bagasse

What is bagasse?

Bagasse is a byproduct of the sugar production process from sugarcane. When the sugarcane stalks are crushed, a dry, papery material remains, which is called bagasse. Of course, there is a similar substance called agave bagasse, which is obtained from the agave plant. Bagasse obtained from sugarcane is used in the production process of paper and paper pulp, construction materials and various fuels. A fuel that is suitable for the environment and can be used in the production of energy, heat and electricity.

History of bagasse

The word bagasse is derived from the French word bagage, which means waste or residue. For the first time, what remained from the processes of processing plants, such as pressing olives, date kernels and grapes, was called bagasse. But today only sugarcane residue is called bagasse. The main use of bagasse is in the paper industry. The method of using bagasse in paper production was first invented in a small laboratory named Clarence Birdsong in a sugar factory called Paramonga in Peru. With this promising discovery, the company purchased an old paper mill in New Jersey.
He sent bagasse from Peru to test the reliability of this project on an industrial scale. This method was developed in 1937 and the first paper production machines were designed in Germany in 1938. However, bagasse paper was first commercially produced in 1950 in the form of newsprint by Noble & Company Machine Wood. This product was successfully displayed in front of 100 industrial representatives and 15 national officials. The economic importance of this discovery was more than that, especially in countries that did not have easy access to wood fibers for paper production due to their climate. In 2015, the Paramonga sugar factory, which first invented this method, produced about 90,000 tons of paper from bagasse.

Production, storage and properties of bagasse

Considering that bagasse is a byproduct of sugarcane, the amount of bagasse produced in each country corresponds to the amount of sugarcane produced in it. Usually, three tons of wet bagasse are produced from every 10 tons of crushed sugarcane. Brazil and India are the largest producers of bagasse because sugarcane is grown in many areas of these countries. Bagasse is collected through an extraction process from the residue of sugarcane and stored wet to remove any sugars that may interfere with the process. To produce products, to be collected. Then, bagasse is mixed with water, until the resulting mixture becomes a paste and is ready for subsequent processes. Bagasse is stored in different forms and methods depending on its final use.Normally, bagasse is stored at the beginning of the process. For example, in the production of electricity, bagasse should be kept in a humid environment with gentle heating, so that its fibers dry gradually, but on the other hand, in the production of paper and paper pulp, bagasse should be kept moist in order to remove the pulp fibers. be helped Pith fibers make up 30 to 40% of bagasse and their properties prevent paper production.

In general, dry bagasse is chemically composed of the following materials:
  • 45 to 55% cellulose
  • 20 to 25% hemicellulose
  • 24 to 28% lignin
  • 1 to 4% ash and 1% wax
