What’s the best material for shopping bags: paper, plastic, or jute?

Few goods receive more negative attention than plastic shopping bags. They are created from oil, do not deteriorate, and are widely circulated. Plastic bags clutter the landscape, entangling birds and suffocating turtles.

Paper bags, on the other hand, are made of natural materials and are biodegradable. Surely, it’s preferable to use paper, right? And, come to think of it, why not use jute bags? It’s a renewable material that can be turned into reusable shopping bags. That has to be the greatest option, right?

An eco-friendly bag’s purpose is to hold goods while leaving a small ecological footprint. So, one of the easiest methods to analyze these materials from an ecological standpoint is to utilize a carbon footprint (CO2-equivalent) as a metric. Let’s look at plastic, paper, and jute bags with roughly the same capacity using this value.

Shopping Bags That Are Eco-Friendly

Here’s a list of the shopping bags we’ll be comparing in terms of their environmental impact.

Polyethylene Bags: Assume “bag 1” is a standard one-use supermarket container. It weighs roughly 7 grammes and is made of polyethylene (PE). Consider “bag 2,” which is also composed of PE but is three times heavier. Bag 2 includes a designer graphic as well. It’s appealing, strong, and far too nice to throw away – at least not right away.

Paper Bags: Assume “bag 3” is made of paper. Paper bags imply environmental awareness – a purposeful avoidance of plastic. They are beneficial to a company’s image. They do, however, have more mass — almost seven times that of bag 1.

Reusable Bags: Assume that “bag 4” is a reusable bag. It is strong and long-lasting. It has the appearance and feel of a woven fabric. However, appearances can be deceiving because it is made of polypropylene (PP). The green hue and emblem imply that it is environmentally friendly, but is it?

Jute/Cotton Bags: Finally, consider that “bag 5” is the preferred style of minimalists and conservationists. The bag is unobtrusive, subtle, and unnoticed. Those who own one can rest easy knowing that it is constructed of juco, a 75 percent jute and 25 percent cotton blend. This bag, on the other hand, consumes a lot of material – 36 times more than bag 1.

Shopping Bags’ Ecological Material Factors

The combatants have been chosen. Let’s see how they compare now.

The findings indicate how difficult it is to select the appropriate materials for reusable bags. Eco-bags frequently travel into a realm that isn’t about containment; it’s about company and self-image. However, we are interested in eco-analysis rather than psychoanalysis.

So, consider this: if bag 1 is only used once, how many times do you need to use the reusable shopping bags to have a lower carbon footprint?

The fourth column in the table shows the carbon footprints of PE, PP, paper, and juco per kilogramme. The fifth column is calculated by multiplying these numbers by the weight of 100 bags. You can normalize the data in column 5 to create column 6 by using the ecological footprint of 100 plastic bags (bag 1). Column 6 shows how many times a reusable bag must be used in order to have a smaller carbon footprint than bag 1.

Which Shopping Bag is the Most Eco-Friendly?

The short response is that everyone must make their own decisions. Which is the best bag? It all boils down to your behaviours.

Do you think you’d reuse a paper bag five times? They rip quickly and are damp when it rains, which is unlikely. If you don’t, plastic bags (bag 1) outperform paper bags in terms of carbon footprint (bag 3).

What about reusable shopping bags? Do you think you’d use bag 4 more than 17 times? I have a comparable one that has already been used more than that — therefore it’s a keeper for me. However, you may have a stash of these bags lying around your house accumulating dust. They would likewise lose in this instance to the plastic bags.

Finally, bag 5 must be used 30 times before it has the same carbon impact as bag 1. This isn’t impossible, as long as nothing leaks or breaks.

So, from a carbon standpoint, single-use bags are not always bad – it all depends on how diligent you are about reusing any other bag. The main issue with plastic is that its insignificant value entices people to throw it away without a second thought. Plastic bags have a lengthy life, which causes them to amass on land and in water, where they deface the landscape and endanger species.
