twenty eight districts in Tamil Nadu under the Farm Forestry scheme and under the Captive Plantation Scheme. In all, TNPL has established pulpwood plantations in about 40291 acres (as on 31 March 2009). Clonal Propagation and Research Centre (CPRC) To cater to the need for a huge amount of planting material to the tune of 15 million plants to cover every year, TNPL established a state-of-the-art clonal propagation and research centre (CPRC) to achieve self-sufficiency in planting material and production of quality clonal/ seedling plants with a capacity of 15 million plants per annum. The clonal production centre was started with a mini clonal hedge garden of 4000 sq.m, a mist chamber of 8000 sq.m, 5300 sq.m of hardening chamber and 20000 sq.m of open nursery with updated technological innovations as per international standards. The clonal production center was established at an outlay of about 50 million. This is considered to be a milestone in the plantation activities and assures quality planting material availability throughout the year The above plantation schemes are being implemented throughout Tamil Nadu through 10 regional offices in Karur, Manaparai, Tirunelveli, Karaikudi, Pudukottai, Namakkal, Trichy, Tanjore, Jayangondam and Panruti providing advice and technical assistance to tree growers. Forestry research and development TNPL has partnered with the NAIP-ICAR sponsored project titled "A value chain on industrial Agro-forestry in Tamil Nadu" for Promotion of tree husbandry with improved short rotation clones/genotypes through contract farming. Forest College & Research Institute (FC & RI), Tamil Nadu Agricultural University, Mettupalayam is the Consortium Leader of this project. This project is being implemented for raising of cluster plantation in 10 Taluks covering 5 Districts in Tamil Nadu. Solid waste management Fly ash generated at the power boilers is being sold to the cement plants Effluent sludge is being sold to the Board manufacturing units Lime sludge generated is being recycled in the Lime Kiln TNPL has obtained the prestigious ISO 14001 Certification from RMTUV, Germany for "Successfully establishing and applying environmental management system for development, manufacture and supply of paper". This certification duly acknowledges TNPL's commitment for environment protection and sustained efforts to minimise the overall environmental impact. TNPL has commissioned the Bio-methanation plant, which generates around 23000 m3 of biogas (methane) per day, to be used as fuel in the lime-kiln in replacement of furnace oil. The biogas e replaces around 10–12 KL of furnace oil per day in the lime-kiln.
