Continue Lab work
• Database is stored locally
• Same computer as last week
• You can import a database
• Database is on polybox: Professional_2015-09-28_11-23-07_bottle
• Description: How to import and export database in simapro 8

4. Save the database under a new name:
5. Open the database and create a new project.
3. Agree to restore the database:
Model a material
• Material a: 20gr of Plastic bottle • 22gr of PET (RER, S)

Work on your own: 10min
Have a look at the network
10
www.ifu.ethz.ch/ESD
Analyze options: tree, network, comparison
Select method
Calculate
Have a look at the network
• See how the life cycle is taking form
• Cradle to gate level/ not LC yet
• Main features of the Network
• Take a look at the inventory list
11
www.ifu.ethz.ch/ESD
Model the life cycle
• 1 water bottle of 23g
• 2x 50km transport, lorry 20-28 ton
• Disposal to incineration scenario CH
13
www.ifu.ethz.ch/ESD
Use unit processes
Modeling details
• Modeling transport
• “ton x km” or “kg x km”
• 50% loaded, full to go & empty on return

Have a look at the network
• See how the life cycle is taking form
• Main features of the network
• Different options
15
www.ifu.ethz.ch/ESD
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?

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
41
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‘
42

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
43
www.ifu.ethz.ch/ESD
Switches: • Local: Distance <=50km
• Regional: 50km<distance and distance>150km
• Abroad: Distance=>150km
Exercise 6.3: Different distances-different transport
• 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
44
www.ifu.ethz.ch/ESD
Scenario Distance Transport mode
1. Local Smaller or equal than 50km van < 3,5t/RER S
2. Regional Between 50 and 150km Lorry of 16t, fleet average/RER
3. Abroad Bigger or equal than 150km Lorry of 20-28t, fleet average/RER
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
