So let me see if I understand what you're doing. You have a simple bin and adding organic household waste to it whenever you have any. Am I right?
My dad has 2 huge bins and constantly stuffing them with everything he has, starting from peelings and weeds, leaves and so on. But those bins are in the garden, on the ground and have no bottom. My heart is aching when I have to throw away good organic waste, but I'm not sure if I can do composting in the balcony.
How big is your bin and do you add soil to it, or just the organic waste?
In fact I put all (or almost all) my organic waste directly into this bin on the windowsill. To be exact, it is 70 centimeters long, 25 wide and about 15 deep. Yes, at the bottom I did put some soil at the base. At first I wanted to use it as a flower box, but when I came back from a summer, everything was burnt and this is how the story started 😉 !
What I find interesting is that no matter how much material I add every day, it all settles and apart from the little bit of compost I take out, I've never emptied it :)
Have a good week ahead !
