Cashew Processing Plant Project Report (DPR) 2026

What is cashew processing?

Cashew processing turns the raw nut of the cashew tree (Anacardium occidentale) into the pale, kidney-shaped kernel sold as a snack and food ingredient. The kernel sits inside a hard, double-walled shell filled with cashew nut shell liquid, a caustic, phenol-rich oil that burns skin, so the nut cannot simply be cracked like an almond or a walnut. Processors first condition the shell with steam or heat, cut it open, then dry the kernel and remove its thin brown skin, called the testa, before grading.

In the Harmonized System, cashew nuts in shell fall under code 0801.31 and shelled cashew kernels under 0801.32. Kernels are graded by size and color, from large white wholes such as W180 and W240 to the widely traded W320 and W450, followed by butts, splits and pieces. Most go to roasters, snack packers, bakeries, confectioners and makers of plant-based dairy alternatives. Shells are a by-product that can be pressed for shell liquid or burned as boiler fuel.

Cashew market overview and global demand

Credence Research estimates the global cashew market at USD 7.97 billion in 2025 and expects it to reach about USD 10.07 billion by 2032, a 3.4% CAGR, as set out in its global cashew market report.

Raw nut supply has grown faster than processing capacity. The International Nut and Dried Fruit Council's March 2026 crop update estimated the 2025/26 world crop at about 6.38 million metric tons in shell, a record and roughly 19% above the prior season. Côte d'Ivoire leads with about 1.5 million tons, followed by Cambodia at 930,000 tons, India at 725,000 tons, Tanzania at 500,000 tons and Nigeria at 370,000 tons.

Shelling, however, remains concentrated in Asia. Vietnam imported about 3.12 million tons of raw nuts worth USD 4.66 billion in 2025 and exported about 798,000 tons of kernels worth more than USD 5.4 billion, keeping its place as the top kernel exporter. India processes both domestic and imported nuts and is also the largest consumer, at about 396,000 tons of kernels in 2024 by the council's figures, ahead of the United States at 174,000 tons and Germany at 56,000 tons.

African origins are trying to capture more of that value. Côte d'Ivoire processed about 36% of its 1.3-million-ton harvest in 2024 and targets 50% by 2030, and several West and East African governments now offer incentives for local shelling. A new origin plant gains cheaper nuts but competes with exporters and other processors for them at harvest.

Cashew processing plant manufacturing process

A cashew plant runs year-round on nuts bought in a short harvest window, so drying and storage come before any shelling.

• Receiving, drying and storage. Raw nuts are sampled for moisture and outturn, sun- or machine-dried to about 8–9% moisture and stored in jute bags in ventilated warehouses for up to a year.
• Cleaning and calibration. Nuts are cleaned of stones and debris and sorted into four to six size grades so that shelling blades match each nut.
• Steam conditioning. Each grade is steamed in pressure cookers fed by a shell-fired boiler for about 20–30 minutes, then cooled, which makes the shell brittle and limits shell liquid contamination of the kernel. Some plants use drum roasting instead.
• Shelling and separation. Automatic cutting machines or hand-pedal cutters split the shell, and vibrating screens and air separators pull kernels from shell pieces.
• Kernel drying and peeling. Kernels are dried at about 70°C for several hours to loosen the testa, humidified briefly to prevent breakage, then peeled by compressed-air machines, with workers finishing stubborn pieces by hand.
• Grading, sorting and packing. Kernels are graded by size and color, passed through optical sorters and metal detectors, and packed in vacuum or carbon dioxide-flushed tins or laminated bags, typically 50 pounds (22.68 kilograms) each.

Profitability rests on two figures, starting with outturn, measured in the trade as kernel output ratio, or pounds of kernel per 80-kilogram bag of raw nuts. Good West African and Cambodian lots test about 46–52 pounds, and actual plant recovery typically lands at 22–26% of raw nut weight after process losses. The second is the share of whole kernels, since splits and pieces sell at a deep discount to W240 and W320 wholes. Shells, about two-thirds of raw nut weight, fuel the boiler and kernel dryers or feed a shell liquid expeller supplying the cashew nutshell liquid market. Workers handling shells need gloves, because the liquid causes chemical burns.

Cashew processing plant setup cost

The cost model assumes a semi-automated plant that processes 10,000 tons of raw cashew nuts a year, running about 300 days at 85% utilization, or 8,500 tons. At 24% kernel recovery, that yields about 2,040 tons of kernels. Total project cost is estimated at USD 6–15 million for a greenfield site with a West African or South Asian cost basis, including a working capital margin. Sites in Vietnam's southern industrial parks, the EU or the U.S. cost more.

The range is anchored on disclosed costs of real plants. Valency International's 45,000-ton-a-year plant at Attinguié in Côte d'Ivoire, opened in January 2025, cost about 24 billion CFA francs, or roughly USD 40 million. Scaled down to 10,000 tons with a standard 0.65 capacity exponent, that points to about USD 15 million. Robust International's USD 20 million facility for a 15,000-ton plant at Toumodi scales to a similar figure, while a USD 7.48 million construction tranche for a 30,000-ton plant in Lagos points to leaner builds at the low end.

Buildings and civil works, led by raw nut warehouses, and plant and machinery take about 31% of CapEx each, working capital margin 24%, utilities and pre-operative costs 5% each, and land 4%.

Worked example, land: the plant needs about 3 hectares for a raw nut drying yard, warehouses holding up to half a year's nuts, a processing hall of about 4,000 square meters, a boiler house and truck access. At assumed industrial land rates of USD 5–20 per square meter, land costs USD 150,000–600,000. Serviced plots in Vietnamese or Indian industrial parks can cost several times more.

Raw nuts dominate operating cost at about 82–87% of the total. Overheads, freight and crop finance take about 6%, labor 5%, energy and utilities 2%, and packaging and maintenance 1% each. Because most nuts must be bought within three to four months, the plant needs seasonal crop finance well beyond the working capital margin in CapEx. In the Lagos deal, Afreximbank paired the construction tranche with a USD 13.25 million working capital line.
