Provide control over fertilizer offset in anaerobic digestion #4

Open WesIngwersen opened 2 years ago

WesIngwersen commented 2 years ago

related to #2 and #3, Carbon dioxide/Emissions to air/unspecified that appears as an elementary flow in Anaerobic digestion processes would be better modeled as an avoided product like with electricity emissions in #3. As it's modeled now it would appear that CO2 was absorbed during the anaerobic digestion process

Here is what is looks like in olca image

As discussed with @a-w-beck, this will require a major enhancement through an ability to create new processes in WARMer, because there are not existing processes for N and P fertilizer use in WARM

Processes which then will need to be mapped (and priced) to useeio via processmapping.csv

WesIngwersen commented 2 years ago

Any process mapping should be model specific and therefore not present in WARMer, which we have recently clarified is independent of useeio or any other LCA model. If this file is intended to be specific to useeio it could be in HIO

So I initially referenced this issue (the wrong one) in commit 4ef9e198ab392bc7fbd7ace12dc9a5cc3fb0c035 and then amended it to the correct one (#3), but there's no way to remove the link here on GH. Whoops!

We currently use the Food Waste AD fertilizer offset rates for all AD processes, but instead these offset rates shoud vary by material type [WARM Management Practices Chapters, s.3.2.8]:
