About modeling the end of life

[zg4248s]

Hallo all,

i am a new user of the software and i have a question when I model the products' end of life stage.
I was expecting that the LCIA result of the end of life would be negative, cause there are secondary products coming out as output
There is one process in the software called "treatment" and I calculate with this process, but the results are actually positive.
I would really appreciate if some could help.

Best regards,
Raymond
