Moisture and Nitrogen Content of MSW was created by mubene
Hello,
I am currently working on modelling an AD from MSW process and was looking at the preset fuel characteristics of MSW. I noticed it doesn't include a moisture or nitrogen fraction. Is there a way to account for the moisture content if for example, I assume the MSW is only 20% solids?
I have seen some others ask similar questions and the reply has been to account for the moisture content by making up for it in the transportation emissions and increasing the distance. I'm not sure how exactly I could do that without being quite arbitrary.
Thank you,
Mitchell

The moisture content for the MSW is not an active cell in the model right now. We will look at making it active in the next version of the model..
The transportation adjustment doesn't have to be arbitrary. If you have 20% solids then you could increase the distance by a factor of 5 (1/0.2) since the emissions are a function of the tonnes-km moved.

Ok thank you. I also see the oxygen fraction is set to 0 for MSW, and there is no nitrogen fraction. If I wanted to change the values to match the CHNS-O content from literature would the rest of the LCA analysis update accordingly? And is there a method to include the nitrogen content?
Thanks,
Mitchell

The only parameter that is active in the MSW composition is the carbon content. The other parameters don't go anywhere.
The parameters for RDF (refuse derived fuel) are used in more places in the model. There are not many processes than can use MSW without some pre-treatment.
