1. Handouts SimaPro: Life Cycle Assessment software

Case 1: plastic water bottle

1.Model water bottle using ecoinvent unit processes 1.1 Model a material: water bottle, cap The production of a water bottle consists of a bottle, a cap and bottling process 20gr of plastic bottle Input/Output Input in SimaPro 22gr of PET Polyethylene terephthalate, granulate, bottle grade, at plant/RER S 2. Materials/fuels Blow moulding of the plastic Blow moulding/RER S 2g waste during the Disposal, polyethylene terephtalate, 0.2% Outputs. Treatment production water, to municipal incineration/CH S

3gr of plastic cap Input/Output Input in SimaPro 3.75gr ABS Acrylonitrile-butadiene-styrene copolymer, 4. Materials/fuels ABS, at plant/RER S 0.75gr of waste during Disposal, plastics, mixture, 15.3% water, Outputs. Treatment production to municipal incineration/CH S

1.2 Combine your materials: water bottle plus cap 1p of plastic bottle Input/Output Input in SimaPro 20gr of bottle See section 1.1 5. Materials/fuels/el 3gr of cap See section 1.1 ectricity Pumping, purifying, and 0.02 kWh Electricity, medium voltage, filling production UCTE, at grid/UCTE S

1.3 Model the life cycle 1p life cycle Input/Output Input in SimaPro Water bottle plus cap See section 1.2 7. Materials/fuels 2*50km of transport Transport, lorry 20-28t, fleet average/CH S Disposal of the bottle to Disposal, plastics, mixture, 15.3% water, Outputs. Treatment incineration to municipal incineration/CH S

Case 2: glass water bottle Model consistent with the plastic bottle, so that both life cycles can be compared!
