Corn waste

Types of Corn Wastes

Corn is a useful crop that is grown in many parts of the world. It has many uses, and after harvesting it, a lot of materials are still left over. These materials are called corn wastes. They include dried leaves, husks, cob, and stalks of the corn. Corn waste can be gathered each year in large amounts. When it is processed with the right machine, it can be turned into energy, animal feed, or a bioproduct. The table below shows some common types and uses of corn waste.

• Corn leaves: Corn leaves are usually collected together after harvesting the corn. They are sometimes called corn fronds. The leaves are shaped like a fan. While some parts of the corn plants are very fibrous, the leaves themselves are more tender. The corn leaves can be used for two things - to wrap around other foods like meat during cooking or to feed livestock.
• Corn silk: This refers to the many long threads that grow out of the ear of the corn. It used to be seen mostly as a nuisance when people try to eat sweet corn. Research has now shown that corn silk is rich in bioactive compounds. It can be harvested, dried, and extracted to get active compounds that are useful in the healthcare sector. Sometimes, it is also used in traditional healing practices.
• Corn husks: The corn husk is the green covering that grows over the corn cob. After the corn starts to ripen, the green color changes to light brown and becomes papery. Corn husks have three major uses. They can be dried up and used as a raw mat for artisan craft. Hominy is a processed food that uses corn husks. Hominy can be made into a dish called menudo, which is a traditional Hispanic food. When dyed with colors, corn husks can be made into beautiful dolls to represent the Hispanic culture.
• Corn cobs: Corn cobs are the hard inner part where the corn kernels grow. It is left behind after the sweet corn is harvested. Corn cobs are often ground up to make dietary cellulose for livestock. They can also be used as a material for bioplastic production or as biofuel.
• Corn stalks: The corn stalks are the sturdy, long parts of the corn plant that hold the leaves and cobs up. Corn stalks are commonly used as feed for ruminants.
