Use of Sewage Sludge in Cement Industry

The MENA region produces huge quantity of municipal wastewater which represents a serious problem due to its high treatment costs and risk to environment, human health and marine life. The per capita wastewater generation rate in the region is estimated at 80-200 litres per day. Sewage generation across the region is rising by an astonishing rate of 25 percent every year. Municipal wastewater treatment plants in MENA produce large amounts of sludge whose disposal is a cause of major concern. For example, Kuwait has 6 wastewater treatment plants, with combined capacity of treating 12,000m³ of municipal wastewater per day, which produce around … Continue reading

Drilling Waste Management and Cement Industry

During the exploration and production of oil, huge amounts of drilling wastes are produced in the form of mud and cuttings.  As per conservative estimates, around 0.37 kg of drilling wastes is generated for every barrel of oil produced. The American Petroleum Institute (API) has estimated that approximately 1.21 barrels of total drilling wastes are generated for every foot drilled. The Middle East oil and gas industry has made a lot of effort in order to reduce the environmental impact of their activities; modern drilling methods such as horizontal drilling, navigating the drill bits three dimensionally through the earth, contacting … Continue reading
