Any declared benefits and loads from net flows leaving the product system that have not been allocated as co- products and that have passed the end-of-waste state are included in module D. Such declared benefits can for ROCKWOOL products occur in stages A5, C3 and C4. The generated energy, such as heat and electricity from waste incineration of packaging is assigned to module D. The benefits are calculated using current average substitution processes. The heat is credited for with heat from natural gas. The electricity is credited for with the specific country’s electricity mix. This is also applied for materials that are landfilled as the avoided impact of electricity production and/or thermal energy recovery from landfill gas recovery is included in module D. For the recycling of stone wool it is important that no double counting occurs. The outputs of waste stone wool from modules A5 and C1 are considered linked to the inputs of waste stone wool into A1. Therefore only the net output flow (output from A5
