TGP is made from 100% recycled plastic (high density polyethylene) including a QA requirement of a minimum of 95% food grade containers (almost entirely from household collected post consumer milk & orange juice grade bottles)
Whilst comparing the embodied energy of The Green Pipe to that of its competitors, we found that the results were better than our own expectations, all research results indicated the embodied energy of TGP to be between only 7% & 25% of that of the competitors.
The green Pipe’s embodied energy has been calculated at 7.91 Mj/kg including the collection of raw materials & the complete manufacturing process
| Product/material | (MJ/kg) | MJ/mtr – 375mm diameter |
| Cement | 7.8 | 928 - Approx |
| The Green Pipe | 7.9 | 99 |
| Steel | 32 | |
| Polypropylene | 64 | |
| PVC | 70 | |
| HDPE & LDPE (virgin polyethylene) | 103 |
These figures do not include freight from our manufacturing plant in Moama to site however, the ability of TGP to be ‘nested’ during transportation further enhances TGP’s comparative embodied energy figures.
Whilst HDPE is itself non-degradable underground TGP raw materials sources ensure that the pipe will not leach toxic products into the surrounding soil. No ‘Drum Muster’ products are used in manufacture.
Since its development in 1999 TGP have converted over 100 billion 2 litre milk bottles. Most recently the West Gate Freeway Alliance used the equivalent of 67,200 x 2 litre plastic milk and orange juice grade bottles that would’ve otherwise been landfill.
