progressive demising of fossil fuel and more energy consumption, which led the
world nations in search of eco-friendly renewable source of energy such as bagasse
(Saxena et al., 2009).
Gasification is a process employed to overcome the disadvantages caused during
combustion of bagasse, such as increased particulate matter in the environment,
which leads to the promotion of health problems and loss of energy and heat during
the process. This has promoted the search for a sustainable technology in the pro-
cessing of bagasse, the production of synthesis gas “syngas” (mainly H 2 and CO),
which gives a value to bagasse, since the contamination caused by syngas is much
less with higher added values (Figueroa et al., 2012). Syngas production from
bagasse by the gasification process is the thermochemical conversion of biomass in
the range of 500 C 1000 C in the presence of a gasification agent (Go ¨ransson

et al., 2011). Apart from above major industrial uses, bagasse is being used in con-
struction due to its high tensile strength and modulus as reinforcement in compo-
sites (Hajiha and Sain, 2015). In the form of geotextile, nonwoven fibers made
from bagasse are used in aquaculture, such as weed control, pile wraps, and filtra-
tion processes (Ajmeri and Ajmeri, 2016). Depithed bagasse is an alternative in the
paper industry (Rainey et al., 2013) and also serves as a raw material for paper-
based coindustries such as packaging, printing, tissues, and newsprint.

12.2.2 Cane tops as biorefinery

Cane trash including tops and green leaves are postharvest residues on the field,
which bring major benefit to the agricultural production. It constitutes about 35%
