Concept:
Agro-based industries are industries that use agricultural products as their raw materials. These industries depend directly on farming and plantation outputs such as crops and plant products.
Step 1: agro-based industries.
Industries such as sugar, rubber, and coffee processing rely on agricultural products like sugarcane, rubber latex, and coffee beans obtained from plantations.
Step 2: the non–agro-based industry.
Cement is produced using raw materials such as limestone, clay, and gypsum which are obtained from minerals and rocks rather than agricultural products.
Step 3: .
Since cement is a mineral-based industry and does not depend on agricultural raw materials, it is not considered an agro-based industry.
