Ethanol From Cassava

Updated: Feb 22, 2023

The global demand for ethanol has been increasing in recent years, driven by several factors such as the need for cleaner-burning fuels, the desire to reduce dependence on fossil fuels, and government policies to promote the use of biofuels.


One of the main drivers of the global demand for ethanol is its use as a fuel. Ethanol is often blended with gasoline to create a cleaner-burning fuel, known as E10 (10% ethanol and 90% gasoline) or E85 (85% ethanol and 15% gasoline). This blend reduces emissions and can help countries to meet their environmental and energy security goals.


Another driver of the global demand for ethanol is the need to reduce dependence on fossil fuels. Ethanol is a renewable fuel that can be produced from a variety of crops such as corn, sugarcane, and cassava. This makes it an attractive option for countries that want to reduce their dependence on imported fossil fuels.


Government policies also play a significant role in the global demand for ethanol. Many countries have implemented policies and targets to promote the use of biofuels as a way to reduce greenhouse gas emissions and improve energy security.


The global demand for ethanol is expected to continue to grow in the coming years, driven by increasing demand for biofuels and the need to reduce dependence on fossil fuels.


Ethanol production in Africa is a relatively new industry, but it has the potential to provide a significant boost to the continent's economy. The use of ethanol as a fuel can help reduce dependence on imported fossil fuels, create jobs, and improve food security by using crops such as cassava.

In Africa, Ethanol production from sugarcane is most common especially in South Africa, Mauritius, and Malawi. The process involves converting the sucrose in the sugarcane into glucose and fructose by hydrolysis, which is then fermented and distilled to produce ethanol. This ethanol can be blended with gasoline to create a cleaner-burning fuel.


Ethanol production from cassava is also growing in some countries in Africa. Nigeria, for example, has a large cassava farming sector and has been investing in the development of the ethanol industry as a way to improve food security and reduce dependence on imported fossil fuels.


However, the ethanol production in Africa is still limited due to various factors such as lack of infrastructure, limited access to technology and capital, lack of awareness of the benefits of ethanol, and lack of regulations to support the industry.


Despite the challenges, there is potential for the ethanol industry to grow in Africa, especially as the demand for biofuels increases globally. With the right policies and investments, the ethanol industry in Africa could help to improve the continent's energy security, create jobs, and boost economic development.


Usefulness of Ethanol.


Fuel: Ethanol is often blended with gasoline to create a fuel that is cleaner burning and reduces emissions. This blend is known as E10, which is 10% ethanol and 90% gasoline.

Solvent: Ethanol is a common solvent for many industrial and laboratory processes. It is used to extract essential oils from plants, dissolve certain types of gums, and as a carrier for perfumes and flavors.


Alcoholic Beverages: Ethanol is the main ingredient in alcoholic beverages such as beer, wine, and spirits.


Pharmaceuticals: Ethanol is used as a solvent and antiseptic in the manufacturing of many medications and personal care products.


Cleaning products: Ethanol is used as a component in cleaning products as it is a good solvent and has a low toxicity.


Alternative fuel: Ethanol can be used as an alternative fuel in vehicles designed to run on flex fuel.

Industrial uses: Ethanol is used in the production of many industrial chemicals such as acetaldehyde, acetic acid, and ethylene glycol.


Cassava as a feedstock for Ethanol production.


Cassava is a root crop that can be used as a feedstock for ethanol production. The process involves converting the carbohydrates in the cassava into sugar, which is then fermented and distilled to produce ethanol. The starch in cassava is broken down into sugar by enzymes or acids before fermentation, which can be done using yeast or bacteria. After fermentation, the ethanol is separated from the liquid by distillation, producing a high-purity ethanol product.

Cassava is a good feedstock for ethanol production because it is a hardy crop that can grow in poor soil conditions and with low water inputs, making it well suited for cultivation in developing countries.


Setting up a small-scale ethanol factory from cassava involves several steps:


Obtaining cassava: The first step is to secure a steady supply of cassava. This can be grown on your own farm or sourced from local farmers.


Processing the cassava: The cassava root is then washed, peeled, and grated to extract the starch. The starch is then fermented to convert it into glucose.


Fermentation: The glucose is then fermented using yeast or bacteria, which converts it into ethanol. The fermentation process takes several days to complete, and the ethanol content of the liquid can be measured to determine when it is ready for distillation.


Distillation: The fermented liquid is then distilled to separate the ethanol from the water and other impurities. This produces a high-purity ethanol product that can be used for various applications.


Equipment: To set up the factory, you will need equipment such as a grater, fermentation tanks, a distillation column and condenser, storage tanks, and a bottling or packaging line.


Permits and regulations: It is important to check and comply with the local regulations and obtain the necessary permits for setting up and operating an ethanol factory.


Marketing: Once the ethanol is produced, it is important to identify the target market and create a strategy for sales and distribution.


The main processes involved in ethanol production from cassava are:


Cassava preparation: The first step is to prepare the cassava by washing, peeling, and grating the root to extract the starch.


Starch hydrolysis: The starch extracted from the cassava root is then broken down into glucose by enzymes or acids. This process is known as starch hydrolysis.


Fermentation: The glucose is then fermented using yeast or bacteria to convert it into ethanol. The fermentation process typically takes several days to complete.


Distillation: The fermented liquid is then distilled to separate the ethanol from the water and other impurities. This produces a high-purity ethanol product that can be used for various applications.


Purification: The distilled ethanol is then purified to remove any remaining impurities and improve its quality. This can be done using various methods such as distillation, filtration, or adsorption.


Dehydration: The purified ethanol is then dehydrated to remove the remaining water and increase the alcohol content to around 96%.


Storage and packaging: The final product is then stored in drums or tanks and packaged in bottles or drums ready for sale or further processing.
