Goal and Scope of LCA System allocation approach How are the impacts and benefits of recycling and recovery processes considered in the system model? Base scenarios: Allocation factor 5% Half of the burdens and credits from recovery and recycling processes are allocated to the system under examination, the other half is allocated to the subsequent system. Sensitivity analysis: Allocation factor % All burdens and credits are allocated to the system under study. Results of one allocation approach are not more correct than those of another. ISO requirements: Application of two different allocation approaches to verify the influence of this methological choice on the results. 14

Goal and Scope of LCA Environmental impact assessment Impact categories Climate Change Stratospheric Ozone Depletion Photo-Oxidant Formation Acidification Description Addresses the impact of anthropogenic emissions on the radiative forcing of the atmosphere. Greenhouse gas emissions enhance the radiative forcing, resulting in an increase of the earth s temperature. Anthropogenic impact on the earth s atmosphere, which leads to the decomposition of naturally present ozone molecules, thus disturbing the ozone layer in the stratosphere. Also known as summer smog, is the photochemical creation of reactive substances (mainly ozone), which affect human health and ecosystems. This ground-level ozone is formed in the atmosphere by nitrogen oxides and volatile organic compounds in the presence of sunlight. Affects aquatic and terrestrial ecosystems by changing the acid-basic-equilibrium through the input of acidifying substances. Terrestrial Eutrophication Aquatic Eutrophication Eutrophication means the excessive supply of nutrients and can apply to both surface waters and soils. terrestrial: eutrophication of soils by athmospheric emissions aquatic: eutrophication of water bodies by effluent releases Particulate Matter Covers effects of fine particulates with an aerodynamic diameter of less than 2.5 µm (PM 2.5) emitted directly or formed from precursors as NO x and SO 2. A correlation between the exposure to particulate matter and the mortality from respiratory diseases as well as a weakening of the immune system exists. Total Primary Energy Quantification of the primary energy consumption of a system. It is calculated by adding the energy content of all used fossil fuels, nuclear and renewable energy (including biomass). Non-renewable Primary Energy 16 Considers the primary energy consumption d on non-renewable, i.e. fossil and nuclear energy sources.

Apart from the electricity grid mix, recycling rates are one of the major parameters expected to differ considerably between countries.
Conclusions Most significant parameters Major impact in most of environmental impact indicators in both markets due to the production of materials, especially the production of plastics, aluminium, tinplate and glass. Production of LPB for plays a less important role in many impact categories. But LPB still main contributor to the results of in Aquatic Eutrophication, Summer Smog, Acidification, Terrestrial Eutrophication and Particulate Matter. Included polymers in cause high contribution to the Ozone Depletion Potential. Production of of glass jar and steel can shows high contributions in Aquatic Eutrophication potential. Transport related impacts of glass jar and steel can in Terrestrial Eutrophication and Summer Smog. Impacts for scope of are higher due to the longer transport distances. High share of and glass jar due to land in : major contribution to Aquatic Eutrophication, however to a lesser extent for. 61
Conclusions Comparison of TRC with competing systems shows higher environmental impacts in all impact categories compared to, except in Aquatic Eutrophication. Steel can shows higher environmental impacts in all impact categories than except in Aquatic Eutrophication and Ozone Depletion Potential: Results of the can match those of the within the scope of if an allocation factor of % is applied. The robustness and validity of the results regarding the allocation factor used for open-loop recycling are generally confirmed by the sensitivity analyses. The sensitivity analysis with varying recycling rates for the alternative packaging systems on the European market confirms the pattern, when the is compared with the glass jar and steel can. Findings are only valid within this LCA study s framework conditions. Accordingly, several limitations must be considered and are documented in detail in the full report. 62
Overarching conclusions and recommendations Food carton clearly shows a more favourable environmental performance compared to glass jar and steel can. The robustness and validity of the results are confirmed by the applied sensitivity scenarios regarding the allocation factor and varying recycling rates for glass jar and steel can. Environmental impacts of are primarily defined by the production of materials for primary packaging. The share of LPB made of renewable sources, the production of it using a high share of renewable energy sources and the lightweight of are an advantage. Optimisation efforts for the should be directed towards the weight and type of polymers included in. 63
