[LINK] NBN and Batteries

Personally, I think the Greens would do better to tackle battery 
disposal / recycling across-the-board, rather than grabbing  passing 
high-profile issue (the NBN) and tacking "battery disposal" on the end. 
"Pin the tail on the donkey" is a second-rate political strategy; cheap 
opportunism, IMO.

Did some quick Googling on this; a common figure for landfill is 8,000 
*tonnes* of batteries each year - and that datum is 8 years old (from 
the ABS). It's probably more now.

Let's get the calculating envelope:

NBN - (say) 8 million households*
Backup take-up rate - 20% (a guess for the thought experiment)
Battery "failure rate" - 20% annually (ie, five years to turn over all 
Battery weight - 1 Kg (again, a guess for the thought experiment)

*I realise there's an expectation for ultimately 11 million households 
to be covered. That depends on the rate of population growth, so I'm 
thumbnailing this on today's approximate number of households.

That yields 320 tonnes annually - an extra 4% load on battery disposal 
the last time it was measured.

If we regularise *all* battery disposal, the NBN batteries would not 
need some separate special treatment.
