One of the leading Austrian consulting companies in the field of sustainable development and environmental management, Denkstatt GmbH, has just published a study that mirrors our calculations on the relative environmental impact of recycled PET compared to virgin material.
Each trumpets the “excellent,” “surprising,” “striking” and “better than expected” carbon footprint of recycled PET that “was calculated in accordance with ISO 14044, starting with the collection and sorting of used PET bottles, covering transportation to the recycling plant in Wöllersdorf, through to washing, processing and granulating, and based on the mass and energy balance (electricity and gas consumption) for 2016 at the Austrian recycling plant.”
The CO2 emissions of rPET were found to be 79 percent lower than for new PET material. As plant manager Peter Fröschel said, “‘The savings for a single kilogram of rPET are enough to power a 13-watt bulb continuously for twenty days in the Austrian power mix.”
These savings are in line with the calculation from our operations, where half litre bottles made of recycled PET in Canada require 78% less energy & produce 78% less emissions than the average for packaged beverages and in the United States 76% less energy & 66% less emissions.
