Use advice for data set When leveraging this dataset for Life Cycle Assessment (LCA), it is critical to consider the substitution of water-based drilling cuttings for natural clay, as well as the efficiency in water usage. The dataset is specific to Chuangqi Environmental Protection Building Materials Co., Ltd., and should be adapted accordingly if applied elsewhere. The cut-off rule applies, permitting the exclusion of inputs such as fly ash that represent less than 1% of the end-product's weight. All inventory parameters should center around the functional unit of 1 ton WDC.
Technical purpose of product or process This industrial process is applied in the brick production sector, specifically for the manufacturing of sintered bricks utilizing water-based drilling cuttings (WDC) as an alternative raw material to natural clay. The process involves the preparation, mixing, pressing, drying, and sintering of bricks, integrating waste material recycling and water resource conservation strategies.

Functional Unit 1t WDC were chosen as the functional unit
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)
