Crop residues
Nearly every food crop has some parts that are too fibrous for people to eat. These are called crop residues.
Examples
- banana leaves & peels
- peanut shells
- coconut shells
- empty corn cobs with no kernels
- rice husks
- sunflower seed husks
- straw
Uses
- All crop residues can be burned as fuel.
- Some kinds of crop residue can be converted into packaging.
- Some kinds of crop residue can be converted into protein.
- Most commonly: By feeding ruminants (cows, sheep, goats).
- More efficiently: By cultivating mushrooms (the kind you can eat).
- If there's no other use, crop residues can be composted back into the soil.
