The relative contribution of the orange juice processing to each impact category is shown in Figure 2-3. The
grey bar represents the cultivation of orange. The focus is on the impacts from the orange juice processing.
The main contributors to all impact categories are the electricity and thermal energy use. Indeed, the
electricity causes 20 % of the climate change and abiotic resource depletion impacts and 25% of the
acidification effects. The thermal energy use, i.e. natural gas, generates 15 % of the climate change and
abiotic resource depletion impacts. Another important process is the wastewater treatment that makes
almost 20 % of the freshwater eutrophication impacts. The contribution of other processes such as other
material use, e.g. detergents and cooling material, waste treatment, infrastructure is negligible.
