SURELY it is a good thing that Castle Cement is using chipped tyres as fuel (Letters, June 8)?

The tyres are completely incinerated, which saves the countryside from 1,000 lorry loads of landfill per year, and it means the company can cut down on using the UK's limited reserves of coal.

And the suggestion that animal carcasses are burned is not true.

Sterilised agricultural waste -- bone and meat -- is ground down to powder. Burning it produces fewer emissions than burning coal, and again saves using landfill. If we think industry should not use these alternative fuels, it's only fair that we should live in houses without cement, drive cars without tyres, and we should only be allowed to eat a steak if we are willing to eat all the rest of the animal too!
