Blimey. I'm genuinely shocked by the frequency of some of these collections!
We have a general rubbish collection every two weeks, and I really struggle. I have a disabled 13yr old DS who is still in nappies, and I reckon that around half to two-thirds of my bin is used nappies. (Before anyone asks, absolutely no chance of swapping to re-usable nappies as he has bowel problems and basically poos continuously all day long, bless him).
We have a food caddy that is collected weekly along with our weekly recycling (plastic/card/glass). The recycling van doesn't always turn up - sometimes they appear a couple of days later, sometimes it's not until the following week. That means we have a week of everyone leaving their recycling out on the street because we don't want to miss the collection if they do turn up! Before Christmas there was a big issue with not enough recycling staff so the collections were only once every three weeks or so - hence everyone being concerned about not missing a collection now, just in case that happens again!
Other than the lorry not turning up, no issues with the general recycling.
The food caddy though - we don't use it. We live right next to the river and the area is rife with wildlife. I left a bag of dog food in the boot of my car - the rats/mice smelt it and ate through my fucking car to get to the food!!!! The car was a write-off. Livid doesn't even cover it!! But I learnt my lesson - no food to be left anywhere in the vicinity of my car - or house.
If the vermin can nibble through my car, they can definitely eat through a plastic caddy. I'm not taking the chance of attracting them to my property again. We've only just got rid of a party of squirrels from the bloody loft!
We put our food waste in the general bin but there's very little, to be honest, because we have a dog. And a human dustbin aka DP 😅 It's usually mainly chicken bones from roasting a chicken, and potato peelings etc.
So I don't think food takes up much of the main bin space, but we really do struggle because of the nappies. We regularly run out of room and have even have had to make runs to the local tip to dispose of black bin rubbish - and that's grim having that in the car!
If we went to three week collections, we'd not be able to cope - unless they introduced nappy collections, then we'd be fine! Although I imagine the bin would still be stinky from food sitting inside for three weeks....
