Energy Efficiency in Saudi Cement Industry

Saudi Arabia is the largest construction market in the Middle East, with large development projects under way and many more in the planning stage. The cement industry in the country is evolving rapidly and is expected to reach annual clinker production of 70 million tonnes in 2013 from current figure of 60 million tonnes per year. The cement industry is one of the highest energy-intensive industries in the world, with fuel and energy costs typically representing 30-40% of total production costs. On an average, the specific electrical energy consumption typically ranges between 90 and 130 kWh per tonne of cement. … Continue reading

Agricultural Scenario in MENA

Agriculture plays an important role in the economies of most of the countries in the Middle East and North Africa.  The contribution of the agricultural sector to the overall economy varies significantly among countries in the region, ranging from about 3.2 percent in Saudi Arabia to 13.4 percent in Egypt.  Large scale irrigation is expanding, enabling intensive production of high value cash and export crops, including fruits, vegetables, cereals, and sugar. Egypt is the 14th biggest rice producer in the world and the 8th biggest cotton producer in the world. Egypt produced about 5.67 million tons of rice and 635,000 tons of … Continue reading

Sustainability in MENA Cement Industry

The population in the MENA countries has doubled during the last 30 years (from ca. 110m in 1980 to almost 220m in 2010). As per conservative estimates, the rate of urbanisation in the MENA countries will exceed 70% five years from today (average for all developing countries: 54%). The proceeding urbanisation and the population increase involve several problems and challenges for the national governments and also for the cement industry. The cement production of countries in the MENA region has almost tripled during the last 15 years up to approximately 500m tons  Since the start of national revolts and demonstrations in … Continue reading

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

Energy Sector in Arab Countries

The Arab energy sector has played and will continue to play an important role in the regional as well as global economy. In addition to satisfying energy needs for economic and social development, it is the source of oil and gas export revenues contributing to economic development. The Arab oil and gas sector represents the largest economic sector in the region. Increase of oil revenues were the main drivers for economic development in most of the Arab oil producing countries. Due to the remarkable recent increases of the oil prices and the escalated levels of oil production in some Arab … 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
