The sludge obtained from the centrifuge on LS is filtered, with an energy consumption of 43.2 Je/FU. The waste stream of this step, comprised of the exhausted filter and vapor mass loss (30 g), is assumed to be managed as "hazardous waste", with emissions taken from Ecoinvent database. 24 VII) Drying (LS). This step is required to evaporate the water fraction and the residual limonene (not recycled) in the sludge from the pumping step. The heat consumption of the oven is estimated to be 3.1 MJt/FU. The amount of evaporated limonene, estimated to be 90 g/FU trough the mass balance, is burned and assumed to be totally converted in CO2 (stoichiometric approach), which is accordingly emitted to the atmosphere.
