A New Way To Make PlasticPosted on September 11, 2015 by DrRossH in Plastic Waste News
In wastewater treatment plants in Belgium, the Netherlands, and Denmark, something unusual has been, and continues to happen. Anoxkaldnes, a subsidiary of Veolia, is running pilot prototyping for the production and recovery of Polyhydroxyalkanoates (PHA) – an intermediate material used to produce bioplastics.
Simultaneously, there is also growing support for international action to reduce CO2 emissions ahead of the COP21 summit in Paris in November. The manufacturing of plastics is a CO2 emitting process with estimates ranging from 100 million to 500 million in terms of tonnes per year emitted from production processes in the U.S. alone. That means that the CO2 in plastics production could be equal to as much as 45% of the total annual emissions from motor vehicles in the U.S. If fees or the pricing structure of carbon is changed, then the impacts will be felt by producers of raw petro-based plastics.
Looking through the lens of a circular economy, it is clear that the system of petro-based plastics is not operating effectively in terms of its negative effects and its over-reliance upon finite resources. It’s a system that is facing increasing challenges with limitations that are gradually being acknowledged.
