bagase

Bagasse is a fibrous material obtained from crushed sugarcane stalks after the juice has been extracted for sugar production. It is a by-product of sugarcane processing and contains roughly 50% moisture. Sugarcane (Saccharum officinarum) is widely cultivated in tropical regions, and global production reached approximately 1.84 billion tonnes in 2017. It is processed in sugar mills and distilleries; however, these facilities cannot fully utilise the fibrous residue left behind, which amounts to about 30% of the plant’s biomass. This residue is known as bagasse. It was traditionally burned as waste. Today, bagasse is mechanically shredded, cleaned with water, and pressed into sheets in a process similar to handmade paper production. These sheets are used in a wide range of applications, including the paper industry and as a raw material for moulded products such as food packaging and disposable tableware, as well as a source of biofuel. Sugarcane bagasse is a lignocellulosic material, meaning it is composed mainly of cellulose, hemicellulose, and lignin. Because it contains a relatively high amount of cellulose, bagasse can be further processed to extract cellulose for various applications. Its fibrous structure makes it suitable for use in textiles and construction materials after appropriate treatment. It can also be used as reinforcement in composite materials, contributing to the development of more sustainable and partially bio-based alternatives to conventional synthetic composites.
