PET Bottle recycling business
recycling of pet bottle
PET plastic reccyling , mostly we see is PET bottle recycling. Post-consumer polyethylene terephthalate (PET or PETE) containers are sorted into different color fractions and baled for onward sale. PET recyclers further sort the baled bottles and they are washed and flaked (or flaked and then washed). Non-PET fractions such as caps and labels are removed during this process. The clean flake is dried. Further treatment can take place e.g. melt filtering and pelletizing or various treatments to produce food-contact-approved recycled PET (RPET).
RPET has been widely used to produce polyester fibres.This sorted post-consumer PET waste is crushed, chopped into flakes, pressed into bales, and offered for sale.
One use for this recycled PET is to create fabrics to be used in the clothing industry. The fabrics are created by spinning the PET flakes into thread and yarn.This is done just as easily as creating polyester from brand new PET.The recycled PET thread or yarn can be used either alone or together with other fibers to create a very wide variety of fabrics. Traditionally these fabrics are used to create strong, durable, rough products, such as jackets, coats, shoes, bags, hats, and accessories since they are usually too rough for direct skin contact and can cause irritation. However, these types of fabrics have become more popular as a result of the public’s growing awareness of environmental issues. Numerous fabric and clothing manufacturers have capitalized on this trend.
Other major outlets for RPET are new containers (food-contact or non-food-contact) produced either by (injection stretch blow) moulding into bottles and jars or by thermoforming APET sheet to produce clamshells, blister packs and collation trays. These applications used 46% of all RPET produced in Europe in 2010. Other applications, such as strapping tape, injection-moulded engineering components and building materials, account for 13% of the 2010 RPET production.
In the United States, the recycling rate for PET packaging was 31% in 2013, according to a report from The National Association for PET Container Resources (NAPCOR) and The Association of Postconsumer Plastic Recyclers (APR). A total of 1.798 billion pounds was collected and 475 million pounds of recycled PET used out of a total of 5.764 billion pounds of PET bottles.
Bottles made of polyethylene terephthalate (PET, sometimes PETE) can be used to make lower grade products, such as carpets.[citation needed] To make a food grade plastic, the bottles need to be hydrolysed down to monomers, which are purified and then re-polymerised to make new PET. In many countries, PET plastics are coded with the resin identification code number “1” inside the universal recycling symbol, usually located on the bottom of the container.
PET is used as a raw material for making packaging materials such as bottles and containers for packaging a wide range of food products and other consumer goods. Examples include soft drinks, alcoholic beverages, detergents, cosmetics, pharmaceutical products and edible oils. PET is one of the most common consumer plastics used.Polyethylene terephthalate can also be used as the main material in making water-resistant paper.
When the PET bottles are returned to an authorized redemption center, or to the original seller in some jurisdictions, the deposit is partly or fully refunded to the redeemer. In both cases the collected post-consumer PET is taken to recycling centres known as materials recovery facilities (MRF) where it is sorted and separated from other materials such as metal, objects made out of other rigid plastics such as PVC, HDPE, polypropylene, flexible plastics such as those used for bags (generally low density polyethylene), drink cartons, glass, and anything else which is not made out of PET.
Post-consumer PET is often sorted into different colour fractions: transparent or uncoloured PET, blue and green coloured PET, and the remainder into a mixed colours fraction. The emergence of new colours (such as amber for plastic beer bottles) further complicates the sorting process for the recycling industry.
The further treatment process includes crushing, washing, separating and drying. Recycling companies further treat the post-consumer PET by shredding the material into small fragments. These fragments still contain residues of the original content, shredded paper labels and plastic caps. These are removed by plastic granulation, resulting in pure PET fragments, or “PET flakes”. PET flakes are used as the raw material for a range of products that would otherwise be made of polyester. Examples include polyester fibres (a base material for the production of clothing, pillows, carpets, etc.), polyester sheets, strapping, or back into PET bottles.
