Sugarcane refers to a number of species and hybrids of tall perennial grass in the genus Saccharum and tribe Andropogoneae. They are used for the production of sugar.
Complete step by step solution:
The plants are two to six metres or we can say six to twenty feet tall with stout, jointed, fibrous stalks that are rich in sucrose, which accumulates in the stalk internodes.
Bagasse, molasses and press mud are sugarcane residues.
Bagasse: It is the dry pulpy fibrous excess that remains, after sorghum stalks are smashed and the juice is extracted. It is beneficial as a biofuel for the production of heat energy and electricity and in the manufacture of pulp and building materials. Many research efforts have explored using bagasse as biofuel. This bio fuel is used as a renewable power generation source. Bagasse is also used in the production of bio-based material. It is frequently used as a primary fuel source for sugar mills. Bagasse, also called megass, is additionally used as a source of cellulose for manufacturing animal feeds. It is considered an essential ingredient for the production of pressed building board, acoustical tile and other construction materials. Bagasse is readily available as a waste product with high sugar content and has the potential as an environment friendly alternative to corn, as a source of biofuel ethanol.
Molasses: Molasses or black treacle is a juice extracted from crushing or smashing sugarcane and it is boiled in order to concentrate it. Molasses differ based on the amount of sugar, method of extraction, and age of the plant. Molasses are used as the principal ingredient in the distillation of rum. They were also used in some cookies and pies. Also, they are used as a source for yeast production. Molasses are soil additives that promote microbial activity. Molasses is composed of 22 percent water, 75 percent carbohydrate, no protein and very small amount of fat.
Pressmud: The utilization of press mud is for fertilizers in both unprocessed and processed form. Press mud is also a residue or left over from sugarcane after extraction of juice. Press mud is also called filter cake or press cake. It is used to produce top quality bio manure.
Hence bagasse, molasses and press mud are some of the types of by-products of sugar.
Therefore, the correct option is B.
Growing sugarcane is very profitable as even waste of sugarcane can be used to produce different by-products.
From harvesting to final processing, there are four main sugarcane waste by-products produced which are sugarcane bagasse, sugarcane tops, sugarcane press mud and sugarcane molasses.
