Cassava Chips and Pellets: Uses, Production, Trade & Market Opportunities

by

From West African farms to European feed mills and Asian ethanol plants, cassava chips and pellets have quietly become one of the most traded agricultural commodities in the world, worth billions of dollars annually.

Cassava chips and pellets are processed forms of cassava root that have become indispensable in global commodity trade. Dried and compacted for easy handling, they serve as raw materials in animal feed, bioethanol production, starch manufacturing, and industrial fermentation. As demand for affordable, starch-rich feedstocks grows across Asia, Europe, and beyond, cassava processing has turned into a multi-billion-dollar industry. This article covers what cassava chips and pellets are, how they are produced, where they are traded, and the economic opportunities they offer to farmers, processors, and exporters worldwide.

What Are Cassava Chips?

Cassava chips, different from fried cassava chips, are dried, flat or irregular pieces of cassava root that have been peeled, cut, and dehydrated to reduce moisture.

They represent one of the earliest and most common forms of cassava processing practiced at both smallholder and commercial scales.

Unlike fresh cassava roots, which contain 60 to 70 percent moisture and deteriorate rapidly after harvest, cassava chips have a moisture content of 12 to 14 percent. This low moisture level gives them a shelf life of six to twelve months when properly stored, making long-distance trade viable.

Chips vary in thickness from 5 to 15 millimeters and can be sun-dried or mechanically dried depending on the scale of production. Their common industrial specifications include:

  • Moisture content: 12 to 14 percent maximum
  • Starch content: 65 to 70 percent on a dry weight basis
  • Sand/silica content: below 2.5 percent
  • Free from visible mold, insect infestation, and aflatoxin contamination
  • Color: cream to light brown, indicating proper drying without burning

What Are Cassava Pellets?

Cassava pellets are cylindrical or barrel-shaped compressed forms of cassava meal or flour produced through a pelletizing process. They are a step beyond chips in terms of processing, offering a more standardized, dense, and uniform product suited for bulk international trade.

Where chips are simply dried and cut pieces, pellets are ground into meal, conditioned with steam or water, and then extruded under pressure through a die to form small cylinders, typically 6 to 8 millimeters in diameter. The resulting pellets are denser, easier to handle in automated feed systems, and less prone to dust generation than loose chips or meal.

The advantages of pelletization include:

  • Higher bulk density, reducing shipping volume and freight costs per unit weight
  • Better flowability in automated storage and feed delivery systems
  • Lower moisture absorption during storage compared to loose meal
  • Consistent nutrient and starch content in every batch
  • Reduced risk of contamination from dust and foreign matter

For these reasons, pellets are strongly preferred in the European feed and biofuel import markets, where uniformity and handling efficiency are critical for large-scale operations.

How Cassava Chips Are Produced

Raw Material Selection

Production begins with selecting fresh cassava roots of the right maturity, typically harvested between 9 and 18 months after planting. Roots are inspected for disease, rot, and physical damage. High-starch varieties are selected for better product yield.

Cleaning and Peeling

Roots are washed to remove soil and field debris, then peeled either manually or using drum peelers. Complete peeling is necessary because the outer brown and inner white peel layers contain higher fiber and lower starch content, which reduce quality if retained.

Chipping Process

Cleaned roots are fed into motorized or hand-operated chippers that cut them into uniform slices. Chip thickness affects drying speed, with thinner chips drying faster but being more fragile and prone to breakage.

Drying Methods

Drying is the most critical step in chip production. The two main approaches are:

  • Sun drying: Chips are spread on concrete floors, tarpaulins, or raised drying beds and dried under sunlight over 2 to 4 days. Cost is low but the process depends heavily on weather and can result in uneven moisture distribution.
  • Mechanical drying: Flash dryers, rotary drum dryers, or forced-air systems reduce drying time to a few hours and allow moisture content to be controlled precisely. These are used in commercial-scale operations with consistent export requirements.

Quality Control and Storage

Dried chips are screened to remove fines, stones, and undersized pieces. Samples are tested for moisture content and starch content before bagging. Properly dried chips are stored in well-ventilated warehouses or packed in polypropylene bags for transport.

How Cassava Pellets Are Manufactured

Preparation of Cassava Chips or Meal

Pellet production uses either dried cassava chips or fresh cassava mash. When chips are used, they are first ground into a coarse or fine meal using hammer mills or disc mills. The particle size of the meal affects how well pellets bind together.

Grinding and Conditioning

Ground cassava meal is conditioned by passing it through a steam conditioner or by adding small amounts of water. This raises the temperature and moisture of the meal slightly, making the natural starches gelatinize partially. Gelatinization acts as a natural binder, helping pellets hold their shape without the need for artificial additives.

Pelletizing Process

Conditioned meal is fed into a pellet mill, where a rotating die and press rollers force the material through holes of a specific diameter. The pressure and heat generated at the die cause further starch binding. Pellets exit the die as continuous cylinders and are cut to length by a knife.

Cooling and Drying

Freshly formed pellets are hot and contain slightly elevated moisture. They pass through a counterflow cooler that brings their temperature down and reduces moisture to the target level of 12 to 14 percent. Adequate cooling prevents condensation and mold growth during storage.

Quality Standards for Export Markets

Export-grade cassava pellets must meet buyer specifications, which commonly include:

  • Moisture: 12 to 14 percent maximum
  • Starch content: 65 to 70 percent minimum
  • Crude fiber: 5 percent maximum
  • Aflatoxin: below 10 parts per billion (EU markets require below 10 ppb for feed use)
  • No foreign matter, mold, or unusual odors

Industrial Applications of Cassava Chips and Pellets

Animal Feed Manufacturing

The single largest use of cassava chips and pellets globally is as an energy ingredient in compound animal feed.

Livestock feed: Cattle and ruminants can utilize cassava chips effectively as an energy source. The starch content provides fermentable carbohydrates in the rumen, supporting growth and milk production.

Poultry feed: Cassava meal is incorporated into broiler and layer diets at levels of 10 to 25 percent as a substitute for maize, providing a cost-effective energy source without significantly affecting feed conversion ratios.

Swine feed: Pigs digest cassava starch well, and cassava meal is used in grower and finisher diets at 15 to 30 percent inclusion levels, reducing diet cost when maize prices are high.

Aquaculture feed: Fish and shrimp feed manufacturers use cassava starch both as an energy ingredient and as a natural binder in extruded pellets, replacing synthetic binders.

Energy source in feed formulations: With a metabolizable energy value of approximately 3,300 kcal per kilogram on a dry matter basis, cassava meal ranks close to maize and is competitive whenever cassava prices fall below corn on an energy-cost basis.

Bioethanol Production

Cassava chips and pellets are a leading feedstock for ethanol distilleries in Asia, particularly in China and Thailand.

Dried cassava products are preferred over fresh roots in large-scale ethanol plants because they store easily near the distillery, allow year-round production independent of harvest season, and have a consistent starch concentration that simplifies fermentation planning.

One ton of cassava chips with 65 percent starch content yields approximately 380 to 400 liters of ethanol, making it a commercially viable feedstock for renewable fuel production under government biofuel mandates in several countries.

Starch Manufacturing

Dried cassava chips and meals serve as raw materials for wet-milling starch extraction plants. Starch processors sometimes use dried feedstocks when fresh root supply is limited or when the processing facility is located far from growing areas.

The starch extracted is used in food manufacturing, paper and textile sizing, adhesives, and pharmaceutical applications. Industrial-grade cassava starch is one of the most widely traded starches globally.

Industrial Fermentation

Beyond ethanol, cassava chips and pellets are used as carbon and energy sources in fermentation processes, including:

  • Organic acids: Citric acid, lactic acid, and succinic acid production using cassava starch as a fermentation substrate
  • Amino acid manufacturing: Lysine, glutamate (MSG), and threonine production at large fermentation plants, particularly in China
  • Enzyme production: Cassava starch provides the carbon source for microbial enzyme synthesis in industrial biotechnology
  • Biotechnology applications: Emerging biorefinery concepts use cassava as a feedstock for bioplastics, biopolymers, and biochemicals

Cassava Chips and Pellets in the Global Feed Industry

Feed manufacturers in Europe and Asia rely heavily on cassava products as energy substitutes for maize and wheat in compound feeds. The primary driver is price: cassava chips and pellets are generally 15 to 30 percent cheaper than maize on an energy-equivalent basis during periods of grain price increases.

Nutritionally, cassava meal delivers energy through starch but contains limited protein (2 to 3 percent crude protein), requiring supplementation with protein-rich ingredients like soybean meal. This means cassava functions as an energy replacer rather than a complete feed ingredient.

Compared with corn, cassava meal has similar digestible energy but lower protein, lower fat, and slightly higher fiber. Feed formulators use least-cost formulation software to determine the exact cassava inclusion level that minimizes diet cost without compromising animal performance.

Economic benefits for feed producers include lower ingredient costs, supply chain diversification away from volatile grain markets, and access to a global supply chain anchored in major cassava-producing countries.

Export Markets for Cassava Chips and Pellets

Major Exporting Countries

Thailand is the world’s dominant exporter of cassava products, accounting for roughly 50 to 60 percent of global cassava chip and pellet exports. Nigeria, Ghana, Vietnam, Cambodia, and Indonesia are also significant exporters, with growing export capacity.

  • Packaging and storage conditions: Poorly ventilated storage leads to moisture reabsorption and mold growth
  • Compliance with buyer specifications: EU-bound cassava pellets must comply with EU feed legislation on aflatoxin, heavy metals, and pesticide residues

Economic Opportunities in Cassava Chip and Pellet Production

Small-Scale Processing Businesses

Small operators with access to cassava-growing areas can establish village-level chipping and sun-drying operations with relatively low capital investment. Solar dryers and small motorized chippers are available at modest cost and can increase profitability significantly over selling fresh roots.

Commercial Pellet Manufacturing

Larger investors can establish integrated processing plants that buy chips from smallholder networks, grind them into meal, and pelletize for export. A well-run pellet plant serving export markets can generate strong margins when cassava raw material prices are low relative to world grain prices.

Export-Oriented Production

Producers near ports can position themselves for direct export by achieving consistent product quality, obtaining phytosanitary certifications, and building relationships with commodity traders and feed manufacturers in Asia and Europe.

Opportunities for Farmer Cooperatives

Cooperatives can pool cassava production to justify investment in shared chipping and drying equipment, enabling member farmers to sell chips at higher prices than fresh roots while reducing post-harvest losses.

Value Addition Compared to Selling Fresh Roots

Selling fresh cassava roots at farm gate prices gives the lowest return per kilogram. Converting roots to chips increases value by 30 to 50 percent, while pelletizing adds another 10 to 20 percent premium in export markets, depending on logistics costs and buyer requirements.

Challenges Facing the Cassava Chip and Pellet Industry

Despite its opportunities, the cassava processing sector faces real constraints:

  • Raw material supply fluctuations: Cassava yields vary with rainfall, disease, and soil conditions, leading to inconsistent chip supply
  • Drying and storage constraints: Weather-dependent sun drying results in variable moisture content, while proper mechanical drying requires capital investment
  • Transportation costs: Remote growing areas add logistics costs that reduce export competitiveness
  • Competition from corn and grains: When grain prices drop, cassava loses its cost advantage and demand softens
  • Quality consistency issues: Small-scale producers often struggle to meet the standardized specifications required by international buyers

Sustainability Benefits of Cassava Chips and Pellets

Processing cassava into chips and pellets offers meaningful sustainability advantages compared to leaving fresh roots unharvested or selling them locally:

  • Reduced post-harvest losses: Fresh cassava deteriorates within 24 to 72 hours of harvest; drying extends usability to months or years
  • Longer shelf life than fresh roots: Chips and pellets stored correctly can serve as a buffer stock against seasonal supply gaps
  • Efficient transportation and storage: Higher density and lower moisture content reduce transport weight and storage space per unit of starch delivered
  • Support for rural agricultural economies: Chip and pellet processing creates employment and income at the village and district level, retaining more value in producing communities
