The sustainable supply chain proposed in this paper aims to study the operational process of a coal-fired power plant, to see how a humble fossil transforms into energy, and how electricity is created step by step inside the plant. In order to fully understand the eco-design of this supply chain network, we have studied the utilization of electrostatic precipitators in a coal power plant, and their ability to remove ash, dust and smoke from the flue gas so it does not pass into the atmosphere, thus comply with environmental regulations.
