Industries can be classified based on the type of raw materials they use into the following categories
→ Agro-Based Industries These use plant and animal-based products as their raw materials. Their examples include food processing, vegetable oil extraction, cotton textile manufacturing product processing and leather industries
→ Mineral-Based Industries These utilise mineral ores as their primary raw materials. These industries produce materials like iron, steel, cement and chemicals that are used in various sectors. Products from mineral-based industries often serve as inputs for other industries.
→ Marine-Based Industries These use products derived from the sea and oceans as their raw materials. Their examples include seafood processing, fish oil extraction and industries related to marine resources.
→ Forest-Based Industries These utilise forest produce as their raw materials. These industries produce items like pulp and paper, pharmaceuticals, furniture, and building materials, primarily using wood and other forest resources.
