It is extraordinary how many politicians who are concerned about plastic persisting in the open environment are choosing “compostable” plastic, tested to ASTM D6400, instead of plastic tested to ASTM D6954 to biodegrade in the open environment, especially where there are no industrial composting facilities in the country or locality concerned. Perhaps they are also unaware that “compostable” plastic is not recyclable and does not convert into compost, but converts instead into CO2.
Now it seems that the industrial composters don’t want “compostable” plastic.
There is a really important report from the State of Oregon, USA https://bioplasticsnews.com/wp-content/uploads/2019/04/Oregon-composters-dont-want-Compostable-Packagine.pdf in which the industrial composters of Oregon give nine specific reasons and say “Compostable” packaging and service-ware items have been on the rise for the past decade and they are increasingly ending up in our facilities.
These materials compromise our composting programs and limit many of the environmental benefits of successful composting….. Not only do compostable products often cost more to purchase, they also drive up the costs to operate our facilities and impede our ability to sell finished compost. Compostable packaging is promoted as a means of achieving “zero waste” goals but it burdens composters (and recyclers) with materials that harm our ability to efficiently process recovered materials.”
