Through experiments, the relevant data of the sludge pyrolysis treatment process under different working conditions are collected and distributed, and the input and output of materials and energy in each process are quantified, and the environmental pollutant emissions are quantified. When using this data set for Life Cycle Assessment, users should account for any emissions or energy consumption associated with the pyrolysis process. Consideration should also be given to any possible byproducts and their respective treatment or utilization. Ensure that all calculations are based on the functional unit of 1 ton of sludge with 80% moisture content. It is recommended to also consider the technological applicability of the given process in terms of scale, geographical location, and regulatory compliance.
