Plastic Recycling: The Facts You Need to Know
Different Types of Plastic
Look at the underneath side of a plastic bottle or plastic container. Inside the familiar reduce, reuse, recycle triangle (“chasing arrows”) logo is a number between one and seven. This number indicates what kind of plastic that container is made from. Some plastics are easy to recycle, but other plastics are much harder to recycle. As a result, most municipal recycling facilities only recycle the easiest plastics: plastics 1 and 2. What happens to plastics 3 through 7? At some recycling facilities, these are gathered until they have enough to send to a larger recycling facility that does recycle these types of plastics. But at other recycling facilities, the same thing happens to plastics 3 through 7 as what would have happened at your house if you didn't have that handy recycling bin: it goes to the landfill, or the Pacific's Plastic Continent.
Plastics #1 and #2
Plastic #1 is polyethelyne terephthalate (PET). This is the most commonly used plastic, and it\'s the easiest to recycle. Your plastic soda bottle, salad dressing bottle, and cooking oil bottle are probably all made from PET. More than 2.3 billion pounds of PET are recycled annually.
Plastic #2 is high density polyethelene (HDPE). Most milk jugs, detergent bottles, and many food containers are made from HDPE. Unfortunately, some plastics marked with a #2, such as yogurt cups, are not actually recyclable. This is because other chemicals have been added to the plastic in order to mold it into the desired shape. These additives make recycling some of these #2 items basically impossible.
Plastics #1 and #2 make up 96% of all the plastic bottles produced in the United States. Nevertheless, 80% of plastic bottles still wind up in a landfill, even though 80% of Americans have access to a method for recycling these bottles.
Plastics #3 through #7
The rest of the plastics make up pretty much everything that\'s not a plastic bottle. Just think of all the plastics in your home -- your toothbrush, cling wrap, plastic bowls, plastic cups, drinking straws, last night\'s leftovers, that almost-impossible-to-open package your new iPhone came in, your computer, your DVD cases... plastic is everywhere.
These plastics can all be categorized as the plastics #3 through #7. None of them are particularly easy to recycle, so even though your recycling guy will take it from your curb, that doesn't necessarily mean it will become tomorrow's soda bottle. However, by researching recycling facilities in your area, you can find places to recycle these less common plastics.
The Bottom Line When it Comes to Plastic Recycling
Plastic is much harder to recycle than other materials. Because it breaks down during the recycling process, it can only be recycled so many times -- this is why many recyclers prefer so-called “virgin plastics”, or plastics that haven't been recycled before because they make a better product. That means that even if you do the best you can to recycle all your plastics, some of them might still wind up in the dump.
The clear conclusion we must draw is that even the most conscientious recycling is not enough when it comes to plastics: ultimately, we have to reduce our consumption. The process of producing plastics, many plastics themselves, and the aftermath of plastic use can all be described as toxic. Nearly all manufacturing processes for the different types of plastic listed above involve some degree of toxicity, and as these plastics disintegrate in landfills or in the ocean, these toxic chemicals find their ways back into our soils, our water, our food, and our bodies.
So please recycle plastic. But better yet, stop buying plastic wherever possible.

Benefit of Plastic Recycling and Its Application
If we take the look of plastic use in our lives then plastics came into our lives in the 1950's; however the question is the “safe use of plastics”. Plastics is a part of our everyday living from cups to auto parts. But it soon became damage on our environment.
Plastic Recycling is a multifaceted process because different types of plastics cannot be mixed before recycling. Plastics of different polymer structures as well as resin composition are identified by using standard codes on the basis of their melting and crushing capacity.
Help to conserve energy: Recycling of plastic needs very less energy so in this way it saves twelve thousand BTUs (British Thermal Unit) when one pound of PET bottles are recycled.For More Details Please Visit Us At : Plastic Industry | Plastic Trade Portal | Plastic Recycling | Global Plastic B2B Marketplace | Online Plastic B2B Trade Portal

Basics Information About Plastic
The word plastic is derived from the Greek word "plastikos" meaning capable of being shaped or molded, from plastos meaning molded.It refers to their malleability, or plasticity during manufacture, that allows them to be cast, pressed, or extruded into a variety of shapes—such as films, fibers, plates, tubes, bottles, boxes, and much more.
What is plastic?
Plastic is a common name for Polymers: materials made of long strings of carbon and other elements. Each unit in a string is called a monomer, and is a chemical usually derived from oil.
The monomer is made into polymer by chain-linking reactions. This is like making a daisy chain. Instead of flowers, carbon atoms are joined together. The appearance of the daisy chain will be different if you use different coloured flowers, and so will polymers.
There are many different types of plastic, depending on the starting monomer selected, the length of polymer chains, and the type of modifying compounds added. Each plastic has been developed for a special purpose.
There are two main groups of plastics:
1. THERMOPLASTICS soften with heat and harden with cooling.
* Some typical thermoplastics are: Acrylic (Perspex)
* Acrylo-nitrile (Nylon)
* Polyethylene (Polythene)
* Polypropylene
* Poly Vinyl Acetate (PVA)
* Poly Vinyl Chloride (PVC)
* Polystyrene and ABS
* PTFE (Teflon)
2. THERMOSETS are cured or hardened by heat.
Some typical thermosets are:
* Bakelite
* Epoxy
* Melamine
* Polyester
* Polyurethane
Properties
Plastics are used because they are:
* Attractive
* Hard and slippery
* Soft and rubbery
* Tough and slippery
* Flexible
* Good insulators of heat or electricity
* Light weight
* Hygienic
* Non-rusting
* Easy to shape and colour
* Cheap
The tremendous growth of the plastics industry is expected to continue..The factors that have contributed to this growth include the energy efficiency of plastic world market. All studies show that it takes less energy to make a product from plastics than just about any other material.
Steps Of Plastic Recycling Process
Nowadays, plastic becomes an essential part of our daily life. However, plastic world market is growing very fast as compare to any other market of the world so industrialist have to take care that their new inventions will not affect the planet environment as well as health of human beings. Plastic recycling is the process of collecting certain materials that would otherwise be considered waste — like old metal, paper, wood, or plastic for example — and turning them into new “recycled” products.
The whole plastic recycling process is described by seven steps as described below:
Some plastics for recycling :-
1 - PET or PETE (Polyethylene Terephalate Ethylene)
Light weight, low-priced, and easy to fabricate, Polyethylene Terephalate Ethylene is the most prevalent plastic material in use today. PET is primarily used in beverage bottles, food receptacles, and peanut butter containers. It can be remade into polar fleece, fiber, carpet, etc. The requirement for this plastic among recyclers is relatively strong, but at present, the recycling rate for this material has remained low at 20%.
2 - HDPE (High Density Polyethylene)
High Density Polyethylene is more durable and more impervious to chemical degeneration, this material poses a relatively low chance of spreading chemicals when used as container for food and drinks. It is largely used as containers for everyday household chemicals (shampoos, degreasers, etc.), juice bottles, milk jugs, etc. This can be reused into floor tile, drainage, new HDPE bottles, pipes, etc.
3 - PVC (Polyvinyl Chloride)
PVC has been tagged as a health hazard - it has been noted to typically drain chemicals when used as containers. PVC is mainly used for piping, window cleaner bottles, siding, etc. It has chlorine and will dispense toxins if burned. PVC should not be used in food preparation or food packaging. It can be reprocessed into mudflaps, panels, mats, etc.
4 - LDPE (Low Density Polyethylene ) LDPE is the material present in plastic bags, clothing, furnitures, etc. Resilient and flexible, it is perfect for packaging, insulation, and sealing. LDPE, through many curbside recycling programs, can be reconstituted into cans, compost bins, and landscaping tiles.
5 - PP (Polypropylene)
Polypropylene is most suited for boiling fluid receptacles and is likewise made into brooms, straws, ketchup bottles, etc. PP can be reprocessed into rakes, brooms, trays, etc.
6 - PS (Polystyrene)
PS is the top component for insulation and is used in foam products like expanded polystyrene (EPS), commonly known as styrofoam. It is found in carry-out food containers, meat trays, CD cases. PS contains benzene, a cancer-causing substance and should not be burned. It is reprocessed into insulation, packaging, plant beds, etc.
7 - OTHER (Polycarbonate)
For Plastic Recycling
7 - OTHER signifies materials not belonging to any of the other 6 resin categories. OTHER may also signify a hybrid resin made up of a mishmash of those materials. It is mainly found in children feeding bottles, flak jackets, business signages, five-gallon water jugs, etc. It can be recycled into plastic planks and other tailor-made objects.
Not all number 7 plastics are polycarbonate, a handful are even plant-based. Polycarbonate has become the axis of dispute in recent years, as it is discovered to leach BPA (bisphenol A), a hormonal disruptor that may disastrously influence gestation and fetal growth.
