The decision by the company is part of an effort to reduce CO2 emissions, it said in a statement.
Much of Arla’s packaging – including the one-litre organic milk cartons – is already produced from renewable materials such as plants and trees.
By dropping the plastic caps, the company says it can reduce the CO2 footprint of each carton by 30 percent.
Consumers buy 74 million cartons a year of the product from which the plastic packaging component is set to be removed. Each individual plastic cap is responsible for emissions of 10 grams of CO2, according to Arla.
As such the emissions saving on the caps could reach 740 tonnes of carbon dioxide annually. The figures are based on emissions measured during the period October 2019 to September 2020.
Arla has previously declared its ambition to achieve CO2-neutral operations by 2050.
“We and our farmers have an ambitious target of becoming CO2 neutral, and we are reducing are emissions on an ongoing basis,” Arla Denmark country director Helle Müller Petersen said in the statement.
“Part of that work is to reduce the CO2 emissions from our packaging, for example by reducing the use of plastic,” Petersen added.
“It’s therefore an active choice for us to remove the screw top from the organic milk,” she said.
