The purpose of having a recycling code on plastics is so that they can be tracked. Different companies want their plastics back to make more bottles for example.

You could get your plastics recycled (eg, plastic bottles) by putting them in the recycling box if you have one. Then your plastics will go to the recycling place!

European Life cycle database is the database that should be used for plastics recycling in EU. There is also a law for the recycling industry.
There are different recycling numbers on different plastics because all plastics are different. Many recycling facilities need to separate these types of plastics because they all melt at different temperatures and can be reused for different things.

You can separate plastics by color to make it easier for recycling companies. You can also separate it by the types of plastics.

It is a type of plastic. What is important is what type of plastic. See this website here on recycling plastic: http://www.ides.com/resources/plastic-recycling-codes.asp Read the different codes there.

Recycling Plastics actually is not good for the enviorment. It may come as a shock, but more money is wasted and more pollution is created by recycling plastic than it would be if it was created new. There is actually more than enough materials to create new plastic in the world at the moment, so recycling plastics is a really long way from becoming nessecary.
Synthetic polymers have recycling numbers to indicate the type of plastic they are made of and help with sorting and recycling processes. The numbering system, known as resin identification codes, was introduced to standardize recycling efforts and determine the appropriate recycling method for each polymer. This allows for efficient sorting and recycling of different types of plastics, reducing waste and promoting circular economy practices.
