Are bags made from recycled plastic bottles possible?

Yes it is possible and that is what KÖSS offers you with its bags made in Rpet!

But what is rPET?

First of all, you have to know what is PET. PET is the abbreviation of the terms polyethylene terephthalate . It is by far the most common type of plastic. It is a fully recyclable plastic .

For its part, rPET, short for "recycled polyethylene terephthalate", is a material made entirely from recycled PET . It offers many ecological advantages, in particular the possibility of creating a complete recycling circuit. In fact, rPET can be 100% recycled, making it a sustainable choice for environmentally conscious companies.

What are the benefits of rPET?

  • To manufacture rPET, no new raw materials are used . Post-consumer plastic is thus given a second life. In addition, it reduces the use of raw materials such as oil, necessary for the production of PET plastic.
  • Making this material significantly reduces the amount of waste that ends up in landfills, nature and the oceans.
  • Recycled polyester is almost identical to virgin polyester in terms of quality , but its production requires 59 percent less energy compared to virgin polyester, according to a 2017 study by the Federal Office for the Environment (FOEN).
  • Manufacturing rPET involves lower CO² emissions than if other manufacturing methods were used. Greenhouse gas emissions are therefore reduced , which limits the impact on climate change.
  • Recycling PET also reduces production costs , making rPET more affordable and more competitive than virgin PET.

Some numbers

  • Recycling PET allows energy savings of up to 60%, compared to producing PET from virgin raw materials.
  • With 42 plastic bottles, we can produce one kilo of recycled pet.
  • One ton of recycled PET saves 1.2 tons of oil and 5 soda bottles


Although an ideal world aims for the complete disappearance of plastic, eliminating the need to produce new plastic is today the difference proposed by KÖSS and which gives a second life to this material which would otherwise end up in landfills or in the ocean.
