We have these where I live (UK). We generally have a small kitchen bin, with a degradable liner, that you use to put your scraps in. You then transfer this to the outdoor organic bin.

Honestly it’s way better than having it in your main trash. In the summer you can expect to see flies leaving eggs around the edge of the outdoor bin as they can obviously smell the contents. If you do leave the lid slightly open then yes you’ll get maggots.

When I was younger, everything went in one bin. Collected weekly. Then we got the recycle bin which changed for bi weekly collections for both bins. When I moved we now have a recycle bag, a paper and glass box and the food bin. We obviously also have a regular bin. The recycle stuff is taken weekly. The normal bin is taken once every three weeks. At the time I was like there’s no way we can last three weeks, however if you recycle properly then it’s easily manageable. It’s so much better to send less stuff to landfill.

The organic waste that is collected is sent to be used for more than just compost. You can obviously have a composter at home too though.
