| Location | AH-CN |
| Geographical representativeness description | Data related to the operation process (e.g., electricity, steam, water, chemicals, raw material consumption, and direct emissions) from the cassava-based ethanol and corn-based ethylene production plants in the Guangxi and Anhui Provinces in China were used [20], [21]. |

| Use advice for data set | Data users should consider the specific context of cassava-based ethanol production in the Anhui province of China when applying this data to their life cycle assessments. Co-product allocation is based on mass, which must be consistently applied across similar assessments. Additionally, due to the reliance on European data for chemical production and background data, adjustments may be required when applying this data set in a different geographical context. The functional unit for allocation is 1.7 tonnes of ethanol production, and this should guide the scaling of inputs and outputs in the LCA model. |
| Technical purpose of product or process | The described cassava-based ethanol production process is designed for the generation of ethanol, which can be subsequently used in the production of ethylene. Ethanol from this process is intended for use in applications that may include biofuel production, pharmaceuticals, beverage industries, or as a precursor chemical for other industrial processes. |
