Adding to a culture that is already responsible for enormous amounts of waste... and you want to create more?
Its all well and good that you can buy cheap tablets to just throw away, but how many are going to be needed over the lifetime of an event like this? How often do they need to be cycled, and how much will that cost?
How do you properly and responsibly recycle these disposable tablets after theyve been used? You cant burn them, and they are potentially contaminated so you cant ship them elsewhere to be recycled or give them away or allow them to be recovered for fear of spreading ebola again. Batteries need to be recycled properly, and other materials used have a degree of recyclability which should be respected.
And whos going steal something thats been in an ebola treatment centre anyway?
Any sensible person would probably stay the hell away from it for fear of getting infected. Of course I do use the distinction "sensible person" and many crims dont really fit with that, but Im pretty sure they'd even be a little wise to this.
But if you look at pictures of the tablets, and read about them, these things are quite distinctive, not your generic tablet you could flog at the local pawn shop. Theyve been modified, fitted in to a sealed case, fitted for wireless charging since there cant be any open ports where germs could accumulate or the chlorine solution could leak in to the electronics of the device and ruin it, etc.
Im going on the assumption that a lot of these things have been thought about, including solutions that could well have been easier and cheaper to implement, and they didnt just go with the most elaborate solution for the sake of doing so. What theyve come up with is re-useable, so it doesnt need to be disposable.
