Final answer:
Inedible by-products that can be created from hides include hair, excess flesh, and wastewater from the tanning process.
Step-by-step explanation:
When hides are processed, there are some inedible by-products that can be created. One common by-product is the hair that is removed from the hide during the tanning process. This hair can be used for various purposes, such as making brushes or stuffing for pillows. Another by-product is the excess flesh that is scraped off the hide, which can be used as fertilizer or compost. Additionally, the salts and chemicals used in the tanning process can result in wastewater that needs to be treated before being released.
