(1) | Material consumption no. of kg of material [A] x mPR/kg for [A] = mPR for material [A] |
(2) | Primary energy consumption Amount of material [kg ] x primary energy for the material [Mj/kg] = primary energy consumption [Mj] |
(3) | Conversion of energy Electricity consumption [MJ] x 2.5 = primary energy consumption [MJ] |
(4) | Conversion of energy Electricity consumption [kWh] x 9 = primary energy consumption [MJ] |
(5) | Energy contents in energy resources Energy resource [kg] x calorific value [MJ/kg] = primary energy consumption [MJ] |
(6) | Energy contents on incineration Material [kg] x calorific value [MJ/kg] = heat generation [MJ] |
(7) | Energy consumption during transport The sum of: (transported material [kg] x distance [km] x nergy consumption [MJ/(kg x km)]) = total energy consumption[MJ] |
(8) | Consumption of energy resources Energy consumption [MJ] / 1,025 [MJ/mPR oil] = consumption of oil resources [mPR] |
