Parameter changes are treated as process changes with mechanical consequences.
Pilot Modeling
Use the 3D system surface with scenario metrics to pressure-test assumptions before promoting claims into external narratives.

Feedstock basins
Influent composition and solids handling remain central to every model run.
Bench sample
Sandbox assumptions should be checked against measured material behavior.

Universa Bio Fuel Universa Bio Fuel is an exploratory research and decision platform for sewage-to-fuel conversion: treating municipal wastewater sludge as a wet carbon feedstock and evaluating whether it can be converted into usable oil-based fuel intermediates under realistic technical, biological, environmental, and economic boundaries. The current leading architecture is an HTL-centered hybrid: convert wet sludge to biocrude, prove aqueous-phase and residual handling, upgrade representative biocrude through hydrotreating, and compare the result against anaerobic digestion, SCWG/SCWO, HTC, pyrolysis, gasification, and current sludge disposal. The repository does not claim the fuel is ready for use; product quality, biosecurity, contaminants, TEA, LCA, and permitting still require measured validation.
First-Pass Assumptions Reference IDs in this file point to the bibliography. Scope This file defines the boundary rules for the first-pass sewage-to-bio-oil carbon ledger. The model is intentionally normalized and boundary-driven.
Reference Case Reference IDs in this file point to the bibliography. Chosen Baseline The current wastewater comparison baseline for this repository is: conventional wastewater solids processing with anaerobic digestion and onsite biogas use Why This Baseline This is the right first comparison because: anaerobic digestion is already a standard and widely used pathway for wastewater solids (R11, R12) it produces recoverable energy in the form of biogas rather than leaving the project to compare only against fossil fuels (R11, R12, R13) full-scale studies show that sludge-line optimization can already move wastewater plants toward higher energy self-sufficiency without creating a new liquid-fuel pathway (R13, R17) What This Baseline Includes wastewater solids stabilization biogas production onsite energy use from biogas nutrient-containing residual solids direct-emission relevance from wastewater handling What This Baseline Does Not Mean It does not mean: every plant operates an optimized digester anaerobic digestion is automatically the best possible wastewater pathway anaerobic digestion and sewage-to-bio-oil target the same final product It means only that AD is the most credible incumbent baseline the new concept must beat or complement. Why Not Use Untreated Sewage as the Reference Using untreated sewage as the main comparison would exaggerate the apparent benefit of the sewage-to-bio-oil concept.
Scenario Definitions Purpose These scenarios define how the first-pass carbon ledger should be interpreted before the repository has validated performance numbers. Current Scenario Values These values are explicit stress-test hypotheses for the sewage-to-bio-oil concept. They are not evidence-backed performance claims.
