🌍 Integrated LCA + TEA Dashboard

LCA System Inventory (per FU)

t/FU
Mass of biomass/feedstock entering the process.
t/FU
Mass of main product leaving the gate.
t/FU
Optional secondary product; set to 0 if none.
t/FU
E.g., ash, char, sludge cake.
t/FU
TOTAL liquid waste mass (e.g., wastewater, purge).
t/FU
TOTAL gas waste mass vented/treated (not product gas).
t/FU
Make-up water, moisture, solvents counted as water-equivalent.
t/FU
Only use if you explicitly want air mass tracked (often excluded in gate balances).
t/FU
Water leaving as vapor (drying, vents, evaporation).
t/FU
For mass balance only. Does NOT imply fossil GHG without carbon accounting.
t/FU
Chemicals, catalysts, solvents etc. screening term.
t/FU
Untracked outputs not covered above screening term.

Energy + Logistics (per FU)

km
kg/(t·km)
kWh/FU
kg/kWh
MJ/FU
Set 0 if not used.
kg/MJ
Replace with your factor (fuel/steam source).
kWh/FU
Credit uses Grid EF.
MJ/FU
Credit uses Heat EF.

Interaction + caveats
• Screening-level. Document factors and credit assumptions. Do sensitivity/uncertainty checks.
• Ctrl/⌘+Enter runs the model on the active tab.
• Emissions breakdown shows credits as negative contributions.
• Energy chart uses kWh-equivalent for heat (1 kWh = 3.6 MJ) for visualization only.

Mass balance (t/FU)

Only tonne-based flows. Quick check, not a full elemental balance.

Energy (kWh-eq/FU)

Heat converted to kWh-equivalent using 1 kWh = 3.6 MJ for plotting.

Sensitivity analysis (one-way tornado)

Varies one parameter at a time around the current inputs. Default uses ±% perturbation. Run LCA/TEA first for the chosen metric.
Choose what the tornado chart shows.
Example: 20 = ±20% around baseline.
Sorted by absolute impact.
Parameters included

Notes

One-way sensitivity does not capture parameter correlations or nonlinear interaction effects. For uncertainty, assign distributions and run Monte Carlo.

Integrated Results

Quick notes

Screening tool only. Biggest uncertainties often: waste treatment EFs, energy EFs, and displacement/credit assumptions. For decisions, use documented sources and formal uncertainty (e.g., distributions + Monte Carlo).
