Zero-Waste Mine Reclamation: Coal + Steel + Human Wastes = Soil

by Zoe Dilles

Coal has seen a worldwide growth in production in recent decades despite health as well as environmental concerns as coal combustion is cited as the primary CO2 atmospheric source. In this age anthropogenic climate change, air emissions often overshadow the threats posed coalmine waste rock, which has far-reaching ecological effects from its metal and acid contents. Mixes of coal waste rock with other substances to balance the concentration of nutrients and minerals can order to promote plant growth. Fabricated soils have the potential to reduce landfill disposal as well as mitigate the issues attendant to reclamation reliant on borrowed soils, often leading to deforestation and hydrologic changes.
