Green Initiatives @ JNNCE

JNNCE, located at the foot hills of Western Ghats which is claimed to be one of the top eight bio diversity hot spot of the world is committed to the protection of environment, responsible and efficient use of natural resources under its permissible limits. The Institution is practicing efficient use of natural resources to embrace pollution prevention and committing itself for sustainable development by initiating green policy.

Sewage water treatment is the process of removing contaminants from wastewater, primarily from household sewage. It includes physical, chemical, and biological processes to remove these contaminants and produce environmentally safer treated wastewater (or treated effluent). A by-product of sewage treatment is usually a semi-solid waste or slurry, called sewage sludge, it has to undergo further treatment before being suitable for disposal or land application.

 JNNCE has installed Sewage Treatment Plant(STP) to treat the sewage produced in the campus. The clean water obtained after treating the sewage is utilized to maintain the grass grown in the cricket stadium and lawns inside the campus. The solid sludge obtained is used as manure for gardening. The capacity of the STP is 200KLD.


The institute has a pilot plant of 5KLD phyto-remediation system to treat the sewage. The system is developed based on the research work carried out at Chirantana Green Technology Center, JNNCE. The system uses selected species of plants to absorb salts and degrade the organic matter present in the sewage. Treated water is used for gardening purpose.

Advantages of Phyto-remediation system:

  • Very low construction and maintenance cost, can be handled by unskilled labours.
  • Combination of plant and sand filter is capable of completely removing colour and odour, chemical issues like major trace elements that are considered to be detrimental for healthy growth of plants.
  • The system can be made up of locally available plants and materials and without any chemical application for treatment, so that it is cost effective.
  • Electrical energy requirement for the system is negligible when compared to conventional STP.
  • The approach for reusing of raw Grey water, results in conservation of water resources without any negative impact on environment.

Rain water harvesting is the gathering or accumulating and storing of rain water. Rain water can be used for drinking, irrigation and for ground water recharge purpose. Rain water can be collected from roofs, sloppy ground, roads, etc.., rainwater coming from roof tops are in good quality compared to others.

The rain water from all the buildings in the campus is collected in a huge reservoir constructed which has a capacity of 10 million liters. The annual collection of water is around 6 million liters. The water collected in the reservoir is treated using indigenously developed water treatment system and supplied for in house consumption for other than drinking & cooking purposes.

JNNCE is committed to its green policy.  Currently the annual electricity consumption of the campus is around 1 million units and the corresponding CO2 emission is about 1000 tons per year. In this direction, we are installing 400 kW Solar Roof Top system is being installed and would be commissioned November 2019. This system would meet about 80% of the total energy requirement of the campus and prevents 800 tons of carbon dioxide being added to atmosphere annually.

Solid Waste Management System of one ton per day capacity has been established at JNNCE in the year 2017.  The system consists of Shredder Machine and Chopper Machine. The biodegradable solid waste generated in the college campus and the hostel is collected and dumped in one place, Further it is powdered and added with compost culture to increase rate of decay of the waste. The manure, thus obtained is used internally for the garden and the excess if any is sold to farmers at a marginal price.

The institute has a bio diesel production unit funded by Karnataka State Bio Energy Development Board. The center produces bio diesel using pongamia seeds and used cooking oil. The bio diesel is blended with diesel and can used in a few college buses. The excess quantity of bio diesel and its byproducts i.e., Pongamia cake, glycerin soaps are sold in the local market. A study on performance of biomass gasifier for power generation using wood and wood agro-residue mixtures was carried out. .
