Milestone for recycling

In October, 2000, Castle Cement workers reached a recycling milestone. At Llay, near Wrexham, the company has processed one million tonnes of shale, a low-grade coal left over from the former Llay Main colliery.

The processed waste is used as a raw material along with sand and limestone, to make cement at Castle’s Padeswood works. If the company is given permission to build a new kiln there, production capacity will be increased by more than 50%.

What the government says:

“Where waste is produced we must put it to good use, through re-use, recycling, composting and recovering energy.” Waste Strategy 2000 for England and Wales, DETR/National Assembly.

“In this case (cement manufacture), the benefits to the environment go hand-in-hand with a helpful contribution ... to improving the international competitiveness of the cement industry.”
