Nearly every food crop has some parts that are too fibrous for people to eat. These are referred to as crop residues or biomass waste.
Examples:
- banana leaves
- peanut shells
- coconut shells
- empty corn cobs with no kernels
- rice husks
- sunflower seed husks
- straw
Uses:
- All biomass waste can be burned for energy.
- Some kinds of biomass waste can be converted into packaging.
- Some kinds of biomass waste can be fed to ruminants (cows).
- Some kinds of biomass waste can be used for cultivating mushrooms.
- If there's no other use, biomass waste can be composted back into the soil.
3 and 4 are both ways to convert fiber into human-edible protein & calories. Help figure out which of these processes is more efficient overall. This page doesn't have enough information yet - join the discussion discussion.

Soybean meal is not counted here, because it can be turned into human food (soy flour).

If this could be converted into packaging, it would probably be more than enough to replace all disposable plastic.
Energy
If all of it was burned for energy, it would be equivalent to burning: (calculation loading)
If it was burned in a power plant, the electricity generated would be:

Biomass energy is nowhere near enough to power the world.
