Cement, Energy & Environment Jan-Mar 2002

Lafarge's commitment will be achieved by intensifying a series of actions that the company has been undertaking for more than a decade. The main levers that Lafarge will use to reduce its emissions are: improving energy efficiency; using waste fuels and incorporating cementitious additions, such as steel slag and fly ash from coal-fired power stations. WWF has welcomed Lafarge's intention to increase energy efficiency and utilise less carbon intensive cement production to reduce its C0 2 emissions . Courtesy : World Cement Dec. 2001, P5.

Environmentalists are concerned about possible air pollution in the area on account of the NTPC super thermal power station. This has led to organization of a two-day national brain storming session of waste recycling experts by the Ministry of Power and NTPC to explore viable use of fly ash. NTPC is particularly concerned that its 3000 MW power plant at Kaniha will use about 14 000 truck loads of coal per day, thus posing it a big challenge to dispose off 5000 truckloads of ash everyday. The plant will be completed between 2004/06. In this 50 backdrop, the proposed joint venture wth IDCOL may well be a way out. Courtesy : TERI Newswire, 1-15 Dec 2001, P30-31.

RECYCLING TYRES USED TO REDUCE TRAFFIC NOISE Old plastic bumpers and tyres from scrapped cars are being used in a noise-control project launche~ by researchers in collaborationwith partners in the Czech Republic and Japan. The polymer bumpers are shredded into a small gritty substance that is bonded into a matrix of porous material and used to deaden traffic noise, to soundproof buildings and improve acoustic control. The tyres are granulated and combined with polyurethane for a variety of uses such as noise reduction in vehicles and road barriers. Dr. ·Horoshenkov is co llaboratin g with scientists at the Techrlical University in Bmo in the Czech Republic and the Kyshu Institute of Design in Japan which specialise in the manufacture of acoustic materials. The new product is expected to be marked in 2001. Courtesy:· Productivity News; ]ul-Aug, 2001, P 20.
