Resin Identification Coding System is a set of symbols placed on plastics to identify the polymer type.
It was developed by the Society of the Plastics Industry (SPI) in 1988.
Primary purpose of the codes is to allow efficient separation of different polymer types for recycling .
The symbols used in the code consist of arrows that cycle clockwise to form a rounded triangle and enclosing a number, often with an acronym representing the plastic below the triangle.
When the number is omitted, the symbol is known as the universal Recycling Symbol , indicating generic recyclable materials. In this case, other text and labels are used to indicate the material(s) used.
The number not indicate how hard the item is to recycle , nor how often the plastic was recycled . It is an arbitrary number and has no other meaning aside from identifying the specific plastic .

PET BOTTLE & POLYESTER
Most synthetic fibers (approximately 70%) are made from polyester, and the polyester most often used in textiles is polyethylene terephthalate (PET) .
The majority of the world’s PET production – about 60% – is used to make fibers for textiles; about 30% is used to make bottles.
It’s estimated that it takes about 104 million barrels of oil for PET production each year – that’s 70 million barrels just to produce the virgin polyester used in fabrics.
The reason recycled polyester (often written rPET) is considered a green option in textiles today is twofold, and the argument goes like this:
Saving energy (33% to 53% less energy than produce from virgin)
Estimate at 54.6% fewer CO2 emissions
Keeping bottles and other plastics out of the landfills.
Fun Facts About PET
First PET bottle was recycled in 1977
FACTS about PET:
Recycling 1 ton of PET bottles saves 7.4 cubic yards of landfill space
It takes 5 recycled two-liter PET bottles to make one square foot of carpet.
PET bottles and containers are actually a form of polyester, which is why it is so easy to recycle bottles into T-shirts, sweaters and socks.
It takes 35 two-liter recycled PET bottles to make the soft filling inside a sleeping bag, called “fiberfill.”
Plastic makes up 8% of our trash by weight, but is 24% of the volume

Government – Institutes….
Target for the “BTB” Recycling
No differences for the consumer
Performance of the bottle
Colour, black spots, taste …..
No risk for the consumer and the industry
No differences for the preform production
Parameters for end product
I V , AA, Colour , pellet, filtration, ....
Normally not tasted/approved by the government
Chemical Cleaness - Decontamination
Normally done only with Challenge and Migration test
Depends only on the cleaning effect of the system
Required from preform producer
IV increase - depending on beverage
Normally yes because in the long term “closed loop” can`t work
Normally yes, because of black spots request, metal, glas, silicon issue..
Normally yes, otherwise invest for prefrom producer requested
Request for Chemical Cleanness
Absolute no risk for consumer – no taste change….
“ Super cleaning process” has to show the decontamination by a Challenge Test
The migration has to be inside the legislation
