For these devices the microcontroller needs to be super cheap. Microcontrollers like the Puya PY32 Series (e.g., PY32C642, PY32F002/F030) can cost in the $0.02 - $0.05 range for the kind of many-million volumes applicable for disposable vapes. These are 32-bit ARM Cortex M0 MCUs, running at a 24 MHz clock or similar, some with 24 KB of ROM and maybe 3 KB of RAM!
To put into context: this is 3x the ROM/RAM of the ZX81 home computer of the early 1980s. The ARM M0 processor does full 32-bit multiplication in hardware, versus the Z80 that doesn't even offer an 8-bit multiply instruction. If we look at some BASIC code doing soft-float computation, as was most common at the time, the execution speed is about 3 orders of magnitude faster, while the cost of the processor is 2 - 3 orders of magnitudes less. What an amazing time we live in!
Why stop there? I think more or less every non-durable product manufacturer (say, lifespan less than 5 years) should be required to take the product back at end of life and dispose of it properly. Trash is an enormous externality. I'm talking about plastic clamshells, container lids, "disposable" storage containers, the lot.
> more or less every non-durable product manufacturer (say, lifespan less than 5 years) should be required to take the product back at end of life and dispose of it properly
Yeah, we had that. Glass milk bottles and coke bottles and bulk goods sold out of barrels by the lb rather than in plastic bags.
But then plastic took off and soon after Big Sugar paid a PR/lobbying firm to run a campaign with a fake Indian crying a single tear and calling every Tom Dick and Harry a “litterbug” and now the pile of garbage is our fault, not the manufacturers.
Switzerland has something like this for "eWaste", it's called the ARC [1] (Advance Recycling Contribution). For any electronic device you purchase a small tax is collected and used for the recycling and collection of the future waste it will generate.
The collection mandatorily happens in the shops that sell electronic devices, you don't have to return them to the exact store where it was purchased, as long as they sell similar devices they cannot refuse to take it back (without paying anything more). It works pretty well, even if shop owners/workers aren't always pleasant when you return something.
We have it in California, just for monitors for some reason, but on Jan 1 a new law covering battery-embedded devices took effect. That new one specifically doesn't tax vapes (???)
But if you think it through, it's intractable. You need to 2x+ the transportation cost of all products (it will cost more to get them back for multiple reasons, including products not being as neatly packaged and often going from many-to-one transportation to many-to-many). Companies also need to double their specializations and adopt recycling processes that will largely be redundant with other companies; you basically make it impossible for small companies to make complicated products. And are we including food products, the majority of trash? It makes a lot more sense to centralize waste repurposing and benefit from economies of scale.
Waste management is already a very profitable industry. Of course, it's wasteful, just burying stuff, and environmentally harmful. But I'm of the opinion that it will soon be economically viable to start mining landfills for different types of enriched materials, and government subsidies could bridge the gap for things that are of greater public interest to recycle.
I've been working on the software side of the technology needed to do this in my spare time for a couple years, waiting for some hardware advancements.
> You need to 2x+ the transportation cost of all products... Companies also need to double their specializations and adopt recycling processes that will largely be redundant with other companies
I think 3rd parties would spring up to deal with that stuff
The amount of completely useless plastic garbage that we would be sending back east would be mind-numbing. They don’t have anywhere to put that trash either.
It's an externality because the entity that sold it to you doesn't have to pay the consequences of dealing with the trash. OP said "dispose of it properly," which could mean a lot of things, all of which are better than leaving it on a beach.
Trash disposal (to regulated landfills, not beaches) is enormously inexpensive and increasing the cost of every item through a laborious return program doesn't improve anything.
> Nearly all the plastic humans have made still exists.
And it just doesn't matter. It's a tiny amount of mass / volume.
> The great garbage patch in the Pacific is growing fast.
Ocean plastics are almost entirely a consequence of (particularly Indonesian) fishing net waste, not Western consumer products disposed of in managed landfills. The "great garbage patch" is also very much overstating the scale of the problem; it's a slightly higher plastic density region of ocean.
> Even if the retailer took it back it would still be... trash.
Yes, but making them deal with it would create a massive incentive to either reduce the amount of rubbish they make, or to make it recyclable/processable.
Why though? Bottles/cans are easily recycled and I believe the small reimbursement is easily recovered during the recycling costs.
It's not profitable to recycle small electronic devices otherwise you'd see heaps of shops doing it. It's toxic, hazardous and labour intensive.
100 times the deposit amount would be like $5-10 USD per-device which is insane. I do agree that any retailers should be required to take back empties and dispose of them responsibly.
> It's not profitable to recycle small electronic devices otherwise you'd see heaps of shops doing it. It's toxic, hazardous and labour intensive.
Sounds like they should be banning their sale and/or production then, just like many jurisdictions have been with plastics and other non-recyclable items. These devices are not an essential-to-life item where the waste produced is justifiable, especially when you consider the LiPo batteries, which are a borderline-environmental disaster from the moment the lithium is mined to the day that battery finds its way to a landfill. Why single-use disposable vaping devices exist in the first place is somewhat perplexing given permanent/re-fillable ones are also available, often right beside the disposable ones, and generally offer a significantly lower cost of ownership.
That's a good point. In America we call this type of deposit a "core charge." The "core" is the component you return to the store to get your deposit back.
This is done for components like starter motors, alternators, power steering pumps, batteries, and a variety of other components. The complex components are re-manufactured to like-new specifications and the less complex components are recycled to recover materials. The battery is a probably the only component where the potential ecological impact drives the cost of the deposit.
You paying a nonzero cost for creating a negative externality is an improvement compared to the status quo, in the context of this economic philosophy of discouraging production of negative externalities by aligning economic incentives.
The problem is you can’t find any company willing to recycle them. Because of the nicotine content, I’ve heard e-waste recyclers consider them hazardous waste and refuse to touch them.
yeah, e-waste recyclers suck, they love to ship it all to the 3rd world where piles of circuit boards get tossed in an open fire and stirred by kids to reclaim the metals.
I still think the next evolution of these vapes is for a Tamagotchi-esque device to get built into them and to have the pet grow when you inhale through it. You're already walking around with enough tech - why not gamify it more?
Currently working on a method to recycle / repurpose the li-ion cells obtained from the disposable vapes, trying to scale up the recycling effort by releasing products to fund the manpower required to breakdown and sort the vape components . Getting close to releasing the first 100 demo models of the product for stress testing in the wild. Currently based in the greater Seattle area and here is a link to my site if anyone wanted to know more:

I've just started a Salvage Pile in my workshop. Laser printer with fax modem was the first for excision and harvest. I could feel the addiction take hold before the last of the plastic shell was tossed into the refuse bin. The stepper motors alone!
I have a huge old microwave on the blocks next. After that a series of small odd ball electronic toys and a few early LED bulbs. If I ever come across a vape, I'm sure it'll make its way on to the shelf.
With regards to the microwave, here’s a token “please safely discharge and double check the cap” comment!
With regards to vapes, just look on the ground near a sidewalk. I find like 3 or 4 big depleted vapes a day in a US urban area. Closer to 15 or 20 in greater London in the UK.
As a second regards the microwave, depending on the age, please be extremely careful about the magnetron the insulators on which could contain beryllium oxide, which can kill you.
There are a lot of fun parts inside microwaves (a personal favorite is the high-torque-low-speed-line-voltage motor, which I use to make creepy Halloween decorations) but the caps, transformer, and magnetron are all useful for somewhat... more dangerous... pursuits.
the insulators on which could contain beryllium oxide
As far as I can tell, this is an urban legend. No consumer microwave oven has ever used beryllium in its magnetron insulators. Military radar ones, yes (and likely where the legend started.) Some specialist test equipment and RF transmitters too, and they all contain prominent warnings of it. Besides its toxicity, it's far more expensive than regular alumina.
That's my understanding as well, but I still wouldn't disassemble a 1960s microwave without protection (I have assisted in the dismantling of a couple microwave communications devices which did contain BeO and were also very well-labeled as such). Anything from the 80s on at least is almost certainly aluminum.
The reason disposables are so popular in the US is the FDA banned any flavored cartridges, which doesn't include disposables. The immense battery waste is a direct result of a relatively new law.
Yeah, in my state, with disposable I can get any flavor. But if I want juice or pods, I can only get nasty tobacco flavor. It's an easy choice.
Also, when you do get juice online or from other states, it doesn't hit as hard / the same as whatever they put in the disposables. Someone told me it's because the disposables have vitamin E acetate in them that makes the nicotine get absorbed into your blood quicker.
I think the disposables go around more regulations, which mean the chinese manufacturers can put more addictive stuff in the pods / disposables.
The FDA just hates flavored nicotine products because they're appealing (to both adults and children), and the FDA doesn't want nicotine products to be appealing (because nicotine is perceived to be a public health problem on the scale of tobacco).
Did that in Australia - the problem is even worse now. Disposable vapes were a market response to banning and restricting pod vapes (where you can keep the base and just swap out the pod).
Nicotine policy and policing has been a clusterf - not only are there wasteful disposable vapes everywhere, but a thriving black market that has lead to firebombings and murders.
Sounds like they didnt ban it properly. There aren't really nicotine junkies like heroin. So I suspect ban nicotine and slowly everyone stops using nicotine sources.
Everyone I know who vapes nicotine is a junkie about it.
In fact, nicotine habits can be harder to kick than heroin. I know plenty of people who have tried to kick nicotine many times and cannot stay off of it.
Anyway, it's moot, because outright banning tobacco is insane.
New Zealand was making really good progress on getting down the smoking rate with a variety of measures (primarily ramping the tax).
The current government has started rolling back decades of progress, and SURPRISE, they have close ties to the tobacco industry including MPs who worked for tobacco companies.
Why do we need to ban these? I'm not trying to be contrarian, but why do some people appear to be for banning tobacco but not alcohol? I don't claim to have all the answers or even strong opinions, but if your going to ban one recreational drug with negative externalities you should ban them all. I'd much rather hear people's opinions then ask AI.
> If alcohol came inside of little battery powered computers, we should ban those too.
I too am agnostic but do not understand this reasoning. BTW let me get severely downvoted by saying that if alcohol prohibition came up for a vote I'd vote yes in a heartbeat.
It doesn't stop addicts from craving and it doesn't curb the appeal of the product. People who think tobacco/nicotine bans would work are people who think they don't have any positive effect associated with them.
People don't smoke because the evil cigarette companies tricked them and now they are addicted. It's a drug, it feels good to do it.
A tobacco/nicotine ban will end up exactly like aby other recreational drug prohibition.
They are straight up banned in Australia but you often see them chucked in the gutters and rivers. Only seems like they started raiding the stores in the last few months.
The vape ban in Australia is utterly stupid though. All vapes are banned, not just disposables, and guess what's easier to discretely sell to kids from a newsagency.
Doesn't seem to have stopped kids getting their vapes yet I need to import my cannabis vape via the black market.
They're not all banned, you just need a prescription to get one which realistically should've been implemented day 0.
Eventually it'll prove very impactful with the youth, it'll reduce the number of users and make it more cost prohibitive to be so prolific as it is right now.
They do seem to be banned in an around 10 states at this point though there is some sort of existing stock law or something so if you ask them you still seem to be able to buy them. They don’t seem to be on display anymore though.
Doesn't look like SMD was great. This looks like lowest cost has gone back to .. rows of people with a soldering iron patching the cheapest possible flow process.
These products are targeted towards high school teens and middle schoolers, carry a number of serious health risks, and anyone involved in making them can rot in hell.
It's not rediculous if you look at this through a modern lens. In reality this tech is cheap. Trying to keep it around is hoarder mentality. You are stockpiling garbage which can be cheaply replaced.
And this, kids, this is how an adult sucks when he tries to adulting.
And if you want for people to reconsider something they are doing you reaaaally shouldn't insult them in the first place. Even if you are grown-ass adult who can't stand that something.
The ESP32 (with Bluetooth and WiFi) is like $5 on AMZN. Which is probably sub-$2 in any meaningful quantity in Shenzhen. We've been living, at least until the tariffs, in a StarTrek like world where whatever we want is available from Shenzhen for a ridiculously low price (which in many respects is better than "free" because "free" brings with it its own humongous problems).
I'm amazed there isn't more of an outcry against these things. I'm not an environmental activist, but even I'd feel wrong just throwing something like that away.
To put into context: this is 3x the ROM/RAM of the ZX81 home computer of the early 1980s. The ARM M0 processor does full 32-bit multiplication in hardware, versus the Z80 that doesn't even offer an 8-bit multiply instruction.

What an amazing time we live in!
These things should have 100 times the deposit amount of a can of soda with mandatory requirements for retailers to take the 'empties' back.
I'm not kidding :)
Yeah, we had that. Glass milk bottles and coke bottles and bulk goods sold out of barrels by the lb rather than in plastic bags.
But then plastic took off and soon after Big Sugar paid a PR/lobbying firm to run a campaign with a fake Indian crying a single tear and calling every Tom Dick and Harry a “litterbug” and now the pile of garbage is our fault, not the manufacturers.
Maybe the process could be emulated.
Every bit of plastic humans have made still exits, bar a small amount we have burnt.
That’s concerning.
A lot of people wouldn’t want this because it’s asking for stuff to become more expensive for them.

Any items found by garbage program will be collected and returned to manufacturer at cost.
All items sold in country must be identifiable for this purpose. Importers are considered the manufacturers and must retrofit products.
Then we would be getting closer to capturing the total burden to society.
But if you think it through, it's intractable. You need to 2x+ the transportation cost of all products (it will cost more to get them back for multiple reasons, including products not being as neatly packaged and often going from many-to-one transportation to many-to-many).

Make less waste. Use less plastic.

I suspect you could make the same argument for manufactured cigarettes vs pipe tobacco. It seems people will pay for convenience.

You can't "just ban" it or "ban it properly". You would get a very nasty black market and things with such ban.
