| Petrecycle has installed a pilot plant at Brooklyn, about 20km away from the Melbourne CBD. The objective of the pilot plant is to enable a comprehensive demonstration and studies of the Renew process for polyester recycle. |
 |
| Process Summary |
The Renew Process consists of the following key steps:
|
 |
|
Low temperature solid phase Stage 1 glycolysis of PET flake to enable embrittlement and removal of key contaminants in the post consumer bottle waste |
|
 |
|
Low temperature Stage 2 melt phase glycolysis of PET flake to enable complete depolymerisation of PET in presence of excess glycol, yielding a free flowing low viscosity polymer solution in glycol |
|
 |
|
Addition of proprietary additives to the low viscosity polymer solution to enable adsorption of colour
Depth filtration of the solution to remove additives, colour, PVC and all other inert contaminants from the polymer solution |
|
| The pilot plant is capable of demonstration of all of the above 4 steps. The pictures below serve to depict the facilities available at Brooklyn in Melbourne. All the above steps are covered by global patents. |
