Use advice for data set | When utilizing this LCA dataset, users should adhere to the cut-off rule as defined by the functional unit of 1 ton of WDC, excluding low-value materials from upstream processes accounting for less than 1% of the final product's weight, such as fly ash, from the inventory. This guideline is essential for maintaining consistency with the dataset and ensuring the accuracy of the life cycle assessment. Users should apply this data within the context of the specific environmental goals of the project, and keep in mind the technological applicability described, ensuring appropriate methodological adherence for raw material preparation, mixing, pressing, drying, and sintering stages. |
Technical purpose of product or process | The described industrial process for brick production involves using water-based drilling cuttings (WDC) as a substitute for natural clay in the manufacturing of sintered bricks. Sintered bricks produced using this process are intended for use in construction activities, suitable for common masonry applications such as the construction of walls, buildings, and other structures. The process is aimed at utilizing industrial waste (WDC) as a primary raw material, to promote recycling and reduce the environmental impact associated with the extraction of natural clay. |

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) |
