Fly-ash is a hazardous environmental byproduct from coal-fired electric power generation and industrial boilers.
For decades, utilities have disposed of coal ash dangerously, dumping it in unlined ponds and landfills where the toxins leak into groundwater. Some estimates state there are over 3 billion tons of legacy and “fresh” fly-ash waste in the U.S. alone. Many landfills and collection ponds are near large cities.
According to industry’s own data, 94% of the coal ash ponds in the United States are unlined. Unlined ponds are contaminating groundwater with toxins above levels that the U.S. Environmental Protection Agency deems safe for drinking water.
Legal and technical experts from Earthjustice, the Environmental Integrity Project, and partner organizations located and analyzed the data disclosures from utilities that report groundwater monitoring data and found that 91% of these plants are contaminating groundwater with toxic substances at levels exceeding federal safe standards.
AquiPor’s permeable concrete can be used to sequester various harmful industrial waste by combining these materials with our catalytic binder. One such waste material we have been successfully testing in our mix designs is fly ash.
There are environmental and economic advantages to recycling this waste back into our concrete, but in addition to that, it creates some emerging properties that are very compelling for our permeable technology.
How about that...taking care of industrial waste that is contaminating groundwater and putting it into new, useful permeable material that can help improve groundwater and freshwater in our cities?!
