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

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

Environmental Best Practices for MENA Cement Industry

Cement production in MENA region has almost tripled during the last 15 years, mainly on account of high population growth rate, rapid urbanization, increasing industrialization and large-scale infrastructural development. The growth of cement industry in MENA is marked by factors that are directly connected with sustainability, energy efficiency and raw material supply. Although the factors differ from country to country and cannot be generalized, there are major concerns regarding shortage of raw materials, GHG emissions, dependence on fossil fuels and lack of investment in technological innovations. For the MENA cement sector, key points for an environment-friendly industry are use of … 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

Primer on Wood Wool Cement Board

Wood Wool Cement Board (WWCB) is a versatile building material made from wood wool and cement where each fiber is coated with a thin film of Ordinary Portland Cement (OPC) that, when cured, partly petrifies the wood. In that way the fiber will last indefinitely as long as the cement film is not damaged. Environmentally speaking, cement has a negative CO2 signature and therefore both the wood and cement, when decomposed, are harmless to nature and as a result all homogeneous WWCB products have green labels in Europe. It combines the advantages of both wood and concrete together: as light … Continue reading
