Scotland completes first 'gas to grid' anaerobic digestion project

Scotland’s first “gas to grid” anaerobic digestion project in Coupar Angus, Perthshire, came online towards the end of 2014, The Scotsman has reported.

A number of other projects are also currently in various stages of development.

Anaerobic digestion (AD) is a natural process where, in the absence of oxygen, organic material is broken down by bacteria to produce biogas.

The recent headlines in relation to milk pricing further emphasise the need for farmers to continue to look for means of diversification.

Using slurry, silage and crops as AD feedstock means financially advantageous, stable, long-term supply agreements for farmers.

In addition, the by-product of the process is a nutrient-rich organic fertiliser that can be returned to the fields.
