From soil to seed to pan to freezer to pot to pile to soil.
There’s now a “stock bag” in the freezer as a permanent resident. Carrot tops, onion skins, garlic butts, celery ends: they all go in the bag as they depart from their meatier bits that are bound for the pan.
When the bag is full, it goes in a pan to boil and salt, salt and boil, until there’s the most lovely green broth with which to base a soup.
The simmered remnants go to the compost pile, where they transform into soil to feed the future harvest of carrots and onions…

When is dinner?
6pm most nights. Come on over; it’s a circus these days but always tasty!
And to think all that goes into the trash at my house. I need to repent. Or my Dear does. Neither of us have learned enough about the circle you refer to in the title.
My first compost bin as an adult was a covered plant pot on my balcony. You, too, can use your bits for soup and your soup bits for soil.
