But usually paper and cardboard that has been in contact with food is not recyclable because it contaminates the batch. That's why pizza boxes also cannot go into the cardboard/paper fraction.
No, that's because pizza boxes are contaminated with fat. That messes up the paper recycling process. Water is fine.
Many countries have deposits for single use bottles/cans but an electronic device with a lipo battery is seen as perfectly fine to throw away. These things should have 100 times the deposit amount of a can of soda with mandatory requirements for retailers to take the 'empties' back.
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 e…

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.
you can choose to either vape a flavour version only, or one containing a certain amount of nicotine

Which is why when folks nowadays say "you cannot use XYZ for embedded", given what most embedded systems look like, and what many of us used to code on 8 and 16 bit home computers, I can only assert they have no idea how powerful modern embedded systems have become. Now that it is a pity that when people talk about saving the planet everyone keeps rushing to dispoable electronics, what serves me to go by bycicle to w…

Maybe that ticket machine was coded in MicroPython. /s

Go on, give us some numbers. Because 7Bn people multiplied by a few kg/year doesn't seem trivial to me, but sounds like you can prove it.
The main thing about plastic is that it’s made from oil, and oil already exists in the ground. Putting it back into the ground is basically neutral minus the pollution involved in manufacturing.
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…
How close are we to smart dust I wonder? How small can we make wireless communications?
There's two limiting factors for 'smart dust': power (batteries are the majority weight and volume of this vape), and antennae (minimum size determined by wavelength of carrier wave).
I believe you can fit an NFC module in a 5x5mm package, but that does externalize the power supply.

Go further. Every product must be returned to manufacturer at end of life. 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.
You're thinking disposable vapes, but this will apply to quality of life appliances like washing machines as well, right? Do you want to live in a world where only the rich can afford washing machines? Incidentally, I don't know what you do, but once in a while I throw (carefully, li-ion batteries) my broken electronics in the trunk and bring them to the local collection center.

Is that inflation adjusted? If not, the real cost difference is even starker.
