Our bins were emptied on Tuesday morning and so far I have one caddy’s worth in my silver bin, a third-full recycling bin and nothing yet in my grey bin.
My kitchen bin that now takes non-food waste only is only half full. It’s noticeable how much food packaging is not recyclable. We don’t eat ready meals, but all the black trays from fresh produce are in that bin, plus plastic wrap from pasta, inner liners from biscuits and cereal etc, coffee bean and cat food pouches. I now have a separate recycling bag for any plastic that says it can be recycled with plastic bags (the shrink wrap on a multipack of tins, for example). That I will take to the supermarket and put in their bag recycling bin.
It seems like the food waste compacts itself down more when kept by itself, but that might be my imagination.
On the basis of this fairly normal week, I don’t think I’ll have any problem with the grey bin being emptied twice a week. For reference - we are three adults and one teenager. Oh, and cat and a dog (hello poop bags). The dog has been very accommodating and not pooped at home this week.
