PET Recycling (Polyethylene terephthalate)

Your recycling is collected by the recycling truck. It is sorted at the materials recovery facility at Smithfield. PET bottles are hand sorted from the conveyer belt and squashed and baled.

The bottles are granulated into flakes and washed. This process removes glue, grime and labels. PET is heavier than water - it sinks to the bottom, lids and labels float. The most common contaminants are straws and lids. Always remember to remove your straws and the lids from the bottles before putting them in your recycling bin.

Granulated flakes are inspected for quality. If approved the clean flakes enter a purification process before being extruded into pellets A vacuum draws blended resin from virgin and recycled pellets into the dryer. After several hours the blended resin is injected into the preform mould and clamped. Resulting in the production of the embryonic bottle- The preform.

The blow moulding machine creates the final shape of the bottle through the simultaneous blowing and stretching of the preheated preforms.

Your recycled PET not only makes new bottles but can be spun into material used for clothes, pillows, dooners, ski suits etc. This type of material is called ECO FLEECE. Other common uses for recycles PET bottles include the manufacture of paintbrush handles, plastic strapping, tennis balls, bathtubs, boat hulls, car parts and shower curtains. In the Unites States- approximately 35% of synthetic carpeting contains some proportion of PET.

HDPE (High density polyethelene) 2

Lots of different types of bottles are made out of HDPE. Milk bottles are the most common- but often shampoo, detergent, and fabric softener bottles are made from HDPE. HDPE is made from natural gas that is mined from Bass Straight.

The process of recycling HDPE is very similar to the PET process. The bottles are cut down into smaller pieces, washed, granulated and them moulded into new products.

Recycled HDPE can make many amazing products such as:

  • Wheelie bins

  • Stormwater pipes

  • Strong pallets and crates

  • Detergent and oil bottles

  • Garden edging

  • Benches chairs and outdoor furniture

  • Bird baths

  • Compost bins and worm farms

  • Letterboxes

  • Wheelbarrows

  • Bus shelter panels

  • Speed bumps

  • Plant pots.
