It is the dry stalks of wheat plants remaining after the grain has been harvested. Composed primarily of cellulose, hemicellulose, and lignin, this agricultural byproduct represents a significant portion of the overall plant biomass. Consider a vast field of golden wheat swaying in the breeze; once the grain is collected, what remains are these stalks, ready for various applications.
Its importance stems from its versatility and abundance. Historically, it has been employed as animal bedding and feed. More recently, it is being recognized for its potential in sustainable construction materials, biofuel production, and as a component in packaging. Its readily available nature makes it a viable alternative to less sustainable resources.
