Decrease plastic recyclables volume, possibly a shredder? Answered
We recycle everything that our county accepts, and by far, the plastics take up more space than anything else. There is a large amount of air volume inside and between bottles. I've seen the trick where you compress the bottle and then screw on the lid, but this isn't practical for a lot of containers. What I would like to see would be some way to reduce a plastic container to smaller pieces that would take up less space. It needn't be ground into pellets, just cut small enough to reduce the wasted air volume.
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. :-)
