What are cottonseed hulls and what are their uses?

People are very familiar with cottonseeds. They know that they are the seeds of the cotton plant and that they can be used to extract oil or be used as medicine. However, people do not know much about cottonseed hulls. Many people do not know what cottonseed hulls are, let alone what uses they have in life. In fact, cottonseed hulls are part of cottonseeds and they are also of particularly high value and are widely used in life.

What are cottonseed hulls?

Cottonseed hulls are actually the outer shells removed when people use cotton seeds to extract oil. They are also called cotton rinds. However, the size, color and length of cotton fluff are not the same. They have a lot to do with the variety and moisture content of cotton, as well as the machinery used to process cotton seeds. However, the obtained cottonseed hulls have the same uses in life. They can be used to cultivate edible fungi and can also be made into beverages or handicrafts.

What are the uses of cottonseed hulls?

1. Made into feed

Cottonseed hulls are also rich in plant protein and a variety of minerals and amino acids. They can be used to make feed for livestock. However, cottonseed hulls contain a certain amount of gossypol. If livestock are directly fed with cottonseed oil, this toxic substance may cause poisoning and is not conducive to their growth and development. Therefore, cottonseed hulls must be fermented after collection before they can be made into feed suitable for animals.

2. Cultivation of edible fungi

Cultivating edible fungi is also an important use of cottonseed hulls. When people use it to cultivate edible fungi, they need to disinfect it, add water to ferment it, and then put it into clean edible fungi bags, then put in the strains, and then put the bags containing cottonseed hulls into a suitable environment, spraying appropriate amount of water every day. As long as the cultivation method is correct, cottonseed hulls can quickly grow edible fungi. A considerable part of the mushrooms sold on the market are cultivated with cottonseed hulls.

3. Produce biogas

Biogas is a combustible gas that can replace liquefied gas, and cottonseed hulls are an important raw material for making biogas. When using cottonseed hulls to make biogas, a built biogas pool must be available. The prepared cottonseed hulls must be placed in the biogas pool for fermentation. Biogas will be produced during the fermentation process. People can collect this biogas and use it instead of liquefied gas, and it can also be used in industrial production.
