Methane and potential avoided emissions

Estimated methane per tonne of food
108.4 Nm³ / t
Potential avoided fossil gas emissions (methane) — per tonne of food
156.1 kg CO₂e / t
Estimated methane for the load
2,536.0 Nm³
Potential avoided fossil gas emissions (methane) — per load
3,651.8 kg CO₂e

(Methane released into the atmosphere has a significantly greater warming effect than carbon dioxide, so preventing leaks matters.)

Method and limitations

Illustrative estimate—not for reporting. Fictional sample load and customer; not a saved assessment, certification or independent verification.

Methane is theoretical potential, not raw biogas volume or upgraded biomethane. All fibre is treated as digestible, making this an upper estimate; sugars and saturates are not counted again.

Potential avoided fossil gas emissions use assumed methane production, then the share actually replacing fossil gas after losses and internal consumption. 100% replacement is an upper-bound illustration, not measured plant performance.

Estimates assume food in the condition described by the label or reference values. Age, decay, mould, damaged packaging, contamination, storage conditions and plant operation may reduce actual gas yield.

(Methane released into the atmosphere has a significantly greater warming effect than carbon dioxide, so preventing leaks matters.)

This is not a net carbon saving. AD processing, leakage emissions, packaging disposal and other plant impacts are not deducted. Transport remains separate; no treatment-route comparison is made.

Methane uses net food weight; transport carries gross load weight. Methane generation alone does not establish avoided emissions.
