London's Dow Jones Architects have proposed "a radical series of waste-crunching towers across London to help meet recycling targets and generate low-cost energy for local communities," Building Design reports.

In order for the city to reach its goal of becoming "85% self-sufficient in terms of waste by 2020," a new waste-management infrastructure is required – thus the need for "new buildings in Greater London to house advanced waste technologies."
These would offer an alternative to the greenhouse gas-producing incineration method used by most waste service providers contracted by councils. Dow Jones and Arup assessed the scale of buildings that would be needed to deal with certain amounts of waste using specific technologies, then scattered them on four hypothetical urban sites, proposing them as “parts of the city and building types that would form an appropriate match.”
While this further convinces me that today's most interesting architectural projects are the ones that thoroughly rethink civic infrastructure – waste-treatment plants, algae farms, solar towers, tide-power generators, high-speed rail lines, space elevators – it also makes me wonder what an even more distributed form of sustainable waste-management might look like.
Why not ten sites, for instance, scattered throughout the city, instead of four – or twenty-five, or a hundred?
By decentralizing waste infrastructure as much as possible, you could much more thoroughly integrate quote-unquote sustainable behavior into the spatial fabric of everyday life.
I'm reminded of the differences in public recycling infrastructures between a city like Berlin and a city like Los Angeles. In L.A., for instance, you actually have to drive – often quite far out of the way – to a neighborhood recycling drop-off point simply to get rid of things like wine bottles and old magazines, whereas in Berlin you're almost constantly walking past what could be called recycling micro-stations: color-coded clusters of separate waste receptacles organized by type (glass, paper, aluminum, etc.).
My point is simply that recycling becomes what you do there – like breathing, it's the autonomic nervous system of the city – in much the same way that throwing things away is simply what you do in the United States. After all, as has been widely remarked elsewhere, urban infrastructure in the U.S. seems to be built to encourage the thoughtless and efficient throwing away of more things.
So it's a change in lifestyle that would come about through the ubiquitous, lace-like distribution of micro-infrastructure across the urban landscape.
On the other hand, I don't mean to imply that Dow Jones's waste towers are just recycling stations. From Building Design:
Waste that can’t be recycled or composted would be turned into energy or useful materials using techniques such as anaerobic digestion – which produces the low-cost fuel biogas plus compost – and advanced thermal treatments, which produce syngas for industrial processes plus a vitreous slag that can be used as a construction material. The gases produced can be routed in closed loops to produce power for local electricity and heating networks serving nearby homes and workplaces.
Nonetheless, eliminating large travel distances between key pieces of "green" infrastructure and its users – i.e. the residents of the city – can be one of the most important steps in ensuring that this infrastructure will be used at all.
Knowing that a power-generating, construction waste-processing, compost-accumulating bio-tower exists somewhere in the northern suburbs of the city is certainly inspiring as a first and early step toward the design of a 21st-century city – but these sorts of things should, wherever possible, be more thoroughly integrated into the everyday streetscape.
Instead of superblock, think filigree.
Sustainable waste management will become simply what a city does.

I think you're spot-on about weaving recycling and sustainable behaviours into the fabric of urban life. Here in Toronto we have those Berlin-style recycling clusters, and even the vending machines in Tokyo that dispense PET bottles have multiple slots where one can deposit used bottles and cans. I was utterly delighted when I first laid eyes on both.
