Question

Name some by-products of sugarcane and their uses.

Name the byproducts of sugarcane and give two uses for each.

Answer 1

1. Molasses: It is used to produce industrial alcohol, fertilizers, rum, treacle and yeast.
2. Bagasse: It is used as fuel for mills and mainly used for paper, fibre board and synthetic fibres.
3. Press mud: It is used to make wax, shoe polish and carbon paper.

Answer 2

The three main industrial byproducts of sugarcane are bagasse, molasses, and pressmud.

The uses for each are:

1. Bagasse
   • Biofuel for Energy: It is burnt in sugar mill boilers to produce high-pressure steam and environmentally friendly energy that powers the processing facility.
   • Paper and Packaging: It is a sustainable, tree-free raw material used to make paper, cardboard, and biodegradable food packaging.
2. Molasses
   • Alcohol and Ethanol Production: It is the primary raw material for fermented and distilling industrial alcohol, alcoholic spirits (such as rum), and environmentally friendly ethanol fuel blends.
   • Livestock Feed Additive: It is mixed into cattle and poultry feed with high-energy, nutrient-dense ingredients that improve animal health and palatability.
3. Pressmud
   • Organic Fertiliser: It is mixed with organic matter to create a rich compost that replenishes nitrogen, phosphorus, and organic carbon in agricultural fields.
   • Wax Extraction: Sugarcane wax is processed industrially and used in the manufacture of shoe polish, protective fruit coatings, and cosmetics.
