  • Biofiltration for Industrial Odour Control
    NIIST undertakes a careful study of customer requirements before the design of the odour control system.
    Depending on VOC to be removed media is formulated to neutralise acids formed by bacterial action. This biofilter media has the ability to accommodate highly varying “puff” loads which is a common occurrence from may industrial sources. Bacteria are at the heart of a successful biofilter and a key factor is the growth of suitable microbial population. NIIST brings experience and internationally recognised competence in biological treatment systems to guarantee biofilter performance.

  • High Volume Flux Bonded Fly Ash Ceramic Technology for Building Components First of its kind in India, the process developed utilizes up to 80% by weight of fly ash with certain glass forming additives to red coloured building components such as bricks, pavements, tiles, glazed tiles etc. after firing in the range 850-9500C as in the case of clay products.

    The process is adaptable to the traditional brick and tile industry with appropriate mechanization and conserves upto 80% of natural clays and use up to 80% of fly ash. The cost calculations based on the pilot plant demonstration trials show that the price of the fly ash products will be in the similar range as clay products. The plant should be preferably in the premises of the thermal power plants and the process is suitable for pond ash and stored ash as also with dry fly ash. All machineries and the binders/additives are available in the country.

    Investment required : Total investment for a plant producing 60,000 bricks/tiles/glazed tiles: Rs.2-2.5 crore. Brick cost Rs.2.50-3.0 per piece, tiles at Rs. 4-5 per piece and glazed products Rs. 6-8 per piece.

    Returns /Benefit: 15-18% returns on investment over a period of 5 years.; Validation level: Pilot-scale.; IPR Status: Patented in India.

  • Clean Bioprocess for Natural Fibre ExtractionThis biological process yields superior quality fibres while shortening the processing time substantially. Here separation of fibres from their matrices is achieved by enzymatic cleaving of cementing compounds with in situ microbial growth and enzyme production. The organic residue generated by the process is converted to methane that can be recovered for fuel. In abstract, this bioprocess technology would help to achieve better quality, speed and pollution control.

    The conventional extraction processes like retting leads to serious problems like methane and sulphide emission, water contamination and other environmental pollutions. Emission of methane and sulphide during the retting process is a major source of environmental pollution as they contribute to greenhouse gases. Owing to the above factors, Biological method is preferred to mechanical and chemical routes for extracting fibres of good quality from the embedding matrix. It is in this context that NIIST devised a clean bioprocess which has the potential to replace the traditional method of retting in which the plant materials are left to decay in humid conditions or in water to free the fibre from matrices.

    Validation level : Real life.; IPR Status : Filed.

  • Clean Bioprocess for white pepper production

    \”White pepper\”, the de-skinned black or fresh pepper is the most valued form of pepper (almost double value of black pepper). Common method for making white pepper is traditional retting, which affects the product quality significantly.

    The innovative clean bioprocess from CSIR-NIIST helps in fast and bulk production of white pepper without losing its spicy principles. The process is designed to cleave the pectin molecular bonding between the skin and oil glands of the pepper kernel by the action of enzymes produced in-situ, This is facilitated in tanks by circulating liquid from a reservoir of a microbial culture grown on degraded pepper skin medium. This bioprocess completes skin removal in 2 days for green and 4 days for black pepper under designed conditions.

    Major advantages for the new process are the following:

    • Achieves better quality white pepper (No foul smell)
    • No loss from process damage
    • Inexpensive and fast
    • Simple operation and scalability
    • Pollution free process with the recovery of energy and bio manure as by-products

  • Swing Technology for Spice Oil, Oleoresin and Encapsulated Flavours from Fresh / Dry SpicesUnlike the conventional technology of the recovery of Oils and Oleoresins from dried spices the new technology offer the following advantages
    • Fresh flavour retained in the end product
    • Higher percentage of flavour / active ingredient recovery
    • Low energy consumption
    • Less possibility of aflatoxin contamination

  • VIRTUAL CASTING – Affordable State-of-the-Art Software for Casting Process Design. Commercial name: FLOW + module in AutoCAST X1FLOW module in AutoCAST X1 is a completely designed software with code developed by the computational modelling and simulation group of CSIR-NIIST based on Virtual Casting Solver Technology of CSIR-NIIST. After testing for industrial case studies and benchmarking with other commercial software like FLOW3D and NovaCAST, with joint collaboration with IITB and 3D Foundry Tech Pvt. Ltd., this technology was transferred to 3D Foundry Tech Pvt. Ltd., (3DFT).

    AutoCAST-X1 with FLOW is one of the very few products entirely designed and developed in India, This product positioned as an easy-to-use, world-class, yet affordable simulation software to Indian foundries and gives them the competitive edge of simulation at an affordable cost (compared to similar products) to deliver defect-free castings right first time and every time. Major benefits of using this product in foundries are reduction of lead time for first good sample casting, very less rejection rates and better customer satisfaction.

  • Fresh Ginger Processing Technology

    CSIR-NIIST have developed and commercialized Fresh Ginger Processing Technology since 2000 for producing value-added products such as ginger oil, dry ginger powder, etc. The institute has set up three processing units in the North East and has transferred this technology to many other industries, CSIR -NIIST provides the know-how, technical assistance insourcing of the machinery, engineering consultancy, training the operating staff, assist in erection & commissioning and troubleshooting. The same technology can be adopted for post-harvest operations of other spices like turmeric, cardamom, etc.
    Considering the climatic conditions of Northeast, cost-effective mechanical drying of various agri crops can also look into for value addition and shelf life enhancement.
    The major advantages are

    • Yield of oil 30 % more than the conventional process.
    • Processing time reduced to 4 hours instead of 18 hours.
    • Reduced energy consumption.
    • Processing cost around 12 % of the total cost of production.
    • Superior quality of flavour.
    • Possibility for byproducts utilization.

  • Organism and Process for Production of Beta Glucosidase (BGL), A Critical Component in Enzyme Cocktail for Biomass Hydrolysis

    CSIR-NIIST had isolated a filamentous fungus from decaying wood in 2005, which was identified as Aspergillus niger and designated isolate no. NII 08121. The fungus produced a BGL which was active at 0.5M glucose and had a glucose inhibition constant (Ki) of 0.2M. The technology developed is a solid-state fermentation process for the production of NII 08121 BGL.

    Beta-Glucosidase is an important component in the enzyme (cellulase) cocktail for hydrolysis of biomass to generate sugars for biofuels and other applications, as this is the rate-limiting enzyme. The availability of enzymes for biomass hydrolysis is important for the future energy security indigenous technologies for enzyme production are warranted. CSIR-NIIST has a solid-state fermentation (SSF) technology for the production of BGL using the fungus Aspergillus niger demonstrated successfully at a semi-pilot scale (up-to 10kg level). The technology would help to produce BGL at a cheaper rate than existing processes and would help in development of efficient biomass hydrolyzing enzyme cocktails for biorefinery applications.
