Peanuts are no stranger to everyone, it is a delicious food, however, the leftover peanut shells are often treated as garbage. But did you know that peanut shells are also a biological resource that has many uses. First, peanut shells contain a large amount of crude fiber, high nutritional value, can be made into animal feed. Secondly, peanut shells can also be used as fertilizer after fermentation to provide nutrients for the land. Finally, because peanut shells are rich in wood fiber, they can be made into charcoal and activated carbon after crushing and carbonization.
Making animal food
A large number of peanut shells will be produced after peanuts are processed by oil extraction plants and food processing plants. In the areas where peanuts are grown, there will also be a lot of peanut shells. It would be a pity to throw away these peanut shells as garbage. But if we make them into animals food to feed cattle, sheep, chickens, ducks and other animals, they not only grow faster, but also can replace part of the concentrated feed to reduce the cost of breeding.
Peanut shells can be used to make biomass briquette. The peanut shells are crushed with a wood shredder and then crushed into rods by a professional machine under high temperature and high pressure. These biomass briquettes are often used as fuel. For example, it is used for winter heating and industrial boiler fuel, so the recycled peanut shells become the most environmentally friendly and economical new energy fuel to replace coal. These sticks can be further carbonized to make charcoal, and they are also used as fuel.
Making activated carbon
Waste peanut shells can also be used to make activated carbon. Making activated carbon is further produced and processed by chemical activation method or gas activation method after the peanut shells are carbonized. Due to the characteristics of activated carbon, its pore structure is very well developed, adsorbing metal materials in water or a small amount of harmful substances in the air with very good results. Usually we use activated carbon at home to adsorb odors from refrigerators and bathrooms. In addition, the new house is more formaldehyde, many people will be placed in the house a little activated carbon to absorb indoor formaldehyde.
