Metal and other scraps are given to agents for further processing.
Separate Dustbins for recyclable and non-recyclable wastes are available in common places.
Used batteries and electronics wastes are disposed of through outside agencies.
Various awareness programs like tree plantation, energy conservation etc are regularly organized.
Environmental Science is also a mandated course for all the students.

Sources of energy and energy conservation

An alternative Energy source offers the opportunities to engage in initiatives for contributing to environmental protection.

The institute is a high tension(HT) consumer with an average consumption of 40,000 units of electricity every month and a contract demand of 200kVA. The electricity bills stood high while usage of electricity couldn’t be compromised on. The concept of a non-conventional energy source owned and operated by the institute seemed a feasible solution.

The alternative energy sources of Institute is made for proper implementation and efficient utilization of renewable energy sources in a systematic way so as to minimize its impact on the environment.

Energy conservation is classified in to four broad categories. They are:

Solar Energy
Biogas Plant
Sensor Based Energy Conservation
Use of LED bulbs / Power Efficient Equipment

The institute has taken following measures for conserving the energy.

Solar Energy

The large magnitude of solar energy available makes it a highly appealing source of electricity. Various efforts have been taken by the institute to utilize the solar energy in an effective way. A rooftop solar power system, or rooftop Photovoltaic (PV) has its electricity-generating solar panels mounted on the rooftop of institute buildings.

The project was initially conceived as a 200kW solar power plant to meet all the needs of the institute but received approval for a 160kW power plant from TSSPDCL (Telangana State Southern Power Distribution Corporation Limited) on technical grounds. The installation a 160kW solar panel reduced the contract demand by about 80kVA. With the solar power generating station expected to generate 2 lakh units per annum, reduction in contract demand and savings in power consumption would mean an annual saving of Rs. 18 lakhs for the institute.

Five hundred and ten panels of 315W have been installed. Five on-grid inverters of 33kW installed as a part of the plant help in sending electricity generated directly to the grid instead of storing it in batteries. On working days, the solar power plant can partly take care of the electricity needs of the institute, with the rest being supplied by the electricity board. During holidays, the plant exports the power to the grid.

Solar water heating system has been installed at the top floor of the Boys and Girls Hostel and the generated hot water is supplied for the utilization in hostel.

The solar energy is collected during day hours is transformed into electrical energy and stored in the battery for lighting system during night hours.

The above three solar energy technologies are used in the institution, and for promoting the renewable energy usage the various awareness programmes are organized among faculty and student community.

Highlights

Rooftop solar power can meet up to 35% of electricity requirements.
Diesel for power generation, decrease up to 15% of diesel bills.
Cost-effective – Rooftop solar power has a levelised cost of Rs. 4.5-5/kWh (or less), considerably lower than diesel power cost at Rs. 18/kWh (or more).
Additionally, energy cost is fixed for the next 25 years, unlike diesel / power which keeps increasing.
Students gain practical, hands on knowledge of solar plants.

Biogas Plant

Biogas plant is constructed to reduce the use of cylinder consumption. The feed to the plant are the contents of the organic waste from the leftover and expired food from hostels. Biogas plant has been installed backside of the canteen and dining hall for waste management with the capacity of 02 cubic meter and also to produce the gas which is used as cooking fuel.

Sensor Based Energy Conservation

Automatic Water level control sensor is used in overhead water tanks. In the campus, ground water is pumped up to overhead tanks using water pumps which are controlled by electric motors. Automatic water level controller for overhead tanks that switches on/off the pump motor when water in the tank goes below/above the minimum / maximum level. Lighting in toilets and corridors are fitted with automatic sensors, during its function, when a person enters, automatically lights gets switched ON and gets switched OFF automatically.

Use of LED bulbs / Power Efficient Equipment

LED bulbs are filled with required energy and can use up to 90% less power when compared to incandescent / CFL light bulbs. They are highly efficient. LED bulbs are used in various places in the institute for achieving proper lightings. The CFL fittings with higher rating wattage are replaced with LED fittings with lower wattage with the same luminous level in street lights and other possible areas of the campus. Energy star certified (BEE 3-5 star) products are installed in smart display units (LED televisions) in class rooms, air conditioners, microwave, refrigerators, ceiling fans and others in the campus.
