SIGNIFICANT ACHIEVEMENTS
PRODUCTION OF COIRRET AND PITHPLUS - The extension of R&D technologies through Pilot Scale Laboratory(PSL) at the CCRI, Alappuzha for COIRRET (a bacterial cocktail to carry out faster retting of husk/fibres), PITHPLUS (a fungal spawn to convert coir pith into an organic manure) and Coir Pith Organic Manure[C-POM] fetches revenue of over Rs. 10 lakhs per annum. Production facility has also been created at the regional offices of the Board to meet the local requirements.
ZERO EFFLUENT PROCESS FOR BIO-BLEACHING AND SOFTENING - An eco-friendly formulation with zero effluent has been developed to treat the coir fibres and wrapping that for a period of 12 hours by which the fibres become softer and brighter and are amenable to spinning. The process has been demostrated in the industry successfully.
FULLY AUTOMATIC VERSATILE SPINNING MACHINE- A fully automatic four head spinning machine without using core thread has been developed for the first time using the novel technology of open end spinning by rotor and biochemically softened coir fibres. A single yarn doubling machine has also been developed to produce 2 ply coir yarns. The machine is capable of producing about 200 kgs of yarn of 160 runnage/8 hours by 2 workers. The machine has been demonstrated in the Indian International coir fair-2012 at Kochi and at IITF, New Delhi before the public. A new prototype is under development with much higher productivity with least moving parts.
PRODUCT DIVERSIFICATION – Biochemically softened coir fibres have been blended with other natural fibres to produce finer lightweight fabrics which have been used for making Janatha Mattresses, UV protective umbrellas, Jackets, Conference bags, foot wares and upholstery etc.

1. RESEARCH EXPERIENCE
I. Quality Improvement of Coir Fibre
>> Initiated research under the scheme “Process Improvement in Extraction of White Fibre” with the objective to reduce the drudgery involved and extended time of retting of coconut husks to improve the extraction process of coir fibre.
  • >> Developed a bacterial cocktail “Coirret” for reducing the retting time to three months and yield retted quality fibre.
>> Carried outdemonstrations in different regions of Kerala and a bulk treatment conducted on 100,000 husks at Kayamkulam.
  • >> Coirret could ret machine extracted fibre in tanks in 72 hours and bulk demonstrations were conducted at Poochakkal, Cherthala on the application of Coirret in tanks.
>> Application of Coirret could reduce the phenol content in the effluent by 70%.
>> Further studies on Coirret mixed with a conditioner led to the development of a cost effective, zero waste Biochem treatment on coir fibre which yields retted quality fibre in 12 hours.
>> Thus a drudgery and pollution free, cost effective Coirret technology was developed by my research work at CCRI for which I have been recognized by Coir Board.The invention has been granted Patent No 202787 of 06-04-1998.
II. Effluent Treatment
>> Coir fibre extraction involves soaking of coconut husks & coir fibre in tanks which leads to generation of large quantities of coir retting effluents which is released in the environment causing pollution.
>> I have carried out detailed analysis on the chemical constituents of the treated water and developed a cost effective treatment after which the effluent can be recycled.
>> The combination of this technology with the Coirret treatment led to recognition by the National Research Development Corporation, Government of India in 1999. The invention has been granted patent vide 746/MAS/98 dated 6th April 1998.
III. Utilisation of Coir pith
>> Fibre extraction from coconut husk leads to generation of coir pith which is released in large quantities and accumulates in the environment causing land pollution.
>> In order to solve the problem of accumulating coir pith the technology of composting coir was initiated by setting up of a laboratory for production of Coirret and Pithplus,the fungus for composting coir pith, in the Microbiology Department in 1994 which continues to cater to the coir entrepreneurs till date.
>> The production of the fungus was improvised by UV sterilsation and packaging in polybags making the composting technology user-friendly and it was given a brand name of Pithplus& its production was streamlined to meet the demand from the coir industry.
>> The production of coir pith organic manure (C-POM) was also initiated by the Laboratory.
>> Today this laboratory caters to the requirement of Pithplus to coir entrepreneurs in south India as well to farmers in north India such as Indore who wish to use the coir pith organic manure as a fertilizer.
IV Setting up of test facilities for coir pith to facilitate its export
>> Extending the Pithplus for composting of coir pith led to coir entrepreneurs requesting for assistance to determine whether the pith was composted or not.
>> I had initiated the testing of coir pith for its nutrient parameters viz nitrogen, phosphorous and potassium and also its physical properties such as pH, EC etc.
>> The Microbiology Department started receiving a large number of samples of raw & composted coir pith samples which were tested in the laboratory and the status of the nutrients in the samples furnished to the entrepreneurs at a cost which fetched revenue to Coir Board.
Phytosanitary Testing:
>> I had initiated the testing of phytosanitary parameters in coir pith and trained the scientific assistant and project staff to carry out the microbiological tests which today successfully cater to the requirement of coir exporters to test the coir pith samples representing their consignment and issue the phytosanitary test reports which facilitates export.
>> Australian Quarantine Inspection Service (AQIS) has recognized this testing lab which continues to cater to the coir industrialists in India.
V Interdisciplinary research activities in Microbiology Laboratory
Lignosulphonates from coir pith
>> The presence of lignin in high quantities suggested the extraction of lignin in coir pith as a source of lignosulphonates.
>> I have initiated the laboratory scale extraction studies and initially obtained and dispatched 100 liters of the extracted liquid lignosulohonate to Dapodi in Pune which had facilities for bulk spray drying.
>> The spray dried material was analysed and observed to have potentials for application as an expander in lead acid batteries and oil well drilling.
>> Collaborative research studies with the Central Electro-Chemical Research Institute (CECRI), Karaikudi could confirm the findings.
Extraction of nanocellulose from coir fibre
>> The abundantly available renewable biomass coir can be a cost effective source for nanocellulose  which has immense applications in the biomedical industry.
>> Nanocellulose could be successfully   extracted from coir pith under laboratory conditions and it is our endeavor to develop a cost effective method for extraction of nanocellulose from coir pith.
Extraction of biofuels from coir pith
>> Biofuels like cellulose ethanol are being produced by growing corn and other feedstock plants to yield cellulose which can be hydrolysed to sugars and the fermented into cellulose ethanol.
>> Coir is a raw material produced throughout the year and can be a potential resource for energy generation.
>> Pilot scale studies have yielded successful results for extracting ethanol from coir pith.
>> The fast pyrolysis technology for extraction of bio-oils from coir pith has also yielded encouraging results under laboratory conditions and works are being conducted under my guidance at CCRI to set up a pilot scale bioreactor for production of bio-oils from coir waste.
Utilisation of tender coconut husk
>> Research under a project funded by the Coconut Development Board could lead to finding use of the tender husk as a source of valuable organic manure, handmade paper, and particle boards thereby solving its disposal problems.
>> A second project funded by the Coconut Development Board could lead to finding diversified uses of diseased coconut wood. Cellulose, microcrystalline cellulose, lignosulphonates and particle boards could be produced from the diseased coconut wood.
2. DEVELOPMENT
>> Process for reducing the period of retting of coconut husk using COIRRET.
>> Process for the treatment of coir retting effluents.
>> Process for preparation of organic manure from coir pith using PITHPLUS.
>> A modified process viz. BIOCHEM for treatment of mechanically extracted coir fibre to make it suitable for spinning on mechanised spinning machine.
>> A process for on-site composting of accumulated coir pith hillock
>> A process for extraction of lignosulphonates from coir pith
