What I learned from Tammy Coe, associate of Sustainable Forestry/Smartwood, is that there is a third party certification process that printers and paper manufacturers go through to obtain the sustainable paper seal of approval. Many of these companies have strived to obtain this seal after a three year certification process. Kirkwood Printing is one of them. This assures customers that the wood and paper products they are purchasing come from forests managed to conserve biodiversity and support local communities.
