Car tyres drive energy for UAE cement unit

Car tyres drive energy for UAE cement unit

The National Cement Company has achieved a regional first by using old car tyres to generate energy for cement production.

‘We can use all heavy plastics, tyres, hydraulic hoses, water pipes,’ Helal said. ‘It generates energy similar to that produced by oil.’

At this stage, however, the tyres only supplement oil, comprising 10 per cent of the fuel.

Helal explained large quantities of the raw material generated excessive gases which upset the chemical balance. But as technology improves he expects more tyres could be used.

Most harmful emissions are eliminated during the process, keeping the factory’s emission levels well below a third of the allowable limit.

‘Using the tyres does not harm the environment,’ he said.

The National Cement Co. already has a greater supply of tyres than it requires. ‘Originally we were paying for the tyres but now we don’t because we have too many people coming,’ Helal said.

The company had been aware of the technology for about five years when the first factories began implementing the technology in Europe. It was only when the company had a higher capacity, about one year ago, that the process was introduced.

‘This is the first factory in the UAE and probably the Middle East using tyres to generate energy,’ he said.

The factory uses between 1,800 to 2,200 tyres per day or between one and one and a half tonnes per hour.

In a related development, Bee’ah, the environmental solutions company in Sharjah, has plans to develop tyre-recycling facilities this year, but the tyres will not be used to generate energy.

Bee’ah Managing Director Samer Kamal said the UAE had one of the highest numbers of cars per capita in the world and there were an estimated 50 million tyres lying in landfills in the country.
