Sugarcane is mainly grown in Sindh and Punjab provinces of Pakistan. Sugar mills must be located near sugarcane fields because sugarcane starts losing sugar content after harvesting and must be crushed immediately. It is also bulky and heavy to transport far. Byproducts of sugarcane processing include bagasse, which is used as fuel and to make paper, and molasses, which is used to make various chemicals.
3. Raw Materials
Sugar is mainly made from sugar cane.
The main areas of sugar-cane
production from Sindh to Punjab are
widely spread. As sugar cane is a
tropical crop, it can’t tolerate frost.
General output
of sugar cane
is 37.5 tonnes
per hectare.

5. Sugar mills have to be located near the
sugarcane fields because:
•sugarcane starts losing its sugar
content as soon as it is harvested. It
needs to be crushed immediately.
•sugarcane is bulky and heavy.
Therefore, its transportation cost is
high.

8. Products and By-products
• Sugarcane is used primarily in the making of
sugar, ghur and other sweet products.
• By-products are:
1. Bagasses: Used to make paper, chipboard,
animal feed and also used as a fuel to produce
electricity to run machinery in sugar mills.
1. Molasses: Are used to produce various types
of acid and ethylene, which can be turned to
packaging plastics.
14. Uses of processed sugar
Sugar has many uses:
•As a sweetener: Sugar is added to foods or drinks to
make them taste more pleasant. For example, it
balances the bitterness of coffee and reduces the
tartness of sour fruit.
•As a preservative: Sugar is a natural preservative
that binds water to prevent the growth of micro-
organisms, thereby reducing food spoilage, as in jams
and preservatives.
•As a bulking agent: Sugars gives texture to a variety
of foods, from jams to frozen products.
