No, You Do Not Have To Reuse A Cloth Bag 171 Times to Equal a Plastic Bag
Some studies have shown that in order for a cloth bag to be as environmentally effective as a single-use plastic bag, the cloth bag would have to be used 171 times or more. But overall, thee studies are missing a lot of factors.
The two main studies I will be focusing on is a UK report from 2011, and a danish report from 2018. Both of these reports have a lot of good information in them, but they make a lot of assumptions that don’t seem to be based on fact, or else ignores potential alternatives.
When people spout this statistic, they make it seem like carbon emissions are the only thing that one has to deal with when it comes to the creation and disposal of a product. The second study showcased different scenarios such as ecotoxicity, but both studies leave one major thing out: plastic pollution.
Neither of these two studies, for some reason, mention plastic pollution and microplastics as a factor in determining the eco-friendliness of the alternative. This is strange to me, saying that we are currently living in a plastic crisis. Microplastics are found in fish, even those we buy at the grocery store. Plastic bags have even been found at the bottom of the ocean.
The first study claimed that 40% of consumers reused plastic bags as a trash carrier before tossing them out. But they did not look at paper bags as something that people use as a trash carrier after use. Claiming that “Paper bags were assumed not to be reused as bin liners, as there was no evidence that they could successfully be reused for this purpose.“
While the US and UK might have different ways of going about things, I have seen hundreds of people in my life alone who use paper bags for this purpose. This includes various times in my dumpster diving adventures where I have seen paper bags and even cardboard boxes used as trash recepticles.
The one thing I did not see, however, is recycled paper bags. While Denmark might not have recycled paper bags as commonplace, most locations that I have seen have paper bags made out of at lease some recycled materials. Walmart, Whole Foods, and even Cracker Barrel, Mcdonalds, and more are using paper bags made from post-consumer recycled paper here in the US.
So it would be interesting to know how low the eco footprint of a paper bag goes when accounting for post-consumer recycled materials, especially 100% post-consumer recycled content.
Every single study that I have seen looked only at convential cotton tote bags bought new. They took into account the harvesting of the cotton, the production of cotton into a textile, and the shipping of the cotton tote bag from China to the US. They do not look at factors such as pollution from dying and bleaching the fabrics.
The 2018 Danish Report does look at Organic Cotton vs Conventional Cotton Vs a Jute Composit Bag. It shows that conventional cotton bags would have to be used 7100 times to mitigate the overall harm from the manufacturing of the bag. Neither of these studies take textile recycling or reuse of the cotton fabric into mind.
That study also shows that organic cotton is 3 times worse on all counts than conventional cotton, but only claims that this is because organic cotton has a 30% less yeild and isn’t as bundled together than cotton is. But the fact that organic cotton uses less pesticides and uses better land management processes overall is not factored in. I cannot grasp how this is estimated to be 3 times worse though, as that number seems to come out of nowhere.
(chart showing how many times someone needs to be reused to counteract their eco footprint, but it also ignores many factors, as explained in this post.)
It is almost as if they took the impact of cotton production and times that number by 3 and never bothered to explain why they did that. Especially because in the report itself, it says that:
“ As far as the carrier bag material is concerned, organic cotton provides environmentally pref-erable productionconditions by avoiding the use of fertilizers and pesticides, but with a lower yield. The lower production yield translates in overall higher environmental impacts connected to its production“
But that makes little sense unless you are ignoring vital factors, such as the dying process, which is far more sustainable and often isn’t dumped into rivers in poverty-stricken countries and villages.
What ignoring cotton vs organic cotton, else else can we find?
Alternatives to Conventional Cotton
The second study does look at jute bags made from 80% jute, 10% PP, and 10% cotton. The overall impacts of buying these bags new were only a tenth of conventional cotton production. This makes them a far better alternative, needing to be used only 23 times to begate the greenhouse gas emissions to produce it, and 870 times to eliminate their overall impact. But can we do better?
Go to just about any thrift shop and you can find tons of these reusable tote bags made from all kinds of materials. Pretty much all of them have been used at one time or another, and often as storage or for carrying groceries. As a result, their impact is already far lower.
Despite what these studies say, you do not have to buy a brand new tote bag. We have so many on the market already that buying a new virgin material bag would just be a waste.
Cotton can be recycled. Textile recycling plants are a thing, despite what these studies might have you believe. There are a ton of tote bags on the market right now that are made with 100% recycled cotton. As a result, these bags have a far lower environmental footprint, as factors such as the growing of the cotton, and even the dying process for the most part, is no longer part of the equation.
If you have a cotton t-shirt or button up shirt, etc, that you might have worn a few times and you might have worn once or twice more before donating, you can turn that into a tote bag. DIY tote bags have a far lower impact, and since you have used the clothes in the past and plan on using them for longer, it is a great way to reduce your impact to almost zero.
Upcycled reclaimed Fabric
(This is a tote bag that I sell on my etsy shop, Upcycleability)
This is what I do with my shop. I take clothing that people have thrown in the garbage, and use those textiles to create new projects, such as a tote bag. Since these are post-consumer textiles and salvaged from the landfill, their overall impact is basically zero. With the exception of something like shipping, or the electricity used by a sewing machine or a small iron.
Overall, there is a lot that we can do to lower the impact of the bags we use at grocery stores. Upcycled, recycled, and thrited tote bags are your best option. But whichever you choose, you can be happy with your choice that it will not be tossed out almost immediately and cause massive harm to sea turtles and ocean life.
Just make sure that you USE the bags and do not buy a ton of tote bags and never use them. That helps nobody, and actually harms the environment.
