Paper/card is no problem. It can all be laid flat, and often put into a cardboard box they are quite happy to take as well.
However plastic and cans are a different matter. We have a can crusher, which means tins take up minimal room, but ****ing plastic ! It is amazing how much a household of 3 (including one teenager) can go through. And no matter how much we try to crush the plastic bottles (milk, water) and plastic packaging, it still fills about 10 carrier bags.
Ideally, I'd like something like a paper shredder for plastic. Or something which can compact bottles. A quick google for "domestic plastic shredder compactor" suggests I will struggle !
Do any uk diy-ers have solutions for reducing the volume of plastic bottles ?
On a positive note, we used to put 3 or 4 bin bags out a week. Since sorting recycling, we rarely have a full one, which underscores how wasteful we are as a society.
