In 2017, Lower Hutt business Flight Plastics opened New Zealand’s first PET plastic wash and recycling plant. Flight Plastics turns the recycled plastic into RPET flakes and uses the flakes to make new food-grade packaging. In 2021 the Pact Group acquired Flight Plastics and continues it's work under the name Pact Packaging.
In this activity, students use Hub resources to design and operate their own PET plastic wash and recycling plant, loosely based on the Pact Packaging process.
By the end of this activity, students should be able to:
- use written and visual resources to gain information about the plastic recycling process
- discuss some of the steps involved in processing/recycling a PET plastic item
- place the steps in the order they are likely to happen
- design a model of the recycling process using familiar, everyday materials
- discuss how the model represents the actual steps in the recycling process
- consider how recycling fits into the use and reuse of plastics.

Nature of science
Hands-on experiences, like the model recycling process in this activity, support the Investigating in science strand. Engaging students in a wide variety of investigative processes helps to debunk the myth of there being one ‘scientific method’.
