- Cashew nut shell liquid
is a by-product of the cashew industry. The shell of the nut contains a
dark reddish brown viscous liquid. It is called the cashew nut shell
liquid
- The CSNL
content of the raw nut varies between 20 and 25 percent.
-
There are more than 200
patents for its industrial application, in particular, its use as raw
material for phenolic resins and friction powder for the automotive
industry
- Cashew nut shell liquid
(CNSL) consists unsaturated phenolic
compounds, anacardic acid (90%) and cardol (10%) with minor amounts of
2-methyl cardol.
- Three
different methods used in extracting cashew nut shell liquid
from cashew nuts are mechanical, roasting and solvent extraction.
The processes used are mainly hot-oil and roasting in which the CNSL
oozes out from the shell.
- CNSL finds a wide array
of applications such as friction linings, paints & varnishes,
laminating resins, rubber compounding resins, cashew cements,
polyurethane based polymers, surfactants, foundry chemicals and
intermediates for chemical industry.
- CNSL exhibits potent
antibacterial activity against Gram-positive bacteria and weak
antifungal activity against molds. Traditionally it is to treat such
scurvy, sores, warts, ringworm and psoriasis. It could be a source of
new antimicrobial agents, especially for use in foods and cosmetics.
-
The production
potential for the product is very high. The total production of raw
cashew nut in the country could be as much as 2 lakh tonnes and at 10%
recovery by weight, the production potential for C.N.S.L is as much as
20,000 tonnes.
- The use of this oil by
indigenous industry is at present limited, however an upward trend has
been noticed. U.K. USA and Japan were the large scale buyers of this
commodity until recently but due to changes in technology, UK and USA
have stopped buying this product from India. At present, Japan and
Republic of Korea buy a sizeable quantity of this commodity from
India.
- Cashew nut processing
industries are one of the promising sectors producing valuable commodity
exported to Gulf, European and Western countries.
- India has the
potential to produce about 150,000 tonnes of CSNL a year. But only 45000
tonnes of CSNL are currently produced
- The production in
India is limited to Karnataka, Goa, South Arcot & Kanyakumari districts
in Tamil Nadu and Kollam in Kerala.
- Technology is very
well established and is available from Machinery suppliers
- After extracting the
CNSL, the cashew nut shells can be burned to provide heat for the
decorticating operation or can be used in the manufacture of
agglomerates. Together with the testa, it may be used either in the
manufacture of dyestuff or to provide durability to hammocks and fishing
lines.
- Investment:
Medium – High investment. (Investment in Plant and Machinery is in the
range of $ 50000 - $150000 depending upon the capacity
- The main markets for
CNSL are the United States, the European Union (mainly the United
Kingdom)Japan and the Republic of Korea. Together these account for over
ninety percent of world trade, most of which is supplied by India and
Brazil.
