Qatar: The Ministry of Environment and Climate Change has organised a symposium to launch a new ‘green’ cement made from sewage waste, with aims to support environmental sustainability and the circular economy in line with the Qatar National Vision 2030. The symposium highlighted the role of scientific research in transforming sewage into green cement. The cement is produced by treating sludge, resulting from solid sewage waste by burning, grinding and mixing it with catalysts, then is practically applied in the manufacture of building blocks and foam concrete. The amount of accumulated sewage waste is estimated at about 40,000t/yr, which can be used to produce 40 million bricks or 150,000m3/yr of foam concrete.
