Discussing ways to reduce waste and build community!

Celebrate thrift as a virtue, talk about creative ways to make do, or show off how you reused something!

This may be a stupid idea, but to my knowledge metals is are some of the best materials when it comes to being easily recyclable.

Ignoring the cost and reusability, wouldn't recyclable disposable cups made of metal be a better deal than the largely incinerated plastic cups?

IMO, we don't need disposable cups of any kind at all. They could as well serve a can or bottle in drive-thrus.

[–] Boomkop3@reddthat.com 1 points 2 weeks ago (2 children)

Ye, but that would defeat the point of it being super convenient

[–] bstix@feddit.dk 2 points 2 weeks ago (1 children)

Maybe its me, but I don't find disposable cups convenient at all.

I already have bottles to refund, so the idea of getting drinks served in a piece of garbage for me to dispose of is just a nuisance. Also if I'm ordering for the whole family, I either need to have 4 vacant cup holders in my car or get another piece of disposable garbage to hold the disposable cups. I'd much rather have a standard PET bottle.

I'm with you on that one! Unfortunately that's just not most people. The best thing would be is if they'd just give up options. Sell the cup as an optional thing or something.

[–] gazter@aussie.zone 2 points 2 weeks ago (1 children)

I'm not sure I understand. Are you saying cups are more convenient than cans or bottles?

[–] Boomkop3@reddthat.com 1 points 2 weeks ago (1 children)

No, the convenience (for most people) I think is in that they are able to get a drink regardless of planning. As long as they're in a car, they can get drive trough drinks. No need to have cups ready in the car.

[–] gazter@aussie.zone 1 points 2 weeks ago

Ah, I see. I think the original comment was saying that there's no need for a cup- A can is much more convenient, and you don't need to be carrying a cup already.

Looks like this company is doing just that: https://www.zhongruicup.com/

Not sure how the economics work out, I assume they are much more expensive.

This could be environmentally feasible if the factory ran exclusively on renewable energy, but if not, it would likely produce significantly more carbon emissions than paper cups.

A standard soda can wall is approximately 0.097 mm thick.

These cups are 0.16mm that's a big difference. They also don't have pricing and the site says how to clean and care for your cup.. it is not disposable.

[–] ProdigalFrog@slrpnk.net 1 points 2 weeks ago (1 children)

They seem to be explicitly marketing them as disposable cups for 'eco conscience' events. So, likely for rich corporate conferences or something.

They definitely seem reusable, but probably not durable.

[–] tehWrapper@lemmy.world 2 points 2 weeks ago (1 children)

That's not the aluminum ones they make.

It says biodegradable cups.. aluminum is not that.

Also how to care for the aluminum ones https://www.zhongruicup.com/tips-for-cleaning-and-maintaining-aluminum-cups-extending-service-life

[–] ProdigalFrog@slrpnk.net 1 points 2 weeks ago

ah! my bad, they looked like aluminum so I assumed it was the same product. And you're right, the aluminum ones don't seem to be designed to be disposable either.

[–] tehWrapper@lemmy.world 3 points 2 weeks ago (2 children)

A can holds it shape cause it has the top and bottom. To make an aluminum cup would take a fair amount more aluminum and cost a fair bit more. It would prob be better, but no one is going to pay that much and toss them.

[–] MrMakabar@slrpnk.net 2 points 2 weeks ago (1 children)

Aluminium cans work pretty well. The only thing needed would be to have a bigger hole at the top..

[–] tehWrapper@lemmy.world 1 points 2 weeks ago (1 children)

Aluminum cans are so thin to cut cost that they are like an egg. Open the end more and it will have no support to it.

They would need to be thicker and that would make it much more expensive.

[–] Aussiemandeus@aussie.zone 3 points 2 weeks ago

You absolutely can open the top of one more.

I can use my tooth and take the top right off and make cups out of cans. Do it all the time camping.

They work fine except for the sharp edge because it's just like being opened with a can opener.

You can crush a disposable paper cup easier then a soda can with the top taken off

[–] Boomkop3@reddthat.com 1 points 2 weeks ago (1 children)

If they'd be getting recycled and/or reused, the price shouldn't be as high as new production cups

[–] tehWrapper@lemmy.world 1 points 2 weeks ago (1 children)

I think they would need a deposit system if your expect to get anything back on them?

[–] Aussiemandeus@aussie.zone 1 points 2 weeks ago (1 children)

Where i live we have 10 cent deposits for retuning all recycled bottles and cans

[–] Boomkop3@reddthat.com 1 points 2 weeks ago

It's 15 cents for cans, 60 cents for bottles here

[–] first_must_burn@lemmy.world 3 points 2 weeks ago (2 children)

Ball (canning jar company) makes them, they are semi-disposable and recyclable.

[–] reddig33@lemmy.world 1 points 2 weeks ago

I wonder what the price difference is between the ball aluminum and the red solo plastic?

[–] Boomkop3@reddthat.com 1 points 2 weeks ago

Those look cool! Thank you!

[–] TonyTonyChopper@mander.xyz 2 points 2 weeks ago (1 children)

A few years ago there was this effort to abandon disposable containers entirely, so you were encouraged to carry a durable reusable container instead. Whatever happened to that?

[–] Boomkop3@reddthat.com 1 points 2 weeks ago

I don't think anyone who likes fast food liked reusable containers. Although my girlfriend always carries her water bottle everywhere.

[–] reddig33@lemmy.world 2 points 2 weeks ago (1 children)

Plastic cups currently have an advantage in that it’s fast and easy to pump out on a mass scale on the cheap.

Waxed paper is probably the next best thing for disposable cups. This is what McDonalds and other fast food places use and it’s renewable and biodegradable. The cost is probably pretty close to petro-plastic.

If we ever get a single use plastics tax, or the public starts freaking out more about microplastics, you will probably see restaurants return to paper cups.

[–] Boomkop3@reddthat.com 2 points 2 weeks ago

The mcDonalds here gives us sturdy plastic cups that that'll buy back from you. (or you can leave them after dinner).

I'm going to have a look at this wax paper solution, that's an interesting option! Thank you!

[–] I_am_10_squirrels@beehaw.org 2 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

There is some municipality that is taking this approach. All the restaurants use the same metal cups, and there are return bins around the area. Customers get a drink to go, and return the cup when they're done. It's washed and returned to the restaurant.

I'll have to find a source for this when I'm on my PC, currently on mobile.

ETA: It's Petaluma, CA. https://www.goodnewsnetwork.org/city-experiments-with-reusable-cups-at-starbucks-taco-bell-and-30-other-restaurants-with-return-bins-all-over-town/ and https://returnmycup.com/

[–] Boomkop3@reddthat.com 2 points 2 weeks ago

Yoo, cool! I'll have a look, thank you!
