Climate pollution from wind farms on peat 'underestimated'
Wind farms on Scotland's peatland could be doing much more damage to the climate than previously thought. The volume of greenhouse gases released when turbines and tracks are built on peat could be "significantly" underestimated, experts have told The Ferret. Peat-rich Shetland has become the epicentre of this debate – with the Scottish ...

Dehydration and upgrading of peat and lignite
The Koppelman process for irreversible drying and upgrading of low value fuels has been applied to peat from various sources. The paper describes an adaptation of the Koppelman process in which peat is hydraulically mined and pipelined as a slurry to a plant where it is converted to a high quality solid fuel, designated as K-Fuel.

What is the effect of dewatering on the soil.
Dewatering can make the ground lose coherence; the result leads to ground settling. If the ground settling is vast, it can harm close by building and structures. When groundwater is removed from the soil, it makes the soil pack and squeeze. It can likewise also caused by small soil & shallow grounds being removed with the groundwater …
