Back in 2002 I was doing an environmental masters degree at The Centre of Alternative Technology in Machynlleth, Wales. We had to write a lot of essays but could basically choose our own essay title as long as it was relevant to the module. For the materials unit I decided to carry out a Life Cycle Analysis of copper pipe v plastic pipe, in this case specifically HEP2O (polybutylene)which was becoming more and more ubiquitous on site. I was not a fan of HEP2O; I loved copper and wanted to continue to use it. So what better way than to prove that copper was environmentally superior to HEP??
So I did all the research and the answer was…
But why spoil a good mystery by revealing the answer so soon? I had lost the word version of the essay years ago, but a few weeks ago found a hard copy of it. Finally! So I have scanned it and you can read it here: An LCA of copper pipe v hep2o
As I said at the beginning I did all the research in 2002, so please bear that in mind when reading it. At the same time I expect my conclusion would still be similar.
