Cashew Nut Shell Liquid (CNSL) Extraction Plant, Oil Expeller
Cashew nut shells contain 20 – 25 % oil content. After pressing, a residual oil of less than 10 – 12 % is left in the oilcake. The working principle of the Cashew Nut Shell Press is to forcefully push the cashew nut shell through the chamber by the action of the rotating screws.
CNSL has germicidal and fungicidal properties. The CAS Registry Number of CNSL is 8007-24-7. Naturally occurring cashew nut shell liquid contains mainly four components – cardanol, cardol, anacardic acid and 6-methyl cardol. The chemical structures of these compounds are shown in the following Fig. 1.
Cashew Nut Shell Liquid: A Promising Green Fuel
1. When extracting cashew nut shell liquid from cashew nuts, three basic techniques are typically used. The roasting method, the hot oil bath method, and using a solar cooker are the three options. In addition to removing the corrosive CNSL, roasting also renders the shell brittle, which speeds up the breaking process.
In Nigeria, cashew nuts export has been estimated to be approximately 7–8% of the non-oil export revenue with a postulated export value ranging from 25 to 35 million US Dollar per annum (4). Cashew farming and its nut processing activity provide job and livelihood for women and small-scale farmers in Nigeria (5, 6).
Utilizing cashew nut shell liquid for the sustainable production
The most widely used technique for the synthesis of biodiesel from non-edible oil, such as cashew nut shell liquid as well as animal fats, is transesterification (Abdul Hakim Shaah et al., 2021). In the transesterification reaction, reactants—oil triglycerides and alcohol—are reacted in the presence of a catalyst ( Fig. 7 ) ( José et al., 2020 ; Sundaramahalingam et al., 2021 ).
Cashew nut shell, a by-product of the cashew industry, is an embodiment of a useful chemical serving as a raw material for the petrochemical industry. Cashew (Anacardium Occidentale L.), a well-known species of the Anacardiceae family [1], is a tropical plant (shrub) found within the region between 23 ° N and 23 ° S of the equator.

Recent Trends of Cashew Nutshell Liquid: Extraction, Chemistry,
Studies on the use of cashew nutshell liquid (CNSL) as a source of raw material for diverse chemical industry applications are well documented. The liquid is extracted from the nutshell and can be further purified to several chemical constituents such as anacardic acid, cardanol, cardol, and 2-methyl cardol.
A valuable edible nut is the cashew nut. It produces two “oils”; one of them is known as Cashew Nut shell Liquid (CNSL) and is located between the seed coat (or pericarp) and the nuts (Akinhanmi et al. 2008). Many researchers have offered explana-tions for how cashew nut shells can be used to extract oil. CNSL is the extraction of cashew nut
- How to set up a cashew nut shell liquid (CNSL) extraction plant?
- Here we have listed some of the basic machinery required to set up a Cashew Nut Shell Liquid (CNSL) Extraction Plant In the Cashew Nut Shell Liquid (CNSL) Extraction Plant, the Cashew Nut Shell undergoes the following steps: Oil Extraction, Neutralization and Oil Storage. Cashew nut shells contain 20 ¨C 25 % oil content.
- What is cashew nut shell liquid?
- Cashew Nut Shell Liquid (CNSL) is a versatile by-product of the Cashew Processing Plant. The nut has a shell which is a soft honeycomb structure containing a dark reddish brown viscous liquid. It is called cashew nut shell liquid. It is often considered as the better and cheaper material for unsaturated phenols.
- How is cashew nut shell oil extracted?
- In the Cashew Nut Shell Liquid (CNSL) Extraction Plant, the Cashew Nut Shell undergoes the following steps: Oil Extraction, Neutralization and Oil Storage. Cashew nut shells contain 20 ¨C 25 % oil content. After pressing, a residual oil of less than 10 ¨C 12 % is left in the oilcake.
- What is the thickness of a cashew nut shell?
- The cashew nut shell is approximately 1/8 in. (0.32 cm) thick. The soft honeycomb matrix, in between the outer and inner shell, contains a dark brown liquid, which is known as cashew nut shell liquid (CNSL).
