Well this I hadn't heard of before! I stumbled upon this bin when in Camberwell, Melbourne. It is a solar power, self compacting bin and it is a new intelligent infrastructure that is reducing the collection frequency of rubbish bins in dense urban settings. I don't know about these ones specifically but they look to be very similar to BigBelly Bins from the UK.
- An internal compactor increases the litter capacity by 6 - 8 times that of a normal street bin
It sends an email & text when the bin is 85% full
Management & operatives can view, on desktops and smartphones, the real time fill levels of
all bins, eliminating “milk round” type collection rounds
Eliminates overflowing bins
Eliminates weekend collections
Eliminates birds/vermin scattering rubbish across streets, parks & beaches
Reduces street cleaning & litter picking requirements due to enclosed nature of bin
Comprehensively and successfully tested by Councils for vandalism and for health & safety
regulations since 2005
Each Big Belly can transmit a Wifi Platform providing local Council information and local
retailer offers. This are no costs to the Council associated with this service

It definitely makes sense to try and reduce the frequency of collection, the effects of which can be realised not only in a reduction in carbon emissions (from rubbish trucks etc) but also in the ease of traffic congestion on rubbish days. Being 100% complete solar powered they are self-sufficient and the BigBelly Bins are even boasting Wi-Fi hot-spots and interactive data sharing so councils known exactly when the bin needs to be collected. I think they should replace all bins in the CBD of Melbourne and be paired with 'recycled materials' model as well.
A case study conducted by the City of Philadelphia titled 'Cost Savings from Solar Powered Compactors for Trash and Recycling' [Link] can give you some more info.
