarded in landfills.
What about plastic pollution? Plastic pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, or humans. Plastics that act as pollutants are categorized into micro-, meso-, or macrodebris, based on size. The prominence of plastic pollution is correlated with plastics being inexpensive and durable, which lends to high levels of plastics used by humans.
. However, it is slow to degrade. Plastic pollution can unfavorably affect lands, waterways and oceans. Living organisms, particularly marine animals, can also be affected through entanglement, direct ingestion of plastic waste, or through exposure to chemicals within plastics that cause interruptions in biological functions. Humans are also affected by plastic pollution, such as through the disruption of the thyroid hormone axis or hormone levels. Plastic reduction efforts have occurred in some areas in attempts to reduce plastic consumption and pollution and promote plastic recycling.

Waste Management Planning Waste management planning is the cornerstone of any national, regional or local policy on waste management. The establishment of a plan allows taking stock of the existing situation, defining the objectives that need to be met, formulating appropriate strategies, and identifying the necessary implementation means.
