Qatar: Al Khalij Cement Company (AKCC) has signed a memorandum of understanding with Qatar’s Public Works Authority (Ashghal) to recycle 100% of the sludge generated by the country’s wastewater treatment plants into alternative fuel for cement production. The five-year agreement aims to convert between 744,000t and 1.29Mt of sludge into alternative fuel. According to Mohammed bin Abdulaziz Al Meer, president of Ashghal, treated water will be reused for irrigation and cooling, while solid byproducts like sludge will be used as fuel catalysts and inputs in cement manufacturing. The use of the sludge-derived fuel will reportedly reduce natural gas consumption and lower greenhouse gas emissions. AKCC said that the use of alternative fuels under the agreement will reduce CO₂ emissions by around 40,000t.
