Recycling across the whole school

Year 5 Environment Ministers Maddie and Juliette have brought the Greenbatch recycling programme to the Junior School. They are collecting clean number 1 and number 2 plastic bottles which will be turned into 3D printing cartridges. There will be two bins outside the library for families and students to drop their clean bottles into and help save the environment.

Their initiative means there’s now an opportunity to recycle PET and HDPE plastic containers (clean, no lids, not crushed) across the whole school.

The plastics are delivered to Greenbatch, the state’s only recycler of plastics, who turn them into 3D print filament. Earlier in Term Three, a class of Year 6s got to see how it all happens with a visit to the recycling operation in Claremont.

Students were given an introduction in the dedicated Makerspace area at Greenbatch and then split into groups to experience the different processes in the recycling operation. The sorting area was a hive of activity, and students were very appreciative of how clean our collected plastic was – great work Helena community! They also saw how some of the collected plastic from other sites could not be recycled as it was not clean and unfortunately ended up in landfill. Students also helped with sorting the plastic lids into the shredder ready for further processing. Many thousands of the shredded lids are bound for mixing into asphalt for parks and playgrounds.

In the Makerspace area, students saw how the shredded HDPE plastic can be heated and processed into new products and created their own colourful coaster from the plastic.

Greenbatch is only post-consumer plastic processing plant in WA and is working with WA schools to collect PET and HDPE plastics with the aim of recycling the plastics into 3D Printer filament and fabrics. For more information on Greenbatch, visit
