Executive Summary
“Green Pipe” is a product of Recycled Plastic Technology Ltd., Australia. It is formed using a newly developed manufacturing technique and made out of 100% recycled / kerbside collection ofHDPE containers (mainly milk bottles).
Presently it is popular in both rural and urban applicationsas a non-pressure drainage pipe.
To expand the range of applications of the Green pipe, material properties and design parametersneed to be established.
This project aims to establish these properties and parameters byinvestigating the physical characteristics of the Green Pipe, and comparing them with those of pipes made from virgin material.
This report presents results from testing the original and improved versions of the Green Pipe. This summary however only shows the properties of the New Green Pipe, which was introduced to the market in 2004 as a standard upgrade.
The New Green Pipe showed better ductility compared to the original Green Pipe. The initial ring bending modulus (Eb) for the New Green Pipe is slightly higher than that of PE 80. When compared with the long-term ring bending modulus (EbL), the 50-year value is comparable to that of PE 80.
