From the EU Science for Environment Policy website, an article titled Improved sorting strategies needed in recycled wood waste (RWW) . The researchers believe that achieving a high rate of recycling of this material with the aim of protecting finite resources can lead to unwanted pollution problems if material is improperly sorted. They recommend that a pollution perspective is a necessary complement to the focus on recycling. In the absence of this, market forces encourage consumers of RWW, such as district heating schemes, to apply separation and quality requirements less than rigorously.
I guess that I am looking to be one of those consumers of RWW. I’m also acting under market forces, but probably not in the way that the researchers think. Looks like I have to find the Waste Management journal. Something like that will surely be online :)
