Re: [carfree_cities] Problem with Waste Removal
- View SourceI've never heard of this Nabble before. It seems strange that they
reproduce the Yahoo! group forums on their page; I wonder how this
happens? In any case, I see from the Nabble page that this is an old
thread from back in May this year. As for your comments:

Certainly pneumatic tube systems would help eliminate trucks,
allowing a carfree city to keep its character. BUT, as far as
sustainability per se is concerned, I'm inclined to think that
pneumatic tubes (similar to the garbage chutes to be found in many
apartment buildings) encourage an "out of sight, out of mind"
mindset. They could very well just encourage people to just toss
everything together into the pneumo-system, rather than taking the
(albeit negligible) time and effort to sort different kinds of throw-
offs, e.g. compostables, plastics, paper, glass, toxic materials
etc., for different purposes. If you want to make pneumatic disposal
systems part of a sustainable solution, you would have to put in
place a whole parallel system for each type of disposable, from the
starting point where a user disposes of their waste (one disposal
door for each type), through parallel systems of tubes, to the end
points of each system where the disposables are processed for reuse.
Of course, this would be far more expensive than an single system
that handles everything, but I can't see how pneumatic tube disposal
would be really sustainable in any real sense of the word otherwise.
I think a truly sustainable overall solution would demand various
different kinds of distinct disposal systems: some of them, for
example compostables, would best operate at a city block level
(unless some kind of special compostables collection service operates
at the city level); others, such as collection of recyclable or toxic
materials (fluids, chemicals, batteries) could operate via regular
collection services using fleets of smaller vans. In fact, some kinds
of recycling cold be undertaken by at-store return programs. Mountain
Equipment Co-op stores have a take-back program for used batteries;
this kind of thing could be encouraged by a combination of retailer-
and user-targeted surcharges, coupled with return reimbursements, for
a whole range of toxic materials. There are all kinds of alternatives
I can imagine that seem to me to contribute way more to
sustainability than a "toss 'em all down the chute" approach.

to facilitate recycling/reuse?

Actually, it is exactly what you mentioned. Let me explain.
The tenant would separate their waste into each different fraction that is deemed by the municipality. Then they would proceed to the Waste Collection unit, press the colour coded button to identify the waste that they are disposing of. The system would then send the fraction to the appropriate compaction container. Our system is a single pipeline that all waste is transported however it is separated via PLC programming and a butterfly valve type of system to redirection the waste accordingly. Our system has software that allows for an excellent tracking device to continually audit the different waste being transported. I could send you pictures if you would like to see how our system works.
