SUPPORTING INFORMATION
Enthalpy data and toxicity score for all reactants and products
The enthalpies of combustion and formation are determined based on Joback’s group
contribution method [1,2] and the method by Marrero & Gani [2]. The toxicity score TS is
determined based on the classification of R-phrases. The upper bound of the TS is set to 1000
representing the maximal value in the TS classification [3,4].

Environmental impact
The simplified version of the EI calculation relies on energy consumption (EC), resource
consumption (RC), emission impact (Em) and toxicity potential (TP). Equations (A1) to (A4)
show the formulae for the individual factors:
�� = ∆������∙ ����
(A1) �� = ∑ �������������
�����∙ ���� (A2)
�� = ����∙ ��������∙ ����
(A3) �� = � !"#$ % !"#$ &'����())) (A4)
Em not only accounts for CO2 emissions, but also for the CO2-equivalent of other gas
emissions with global warming potential. For the determination of the toxicity potential,
components with a high molecular similarity are classified similarly (same toxicity score), when
no risk and safety sentences are available. This avoids a misinterpretation of the toxicity
potential due to a non-existing toxicity classification, which is often the case for newly
developed molecules. As outlined in [3,4], the toxicity score TS is classified into harmless (TS: 0-
300) and injuring effects (TS > 300). Ethanol has a TS of 0, which causes problems since the
toxicity potential would be omitted due to a resulting weighting factor of 0. Hence all fuel
candidates exhibiting a toxicity score of 0 or 100 are set to TS of 300. Due to the classification
into harmless and injuring effects, this approach does not change the general statement, whether
a molecule is harmless or not.
Standardization of the environmental impact
To avoid a dependency of the normalization on the case study, the four single impacts are
weighted based on the reference production of ethanol (cf. Eq. (3)), which exhibits an EI of 1.
All impacts contribute equally (25%) to the EI in case of ethanol. The normalization is based on

value of 2.77·1012 kJ/year. Equations (A5) to (A8) show the calculation of the weighting factors:

The calculation of the energy loss ∆�� 67 requires the enthalpy of combustion of all educts
and of the product ethanol; this data is compiled in Table A1. For each mole of ethanol one mole
of CO2 is released during fermentation. With this information the individual factors for ethanol
and the weighting factors can be calculated as follows:
��� 67[:;<=] = 20.17 → *�+ = 0.013 [<=:;]

Reaction yields and references
Reaction yields have been collected from literature and are compiled in Table A2. Unknown
reaction yields are marked and set to 0.97. The split of lignin into its constituents is assumed to
be ideal and marked with “Assumption Lignin”. The split between the lignin alcohols is
implemented using optimization constraints. The upper bound of the reaction yields is 1 in case
of chemical conversions representing the theoretical yield. The determination of the theoretical
yield differs for the fermentations. The upper bound in case of ethanol is 0.51 g/g (R8), for
itaconic acid 0.72 g/g (R9), for butanol 0.5 g/g (R10) and in case of succinic acid 1.1 g/g (R50)
respectively.

influence. The weighting factors of the EI, the property data and toxicity score as well as the
reaction yields are presented in Tables 1, A1 and A2. In addition, the parameters determining the
cost calculations as well as lower and upper bound of biomass composition are presented in

Influence of the parameter Invest2 on the sensitivity analysis
The OAT as well as the MC analysis identified the parameter Invest2 as the most influential
parameter. Therefore a detailed discussion and quantification of this parameter’s influence is
conducted in the following. Figure 1 shows the comparison of the results of OAT analysis with
and without considering the parameter Invest2 in the sensitivity analysis. In addition, Table A4
quantifies the maximum relative deviations from the results of the RNFA for nominal parameters
with and without considering the parameter Invest2 for the case of minimal TAC.

Both, the graphical comparison as well as the quantification of the maximal relative deviations
underline the statement of the high influence of the cost coefficient on the process analysis. But
there exist also distinct differences for the different fuel candidates and their respective
production processes. While the cost coefficient clearly has a high influence for cylohexanol,
there is no influence on the process performance for methane. This might be due to the very low
TAC of the methane process compared to the cyclohexanol process. The most stable behaviour
considering all parameter variations are shown for the fuel candidates 2-MTHF, EL, PUD and
ethanol, which exhibit an uncertainty range of ±46% in the TAC. Without the consideration of

the parameter Invest2, for all fuel candidates except methane, the TAC are within a range of
±33% compared to the nominal cases. Hence the high influence of the parameter Invest2 can be
proven by the results of OAT analysis. Figure 2 presents the analogue comparison for the MC
analysis. Both analyses show the strong influence of the cost coefficient Invest2 for each top-
scorer.
