2. Tutorial

The G-BOM analyzer interface:

1b) GHG emission database

Data input examples:

1. High-density polyethylene (HDPE) 0.685kg (database)

2. black pigment 0.05kg (self-define)

Click 'search' to enter the GHG emission database, and select the materials of the components.

i) Method 1- select the material according to its stage and category.

Example: High-density polyethylene (HDPE)

Or enter a keyword in the search engine and all related items will be shown when you click into different stage.

Sources of database:

  Database Region
1 Ecoinvent 2.2 Ecoinvent 2.2 Europe
2 JEMAI Japan Environmental Management Association for Industry Japan
3 Korean LCI Korea Life Cycle Inventory(LCI) Database Korea
4 Taiwan EPA Taiwan's Environmental Protection Administration Taiwan
5 PolyU GME Research Group PolyU ISE Ecodesign and Green Manufacturing Research Group Hong Kong

 

ii) Method 2- enter the emission factor for materials that are not included in the data base.

Examples: Black pigments form ABC company; unit (kg); carbon footprint emission factor (1.2 kg CO2-eq/ kg)

 

1c) Sequence of data entry

i) Import the relative material from the GHG emission database.

ii) Enter the quantity of the materials and click 'Save'.

Remarks: The component name will not be shown in the pull down manual once it is selected and saved.

iii) Repeat the procedures in 1b) to 1c) to add new components and click 'Next' to move on to next stage after finish data entry in this stage.
