When plants and animal based products are used as raw materials, it is called agro-based industry, e.g. cotton textiles, leather, edible oil, etc.
When minerals are the raw materials, it is called mineral-based industry, e.g. iron and steel, petrochemical, etc. The products of mineral-based industry feed other industries.
When products from seas and oceans are used as raw materials, it is called marine-based industry, e.g. sea food industry.
When forest produce are the raw materials, it is called forest-based industry, e.g. paper, furniture, pharmaceutical, safety matches, etc.
On the basis of size
When products are manufactured by hand and by artisans, it is called cottage industry. Basket weaving, pottery, etc. are examples of cottage industry. A small amount of capital is invested in small scale industries.
Large Scale Industry
When a high amount of capital is invested, it is called large scale industry. Large scale industry also produces in large volumes, e.g. automobile industry.

When workers or producers join together to form a company in which profit and workload are equally shared, it is called a cooperative, e.g. Amul, Lijjat, Mother Dairy, etc.
Factors Affecting Location of Industries
Availability of raw materials, land, water, labour, power, capital, transport and market are the main factors which affect the location of an industry. A place where some or all of these factors are available is an ideal place for the growth of industries. Sometimes, the government provides incentives; in the form of subsidized power and tax holidays; to develop industries in a particular location. Industrialization usually leads to development and growth of towns and cities.
- Input: Raw materials, labour, land, transport, power and other infrastructure are the inputs of industry.
- Processes: A variety of activities which lead to transformation of raw materials into finished products.
- Output: Products or services are the outputs of industry.
