Polyethylene terephthalate, or PET, is a type of plastic resin as well as a form of polyester. It can be fully recycled, in which case it becomes recycled polyethylene terephthalate, or rPET. Essentially, the material is a polymer, which is made by combining purified terephthalic acid and modified ethylene glycol, both monomers. PET was originally discovered in in the United Kingdom, where it was also patented.
If you grab a container or bottle, you may notice a #1 code on the bottom of it. That is to say it is made out of PET. It is very common as a packaging material, including things like peanut butter, beverages, produce, bakery goods, salad, frozen foods, cosmetics, dressings, and household cleaners. PET itself is incredibly popular because it is transparent, thermo-stable and incredibly durable. Additionally, it is lightweight, affordable, shatter resistant, resealable and, most important of all, recyclable. This is where rPET comes in.
rPET is created by recycling plastics that were previously used as packaging materials. These include plastic bottles, for instance.
Once collected, it is sorted and cleaned, after which it is transformed into rPET, which can then be used for new packaging. This is federally approved and effectively means that you can give each bottle a new lease of life.
By recycling PET bottles and turning them into rPET, you conserve a great amount of landfill space.
In fact:
There are a number of other interesting things to know about recycling PET:
rPET can be used in a huge variety of ways. These include:
This shows the breadth and width of possibilities offered by PET. Perhaps most interesting is the fact that 100% of all PET can actually be made from rPET. It is so versatile, as well, that it can be used for food and non-food products alike. It is, in fact, so safe, that it can be recycled over and over again, reusing each element to create new ones each time. Many custom reusable shopping bags & totes made from rPET (see rPET custom bags and totes ) materials are popular today and some of our best sellers.
Both in this country and in Canada, there is a huge demand for rPET. The demand is, in fact, so high that insufficient bottles are being collected to meet it. This is because rPET can be used in so many different new products. As a result of this shortage, some new PET must also be created. Consumers now actively look for companies that are committed to sustainability, recycling, and the overall green agenda. As such, manufacturers improve their standing by using rPET as much as possible.
Usually, PET is collected through programs such as curbside recycling. This involves both what is known as a single-stream approach and a dual-stream approach. However, because there is such a shortage of PET, other recycling programs are also being set up in different communities across the country. For instance, there are recycling banks and recycling drives, and various community education programs exist in order to further promote recycling.
At a recycling center or material recovery center, PET is sorted from the various other recyclable materials. It is then baled, after which it is sent to specific PET recycling facilities. These are federally authorized to process the material. It is very important that PET is stored and handled properly, however, so that it is not contaminated and so that the workplaces are 100% safe. This is why various federal regulations are now in place.
Once the bales of PET arrive at a recycling facility, they are first staged. Then, they are placed onto a conveyor, which takes them through a bale braker. This brakes the bales, and the bottles then become singulated. It is vital that all bottles are properly washed and that their labels are removed. Steam is used, as well as various chemicals. To do this, the bottles are placed into a hot air trommel, which is known as the &#;pre-wash stage&#;. If any PVC bottles have accidentally made their way into the bale, they will turn slightly brown during this process. This then enables them to be removed.
Most licensed PET facilities use near infrared (NIR) equipment to sort through the bottles and to remove contaminants. They usually also use metal detectors to further sort the materials. Finally, they will go through a sorting belt, where employees remove any final materials, leaving just the PET in place.

After sorting, the material is then ground, which creates what is known as &#;flakes&#;. These flakes have to be completely pure in order to make sure they can be turned into rPET. If they are contaminated, functionality, strength and, ultimately, value will be significantly reduced. This is why various separation techniques are usually used along the way, including air classification and washing.
Once all the steps have been completed and the facility is sure that no contaminants remain, the material is rinsed one more time. After it is dried, it becomes a new manufacturing material by being reintroduced. Actually, manufacturing new items out of the rPET is generally done at other facilities.
Sometimes, however, the material has to be purified even more. This can be done though melt filtering. This means that any contaminants that still remain that don&#;t melt will be taken out of the rPET. The melted material passes through screens, eventually forming pellets when drying again. This is known as pelletized plastic, which is more efficient for transportation and re-manufacturing, as well as providing more uniform sizing.

With a push towards sustainable business and personal endeavors, many companies and individuals have their eyes on ways to be more sustainable. One effective and easy thing to do is to use RPET bags. These reusable bags reduce plastic waste by a huge amount each year, and they are saving even more materials all the time as more people begin to use them.
Material
RPET bags are made from recycled polyester which is turned into a sturdy fabric. The &#;PET&#; in RPET represents a common type of plastic found most commonly in plastic bottles; the &#;R&#; stands for &#;recycled&#;. The material is strong, porous, and durable. RPET is the material that is chosen most often for reusable bags because it is easiest to process, so it uses the least energy to generate bags from the recycled materials.
Pros and Cons
The good side of RPET bags is that they are very durable. The material is hard to tear, even under heavier loads. Over time, the fibers don't get much weaker. The bags are also waterproof. Also, they are more comfortable to carry than regular plastic bags and many other reusable bags, because the material is quite soft. The downside of these bags would be that they are somewhat hard to clean. Once something is spilled on the bag, it's hard to remove the stain completely.
Costs
Normally, RPET shopping bags are purchased in bulk. The cost varies greatly between suppliers, based on the quality of the products desired. For a purchase of or more bags, one can expect to pay $0.50 on the low end and $5 a piece for bags that are customized and have sleek designs. Shipping cost is generally not included in the purchase price, so determine the costs of shipping before committing to a purchase.
Distributors
The best resource for buying reusable bags is the internet. A variety of providers sell the bags, each with different quality and pricing for their products. One thing to note when choosing a distributor is the shipping costs. A product might seem to be selling at a value price, but once you add on the shipping cost, the price becomes equal or higher than other products on the market.
Conclusion
In summary, RPET bags are a smart choice for individuals and companies. The cost of the bags is minimal compared to the costs, both economic and environmental, of continuously using single-use plastic bags. It would be ideal if each person had an RPET bag to use on a daily basis. Though this is not yet the case, when even a few new people begin to use an RPET bag, it starts to make a big impact on the environment.
