Current Result

The current research result, recommended path, scorecard, and decision outputs for turning sewage into fuel.

Recommended path

HTL-centered hybrid

Advance to integrated bench and controlled site-pilot design if Gate 1 and Gate 2 pass.

78Best current solution pathControlled pilot candidate
Current answerMedium

The recommended path is an HTL-centered hybrid: characterize sewage sludge, convert wet solids through HTL, treat or digest compatible aqueous organics, hydrotreat only validated biocrude, and keep residuals inside the permit boundary.

HTL has the strongest liquid-fuel signal for wet sludge, but fuel quality, aqueous phase behavior, PFAS, hydrogen, and residual handling remain scale-up gates.

Review evidence path
What should not be claimed yetHigh

The project should not claim finished drop-in fuel or carbon superiority until upgrading, hydrogen source, aqueous phase return, PFAS, residuals, TEA, and LCA are measured under one boundary.

The evidence register and validation protocol both show that reactor yield alone is insufficient for a practical sewage-to-fuel claim.

Review evidence path
Best near-term experimentHigh

Run a controlled bench program comparing AD-only, HTL-only, and HTL-plus-AD using the same sludge samples, mass balance, carbon ledger, and residual routing assumptions.

The experiment matrix already identifies feedstock assays, HTL screening, aqueous phase compatibility, hydrotreating, and integrated comparison as the shortest credible route to a go/no-go result.

Review evidence path
Commercial postureConditional

Proceed as a controlled pilot candidate, not a demonstration investment, until the integrated base case survives measured sidestream and upgrading penalties.

Economics can improve with avoided disposal, heat recovery, and low-carbon hydrogen, but those benefits must be site-specific and contracted before scale-up.

Result outputs

What the frontend should communicate now

Research lead

Research result

Continue with an HTL-centered hybrid as the leading solution architecture.

Only source-backed claims should be surfaced until measured integrated results are available.
Pilot lead

Pilot result

Prepare a controlled site-pilot package after feedstock and HTL balance gates pass.

Aqueous phase, PFAS, hydrotreating, and residual routing must be inside the pilot protocol.
Commercial lead

Commercial result

Keep demonstration financing conditional.

The base case must beat AD-only and current disposal without optimistic credits or excluded burdens.
Risk lead

Go/no-go result

Stop or revise the pathway if any non-fuel stream lacks a permitted, costed route.

PFAS, metals, aqueous phase, char, ash, and hydrochar are part of the result boundary.
