details of various R&D activities being carried out by NLC are given
pond reclamation and possibilities of utilization of industrial waste for
joint project between NLC and Annamalai University for developing green
in the abandoned ash pond area using advanced biological reclamation
objective of the project is to convert the wasteland into productive land by
green cover with suitable crops/soil ameliorants.
study indicates that the heavy metal leaching is negligible in the abandoned
pond. In the second phase field trial Eucalyptus, Casurina, Coconut &
planted in ash pond-TPS-I and biometric observations are being recorded.
and fourth phase field trial were completed with crops like sorghum,
black gram, Bhendi, cluster bean, and with flower varieties respectively
amendments. Ash and water samples collected are being analysed for heavy /
elements. The mixing equipment and power tiller procured were installed and
Purchase action for the procurement of the other equipment approved for
project in progress.
conversion of lignite to humic acid
project involves joint research work between CARD/NLC and Central Fuel
Institute, Dhanbad under assistance from Department of Coal. The main
of this project is microbial extraction of humic acid from lignite.
Sample collection and isolation of micro-organisms were completed. Project
assistant posted and laboratory scale experiment are in progress using
Humic acid developed from bio-technical method was tested at CFRI and
are encouraging. The equipment earmarked for the project such as
and electrophresis system purchased by CFRI are commissioned at
Further studies are being carried out using the above equipment.
of cost effective High Performance highways using fly ash
work is jointly carried out between Civil/CTO & CARD/NLC and Anna
Chennai. The main objective of this project is to explore the possibility of
bulk ash in highways road. Samples were collected and analysed. The
design trials are in progress at Anna University. After completion of mix
of experimental roads will be taken up. The equipment purchase is under
studies on application of humic acid and crop response in various
is a joint project between CARD/NLC and Tamil Nadu Agricultrual
(TNAU). Humic acid is the plant growth stimulant extracted from lignite by
method at pilot plant at CARD. Project commenced from July’2000. First
of field trials commenced at different agro-climatic conditions viz,
Coimbatore, Bhavanisagar, Pollachi, Alandurai and crops like groundnut,
paddy, green gram and black gram were tested with varying levels of humic
Application of humic acid increased the yield by 40% when compared to crops
samples harvested at Vriddhachalam. Field experiments were completed with
crop at Aduthurai, Cauvery Delta and significant yield increase was recorded
of humic Acid up to 30 Kgt/ha.
of lignite and bioremediation of its sulphur rich wastes for
of environment friendly value added products
is a joint project between CARD/NLC and Indian Institute of technology,
Delhi. The main objective is to develop a technology to solubilise lignite
microbes, production of methane and microbiologically desulphurize bottom
and marcasite so as to recover sulphur and microbiologically desulphurize
samples collected and sent to IIT, Delhi for further studies. Glass column
leaching study using the stains separated from mines is in progress.
equipment approved for the project is in progress.
of marcasite from pulverised lignite using fluidized bed
aim of the project is to study the effect of parameters namely, flow rate of
material characteristics and composition of lignite and dense particles on
of higher density material (eg. Marcasite) from lower density material (eg.
in a laboratory fluidized bed. The project proposal has been resubmitted to
Sub-Committee for consideration and approval.
of process for the production of Activated Carbon from Neyveli
project aims to develop a process for the conversion of Neyveli lignite tos
activated carbon involving reactive solids. It is proposed to optimize the
parameters for the conversion of Neyveli lignite to activated carbon to
engineering data to design and scale up to commercial plant levels and to
and evaluate the product as per National and International Standards. The
aims to confirm techno-economic feasibility for commercial scale
