The Fallacy of Biodegradable Graphic Materials
We often hear from clients of the need for us to print graphics on "biodegradable" materials. In fact one of our Vancouver-based graphic competitors has information on their website showing a scientific study that highlights the biodegradable properties of their banner material. I spend a great deal of my time educating purchasers about the "green washing" that is going on in our industry. A really fascinating snippet from "The Garbage Project" by W.L. Rathje highlights the fallacy of Biodegradable materials:
"Another set of findings from the Garbage Project's digs underscores, especially for the public, the need to recycle and compost materials to keep them out of refuse. Many people have assumed that organic materials, such as newspapers, simply biodegrade in landfills. The recovery of 2,425 datable, readable newspapers from landfill excavations dramatically changed that view, especially since the relative proportion of newspapers varied little between materials deposited anywhere from five to forty years before exhumation and in environments which received anywhere between 11 and 80 inches of rain a year. The one exception was Fresh Kills Landfill that was started in 1948 when refuse was deposited in a tidal swamp on Staten Island with no liner. Under these conditions, refuse layers from the late 1940s and from the 1950s are now largely devoid of organic materials, including newspapers."
THE GARBAGE PROJECT & "THE ARCHAEOLOGY OF US" by W.L.Rathje
The focus of manufacturers should be on recycling of materials and not trying to convince clients that they will biodegrade in a landfill. Clearly, if newspapers did not degrade anywhere from five to fourty years, how can we expect graphic printing materials to do so quicker. The Portables is working on solutions that are based on scientific research that try and keep materials out of the landfill. I will keep you informed as to how we are progressing.
