Hello,
Please i want to know how i will make a percentage contribution of my input that contributed to these impacts. Here I have some waste treatment INCLUDED IN MY INPUT and I found out these WASTE TREATMENTS RECORDED NEGATIVE IMPACTS VALUES.
Example, if my perecentage contribution considering the NEGATIVE VALUE FROM WASTE TREATMENT IN THE INPUT HAS -81% in a subsystem and in another it has positive values examples below:
Lyophilization=74%,Post.elution.purification=6%,cultivation=0%,gene.insertion=-84%
Is it reasonable to leave out environmental savings as negative sign (-84%) from waste treatment or balance the percentage to make it a positive value instead in an attributional LCA paper? should a negative value refelect in percentage contribution when considering ALCA? usually, Consequential usually have this negative savings |
