The madness of woodchip as a bio fuel
/Half of the weight of a tree (when timber is dried) is carbon (approximately). In addition any pollution absorbed by the tree is present.
So when this is burnt for fuel, it releases the carbon and pollution.
Yet this is not included in BNG calculations or when Drax burns 12.86 million tons of wood per year……
On construction sites, the removal of organic matter from site, the pollution of the lorries that carry it to the power station or the carbon and pollution that is released into the atmosphere is not calculated in BNG / sustainability / Carbon sums.
In addition when it is considered in nature a tree grows, taking nutrients from the soil, then when it dies, it remains in situ and the nutrients in the tree are re-absorbed into the soil. There is no net loss of organic matter and the carbon is reabsorbed by the soil.
When organic matter is removed from site the soil is impoverished as the nutrients have been removed.
Yet this is not included in the BNG /Sustainability /Carbon calculations.
