PAPER, NATURAL OR NON-WOVEN BAGS – WHICH IS BETTER FOR OUR ENVIRONMENT?
Countries around the world have joined the effort to curb plastic use, especially single-use plastic bags. Most Australian states have implemented the plastic bag ban, which has resulted in billions of light-weight plastic bags being kept from landfill and polluting the environment. Upwards of 5000 tonnes of the problematic plastics have been saved by one grocery chain alone.
With these bags out of action, the humble tote bag has risen significantly in the promotional product space. Companies have recognised the need for durable and reusable bags, but have been torn between a traditional paper bag, a natural fibre bag made from cotton, jute or bamboo, or a hardy non-woven polypropylene bag.
So which is better?
Since the plastic bag ban, many have demanded we return to the way things were done in the past. The image springs to mind of a shopper coming home with their arms filled with paper grocery bags, a baguette sticking out of one and celery out of another.
Modern consumers have questioned the durability of these bags however, acknowledging how a blowout would send those groceries all across the floor. Luckily, paper bags aren’t all flimsy and handle-less. Today’s promotional paper bags are made of tough, 120gsm+ kraft paper with flat or twisted paper, or rope handles.
In terms of the environment, we all know how paper is made; from raw wood, pulped and pressed. Because of their natural source, paper bags are easily recycled and break down quickly in landfill. However, the production process requires water and energy, more water and energy than plastic. Paper bags are also weightier than plastic and so require more energy to transport.
The production of paper bags, even if the wood is sourced responsibly, has a greater environmental impact than plastic. However, paper bags do not threaten the environment when they are discarded.
Cotton, jute and bamboo bags are the next favourite plastic alternative for the same reason as paper bags. They’re made from natural, responsibly sourced fibre that is biodegradable. A natural fibre bag is easily washable and will hold just as much, if not more than the single-use plastic bags of the past. It has been said that they can hold upwards of 10kgs!
Between cotton, jute and bamboo, cotton is the least environmentally friendly because of the water and pesticides used in its production. Reports state that to neutralise its environmental footprint, a cotton tote bag would need to be used 7,100 times.
Jute is the unrefined version of hessian and is known as the ‘Golden Fibre.’ It requires very little water, pesticides and land for its production. Its long and strong fibres means a jute tote bag will outlast others, decreasing its footprint further with each use.
Because bamboo is a fast-growing plant, it is an easily sustainable resource, perfect for consumable products like bags. Like jute, bamboo is naturally bacteria resistant and does not require pesticides in its production. It also uses very little water to grow.
A non-woven bag is made from polypropylene and, because it is not woven, has the same feel as a canvas bag. These are the green and red bags available at grocery stores for 99 cents. Non-woven bags can be made from recycled plastic, but need to be reused 11 times to nullify the emissions produced by their manufacture.
Non-woven bags are machine-washable and durable but almost all will take over 1,000 years to breakdown in landfill. The good news is, there is now an independently tested, biodegradable non-woven bag available that is chemically treated during the manufacturing process to become *biodegradable in microbe rich municipal landfills (*ASTMD5511). You can access the test and results here https://www.astm.org/Standards/D5511.htm.
So Which Is Better For The Environment?
This is a question that has been asked since well before the plastic bag bans. Concern for the Earth has turned consumer focus to the way they use plastic and its effects on the environment.
While natural products seem the logical choice for ‘most environmentally friendly’, they aren’t always. The resources used in growing and the manufacture of natural products can have more of an impact that those needed for the non-woven polypropylene. However, in terms of what we leave behind, natural products will degrade once discarded, while plastics can be recycled but will not breakdown in our lifetime.
To choose which bag is best, you have to decide what your priority is. Is it reducing your carbon footprint? Or is it protecting our ecosystems and wildlife?
