It seems like a simple question with a straightforward answer, but when you look at the total environmental impact of each type of bag, things start to get a little complicated.

    A bit of an aside but: please, please please, as someone who works in grocery....wash your reusable bags. You do not want to put your red sticky bloody meats at the bottom of a bag that still has onion peelings, and neither does anyone bagging your groceries... Personally, I prefer cardboard boxes.

    I'm actually a little disappointed that plastic bags are being banned. As others have said, the impact they have is small compared to the shipping of the items, and also, plastic bags are really useful for lining garbage cans. We reuse them a ton at my work (veterinarian) to store belongings that clients bring in for their pets.

    one thing no one seems to pay attention to is that plastic DOES NOT go away. it just wears down into micro plastic particles, filling up marine and small animal guts. phytoplankton is full of microplastics... and its getting worse. every time you launder polyester you wash particles and threads of microplastics down the drain. every lastic item that goes into a landfill is there FOREVER. that cotton bag may look bad, but it wont still be here in a thousand years. anything that is not biodegradable plastic? totally will be in addition, other fibers are far less work to produce, and have lower environmental impact to make

    The issue with plastic is not "it exists," it's that "we don't landfill them efficiently enough." Land-filling plastic is not a problem, so long as it is done efficiently. They need to make sure that it doesn't end up floating away, so people should ball them up and put them inside something else, and/or whoever collects them should do so.

    TLDR: Don't get new bags. Use the ones you have until they die. No mater what they're made of, that is THE most ecologically ethical thing to do. And when your current bags die, replace them with something even sturdier and also compostable - like, hemp or heavy cotton canvas. The whole POINT of reusable bags is that you use the SAME bags until they literally fall apart and cannot be repaired any longer. And then, IF they are cotton, they can be composted - just cut them into little pieces and put them in your home compost. Or, downcycle them into rags for cleaning. The whole point of this movement is to reduce plastic pollution - which is NOT accomplished if you use plastic reusable. They still shed micro-plastics every time they are used, and they contribute to the specifically harmful pollution of plastics manufacture and oil collection that we are eager to put an end to. And, the movement of re-use is also about discouraging further unnecessary manufacturing of unneeded products.

    Fun fact! I take plastic shopping bags and re-use them as yarn! Upcycling allows for that pesky plastic bag to be used for a long time to come. I tend to weave placemats and (ironically) shopping/tote bags using plastic bag yarn, easy to clean, durable to use, and will be used over and over and over again!

    Question: why are you bagging? If I'm on my bike or my scooter, I use a reusable plastic bag. If I'm in my csuv, I take the cart to my car without bagging, use 3 oversized milk crates and 1 reusable for little things, and carry the crates in the house. The crates use d a lot of plastic, but they were bought to store stuff in the basement, and they'll be useable for groceries beyond my lifetime.

    I have a lot of reusable bags> I like CHICO bags alot.. cause they are small when in their little sack. However, during the pandemic we got over to Paper again... but have in the past used them to dispose of cat litter. Honestly, I don't know why folks over complicate this stuff. These report about how using Canvas bags or other bags is not environmentally friendly or that they are dirtier etc.. was a known Propaganda campaign by the plastics industry to counter this. I hate those ugly reusable bags with handles. THOSE I can see being more problematic. Again.. this doesn't have to ba complicated. I also like cooler bags as I have to drive 20 minutes from grocery to home so ...

    For paper bags, how do wood pulp paper bags measure up against something like hemp paper bags? Or bamboo fibre bags? I am told that hemp grows a lot faster than trees, thereby taking less water and fertiliser overall to provide the same yield in pulp. I have been unable to verify this info independently though. Could you do an article comparing hemp fabric and hemp paper to our traditional forms and seeing which is better from an environmental perspective? Then with cotton bags, would up-cycled ones be better than purpose made ones from fresh cotton? I'm inclined to say yes simply because it is re-purposing that worn out pair of pants destined for the land fill into something you can use for groceries thereby saving on land fill usage, and not using fresh virgin fabric for bags, making less of an overall environmental impact. What are your thoughts?

    I'm wary of water use data. There are too many disparate water management systems. Water left to drain into the ocean is more wasted than water recaptured in a treatment facility, but water is so unregulated that it's hard to actually say where the water is going. If we can't track litter (something we can actually see!) how can we say we're tracking water use?

    I just gotta take massive exception with the phrasing used. Total Environmental Impact cannot possibly leave out the disposal cost. I'd be wary of any studies that willingly frame things in such a way, as that reeks heavily of something that would come out of an industry-funded thinktank. Like, the double-think involved in saying that plastic has the lowest total environmental cost but also produces the worst trash problem is baffling.

    You know what the study didn't factor in? Double bagging. Many grocers will automatically double (plastic) bag certain items for you like milk and meat. And they tend to underfill plastic bags. On the flip side, grocers tend to over stuff cotton canvas bags because they are more sturdy and people usually do not bring a million of them to the grocery store.

    I feel one factor left out is quantity. I have three reusable plastic bags and a cotton bag I use for groceries on occasion (not its intended purpose). Two of my plastic ones are large, one is small. The small fits 2-3 plastic bags worth of food in it. The large ones can fit 6 or 7. And I don't need to double bag anything at any point. So if I were to do only a haul of canned goods, totaling 6 bags, each double-bagged cause of weight, I'm using 12 plastic bags. But I used one of my large reusable ones and, well, that's 1. Therefore I feel like the numbers and math are, while accurate, incorrect. It's not a 1 to 1 ratio of use between a single-use plastic bag and a reusable tote (especially if you get a Sainsbury's one in the UK and bring it back home, that fits like 10 regular in it [if packed properly]) With these numbers, a small reusable plastic bag would need to be used 3-6 times according to Denmark and UK, but a large one would offset within 1 or 2 trips. However, I do also recognize that we're unaware of what the volume of the reusable bags they studied was. My smaller one is about the same footprint as single-use plastic. ...Overall, I don't know. It is complicated, fo sho. But we also don't know all the minutia of what's being studied versus commonality. The average size of reusable plastic in the UK is much different than here, as well as different types. They have reusable plastic that feels similar to a single-use. They have thicker ones more akin to what we here in the USA are used to. So uh, yeah. I think I lost my point in there. Back to watching you on Tik Tok!

    This might sound silly, but I've always wondered what the effect will be on poor people when single use plastic bags are phased out. I don't mean to say this as a reason to keep them around -- but if you've never been poor, you might be surprised by how many uses there are for those things. They make great trash bags, lunch bags, diaper/dog poop/cat litter bags -- anything you can imagine, we probably used a plastic bag for it growing up. When you're poor, being able to access those for free as a regular part of shopping legit does make a difference.

    When you say the potato starch bags are worse because of the cost of growing the potato's, but aren't those being grown ANYWAY and used for other products or are they literally using the entire crop just to make bags? Because if they are using by-products then you need to off-set some of that cost for a truely representative value.

What if we ban plastic bags for the benefit of the environment, and for the animals? Would solve the death by plastic problem? What if we sell the bio degradable bags at $3.00 per bag to encourage people to reuse them more? Would that solve the reuse problem? Then would we solve the bag problem after figuring this out, or make it worse?

    The video does a good job in comparing bag for bag, but then it makes a point at the end about reducing the number of bags you use. This is where it misses what I think is a major point. The resuable thick plastic bags you get for a buck at the local store holds the equivalent of 4 or 5 single-use bags. A decent sized cotton bag can hold as much as 6 or 7 single use plastic bags. So rather than compare single bag to single bag, you should consider relative capacity. One reusable thick plastic bag, used 50 times over the course of it's lifetime replaces 200 to 250 single use plastic bags, making its environmental impact significantly less. Similarly, with cotton bags, using it 100 times over its lifespan would replace 600 to 700 single use bags again, significantly reducing its environmental impact overall.

    This is a flawed comparison. Canvas bags hold more. Often three times as much. You can't one to one compare a canvas bag to a single use plastic bag due to capacity. I primarily use an insulated shopping bag which is plastic and canvas. For one it's more durable than a cotton bag. Two, it keeps the frozen food cold on a hot day or not frozen on a cold one. Three, I can use it as cooler for bringing food hot or cold to a gathering. I also use my satchel that I use for my phone, books, ipad, etc. It has enough room to carry nearly a single use plastic bags worth in a pinch. Yet, another bag I keep in my car but rarely use is a light cotton bag that I found on the ground of a shopping center. I upcycled it. (It has some logo I think I save 200 single use plastic bags per year and over the lifetime of the bags above I will save 1500 single use plastic bags or more.

    A thing that's super important in LCA is your unit of analysis. Here, these are all comparing bag=bag. But a thing that is true is that the disposable bags hold a lot less than the reusable ones. If you redid this on the basis of moving "10kg of groceries" you'd get the heavier plastic bags coming out on top after 1 or two reuses because they carry groceries 3:1.

    From a quick scan, they assume that single-use plastic bags will be re-used as waste bin bags *and* then incinerated to produce electricity and heat. They also seem to assume that you need to use 2 organic cotton bags where 1 conventional cotton bag would do (table 8). Very odd.

      Very hard to see how organic cotton, even with their assumed 30% lower yield than conventional, can have 275% greater climate change impact (figure 17).

    If single-use bags are heat-pressed or melted into blocks, can they then be accepted by recyclers?

    On top of that EVERYONE uses single use bags 2+ times. To pick up pet poop, or used in the small garbage cans, or even to hold supplies when going places. So you would have to multiply the findings by at least 2 for the real world use case to get the equivalent value.

    One point that was not mentioned is the impact that harvesting the oil for plastic bags and the timber for paper bags has. Gathering oil is highly intensive and emissions from chainsaws and heavy duty equipment in the timber industry should also be accounted for. Harvesting and manufacturing was taken into account, but not the harvesting methods for the other types of bags.
