[Biogas and biomethane](https://www.materialinsights.org/energy/biomethane/) (chemical) and [Milk & dairy](https://www.materialinsights.org/commodities/dairy/) (commodity): 2 relationships.

## How they are linked

### 1. Feedstock

*Physical flow · Direct · Milk & dairy → Biogas and biomethane*

Biogas and biomethane is made from milk & dairy: it is one of the raw materials its production routes start from.

### 2. Price link: manure feedstock

*Cost and price · Moderate · Both ways*

Cattle manure is a main biogas feedstock, and dairy farms host many digesters. Milk prices do not set manure supply, so monthly moves correlate at only 0.07 with the gas proxy.
