Cassava Processing Plant Project Report (DPR) 2026

What is cassava processing?

Cassava (Manihot esculenta), also called tapioca or manioc, is a starchy tropical root that spoils within two to three days of harvest, so it has to be processed close to the farm. A cassava processing plant turns fresh roots into shelf-stable products such as dried chips and pellets, flour, starch, gari and tapioca pearls. This page models an integrated unit that sends most roots to a tapioca pearl (sago) line and the rest to a chip-and-flour line, and sells the fibrous residue as animal feed. Native starch for paper, textile and pharmaceutical buyers is a different business and is not the focus here.

Trade codes differ by product: tapioca pearls fall under HS 190300, tapioca prepared from starch in flakes, grains or pearls; cassava flour under HS 110620; and dried chips and pellets under HS 071410. Pearl makers sell two broad types, small sago pearls cooked as porridge or snacks and larger pearls used in bubble tea and desserts, each graded by size. Buyers include food wholesalers in Asia, bubble tea and dessert chains in East Asia and North America, snack makers, and gluten-free bakeries that use cassava flour as a wheat substitute.

Cassava market overview and global demand

Credence Research valued the global cassava market at USD 174.94 billion in 2024, or about USD 182 billion in 2025 based on that figure and its forecast CAGR of 4.2% through 2032. World root output reached about 315 million tonnes in 2021, up from 286 million in 2017, according to a 2024 study in Discover Agriculture. Nigeria led with about 63 million tonnes, followed by the Democratic Republic of Congo, Thailand, Ghana and Brazil, and Africa grew about two-thirds of the total, mostly for local food such as gari and fufu.

Cassava trade is concentrated in Asia, where Thailand is the largest exporter, with about 35% of world cassava export value in 2021, according to the same study, and Vietnam, Cambodia and Laos supply both finished products and roots to Thai mills. China takes nearly all traded chips. Thai exports of chips and pellets reached 4.4 million tonnes in January to November 2025, more than double the year before, and starch exports reached 3.4 million tonnes in January to October 2025, nearly half of it to China.

Tapioca pearl demand comes from two main pools. India, which grew 5.94 million tonnes of cassava in 2023, consumes sago during fasting seasons and makes most of it in Tamil Nadu, while bubble tea chains drive demand for larger pearls in East Asia, North America and Europe. Cassava flour sells to snack makers and bakeries tracking wider gluten-free flour demand.

Cassava manufacturing process for tapioca pearls and flour

The pearl route is a wet process. Trucks bring roots from surrounding farms, and each load is tested for starch content at the gate, because mills in Thailand and India pay on starch content rather than weight alone. The main steps are:

• Washing and peeling. Rotary drum washers remove soil and the thin outer skin.
• Rasping. A high-speed rasper grinds the roots into pulp and releases starch granules.
• Sieving. Brush or vibrating sieves separate starch milk from fiber, which is pressed and sun-dried as feed pulp.
• Settling. Starch milk settles in tanks or passes through hydrocyclones. The wet starch cake can be stored for weeks, which keeps the pearl line running after the harvest ends.
• Pearl forming. Partly dried starch is broken into granules, rolled into pearls in a gyrating globulator and sized on screens; bubble tea pearls are usually made larger and may be colored or flavored.
• Gelatinizing and drying. Pearls are partly cooked in roasting pans or ovens, dried on concrete yards or in dryers, then polished and graded.

The flour line is a dry route. Peeled roots are sliced into chips, dried to below about 12% moisture in a mechanical dryer, milled in a hammer mill and sifted, giving roughly 1 tonne of flour from 4 tonnes of roots. Food-grade flour needs fast drying after slicing to keep the color white and microbial counts low, which is why yard drying alone suits only feed-grade chips.

Recovery from each tonne of roots decides profit. A survey of ten sago factories recorded 18.6% pearls and 3.9% dry pulp from root weight, with water use of about 4.5 cubic meters per tonne of roots. Hydrocyclones with water recycling can cut that water use by 40–50%. The effluent carries a heavy organic load, so modern units route it to anaerobic digesters, and the biogas replaces part of the firewood burned for roasting and drying.

Cassava plant setup cost

For an integrated unit crushing 100 tonnes of fresh roots a day, 80 tonnes to tapioca pearls and 20 tonnes to flour, total capital cost is estimated at USD 0.9–1.5 million at 2026 prices for a South or Southeast Asian site. The range scales a 2017 published survey of Indian sago units, which reported capital outlays of about USD 0.37–0.57 million at today's exchange rate with land at 33–37% and machinery at 30–40% of the total, to current prices. It then adds a flour line, an effluent plant with biogas digesters and a working capital margin that older units did not carry. A U.S. or EU build would cost more, mainly for land, civil works and labor.

Worked example of one row, land. A pearl unit needs more land than its machinery suggests because pearls and pulp are dried on open concrete yards. The model assumes 5 acres at an assumed USD 35,000–50,000 an acre for a rural or industrial-park site in South or Southeast Asia, or USD 175,000–250,000, about 18% of the mid-case CapEx. U.S. and EU industrial land usually costs more per acre, and a site without yards must add mechanical dryers and the fuel to run them.

Civil works, about 24% of CapEx, cover the process shed, settling tanks, drying yards and a warehouse large enough to hold several months of stock before peak demand. Plant machinery takes about 30%, effluent treatment and biogas about 10%, utilities and electrical about 6%, pre-operative costs and contingency about 4%, and the working capital margin about 8%. Working capital runs heavy because mills pay farmers on delivery during the harvest but sell much of the year's sago into seasonal demand peaks.

On the operating side, fresh roots dominate at about 82% of annual cost in the base case, followed by labor for peeling, yard work and bagging at about 7%, firewood and power at about 5%, and maintenance, packing, administration and selling for the rest. A USD 10 a tonne rise in root price that product prices do not follow cuts gross margin by roughly 8–9 percentage points, which is the single largest risk in the model.
