closed reactor by TNPL for anaerobic digestion of BWW will have many environmental and sustainable development benefits. Replacement of the current wastewater treatment system by a closed anaerobic digester will mitigate large quantities of CH4, a potent GHG, from being emitted into the atmosphere. Controlled environment in which the BWW is treated will reduce strong odours being emitted from the putrescent and degradable components of BWW. By recovering the resulting biogas in the form of CH4 and using it as a renewable in-house fuel for heating equipment, the project activity will contribute to the development of renewable sources as per India's Sustainable Development objectives. The furnace oil which would be replaced by the biogas has a sulphur content of 3.49%. This would result in the emission of sulphur dioxide (SO2) gas which is responsible for acid rain. The use of domestically available biogas as an energy resource helps conserve foreign exchange, apart from creating local rural employment opportunities, by reducing the need to import fossil fuels to meet the country's growing energy requirements. Furnace oil saving will reduce the associated CO2 (GHG) emissions. By registering with UNFCCC for CDM benefit, TNPL became the first paper mill in the country that has registered a CDM project with the UNFCC in waste management. 6.75 MW Small Scale Grid Connected Wind Electricity Generation Project TNPL has gained CDM benefits by generating green energy through renewable wind energy. The project activity involves the installation, operation and maintenance of seven grid connected wind electricity generators (WEG) owned by the project proponent, TNPL. The electricity generated from the seven WEGs will be exported to the Tamil Nadu state electricity board (TNEB) grid. The seven WEGs have been installed in two phases. The first phase involved installation of four NEG Micon 750 kW WEGs and the second phase involved the erection of three Suzlon Energy WEGs of 1.25 MW. All seven WEGs have been installed in the Thirunelveli district, in the state of Tamil Nadu, India. On 30 March 2001, TNPL commenced operations for the first phase of the project with the installation of the four 750 kW WEGs. The second phase of the project has commenced operations in March 2004. All 7 machines supply and sell power to the TNEB grid. By displacing the electricity from fossil fuel based electricity generating systems, average estimated GHG reduction from the project activity is expected to be 14431 tons
