Coconut husk has high amount of lignin and cellulose, and that is why it has a high calorific value. The chemical composition of coconut husks consists of cellulose, lignin, pyroligneous acid, gas, charcoal, tar, tannin, and potassium. The predominant use of coconut husks is in direct combustion in order to make charcoal and Coir making. Coconut husk can be transformed into a value-added fuel source which can replace wood and other traditional fuel sources.
The husking of coconuts produces multiple byproducts for gardening, including chips, dust and fiber. The fibrous part of the husk, known as coir, lends itself to the creation of a growing medium. Gardeners turn to this alternative medium for its eco-friendly properties, impressive water retention and reusability.
