Corn cob
Overview
Corn cob granules, processed from the woody core of maize cobs, serve as a multi-purpose industrial material. They are available in various grades to meet specific needs in filtration, surface treatment, and absorption tasks. As a renewable byproduct of agriculture, they provide a sustainable option for B2B buyers seeking efficient, natural alternatives.
Features
These granules exhibit consistent physical properties, including low moisture for stability and varied particle sizes for customized use. Key features include high absorbency for liquids and a mild abrasive quality that protects delicate surfaces.
Applications
Common uses span water filtration, gentle blasting for metals and wood, oil spill cleanup, pesticide carriers, and animal bedding, with regional preferences like blasting in the U.S. and bedding in Europe.
Advantages
Evidence leans toward cost savings through reusability and lightweight design, reducing shipping expenses. Their organic composition supports biodegradability and non-toxicity, potentially aligning with green procurement policies, though certification is recommended for verification.
