For the past two years I have not put out a trash can at the
curb while my neighbor's trash cans are filled to the brim.

What gives?

Here's what I throw out:
1. Everything that is "food" gets composted, so, there's no actual
food in the trash (and yes, bones and meat and oils are food
just as much as carrots and spoiled ketchup or mustard is food).

2. Every "container" containing food is rinsed out, so, the container
itself is clean (for the most part), and the container goes into
the "blue" recycling bin (which is 60 gallons I believe).

3. Every box or piece of paper or wrapper or envelope or anything
whatsoever with printing on it goes into the recycle bin.

4. I almost never have electronic waste (once or twice a year?) so
let's forget about TVs and refrigerators and batteries and
broken cellphones, etc. since they're so rarely put in trash.

5. About the only place there is anything even remotely resembling
"trash" is the bathroom. But even there, all biologically soiled
tissues go down the toilet, so, the trash contains bits of
cotton balls or q tips or nose-blowing tissue paper, all of which
goes into the blue recycling bucket (it's not pretty, but it's
recyclable).

6. Everything that pays the CRV of five and ten cents goes into
a special bucket for dropping off to get my CRV back, so, there
are very few bottles other than clean food bottles and jars in
the recycling.

7. I almost never have clothing trash, although they're recyclable
anyway, so, the once a year I throw out a pair of jeans would go
into the recycling bins anyway.

8. Of course, all yard waste would go into the green landscaping
bins, so, let's not even discuss leaves and branches here.

9. No babies for quite some time, so, there are no soiled diapers
to worry about (and anyway, we always used the cloth ones
so there's nothing to recycle except the wash water which goes
down the drain).

10. Motor oil is a separate thing, which happens two or three times
a year, as do tires and mechanical parts, all of which are
recycled in their own way already (e.g., tires go to Costco
while motor oil goes in jugs set alongside the trash bins).

So, given that my brown trash bin is never used, what on earth do
people *put* in their trash bin, that can't be recycled otherwise?
