Thousands of tonnes of camel dung are being used to fuel cement production in the northern United Arab Emirates, cutting emissions and keeping animal waste out of landfill, according to a report from Reuters.
Under a government-run scheme, farmers in the emirate of Ras al-Khaimah drop off camel excrement at collection stations. It is then blended with coal to power the boiler at a large cement factory.
“People started to laugh, believe me,” said the general manager of Gulf Cement Co., Mohamed Ahmed Ali Ebrahim, describing the moment the waste management agency proposed the idea. But after running tests, the company found two tonnes of camel waste could replace one tonne of coal.
“We heard from our grandfathers that they used cow dung for heating. But nobody had thought about the camel waste itself,” said Ebrahim, whose factory now uses 50 tonnes of camel dung a day.
Cow dung has been tapped as a resource to generate energy from the United States, to Zimbabwe to China. Camel dung is a rarer fuel but one well suited to Ras al-Khaimah, one of the seven emirates that make up the UAE, home to around 9,000 camels used in milk production, racing and beauty contests.
A blend of one part dung to nine parts coal burns steadily – essential for cement ovens. The main aim of the project is to prevent camel waste from ending up in the dump, with the government seeking to divert 75% of all waste from landfill by 2021.
