I would actually say that nappies make up less than 1/4 of our none recyclable/compostable waste to be honest. A very large proportion of our waste is stupid bloody none recyclable packaging! I mean ffs, there ARE alternatives to polystyrene available these days (expanded maize for one). It helped a bit when tetrapaks became recyclable, but then that was just one more thing filling our blue bins....
The thing is as well HC, I dunno if you are a similar age to me or not, but when I was a kid you did NOT waste food etc. These days try the same methods our parents used raising us and you have a social work ringing your doorbell... Tell a kid that they eat the meal in front of them or go hungry and you are neglecting the child. Modern parenting has changed a lot, thanks mainly to bleeding heart liberals and people who genuinely abused the more relaxed nature of laws etc back then. But then, when I was a kid we had a lidded black bin and a weekly collection, and the 'bin men' as they were back then WOULD take bags put by the bin as well.
I still fondly remember the argument I had once with somebody over cloth nappies, not least as they took their kids to and from school, every day they were in school, in a big fuel guzzling 4x4 (this is a woman, not a man, in my experience many 4x4 drivers are actually women. lol), who had the affrontary to rant at me that we should be using cloth nappies immediately... Then they got started on moon cups, and I exhited the thread promptly when she started on about plant food....
Oh and as said, we tried to deal with the waste food problem by using Bokashi bins. We ended up with 8 of them, as to be blunt they DON'T work! All you get is partically fermented food, and this is after over a year of been sealed up.
Thank heavens for our compost bins though, as without them we would be producing even more waste! The fact is though, our kids generate 80% of our waste, both recyclable and none recyclable, and getting rid of the kids isn't an option, really it isn't. lol
Oh and don't even get me started on how badly the bin collections failed last winter! The annoying thing was, the bin truck drove past our street, which was CLEAR of ice and snow, for about 2 months in a row. We had to get family and friends in the end to take RUBBISH to the local recycling centre. Our back yard was piled high with black bags! Only for the council to refuse to allow them to be collected alongside the normal green bin. Now THAT was a good one for blaming an increase of vermin on for sure!
