I am seeking to clarify the difference between APOS and Cut-Off datasets. I have read through the EcoInvent online material but am finding the jargon used in the explanations tough to understand.
I have created a project comparing Waste PET parameter across APOS (U) and Cut-Off (U) product systems. The cut-off (U) decreases for Ionizing Radiation Impact, whereas the APOS (U) decreases for Terrestrial Ecotoxicity Impacts, otherwise they remain equal in all other impacts.
I am unable to describe why this is happening. Cut-off is using `burden free` recyclable materials and by-products? But why is that affecting these specific impacts?
Thank you for help!
