• Learn how to model in SimaPro
• Model the production of a plastic water bottle
Non reusable plastic bottle
www.ifu.ethz.ch/ESD
Model a material (under processes)
Choose a folder or
make a new one
New material
13
www.ifu.ethz.ch/ESD
Model a material (under processes)
Name of the material
Input materials and
processes
Emissions to air, water and
soil.
14
www.ifu.ethz.ch/ESD
Waste type
• Within SimaPro each material is send to waste scenario
• Waste scenario describes where waste is going
• Waste treatment describes the emissions per kg waste
land filled or burned
• This is based on the waste type
You flag the material
Waste scenario send waste to specific waste treatment

IMPACT ASSESSMENT IN SIMAPRO
Characterisation, normalization,…
Result interpretation:
• Analyse if the flows make sense
• Look at the network with a 0,1 % cut-off
• How much material goes in the system
• How much material goes of the system to the waste
scenario?
• What are the processes that contribute with most of
the impact
• Check the thicknesses of the arrows

EXERCISE 6:
MODEL WITH PARAMETERS (APPLY TO PLASTIC BOTTLE)
Model with parameters
Insert a variable instead of constant data
When??
• Preliminary data is available, inputs could change if better data is available
• Different input values can be used to calculate more versions of the same life
cycle
• Reduce the possibility of making calculation mistakes. Easy to check
• Insert calculation rules instead of constant data as input data.
• Available for all processes and product stages
• With or without uncertainty distribution
• Calculation rule:
• Defined in SimaPro
• Based on input parameter
51
www.ifu.ethz.ch/ESD
Exercise 6.1: Model bottling with parameters
• Electricity use for bottling
• Uncertain value
• Combination of values
• Input parameters (apply to plastic bottle)
• ‘pumping&cleaning’: 0.015kWh/l
• ‘filling ’: 0.005kWh/l
• Calculated parameter
• bottling=‘pumping&cleaning + filling’
• Process input data
• ‘bottling‘
52
www.ifu.ethz.ch/ESD
Exercise 6.2: Model transport with parameters
• Use Input parameters for distance and weight
• Use a calculated parameter for transport
• Replace transport within case study 1 by a calculation rule
53
www.ifu.ethz.ch/ESD
Exercise 6.3: Different distances-different transport
Scenario
Distance
1. Local
• 50km
Local: Distance
<=50km
Smaller or equal than
van
< 3,5t/RER S
• Regional: 50km<distance
Between 50 and 150km
Lorry of 16t,and
fleetdistance>150km
average/RER
• Abroad: Distance=>150km
Bigger or equal than 150km
Lorry of 20-28t, fleet average/RER
2. Regional
3. Abroad
Switches:
Transport mode
• Process sheet:
• Parameter tap: Make the necessary switch parameters
which are 1 when the distance is conform the scenario
• In the input for transport: add two lines for the transport with a van and transport with lorry
20-28t. Multiply inputs by the corresponding switches
54
www.ifu.ethz.ch/ESD
Compare different versions of your model
• First parameters are defined at process/project or database level
• A Calculation setup can be used to define two or more scenarios
• Each scenario considers different values for the parameter
