Accordingly, the constructed process models estimate that 13.2 kg mixed organic waste per kg paracetamol produced could not be recycled within the modelled process and required disposal. Ideally, this waste should be exported for use in other process plants as low-grade solvents or feed streams. However, uncertainty regarding the extent and compositions of the organic waste streams made sales predictions at this early design stage impossible. Instead, it was assumed that all residual organic wastes needed to be eliminated via incineration.
