| Use advice for data set | When utilizing the dataset for Life Cycle Assessment (LCA), adopt the functional unit of 1 ton of WDC to quantify inputs such as raw materials, auxiliary materials, energy, transportation, and emissions in accordance with this unit. Apply the cut-off rule as per Zhao et al., 2020, disregarding upstream materials of less than 1% weight of the final product, like fly ash, from the inventory. Integrate these data into the eFootprint platform for a comprehensive analysis of the environmental impact during the brick's life cycle. |
| Technical purpose of product or process | The described industrial process is for the production of sintered bricks, utilizing Water-Based Drilling Cuttings (WDC) as a substitute for natural clay. The sintered bricks produced are suitable for construction purposes, offering an environmentally friendly alternative by recycling industrial waste and reducing the consumption of water and natural clay resources. |

| Technological representativeness | |
| Technology description including background system | WDC（water-based drilling cuttings） were used as a replacement for natural clay to prepare sintered bricks. The water content of the WDC can be reduced from 80% to 20% through press filter pretreatment, which can meet the requirements of external delivery for recycling. The remaining water in the WDC can be used directly to make bricks (240 mm × 115 mm × 53 mm) to reduce the consumption of water resources. The entire production process includes raw material preparation, mixing, pressing, drying and sintering (temperature of 800–1000 °C; time for 1-4 h) |
