**Relevant quotes / tables:**

From Aboyade (Lumes):
> "MCF for Olusosun landfill was 0.8 as this satisfied the criteria of an unmanaged deep landfill... DOC value was found to be 0.19 based on the waste composition of MSW deposited in the landfill... DOCf was found to be 0.77 by assuming a landfill temperature of 35oC."

From NJT:
> "Based on the estimation of different parameters, Lo of 76.36 m3/ton was derived for Olusosun landfill... k value of 0.24 yr-1 was derived for Olushosun landfill."

| Parameter | Value |
|-----------|-------|
| MCF | 0.8 (unmanaged deep) |
| DOC | 0.19 |
| DOCf | 0.77 (at 35 °C) |
| L₀ (methane generation potential) | 76.36 m³/tonne |
| k (decay rate) | 0.24 yr⁻¹ |

Aboyade also reports a conservative L₀ of ~150 m³/Mg and k = 0.05 (IPCC default) in sensitivity work.

**What it feeds:**
- Site-specific landfill-gas parameters for Olushosun (Lagos).

**Confidence:** Medium for L₀/k/DOC; Low–Medium for MCF (classification depends on site depth/operation).

**Limitations:** Parameters derived by modelling with assumed temperature and waste composition; no direct long-term landfill-gas capture measurement reported.
