One Big New Advantage of Anaerobic Digestion to Replace Depleted Land Ca...

A Big New Advantage of Anaerobic Digestion

The UK’s Committee on Climate Change (CCC) is the body which advises on how the UK will meet its obligations to reduce climate change, in the “Paris Agreement”.

It has come up with a new advantage of anaerobic digestion, to raise carbon biomass in agricultural soils.

No-one can deny that all governments need to help reduce climate change.

Climate change threatens the land’s ability to provide critical services including clean water, healthy soils and timber, and ensure sufficient food production for an increasing population, and threatens to reduce space for new homes.

They say that a good way to reduce the climate change arising from excess carbon (CO2) in the atmosphere is to hold more carbon in the land (soil).

At the same time this would improve soil fertility, and provide more food.

So, they are recommending that fundamental reform is implemented to ensure land becomes a more effective carbon store.

To store this carbon a source of suitable organic material will be needed.

Biogas Plants (anaerobic digestion processes) are ideally suited to providing this, by creating the necessary carbon for return to the land, from their fertilizing output, known as digestate.

This is a newly discovered advantage of Anaerobic Digestion, to add to the existing advantages, the biggest of which is the production of renewable energy in the form of biogas.
