The slag resource comprehensive utilization project adopts the "pre-treatment + brick-making" process, so that the waste incineration slag can realize resource recycling. The slag is pre-treated through various processes to stabilize the slag composition to meet the requirements of the subsequent brick making process. The comprehensive utilization of domestic waste incineration power generation slag not only saves landfills, but also provides green and environmentally friendly building materials for urban construction: permeable bricks, grass-planting bricks, various types of road bricks, and recycled concrete environmental protection bricks. Brick clay is used to implement the national policy of “saving clay and protecting cultivated land”.
