Restoration: Biochar is being used to facilitate abandoned mine cleanups

Here’s an infographic created by Kimberly Hiral for the High Country News explaining the application of biochar in abandoned mine cleanup. From the article:

To help revegetate and stabilize the acidic, plant-hostile soils around mine sites, scientists are borrowing a technique from agricultural research: They apply biochar, a charcoal formed by heating plant and wood waste in the absence of oxygen, to the soil. The carbon-dense char, used to boost soil fertility on farms, helps plants get established in barren mine sites, reducing contaminated runoff.
