The City of Guelph, Ontario has a two-stream system. You can reach them at
(519) 767-0598.
Guelph piloted both a 2-stream system and a 3-stream system. They picked
the 2-stream system for citywide implementation because it diverted more
material: residents didn't have the option of throwing recyclables or
compostables in the garbage. In the 3-stream pilot, some recoverable items
were lost in the garbage. Guelph's compost meets Canada's strict
requirements for use in agriculture.
There are lots of "dirty" composting operations around. If you contact
Biocycle magazine they could probably give you a list of facilities that
compost raw garbage (MSW). However, I don't think that MSW composting has
been very viable.
In our food waste pilot, BFI is going to compost mixed grocery store waste.
They aren't going to ask the grocery stores to source separate. They will
remove non-compostable contaminants by hand (prior to composting) and
through screening (after composting). They are only doing a "rough grind"
on the incoming material so that they don't grind up plastic contaminants
too fine. Plastic contaminants greater that 1/2 inch can be easily screen
out. Glass is a much bigger issue. BFI is going for mixed grocery store
waste because their studies of such loads have found that it they are 80-90%
compostable. Our other pilot composter, Z-Best, is asking customers to
source separate their organics, but expects a fair amount of contamination
when they start collecting organics from restaurants. They also plan to use
a "rough grind" and screens to remove the contaminants. They are also going
to offer source separated glass collection to all of the restaurants that
they collect organics from, in order to keep glass from contaminating the
compost. I'll let you know how it turns out.
San Francisco's "Fantastic Three" pilot is three stream: garbage, organics,
recyclables. The organics category includes foodwaste (even meat),
non-recyclable paper, and yard trimmings. This pilot is for both the
residential and commercial sectors. Contact Robert Haley at (415) 554-3439
for more info.

Hi Stephen,
I've been thinking that the solution to this "third
stream" was to just develop a wet side process that
could handle and remove the stuff that needs to be
landfilled. Thus, the collection system is two-steam,
but out of the processing comes three streams ...
recycle, compost and landfill. Of course, there are
also non-recyclable items sorted out of the dry side
too.
Does anyone know anyone working on creating a
compost system which can tolerate a "dirty" stream of
material, which in this case means a lot of non-compostable
material that needs to screened, or whatever, out?
Also, did you ever write up your research? I'd love to
see it!

Removing the trash option means you are either downgrading your compost or
your recyclables (with all the negative market implications that we don't
need) and you also lose the option of placing a heavier financial
disincnetive on buying commodites that aren't recyclable or compostable.
