The treatments of aqueous and organic waste streams generated throughout the paracetamol synthesis process were not investigated experimentally, thus no primary data was available to estimate the environmental impacts of treating process wastes. Furthermore, no suitable preassembled LCI datasets for industrial waste treatment were available in ecoinvent v3.7 to approximate the impacts of waste treatment. To obtain a cradle-to-gate LCA for the novel process without available primary or proxy data on waste treatment processes, inventory models for waste treatment were constructed using literature-derived LCI models, as outlined below.
