TRU faculty member Dr. Garrett Whitworth presents a talk called Identifying a beneficial use for an industrial by-product.


Biomass fuelled power plants produce ash residuals as a by-product to power generation.

These ash residuals are full of nutrients, however, due to their high pH, they are usually transferred to landfills.

We have identified a chemical amendment that is environmentally safe and reduces the pH of the ash residuals to a level that would be suitable for use as an agricultural fertilizer.

Studies are currently underway, on an industrial scale, to identify the beneficial uses of amended ash residuals through the use of soil sampling and drone-based crop health monitoring with the goal of reducing the amount of ash residuals that end up in landfills.
