We put veg cuttings in the garden bin (onion skin, end of lettuce, any manky bits), any bits of bread or leftover cooked veg out for the birds. A few grains of rice or whatever left on the plate would just stick inside the food bin. We serve almost everything at the table rather than dishing out in advance so we take what we need and can store leftovers in the fridge or freezer and are good at using them all up eventually (slow cooker meat might end up in a wrap with salad, leftover omelette or pancake slices defrosted for DS snacks while out etc). We get chicken breast and sometimes steak so there's a tiny amount of fat, which most weeks would be the only thing I could think to put in the food bin and I'm not entertaining the foxes for the sake of ~10g of chicken fat that would probably be stuck to the bin or left behind as the binmen assume it's "empty".
I've seen various recycling messages making a big deal out of food waste and I just don't get it because I can't think of what could go in the food bin. It can't be about food at the dump because the smell of food on non-recyclable bits of packaging would still attract rats and whatever. All I can think is that some people have lots of excess food wastage, but then shouldn't they just be more careful about the food dates and how much they cook / how they serve?
Obviously IABU to judge, so enlighten me please, what do you put in your food waste bin? Why are we unreasonable (if we are) by not using ours for those bits of chicken fat?
