Fourteen parameters determine the quality of coal. Some of them are directly related to the effect of coal on the environment. Based on these parameters, the Israeli government has formulated strict standards for import and use of coal designated for the electricity production process. We meticulously ensure that the coal purchased meets the quality standards set by the government, thus reducing air pollution in Israel.
Prior to each coal purchase, we utilize the services of leading laboratories in Israel and worldwide in order to perform sample checks for coal, providing us with information on its quality.
Using Coal Ash
The National Coal Ash Board was established for the purpose of protecting the environment, and its objective is to promote beneficial usage of coal ash – the mineral residue remaining from the coal burning process in power stations. Using various processes, Coal ash is transformed from contaminative waste into a useful resource holding economic, technical quality and environmental benefits. Coal ash is an excellent alternative for various natural raw materials, and enables avoiding the production of these materials, which entails eruptions of contaminating substances into the atmosphere, including greenhouse gas and poisonous gases.
Coal ash is mainly used in Israel as a raw material in the construction and infrastructure areas. In construction, it is used as an additive to cement and concrete, thus reducing the discharge of carbon dioxide during the manufacture of clinker (a sub-component of cement). Due to the lightweight, airy structure of the coal ash, it also serves as a raw material for bricks, and improves their insulation capability. Coal ash thus contributes to energy savings and to the environment.
Coal ash serves as a structural filling for road paving, as a component of asphalt, and is also utilized as a bed for growing plants, for improving inferior soil for agriculture, and as a stabilizer for sewage sludge which is used as fertilizer.
