The correct answer is Indian Oil Corporation Limited. The Tirumala Tirupati Devasthanams (TTD) will establish a compressed biogas (CBG) plant in Tirumala in collaboration with Indian Oil Corporation Ltd (IOCL) on a 50:50 cost-sharing basis. Since March 27, 2017, the temple body had contemplated a municipal wet waste treatment plant at the hill town with Windrow technology, which would produce compost or manure and minimize the adverse impact on the environment. The compost is being produced by O&M. Officials came up with the idea of bio-methanation or production of biogas as one of the best alternatives for disposal of wet waste, as it produces gas that can be used for cooking, heating, and production of electricity. As per estimates, the total requirement of LPG at Tirumala is an average of 3. 335 MT per day. The proposed solar steam cooking system taken up by NREDCAP will reduce 1/3rd of LPG consumption by 1. 1 MT per day. The proposed CBG plant will produce approximately 1. 752 MT of biogas daily. Thus, dependency on LPG will be reduced to a great extent, resulting in net savings of around ?2 crores per year for the TTD. Additional Information TTD is headquartered in Tirupati and employs about 16,000 people. Formed in 1932 and Chairman is Y. V. Subba Reddy. The Andhra Pradesh Charitable and Hindu Religious Institution and Endowments Act (1969), sections 85 to 91, expanded the provisions of TTD. The number of trustees was expanded from five to eleven with compulsory representation from certain communities. The A. P. Charitable & Hindu Religious Institutions & Endowments Act (1987) superseded the 1979 act. The Board of Trustees' membership was expanded from a maximum of eleven to fifteen and the hereditary rights of temple priests and their right to garner a share of the hundi proceeds were abolished. the AP government amended the act in 2006, to discontinue two controversial clauses.
