Problem or opportunity?

摘要

As the operator of Castle Peak Power Station, one of the largest coal-fired power stations in the world, CLP Power currently produces nearly 350,000t of coal ash every year. The peak production of ash at Castle Peak occurred in 1992, when it reached close to one million t. Instead of disposing of this ash as a waste product, CLP Power has been promoting its use as a construction material since the 1980s. After a lengthy process of gaining acceptance by the construction industry, coal ash is now used successfully in a variety of applications. This can only be achieved through a concerted marketing effort supported by extensive research, and by investing in facilities required to turn coal ash into a product of considerable commercial value.
