Air pollution: New attempts to tackle Cairo’s black cloud Air pollution: New attempts to tackle Cairo’s black cloud
(about 9 hours later)
Egyptians are bracing themselves for the next season of smog that has come to visit the skies of Cairo and the surrounding cities every year for nearly two decades.Egyptians are bracing themselves for the next season of smog that has come to visit the skies of Cairo and the surrounding cities every year for nearly two decades.
Known in Egypt as the black cloud, the dense smoke first appeared over Nile Delta cities and Cairo in 1997. It spread rapidly and now it accounts for 42% of the country's air pollution, according to the Egyptian Environment Ministry.Known in Egypt as the black cloud, the dense smoke first appeared over Nile Delta cities and Cairo in 1997.

The smog is partially caused by farmers piling up rice straw and burning it, because they lack the means to transfer the rice straw from their fields to recycling centres.The smog is partially caused by farmers piling up rice straw and burning it, because they lack the means to transfer the rice straw from their fields to recycling centres.

In a video produced by the ministry, it said that 1.7 million feddans were planted with rice in six governorates that left 3.4 million tonnes of straw. A feddan is an Egyptian unit of area equivalent to 1.038 acres (0.42 hectares). In at least four regions, the ministry is collecting the waste and recycling it into fertiliser and fodder.In a video produced by the ministry, it said that 1.7 million feddans were planted with rice in six governorates that left 3.4 million tonnes of straw.

"We teach farmers how to deal with the waste to make sure the solutions will be sustainable," Taha says."We teach farmers how to deal with the waste to make sure the solutions will be sustainable," Taha says.
The ministry is now also using satellites to locate the spots where the farmers burn the straw. It has increased its ability to receive complaints and information about violations through a host of platforms including WhatsApp, Facebook, its website and a hotline.The ministry is now also using satellites to locate the spots where the farmers burn the straw.

"I am trying to put an end to the black cloud and to benefit from it at the same time," Yasmeen Moustafa told the BBC. "I believe that the only way to get rid of the massive amounts of rice straw that we produce is to burn it; this is the fastest and the cheapest way. But the problem is in the polluting gases. So I found a way to use these gases to produce biodiesel, fertilisers, vitamin B and hydropower.""I am trying to put an end to the black cloud and to benefit from it at the same time," Yasmeen Moustafa told the BBC.

Yasmeen says her project began as an inquiry into low-cost techniques for water purification. Along the way, she found that the main material used in the biological filtration process was rice straw.Yasmeen says her project began as an inquiry into low-cost techniques for water purification.

"We burn the waste with heat levels reaching 1,200 degrees Celsius, with which we can distillate water," she explains. "The emitted gases are then treated separately.""We burn the waste with heat levels reaching 1,200 degrees Celsius, with which we can distillate water," she explains.

Yasmeen says all the materials needed, like rice straw and algae from stagnant water, are considered natural waste and are cheap. But one limitation to the project's success is the cost of building a plant where the process can take place.Yasmeen says all the materials needed, like rice straw and algae from stagnant water, are considered natural waste and are cheap.

"I am sure there are several new and creative initiatives. If the government works on the execution of one per year, they would save effort and money and would encourage young inventors," she adds."I am sure there are several new and creative initiatives.
