Re: Grapevine canes can be converted into plastic-like material that will decompose

I already use cellulose based bags for my compost waste, and they only stay reliable for about 3 days of usage after something is put in them. This makes them a huge pain to use. I think they also degrade quite a bit (i.e. shorter lifespan in use) after just a few months because each new roll of bags seems better at the beginning.

3 days are more than enough

Isn’t most plastic waste incinerated these days? Is this material much better for that?

I think it highly depends on your city, county, and country. Aren't landfills still super common in the US? The city I live in Germany indeed incinerates most trash including plastic.

The UK banned single use plastic bags at major supermarkets. We all moaned about it for a few minutes, forgot our reusable bags a couple of times and then got on with it. Even the small plastic bags you put fruit or pastries in are now gone in a few super markets - initially, they replaced them with transparent paper-based windowed bags, but then I think people realised you really don't need to see inside the bag, an…

Yeah, I still don't understand why brown paper bags aren't more standard for everything. I do see some manufacturers reducing plastic, fortunately. For example, my box of tea bags used to come wrapped in plastic, and now it suddenly doesn't, and I'm wondering why it ever needed plastic. But there's still so much stuff that comes wrapped in plastic, and often multiple layers of it. Just ban it. There are excellent alt…

I'm old enough to remember when supermarkets only had brown paper bags. They were weak and the handles tear off easily, and anything cold will make the bag wet and it will fall apart usually from the bottom. Supermarkets must have spent a lot of money replacing customer's broken items when bags failed even before leaving the store. So when doing the calculus for brown paper bags don't forget to include the cost goods…

The handles on brown paper bags are noob traps. You're supposed to hold the bag against your body with one arm, your hand on the bottom of the bag. They work fine like this. I've walked home totaling hundreds if not thousands of miles (two or three times a week for many years) with paper grocery bags like this and never had issues.

> (money matters aside - people don't buy because it's more expensive, but despite it), no? I didn't say people buy it because it's more expensive.

Indeed, but removing the money part of your sentence: > They're different types of environmental. One is "I don't like pesticides" and the other is "I don't like eternal plastic waste". Makes its clear that both concerns would come from the same group of people, more or less. Or not? This is my question to you. Just take my previous comment as "What do you mean, different?". You have a point with your money thing. Su…

> I suspect this is how we ended up with this wrapped organic vegetables heresy

It could be that things treated without pesticides might require more protection against things attacking them in transit? Who knows.

Wouldn't the best solution be ensuring they all end up in an appropriate landfill rather than a river? It seems people are so against landfills that they're happy to sort their plastic and sent it on an epic journey of fraud where it ends up in a river in India. Meanwhile it could have been buried with their other trash and appropriately managed.

> happy to sort their plastic and sent it on an epic journey of fraud where it ends up in a river in India It's not like they like this outcome or are even aware of it. We can't blame the individuals who want to do things properly here. The correct solution to "broken recycling chain" is not "let's not recycle", it's "let's fix the recycling chain". The issue with non-reusable / non-recyclable stuff is that we have a…

The issue with recycling, as-practiced, is that there's no lifecycle accounting (in many countries, including most of the US).

If we boosted plastic price at point of sale by a recoverable amount, claimable when returning the container for recycling, we'd get higher participation.

Separately, we should also apply the same to the post-return lifecycle: company pays a premium for the material flow, then it rebated that premium upon proof of recycling.

Brown paper, from recycled fibers are often contaminated with mineral oil residue (e.g. from ink on paper) and other unhealthy chemicals, sadly. There was a report in Germany, years ago, of a range of organic products that failed during testing. They discovered the packaging (recycled paper) was the issue, not the crops and the supply chain before packaging. So, a _really_ biodegradable cellulose bag is desirable. Ev…

Road to hell is paved with good intentions... I wonder how many here even notice the most important comment here from you and just keep repeating how plastic bags are worse. Yes they are terrible, but we shouldn't just blindly replace them with anything and call it a day but do the (continuous) investigation for best solution, poisons are these days everywhere.

>road to hell is paved with good intentions

At some point there are so many bricks in the road, it's direction is so clear, that the intentions are not longer good. At best they are ignorant, but too often they are self serving malice sailing under the flag of ignorance.

I doubt that's made any kind of environmental/ecological impact at all. The cheap, flimsy plastic carrier bags contain orders of magnitude less material than the reusable kind, and had a second life as a bin liner. Now I need to buy bin liners, which are usually made out of sturdier plastic on top of having to get a reusable bag.

Most of the plastic involved in getting food from farm to home isn't the carrier bag or even the food wrappers. It's the massive amount of plastic that pallets of goods are wrapped in for shipping, which happens several times throughout the supply chain.

We should focus on the latter, instead of the former. Pretty much all we're doing is virtue signalling and maybe hoping that it'll make a tiny difference.

Heck, even a marginal improvement in fuel efficiency of trucks delivering to grocery stores would probably do more than these plastic bag shennanigans.

Thankfully we did the full stupid circle quickly enough that the gray hairs in the paper bag industry remembered this and the current generation of bags lacks the handles so people are forced to carry them from the bottom.
