[elearning] Re: [Yr7-10it] E-waste and Computer Bank

[Meadows, Roslyn M]

Interesting...one thing that annoys me is if I use a recycled print
cartridge in my colour laser at home (a samsung) it comes up with a
message "Invalid Toner Cartridge" and insists I replace it with a
"genuine Samsung cartridge" My HP inkjet did the same thing but I
somehow managed to fool it and get it working. The Samsung will only
work when all 4 cartridges have ink in them also, so you can't keep
printing black copies if one colour is empty...grrrr

I feel like making a complaint to Samsung, but it would just be lost in
somebody's inbox...

Cheers

Thanks Tony, responses below.  :-)

Nobody wanted old CRT monitors. As most of the old CRT monitors we gave 
ComputerBank were still working, it was indicated that they were going 
to use them for the computers that they were building or reconditioning 
for resale. I think I read somewhere that there have been some trials to

use the lead glass as an aggregate mix with concrete.  This may be a 
better outcome for broken monitors than  burying the issue. As a rule, 
we should not make more stuff that we cannot later safely trash.

True, except I imagine that transporting them for landfill is going to 
present the same problem. The cheapest way would then be for each of us 
bury it in our backyards or cheaper still, hide it behind the shed. :-)

 From the tour that I had of the setup at ComputerBank in North 
Melbourne, the disassembly is done locally and into different recycling 
streams for local processing in Victoria. It is a difficult balance, 
either you spend energy to recycle to remove a problem or save energy to

create a problem.  I have read of some horror stories about eWaste that 
has ended up in China. Not good.

Good question, staff keep chucking polystyrene into the dump master. I 
like it better when IT stuff ships with special airbags that can be 
quickly popped with a pen or sharp object. I wonder what is the best 
option for packing or even for recycling polystyrene?

Good point. A company that claimed to save schools money by recycling 
toner cartridges was just dumping the washout into the local creek. We 
now participate in a scheme where these cartridges are shipped back to 
source and a PlanetEarth box for stuff that cannot be returned to
source.

Peter Singer raised some interesting environmental ethical issues that 
are worth exploring such as "What environmental obligations do we need 
to keep for future generations?"

Without leading students down a particular path, this good stuff to 
engage them in the bigger issues outside the IT classroom.

Thanks for the feedback. :-)
