Don’t just sell raw cassava; transform it into profit. This guide will show you how to turn 1 ton of raw cassava into over 250 kg of garri, potentially boosting your income by up to 400%. Cassava processing is a straightforward path to building a sustainable and highly profitable business in Nigeria.
What Are the Most Common Questions about Cassava Processing?
Before we dive into the details, let’s answer some key questions about cassava processing.
- Is cassava processing profitable? Absolutely. Processing raw cassava into products like garri can increase its value by 200-400%, offering significantly higher profit margins than selling raw tubers.
- How much garri will 1 ton of cassava produce? You can expect around 250 kg of garri from 1 ton of fresh cassava, based on a typical conversion ratio of about 25%.
- What is the fufu yield from 1 ton of cassava? The yield for fufu flour is slightly less, producing approximately 200-270 kg from one ton of fresh cassava.
- How many days should cassava be soaked for fufu? The fermentation process for fufu typically takes 3 to 5 days.
- How much is 50 kg of garri? A 50 kg bag of garri sells for ₦45,000 to ₦75,000, meaning 1 ton can generate a revenue of ₦900,000 to ₦1,500,000.
How to Ensure a Golden Harvest for Better Cassava Processing
Your profits don’t start at the factory; they begin the moment you plant the first stem. The quality of your final product is a direct reflection of choosing the best cassava variety for your region. High-yielding, disease-resistant varieties like TME 419 have high starch content, making them perfect for cassava processing.
My Personal Tip: Varieties like TMS 30572 are great for garri due to their high dry matter. For fufu, TME 419 works well as it ferments quickly and gives a smoother texture. Selecting the right variety for your desired end product is the first step to boosting your profits.
How to Process Cassava into Garri: A Step-by-Step Guide
Garri is a staple food across West Africa. While traditionally labor-intensive, machinery can make cassava processing faster and more scalable.
Step 1: Harvesting and Preparation
First, you’ll need to harvest and select mature, healthy, and firm cassava tubers. Next, the tubers must be peeled and washed. This is a crucial step for removing the outer layers, which contain cyanogenic glucosides.
Profitability Tip: Investing in a mechanical peeler is a great idea. Manual peeling can waste up to 30% of your product, while a machine cuts that loss to just 10-15%. A small-scale peeler can process over 1,000 kg a day, a task that would take a team of five people to do manually, drastically reducing labor costs.
Step 2: Grating and Fermentation
The washed and peeled cassava is then grated into a fine mash. This mash is packed into porous bags and left to ferment for one to three days. This lactic acid fermentation process gives garri its classic sour taste and is critical for HCN removal. The bags are then placed under a press to remove excess water.
Profitability Tip: A motorized, stainless steel grater produces a finer, more uniform mash. This leads to higher quality garri that can command a premium price—often 15-25% higher than garri from manual graters. Stainless steel also prevents contamination and rust, which is key for food safety and brand reputation.
Step 3: Sieving, Frying, and Cooling
After dewatering, the cassava cake is broken up and sieved. The sieved grits are then fried or roasted in a large, shallow pan. A mechanized rotary fryer provides a more controlled and efficient process. For yellow garri, a small amount of palm oil is added during frying. Finally, the garri is spread out to cool before being packaged for sale.
How to Process Cassava into Fufu: A Step-by-Step Guide
Fufu is a soft, dough-like food made from fermented cassava. This is another popular cassava processing method.
Step 1: Peeling and Soaking
The cassava tubers are peeled and washed and then cut into chunks and submerged in a container of water. They are left to ferment for three to five days, or until soft. This is crucial for cyanide reduction.
Profitability Tip: Proper sanitation and a controlled fermentation process are key. Spoilage at this stage means a complete loss of the batch. Make sure your water is clean an your containers are hygienic.
Step 2: Pulping and Dewatering
The fermented cassava is then pulped, traditionally by pounding in a mortar. For larger batches, a grinding machine is a significant improvement, as it can pulp 500 kg in under an hour, a task that would take a team several hours. The pulp is then washed and dewatered using a press or a plate-frame filter press.
Step 3: Cooking and Packaging
The dewatered fufu paste is cooked in a pot until it becomes a smooth, thick, off-white dough. For commercial sale, the cooked fufu can be wrapped in portions. Alternatively, the dewatered paste can be dried using industrial drying technology to produce fufu flour, which has a longer shelf life.
Detailed Comparison of Cassava Processing Methods
Choosing the right cassava processing method depends on your goals, capital, and market. Each method has a distinct impact on your final product. HQCF (High-Quality Cassava Flour) is a modern approach that opens up industrial applications.

The Economics of Cassava Processing: A Path to Higher Profits
This section is dedicated to a cassava processing profitability analysis and other cassava products. Processing cassava isn’t just about making a product; it’s about seizing a lucrative opportunity with high, steady demand. While selling raw cassava is one option, processing it unlocks a whole new level of income. The conversion yield is massive. Roughly 4 tons of fresh cassava roots will produce 1 ton of garri. This means 1 ton of fresh cassava will give you about 250 kg of garri. With market prices for a 50kg bag of garri ranging from ₦45,000 to ₦75,000, you can generate a revenue of approximately ₦225,000 to ₦375,000 from your 250 kg. That’s a gross profit of between ₦100,000 and ₦250,000 before accounting for labor and other costs. This is a significantly higher return than selling the raw tubers.
A Mini Case Study: Mrs. Uche’s Story
Mrs. Uche from Enugu used to sell her family’s cassava harvest raw at the local market. The prices were low, and a good portion of her harvest would spoil before she could sell it. After hearing about the potential of cassava processing, she took a small loan to buy a motorized grater and a press. She started by processing just 200 kg of her cassava a week.
Initially, her manual labor costs were high, but her family helped out. Within a few months, the quality of her garri earned her a reputation, and she was able to sell her product at a premium. She reinvested her profits, buying a rotary fryer to save on firewood and labor. Today, she’s a local success story, consistently producing 500 kg of garri a week and earning more than triple her old income.
Expert Perspectives on Profitability
This isn’t just my opinion; it’s a well-documented fact. Experts and organizations have weighed in on the immense opportunities within the cassava value chain.
“In both Ghana and Nigeria, cassava cash incomes were the highest among farms with access to mechanized cassava processing equipment for the preparation of gari.” — Food and Agriculture Organization (FAO), ‘The Cassava Transformation in Africa’
This highlights how crucial mechanized equipment is for generating higher incomes for small-scale farmers and processors. A similar report from the International Institute of Tropical Agriculture (IITA) also emphasizes the economic benefits of processing.
