SECONDARY SECTOR
This sector generally takes the output of the primary sector and manufactures finished goods.
This sector is often divided into light industry and heavy industry.
Many of these industries consume large amounts of energy and require factories and machinery to convert the raw materials into goods and products. They also produce waste materials and waste heat that may pose environmental problems or cause pollution.
