I read the latest Green Guides Summary Proposal document posted here: http://www.eenews.net/assets/2010/10/06/document_gw_02.pdf. I found it generally simple and clear. HOWEVER one glaring green concept was missing: "Reusable". Reusable products are much more green than recyclable. One argument against reusable is that it might not be reused. But the same argument goes for recyclable because it might not be recycled. Furthermore reusable products do not require reprocessing and are therefore more green than recyclable products. My company, InnerSpace, is proud to offer modular wall panels that are reusable. Construction waste is estimated to be nearly 30% of all US landfill. Reusable wall systems can significantly reduce this. But too often reusability is left out of the green discussion. For example, the LEED system does not recognize this environmental contribution. I feel it is very important that reusability become a significant part of the green movement. Including this heading in your Green Guides would help considerably and leaving "Reusable" out of it would be a terrible omission.
