If you are a mother who periodically finds half a peanut butter sandwich, the bottom of a cupcake or a partially eaten cookie left by a child whose eyes were bigger than their stomach, there is a solution other than the "momism" about starving children in Africa (China, Bangladesh, Uganda ...). In a friend's house, the scraps are deposited in a large, covered, plastic container labeled, "good-will can".
This page contains the following solutions.
If you know anyone that has chickens, save ALL your scraps, peelings, and fruit skins and give them to the chicken's owner. This keeps my garbage disposal and septic clean and the chickens have fruits and vegetables year round.
I have regrown green onions and celery roots in my kitchen to provide extra seasonings. Simply put the cut off root in a shallow bowl of water (enough water to submerge the root area, but the top should be left out in the air) and set on the windowsill.
I do not like throwing away vegetables or fruit that is going to go bad before it gets eaten. Now I put it all into a container before it goes bad.
Making soup from leftover scraps can be surprisingly good. Use up your leftovers, and freeze your vegetable scraps to make a low cost nutritious soup.
