Plastics Industry Welcomes CSIR Report Confirming Their Bags Have Smallest Enviro Footprint

Plastic Carrier Bags Tread Lightly On Mother Earth

Identifying the "best" bag in the South African context

The study was funded by the Department of Science and Innovation (DSI) and aimed to identify which bag is “best” in the South African context. It assessed sixteen different types of carrier bags - including the standard single-use, 24 micron HDPE bags, as well as a number of reusable and biodegradable alternatives.

Twenty-one environmental and socio-economic indicators were used to assess the life cycle of each bag, including water use, land use, global warming, the impacts of pollution, impact on employment and the affordability for consumers.

According to Plastics SA’s Executive Director, Anton Hanekom, the local study confirmed the findings of similar studies which have been conducted elsewhere in the world, such as a recent analysis by Denmark's Ministry of Environment & Food which found that cotton bags have to be re-used 7,100 times in order to have the same cumulative environmental impact as using standard plastic bags which are easy to produce, require very little energy and produce very little carbon dioxide emissions.

Locally produced plastic bags ideally suited to be reused

"What is particularly welcoming, is that the CSIR study assessed a broad range of environmental and socio-economic indicators that are unique to our South African context. It has confirmed our message that our locally produced, plastic bags (ranging from 24 microns right up to 70 microns) are ideally suited to be reused and should therefore not be considered a single-use plastic," Hanekom said.

The majority of the plastic carrier bags used in most African, American, Asian and European markets, range between 12 and 17 microns in thickness. In South Africa, however, retail plastic bags are regulated to be a minimum of 30micron, plus or minus a 20% variance. Although the CSIR study focused primarily on testing the plastic carrier bags of that were between 30 and 70 microns, it confirmed that plastic carrier bags performed best overall – provided that they are reused.

Making plastic bags recyclable to be part of the circular economy

The South African plastics industry reached a major milestone in 2018 when the local bag manufacturers improved the recyclability of their bags by reducing the filler content. At the same time, South African retailers agreed to change their carrier bags from virgin, to include post-consumer recycled content.

This move created a much-needed and substantial market for post-consumer recycled material. It was hailed as an important breakthrough for the industry and its efforts to address the issue of single-use plastics polluting the environment. By ensuring that plastic carrier bags become part of a circular economy, a win-win situation has been created for the environment and for the industry.

"Our retail plastic bags are unique and unquestionably reusable for its primary function, namely shopping, but also have a multitude of secondary uses in South African households. Moreover, it is important to highlight that our locally produced carrier bags are recyclable and a large percentage of them even have recycled content..." - Anton Hanekom, Plastics SA

Locally produced plastic bags boost the economy and create jobs

"The manufacturing and recycling of plastic carrier bags not only help to create employment to more than 60 000 South Africans, but also contribute vast sums of money to state funds.

Plastic bags are still the only packaging item for which an environmental tax is levied. Since the beginning of April this year, plastic bag levies have increased to 25 cents, which is expected to generate more than R250 million for the state coffers. As an industry we are appealing to the Government to ensure that at least some of these funds are used to help us boost recycling and grow a circular economy," Hanekom appeals.

Plastic bag manufacturers respond

"Plastic bags were never intended to only be used once. In fact, they were invented with the purpose of saving the planet" - Phillip Abelheim, CEO: Transpaco Limited

Weighing in on the matter on behalf of plastic bag manufacturers, Phillip Abelheim, Chief Executive Officer of Transpaco Limited and one of South Africa’s biggest manufacturers of plastic bags, said the latest research findings were encouraging to a manufacturing sector that has been until recently, been on the receiving end of harsh criticism.

"Plastic bags were never intended to only be used once. In fact, they were invented in 1959 by Swedish engineer Sten Gustaf Thulin with the purpose of saving the planet. Because they were significantly stronger than paper bags, he created these bags to help save the forests by being used over and over again. To Thulin, who was known for always carrying a plastic bag folded in his pocket, the idea that people only use their bags once and then throw them away, would be bizarre and completely go against what they were originally designed to do," - Abelheim

Concluding remarks:

"We believe that plastic carrier bags and plastic items in general have an important role to play in our modern society. The recent worldwide COVID-19 pandemic has once again proven that the world relies on plastics to help prevent the spreading of diseases, protect food and to keep us healthyPlastic products are strong and versatile and offer us convenience at a low price. The ongoing challenge lies in preventing this wonder material from ending up in the environment after it has been used, and making sure that it is properly discarded so that it can be recycled into a multitude of different and new products," - Hanekom concludes.
