Genuine question Custardo: what does your waste consist of that so much is generated?
Between my neigbours and ourselves (ie 4 adults, 3 children in total so I'm not talking about a hypethetical "elderly couple"), me working from home, neigbours at home 2 out of 5 days, we still struggle to fill one wheely bin in a fortnight. I make a packed lunch every day for ds and dh - but they bring home the "rubbish".
All that goes in my family's "general" waste bin is margarine tubs (at most, one a week), yoghurt posts (c.10 a week), empty takeaway curry container (2 a fortnight), a few empty plastic wrappers (eg from the bag of apples or the spaghetti/pasta), foil butter wrappers, crisp bags (c.5 a week), fruit juice cartons (c.10 a week - but only small ones), chicken carcass once a month, lamb bone once a month, maybe 2 or 3 plastic meat "containers" per week ..... and now I'm struggling to think what else there might be. I empty the (small) pedal bin in the kitchen about twice a week. The waste paper bins in the other rooms add up to about another small (re-used) supermarket bag's worth. That's about all the goes in the general waste wheely bin.
I suppose if you use a lot of tetrapaks, the volume could mount up.
Tissues go in composting. Cardboard goes into recycling - except egg boxes and loo rolls which go onto the compost heap. Sugar and flour wrappers goes in compost.
If we are having a big clear out, then we might go onto the 2nd wheely bin - to take the broken (plastic) toys or frost damaged planters.
Even when ds was in (disposable) nappies (a long time ago now) we still generated far less waste than our old neigbours - less than half a bin a week (and back then, we couldn't put cardboard in our recycling bin). New neighbours generate a similar amount to us.
