Production and application of activated carbon from sugarcane bagasse

Every year the sugar industry in the United States; emitted 8.6 million tons of bagasse is burned to most steam production; the rest is wasted or used as a low-value products. Granular Activated Carbon (GAC) from bagasse has many advantages compared with bone charcoal or activated carbon from bituminous coal is still used as a kind of color removal for roads; and other production processes.

It is currently conducting research and evaluation of GAC ability bleached bagasse sugar than other types of activated carbon are being sold on the market.

Currently we are working on sugarcane bagasse into ( GAC ) used for many purposes; such as bleach or coarse sugar reducing organic pollutants and metal ions in wastewater.

American sugar refining industry uses large quantities of charcoal and bone GAC from bituminous coal to produce l6.000 tons of refined sugar per day. Both adsorbent bleaching of raw sugar are effective but bone charcoal ( the product from cattle bones) to import; to be affected by the instability of the international market and domestic bituminous coal; but have America but supply is limited.

The cost of coal production from coal GAC bone and approximately $ 1.21 and $ 4.41 / kg . GAC origin bagasse can be used as detergent for colored sugar detergent instead of colors available in the market . Price of coal is also low compared with bone char and activated carbon derived from coal due to lower production costs.

Bagasse – byproduct in sugar mills – in its natural state is weak adsorbent for organic compounds (such as the color of the line) or metal ions.

A method is being applied to dramatically increase the adsorption capacity of bagasse as surface treatment materials . This process is done most effectively by turning bagasse into activated carbon . Carbonization process occurs simultaneously with the chemical bagasse denatured – Management at high temperatures in oxidizing atmosphere not . Granular activated carbon is created by mixing bagasse and various adhesives or high temperature pyrolysis offers. Activated carbon in CO2 or water vapor at high temperature.

Bagasse had to be crushed , mixed with a binder , pressed into cakes or pellets to have a density of 1.2 g/cm3 , and bring pyrolysis , and if necessary, activate the oxidation.

The presence of different binders in the GAC from bagasse has affected the chemical properties – its management. Generally , activated carbon from sugarcane bagasse using molasses binder is not appropriate for bleaching process by:

– Are far
– Also contains high ash content .
– The control will impact the transition cane sugar ( sucrose ) into glucose and fructose.

To overcome this drawback , it from bagasse is mixed with a binder is corn syrup; thereby bleaching the ability to translate, and improved roads . The NAV is being tested to replace the use of activated charcoal is used as detergent for colored raw sugar now.

In addition to making use of activated charcoal colored detergent raw sugar; it also continues to expand the field of application to removal of organic compounds and low molecular weight metal ions in industrial wastewater and urban. To test the study , we used a circular charcoal tablets , not caking coals. The experimental results show that compared with conventional types of activated carbon, from bagasse adsorbed copper ions adsorbed better; but less organic matter. Thus the possibility of using this carbon to produce raw sugar bleaching is very promising. For U.S. domestic consumption potential is very large .

Agricultural wastes such as rice straw, sugar beet, and sugarcane bagasse have become a critical environmental issue due to growing agriculture demand. This study aimed to investigate the valorization possibility of sugarcane bagasse waste for activated carbon preparation. It also aimed to fully characterize the prepared activated carbon (BET surface area) via scanning electron microscope (SEM); and in terms of surface functional groups to give a basic understanding of its structure; and to study the adsorption capacity of the sugarcane bagasse-based activated carbon using aqueous methylene blue (MB).

The second main objective was to evaluate the performance of sugarcane bagasse-based activated carbon for indoor volatile organic compounds removal using the formaldehyde gas (HCHO) as reference model in two potted plants chambers. The first chamber was labeled the polluted chamber (containing formaldehyde gas without activated carbon); and the second was taken as the treated chamber (containing formaldehyde gas with activated carbon).

The results indicated that the sugarcane bagasse-based activated carbon has a moderate BET surface area (557 m2/g) with total mesoporous volume; and microporous volume of 0.310 and 0.273 cm3/g, respectively. The prepared activated carbon had remarkable adsorption capacity for MB. Formaldehyde removal rate was then found to be more than 67% in the treated chamber with the sugarcane bagasse-based activated carbon. The plants’ responses for this application as dry weight, chlorophyll contents; and protein concentration were also investigated.


Preparation of activated carbon from sugarcane bagasse (SCBAC) is a promising approach to produce cheap and efficient adsorbent for gas pollutants removal. It may be also a solution for the agricultural wastes problems in big cities, particularly in Egypt. MB adsorption tests suggest that the SCBAC have high adsorption capacity. Formaldehyde gas removal in the plant chambers indicates that the SCBAC have potential to recover volatile gases.

The results confirmed that the activated carbon produced from sugarcane bagasse waste raw materials can be used as an applicable adsorbent for treating a variety of gas pollutants from the indoor environment.
