Climate Change Protection The Company is fully aware of the climate change problem and therefore has set a target to reduce carbon dioxide emission and to manage the crucial factors in the bid to reduce carbon dioxide emission, such as, the determination to use more alternative raw materials and fuels, by using discarded materials and industrial wastes as alternative raw materials and fuels; the determination to increase the efficiency in energy consumption, as well as to develop products that are more friendly to the environment by reducing the clinker factor in the cement products while improving the workability characteristics.
Atmospheric Emission Reduction The Company pays close attention to pollution control in every step of the production process, especially in the production of clinker where we have installed the Electrostatic Precipitator (ESP) covering for all main kiln stacks to collect dust and have followed up with the continuous emission monitoring system (CEMs). These include particulate matters, sulfur dioxide, and oxides of nitrogen. The control and monitoring system operates 24 hours a day by keeping the concentration of total suspended particulate matter (TSP) below 50 milligrams per cubic meter (mg/m3), the control of the concentration of sulfur dioxide emission to below 30 parts per million (ppm), and the control of the concentration of oxides of nitrogen to below 500 parts per million (ppm) which are the parameters stipulated by law. This is to ensure that every ton of clinkers that we produce has gone through the best practice in the vigilance and monitoring of pollution emission.
Utilization of Alternative Raw Materials and Fuels The Company has the policy to try to utilize alternative raw materials and fuels, such as industrial waste, for use in place of the traditional fuels and raw materials in the cement production process. This is done by using alternative fuels for co-processing in cement kilns. This process helps to reduce the amount of carbon dioxide emission that is the root cause of global warming and pollution.
Water Management The Company places great importance on the conservation of water resources through the determination to operate the business with the society sustainably in the co-use of water resources with the community for the utmost benefit by resolving to develop the water management system and increase the water usage efficiency per unit of cement production through the 3Rs (Reduce, Reuse, Recycle) concept, followed by the risk management in the case of water resource scarcity. Meanwhile, the Company has evaluated the direct and indirect usage of water throughout the water footprint to systematically analyze the steps with significant water usage and to find ways to further reduce the water used in the production processes in every way possible, especially the use of surface water and to create awareness among the employees within the organization to help support the water conservation movement through productive use.
Waste Management The Company is determined to adhere to the waste management policy to create the highest value from the available resources as well as to reduce the amount of waste as much as possible through the 3Rs concepts which are Reduce, Reuse and Recycle. We can leverage the waste arising from the cement production process by processing into alternative fuels reused in cement kilns, which is the adherence to the principle of “Zero Waste to Landfill”. The Company is fully aware that the problem of waste management is an issue that everyone in the Company has to buy-in. Therefore, we have promoted the participation of the employees as well as to educate them in the process of waste management – from collection to separation and to recycle, through major projects, such as the “Green Heart Bank”.
Biodiversity Management The rehabilitation of the forest following the quarry activities through the rejuvenation of the ecosystem and increase the biodiversity for both flora and fauna, returning them to the condition closest to pre - quarry operation phase. This is another crucial mission of Siam City Cement that has been carried out sustainably and continuously upgraded. Among the more important activities are planting trees in depleted mine area (rehabilitation), the creation of the nursery for seedlings and saplings of indigenous plants, and later transplanting them in rehabilitation plots. Also important is the commissioning of outside experts to study and analyze the biodiversity in the area and consult in the drafting of the Biodiversity Management Plan, as well as to promote understanding and acceptance of the community by arranging open-house activities for community members to visit. A project has also been created to give saplings for the youth in the community to look after, thus bringing them closer to nature.
