The Glass Biogas Plant · Biogas

Secondary digester

Ventilation/dehumidification — the silent 24/7 load, with heat recovery. Part of the glass family — like our glass BESS, biogas plant and CHP.

What is the secondary digester?

The secondary digester uses the residual gas potential that leaves the main digester. What is not captured here escapes unused into the digestate store.

The plant — right now

Temperature, gas production and the flow from the main digester.

Read-only from the plant, calculated on site. Shown anonymously.

What the AI reads

Residual gas yield against what the main digester handed over
Temperature, because the secondary stage cools faster than the main one
Retention time against the actual throughput
Balance between the two stages, instead of reading each one alone

Monitored: continuously · residual gas against throughput

The scenario: Throughput is raised to gain capacity. Retention time in the secondary stage drops below what the residual conversion needs — the loss does not appear here, it appears as gas that is never produced.

Why it matters

The residual potential is gas that has already been paid for in substrate. Capturing it costs retention time, not raw material.
