Ash, spread either by ground-based equipment or from the air, is recycled either directly or is manipulated into a more localized, site-specific product.
Generally, ash is manipulated in two ways:
1) by the addition or subtraction of select elements and
2) by changing its physical properties via hardening, granulation, or
pelletizing.
Spreading ash with ground-based equipment is the most cost efficient and precise form of distribution. However, it requires substantial planning because of environmental and logistical concerns. Aerial application is more expensive. However, there are less environmental concerns. Application can occur at any time of the year with no soil disturbance.
