JNTU Plans To Produce Biogas From Kitchen Waste 

Hyderabad, Feb 28 (Maxim News): JNTU is focusing more on the use of non-conventional energy sources. While the establishment of a solar energy plant at Sultanpur JNTU College is already saving electricity charges significantly, the authorities are soon making plans to produce biogas from kitchen waste from hostels on the Hyderabad campus.

Currently, there are Gautami, Kinnera, Majira, and Kamala Nehru hostels on the university campus, and a minimum of 750 to a maximum of 900 quintals of kitchen waste is being sent to the municipality dumping yards from these hostels every day. However, senior officials believe that producing biogas from that waste will not only save on gas costs but will also earn green energy credits for the university. Since green energy credits are given priority in the application submitted for NAAC accreditation and NBA accreditation for the engineering college of the university, this will help in obtaining the respective accreditations. 

Green Energy Promotion

As part of promoting green energy, the Central and State governments are providing a subsidy of 50 percent of the cost of setting up biogas plants. However, it seems that the state government is considering proposals to provide this subsidy, which is currently provided only to large plants, to small and medium-sized plants as well.

Srinivas, a JNTU alumnus who has done research on the subject of biogas production, said that in addition to producing biogas from kitchen waste and food waste, more income can be generated if the final waste is also converted into compost. Keeping in mind the long-term benefits, he said that if an anaerobic digestion (biogas plant) with a capacity of 1,000 kg is set up on the university campus, JNTU can be converted into a zero-waste campus. 

Senior officials have estimated that generating biogas from kitchen waste in university hostels will save Rs. 4.32 lakhs annually. A plant with a capacity of 1,000 kg of waste can produce 52 kg of gas per day. On average, the cost of using 3 LPG gas cylinders per day can be reduced by up to Rs. 3,000 (at Rs 1,000 per cylinder).  While saving Rs. 36,000 per month, it is estimated that the cost can be reduced by Rs. 4.32 lakhs per year and by about Rs. 22 lakhs over five years. Moreover, the professors believe that setting up a biogas plant (anaerobic digestion) in the university will be very useful for research students.
