The Different Types of Plastics and How they are Recycled

It’s in bottles, containers, wrapping, and other everyday items. Plastic is as versatile as it is recyclable. By recycling the plastics you use every day, you can reduce your impact on the environment and help businesses cut costs. However, not all types of plastics are created equal. The number within the recycling symbol on plastic containers provides a wealth of information about their safety, biodegradability and recyclability. Here’s a 101 of what these various SPI codes mean.

 

  1. PETE or PET (Polyethylene Terephthalate)

Commonly found in beverage bottles, perishable food containers and mouthwash, clear PET plastics are generally considered safe, but can absorb odors and flavors from foods and liquids stored in them. Most recycling programs accept this plastic. PET plastics are recycled into carpet, furniture, and fiber for winter garments.

 

  1. HDPE (High Density Polyethylene)

HDPE is another commonly recycled plastic deemed safe. HDPE products have a very low risk of leaching into foods or liquids. You’ll find this plastic in milk jugs, yogurt tubs cleaning product containers, body wash bottles and similar products. Many children’s toys are also made from HDPE. Recycled HDPE is made into pens, plastic lumber, plastic fencing, picnic tables and bottles.

 

  1. V or PVC (Polyvinyl Chloride)

Found in food wrap, plumbing pipes, tiles, windows and medical equipment, PVC is seldom recycled. PVC plastics contain harmful chemicals linked to a variety of ailments, including bone and liver diseases and developmental issues in children and infants. Keep PVC items away from foods and drinks. Specialized programs recycle PVC into flooring, paneling and roadside gutters to name a few.

 

  1. LDPE (Low-Density Polyethylene)

More recycling programs are beginning to accept LDPE plastics. A very clean and safe plastic, LDPE is found in household items like plastic wrap, grocery bags, frozen food containers and squeezable bottles. Recycled LDPE is made into such items as garbage cans, paneling, furniture, flooring and bubble wrap.

 

  1. PP (Polypropylene)

Another safe plastic, PP is quite sturdy and found in Tupperware, syrup bottles, medicine bottles and yogurt containers. PP is recycled into heavy-duty items like pallets, ice scrapers, rakes and battery cables. Many recycling programs accept PP.

 

  1. PS (Polystyrene)

An easily recognizable plastic, PS or Styrofoam is found in beverage cups, insulation, packing materials, egg cartons and disposable dinnerware. Styrofoam is notorious for leaching and poor recyclability, though some programs may accept it. PS is recycled into various items including insulation, school supplies and license plate framing.

 

  1. Miscellaneous Plastics

SPI code 7 is a potpourri of plastics, one of which is polycarbonate. Sunglasses, computer casing, nylon, compact discs and baby bottles may contain #7. These types of plastics are hard to recycle and contain the toxic chemical BPA, a dangerous hormone disruptor that can cause health problems. Plastic #7 is primarily recycled into plastic lumber and specialized products.

Plastic Recycling Process and Plastic Recycling Machinery

Thermal depolymerization, polymer plastic. The use of the plastic is increasing now a day like water is coming in the plastic bottle and the colas are also coming in the plastic bottles. Both of the different types of drink use in a huge amount by the people and it is not only using in some countries but the usage of the plastic bottle is in huge amount in each and every country. After drinking the material from the bottle most the people throw it in the bin as they consider the empty plastic bottle as the waste.

 

The recycling of every type of the plastic is necessary because the plastic which is empty and which has no use in the world and pollute the environment in one and the other way. If the empty plastic bottle will not recycled and it if burn then by the plastic the carbon will evolved in the air which pollute the environment and is also dangerous for the human being living near the area in which this type of activity is going on. The plastic recycling can save the environment and it also effect on the consumption and making the new plastics.

 

It is also not necessarily important that if the bottle of the plastic is recycled then after the process the recycled plastic will not use in making the same type of the commodity again. Once the plastic is recycled the is melted it can be used in making the different commodities like the plastic of the pet bottle is recycled then the chair of the plastic can be made through that re cycled plastic. Recycling is important because it also affect the cleanliness of the city. Especially the recycling of the pet plastic bottle is more important as the pet bottles after consumed is throw in the waste and is seen in the third world countries that the bottle made of the plastic can be found on the ground.

 

One of the challenge faced in recycling of the plastic is that as compare to the glass the recycling of the plastic need long process and so it require the time and the plastic recycling machinery rather that it is the fact that after the recycling of the plastic it is more useful than the glass or any other thing with which the same things can made. The structure of the plastic bottles are very intense type of the structure as it is made up of the polymer plastic so that the heating is not enough to melt the plastic it need more process than simple heating the bottle in the machine like one again the example of the glass is consider.

 

As there are many type of the plastic so that before the plastic goes in the recycling it should be categories. The plastic is categories on the level of the polymer used in making the plastic. The process in recycling is monomer recycling then thermal depolymerization and last step is heat compression.
