Sometimes I'm asked what I do with all of the plastic I collect. I make a plastic Matryoshka Brick out of it. I'll demonstrate below with the plastic trash from my own home:
(plus one big blue pretzel bag)
One goes into the next, and into the next, and into the next, until everything ends up tightly compacted into one larger bag - It's dense and heavy - My thinking is that it contains all the little landfill-bound non reusable/recyclable pieces, into one secure bundle. The intention is to keep the little pieces, and the lightweight fly-away pieces from falling out of the garbage bin, and onto the ground/into the gutters, as it is tipped into the truck on trash day.
Incidentally, containing all of the plastic like this results in a really small weekly bag of landfill (for this family of four) each week. I should have taken a picture of that as well... but our entire trash takeaway for the week is roughly 1/4 of a small (plastic) kitchen waste bag. The rest is recycled, or composted (we're fortunate to have a stellar municipal composting program that picks up our compost - yard and kitchen - every week - meat, bones, cheese, pizza boxes, paper towels, moldy leftovers, bacon grease, banana peels - it all goes in with the grass & yard clippings).
