- 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.
