Cement Energy and Environment

ENERGY EFFICIENCY & CONSERVATION Energy Conservation NUH CEMENT AND BATICIM TO START ELECTRIC POWER GENERATION FROM WASTE HEAT Nuh Cement Industry Inc. is continuing the studies aimed for setting up generating plant from waste heat emerging from the plant in cooperation with Chinese company Sinoma within the scope of an agreement. It is expected that the plant established for reducing power generation costs of the company, would be completed in two years and about 25 per cent of power generation costs would be reduced with this new plant. Accordingly, Bati~m. Bati Anadolu <;imento Sanayii Inc. will also generate power from waste heat within the scope of an agreement signed with Sinoma. This project, having ongoing engineering and production oriented operations, is scheduled to be commissioned in 2012. Estimating that such facility would produce for 7.700 Hours/Year with a capacity of 8.9 MW, it is aimed at generating approximately 68,500,000kWh electricity power per year. With the project of which such amount covering about 30 per cent of the annual electricity power consumption would be on the "environment", it is aimed at ensuring a reduction in carbon dioxide (C0 2 ) em1ss1on of 35,000 tonnes equivalent to plantation of 31 ,000 trees per year owing to the electricity power to be generated from waste heat.

INTELLIGENT USE OF LIGHTING CAN HELP SAVE ENERGY AND MONEY In this modern day and age, we are completely dependent on appliances and gadgets to make our lives more comfortable. But most of these appliances run on energy (electricity) and their constant use, coupled with the rapid increase in demand, is aggravating the already grave situation of scarce energy resources. At an individual level, this also causes the problem of huge electricity bills for the consumers. Some people debate that electrical appliances, especially light:>, should remain switched off for as long as possible. But no matter how hard you try, this is neither possible nor feasible. Light affects our health, safety, morale, comfort and productivity; and the quantity and quality of light around us determine now well we see, work and play. In your home, you can save energy without having to compromise on the light quantity and quality by taking some simple yet important decisions. To start with, you can carefully choose the lighting fixtures to be installed in your home. These should be chosen keeping in mind their energy efficiency, size of the space and the availability of alternate light source such as natural light. Newer technologies such as CFLs, LEOs and the new sleek T5 tube lights are up to 10 times more energy efficient than the traditional incandescent bulbs and offer great savings. You should ensure that the products installed are certified and labelled lighting fixtures. If chosen correctly, these could considerably bring down the running, maintenance and replacement costs. Hence, you should look at lights and lamps as investments and choose them wisely rather than picking them on the shelf. For instance, if you install six 14W CFLs in your house instead of six 60W GLS lamps that stay on for 8 hours each day on an average, you will get the same light output while consuming only 0.6 units of electricity as against consuming 3 units of electricity in case of GLS lamps. This resul ts in energy savings of 2.4 units per day or 876 units per year. This translates into annual energy savings of over INR 5,000 and huge net savings after considering the initial cost of the lamps replaced too. Plus, you could save even more by replacing GLS lamps/halogens of even higher wattage with CFLs or T5 tube lights. Leading brands like Philips are also partnering with state governments as part of the Bachat Lamp Yojana programme by the Bureau of Energy Efficiency for replacement of GLS lamps with CFLs. Philips has also distributed CFLs to house holds in Kerala that helped the state achieve peak load reducti on and reduced C0 2 emissions. As part of the programme, Philips helped the Kerala government by providing 15 million CFL lamps for 7.5 million households in Kerala. This was a big step for both the government and the company as it targeted a peak load reduction of-300 MW, and reduction in C0 2 emissions by 0.5 mi llion tonnes per annum. Philips also supplied 2.6 million CFL's to replace incandescent lamps in the Indian Railways Housing colon ies across the country. The switch is aimed to 19
