Decrease plastic recyclables volume, possibly a shredder?
I've thought of two possibilities, but I'm open to other suggestions. One is some kind of motorized shredder that would grind/cut the plastic. The other is a large container, similar to the slap-chopper kitchen gadget, that would have blades to slice the plastic.
I have three main requirements. It must be more convenient than taking scissors or a knife and manually cutting up the bottle. It must be able to handle most common plastic bottles up to large laundry detergent size, and reduce their overall volume. The third is it must be fairly safe to use. We will be adopting soon and I don't want to have to worry about small children falling into the bottle grinder. :-)
