Regional Research Laboratory(RRL- Jorhat)
The Regional Research Laboratory (RRL) , Jorhat was established in the year 1961 as one of the multidisciplinary laboratories of Council of Scientific & Industrial Research(CSIR) under its Chemical Science Group of laboratories. Its major thrust of R&D activities has been to develop indigeneous technologies by utilising the immense natural wealth of India. The North Eastern Region of the country being bestowed with an abundance of material resources like petroleum, natural Gas, Minerals, Tea as well as aromatic and Medicinal plants and hence the laboratories was targeted to undertake research for development of Know-How for a wide a range of industries and extension works. Over the years, the laboratory has generated more than 100 technologies in the areas of Agrotechnology, Biological and Oil Field Chemicals of which about 40% were of commercial success culminating in setting up of various industries through out the country. The laboratory also developed expertise in the areas like Natural Products Chemistry, drug and drug intermediates, VSK cement, Plant Technology, Agro-technologies, Petroleum Microbiology and Petrochemicals , Crude oil transportation, Paper and Paper Products, beneficiation Chemicals, ecology and environmental studies, Geotechnical investigations, foundation design engineering, soil and building materials etc. The annual turn over of the products produced with RRLtechnologies within the country is estimated to be Rs. 110 crores.
SOME OF THE SIGNIFICANT ACHIEVEMENTS :
Development of know-how for' Arteether', a potent new generation anti-malarial drug active against Chloroquin resistant malaria strains. The know-how has been transferred to M/s FDC Ltd., a Bombay base pharmaceutical company, for commercial production.
Development of Vertical Shaft Kiln (VSK) for mini cement plants. Currently 35 mini cement plants are in operation in the country based on RRL-Jorhat technologies. A modified VSK technology for 30,000 TPA plant has also been developed to cater to the national and international needs.
Development of a series of pour point depressants for transportation of high waxy crude oils.
Development of oil field chemicals/materials like high and medium-strength cc,propants,chrome free lignites, oil-well formation stabilizer, etc.
Development of
agro-technologies for important medicinal and aromatic plants.
The laboratory's contribution to extensive cultivation of citronella grass and extraction
of oil have led to the establishment of a major citronella based agro- industry in the
North-eastern region. The production of citronella is about 500 tonnes and this has
generated employment for 22,000 persons in the rural sector alone
Development and
introduction of Agro-technologies for mushroom cultivation and
popularisation of several protein-rich edible mushroom varieties in different areas of
North-East India.
Process development for pesticides viz. Phosphamidon, Quinalphos and Chlorfenvinphos, isolation and characterisation of compounds of plant origin having insecticidal and antifeedant properties
Process development for speciality papers and boards including thermographic paper, carbon less copy paper, direct copy paper, carbon paper, gummed paper tape and ceiling boards
Development of a new process for utilisation of Banana plants for production of fibbers useful for making twines and fabrics in the conventional jute processing machines and also for making Eco-friendly products like Carpets, Doormats, Bags, Flower vase, Table mats, Purse, Flower basket, Wallhangings,Shopping bags, etc.
Multiplication of some medicinal perfumery and endangered plant species by tissue culture
Establishment of an ecology park named North-East Ecology Park (NEEP) and introduction of several important medicinal perfumery and endangered plants growing wildly in the North-Eastern states. NEEP will act as a gene park-cum- research park for plant breeders and biotechnologists
Establishment of a network of digital 3D seismic station along with a Central Recording Observatory equipped with remote dial-up facility for on-line data transmission and processing.
